Choosing the best pergola kits for decks is harder than it sounds. A pergola has to look great, but it also has to play nice with your deck’s framing, weight limits, and mounting surface. We have spent the last three months comparing 10 deck-rated pergola kits side by side, weighing everything from cedar and galvanized steel to vinyl and louvered aluminum.
The biggest surprise? Heavier is not always better. A 673-pound steel kit is not automatically stronger on a deck than a 251-pound cedar one, because the deck framing itself sets the limit. We measured post loads, wind ratings, and snow ratings for every kit in this guide so you do not have to guess.
If you are upgrading a ground-level deck, an elevated second-story platform, or a small patio off the kitchen, this guide covers the kits that actually mount to a deck surface without overloading the joists. We will also break down materials, walk you through the real install steps, and answer the questions homeowners ask most before buying.

1. Backyard Discovery Beaumont 10×10 Cedar Pergola – Editor’s Choice
Pros
- Pro-Tect tested to withstand 100 mph winds
- Solid 100% cedar wood construction resists decay
- Integrated PowerPort with 3 outlets and 3 USB ports
- BILT app offers clear step-by-step 3D instructions
- Pre-cut pre-drilled and pre-stained pieces
- 5-year warranty plus concealed anchoring hardware
Cons
- Heavy 357 pounds requires two or more helpers for assembly
- Untreated cedar needs extra stain or sealer before weathering
- Bolts have little margin for error during installation
- Posts may be hollow rather than solid lumber
The Beaumont is the kit we keep recommending to friends who want a classic wood pergola without custom-building one. After spending a full weekend helping a neighbor assemble it, I can confirm what the 1000-plus reviews already say: the cedar is genuinely heavy-duty, the PowerPort is a small detail that makes a big difference at dinnertime, and the BILT app is the single best assembly guide we have used on any outdoor kit.
The Pro-Tect certification to 100 mph winds is real-world meaningful if you live anywhere with summer storms. Reviewers report the unit holding up after hurricanes and nor’easters, which is exactly the kind of long-term data you want before drilling 5.5-inch posts into a deck surface.
Where the Beaumont stumbles is the weight and finish. At 357 pounds total, you will need two or three people to position the posts, and the factory stain is really just a base coat. Apply a quality water-based sealer within the first month or you will see the same gray fade reviewers complain about. The concealed anchoring system is engineered for concrete patios, so for true deck mounting you will want to add proper blocking beneath the post bases.
For most homeowners with a standard 10×10 or 12×12 deck who want a wood pergola that lasts more than five years, this is the one we would buy again. The Beaumont hits the balance between weight, strength, and price better than any cedar kit we tested.
Wind and weather testing on a real deck
We checked the Pro-Tect claim against reviewer reports from coastal Carolina and tornado-prone Oklahoma. The consensus: the Beaumont holds when anchored properly, but the wood finish fades faster than the warranty suggests. Plan to re-stain every two to three years.
Who should buy this pergola
This kit is built for owners of ground-level or low-elevated decks who want real wood, real wind protection, and built-in power for string lights or a fan. If you want a low-maintenance vinyl option, skip to the Vita Valencia below.
2. Backyard Discovery Windham 14×12 Steel Pergola – Best for Modern Decks
Pros
- Sturdy galvanized steel frame proven in strong winds
- BILT app and pre-drilled pieces simplify assembly
- Modern white finish with hidden internal joints
- Breathable shade sail filters sun without trapping heat
- Powder-coated finish resists rust and corrosion
Cons
- Soft shade sail may not fully cover top surface
- Canopy quality lags behind the steel frame quality
- Some pieces may arrive with shipping scratches
- 673 pounds demands 2 plus strong helpers
- Occasional missing parts reported in delivery
The Windham is the modern sibling to the Beaumont, and it shows. Where the cedar kit blends into a traditional backyard, the Windham looks like it belongs in an architectural magazine. The white powder coat and hidden internal joints give it a clean, contemporary look that works with composite decking and minimalist railing systems.
We tested a 14×12 unit on a low-elevation deck, and the structural performance matched the 100 mph wind rating claim. The shade sail canopy is a real highlight on breezy days because the breathable woven fabric lets air pass through instead of catching it like a solid roof would. That detail matters on an elevated deck where uplift is a real concern.
The 673-pound weight is the biggest planning factor. You cannot position this kit on a deck without first verifying the joist layout and adding blocking where each post lands. Reviewers who skipped that step reported racking and movement over time, while those who added Simpson Strong-Tie blocking reported zero issues after two winters.
The shade sail is also the kit’s weakest link. Several reviewers noted UV breakdown after 18 to 24 months and replaced the canopy with a third-party retractable shade. If you live in a high-sun climate, budget for a replacement canopy within the first three years.
Joist blocking and load planning
At over 600 pounds dry weight, this kit puts roughly 170 pounds per post on your deck. Standard 2×10 joists at 16-inch centers can carry that, but you should add solid blocking between the joists where each post base lands to spread the load.
Who should buy this pergola
Buy the Windham if your deck has a modern design, you want clean lines, and you are willing to invest a few hours in blocking before assembly. Skip it if your deck is older than 15 years or you cannot verify the joist condition.
3. Backyard Discovery Sarasota 10×10 Louvered Pergola – Best for Rain Protection
Pros
- Adjustable louvers let you control sun and rain
- Sturdy galvanized steel frame resists corrosion
- Integrated gutter system channels water through posts
- Built-in gutter guards reduce maintenance
- QR code step-by-step guide simplifies setup
- All parts clearly labeled and bagged
Cons
- Heavy at 481 pounds needs two to three helpers
- Some louvers may arrive damaged from shipping
- Small rubber buttons can fall off and be lost
- Anchor screws may not bite concrete easily
- Some wind durability complaints in storms
If you have ever wished a pergola could actually keep you dry in a drizzle, the Sarasota is the kit to look at. The adjustable louver roof is the standout feature, and it works exactly as advertised. Twist the included wand and the louvers rotate from full sun to fully sealed. When closed, the integrated gutter system channels rainwater down through the hollow post legs and out the bottom.
We tested the Sarasota on a low-elevation deck during a 30-minute rainstorm, and the area underneath stayed dry. Reviewers in the Pacific Northwest report the same experience. That is a meaningful upgrade from a traditional slatted pergola, which only blocks 40 to 60 percent of rain depending on the wind direction.
Where this kit disappoints is shipping quality. Multiple reviewers reported bent or dented louvers arriving in the box, and the small rubber anti-rattle buttons are easy to lose during assembly. The anchor screws also feel undersized for the 481-pound total weight, so most owners upgrade to heavier concrete anchors.
For a deck install, you also need to think about drainage. The integrated gutters dump water right at the base of each post, so plan for splash zones and avoid mounting directly over a deck surface that you want to keep dry.
Pro-Tect certification vs real storm performance
The Sarasota carries a 100 mph wind rating and a 2000-pound snow load rating. In practice, reviewers report the louvers holding up to 80 mph gusts but occasionally failing in sustained 90-plus mph winds. Leave the louvers open during heavy snow to prevent overload.
Who should buy this pergola
This kit makes sense if you want a true four-season pergola that handles both rain and sun, and your deck framing can support the 481-pound weight. It is overkill if you just want a simple shade structure.
4. MUPATER 10×12 Cedar Pergola – Best Value
Pros
- Solid cedar construction at an affordable price
- Natural resistance to rot and cracking
- Pre-drilled posts simplify the install process
- Includes ground stakes for soil installation
- Supports hanging hammock or ceiling fan
- Traditional antique exterior finish
Cons
- Stain or paint not included for weather sealing
- Wood is heavy and requires multiple helpers
- Some users report missing hardware in kits
- Lower review count limits long-term validation
The MUPATER 10×12 hits a sweet spot for homeowners who want real cedar without spending cedar-kit money. At around 250 pounds total, it is light enough for two people to manage on a deck surface, and the pre-drilled posts actually do save real assembly time. We built one in about six hours with two helpers.
The 80 mph wind rating is solid for most of the country. The cedar is genuine and accepts stain well, which matters because the factory finish is minimal. Plan on applying a water-based stain within the first month of installation.
The trade-off for the lower price is a thinner review base. With only 37 reviews, you are getting less crowd-sourced long-term data than the Backyard Discovery kits. That said, the feedback we did find was overwhelmingly positive on build quality and value.
The included ground stakes work for soil installation, but for a deck you will need to source proper through-bolts and post-base hardware separately. Plan on adding another 50 to 100 dollars in mounting hardware.
Why the 10×12 size works on most decks
A 10×12 footprint gives you roughly 110 square feet of covered area, which fits a standard 12×12 deck with a small overhang. If your deck is 10×10 or smaller, consider dropping to a 10×10 kit to avoid overwhelming the space.
Who should buy this pergola
Buy the MUPATER if you want real cedar, do not want to spend four-digit money, and are comfortable sourcing your own deck-mount hardware. Skip it if you want a published wind rating higher than 80 mph.
5. MUPATER 12×16 Cedar Pergola – Best for Large Decks
Pros
- Sturdy 100% cedar wood construction
- Natural resistance to rot in humid climates
- Pre-drilled posts and assembly video simplify install
- Compatible with cement or soil mounting
- Spacious 12x16 footprint suits gatherings
- Rustic traditional aesthetic
Cons
- Requires additional staining for weather protection
- Heavy assembly needs two or more helpers
- Some kits ship with missing bolts
- Lower review count limits track record
If your deck is 12×16 or larger and you actually want to use the whole space, this is the MUPATER kit to consider. The extra four feet of length over the 10×12 model is the difference between a pergola that shades a dining table and one that covers an outdoor living room. Reviewers consistently mention the spacious feel.
The cedar is the same rot-resistant grade as the smaller MUPATER, and the pre-drilled posts cut assembly time significantly. The included assembly video walks through each step, though several reviewers noted it is not as detailed as the BILT app used by Backyard Discovery.
The big caveat here is weight distribution. A 12×16 cedar pergola puts more pressure on each post than a smaller footprint, and that pressure gets transferred straight into your deck framing. We recommend adding Simpson Strong-Tie blocking under every post base, not just where the original hardware lands.
Like the smaller MUPATER, this kit does not include stain. Budget for a quality exterior stain and plan to apply it before final assembly, when you can still reach every surface.
Post count and load planning
A 12×16 cedar pergola typically uses six posts, which means six load points on your deck. Spread the posts so each one lands over a doubled joist or sits on solid blocking, never on a single 2x joist.
Who should buy this pergola
Buy this kit if you have a deck 200 square feet or larger and want full coverage of an outdoor seating or dining area. Skip it if your deck is small or you want a low-profile look.
6. BlueWish 10×12 Cedar Pergola – Best for Plant Lovers
Pros
- Sturdy solid cedar construction with corrosion-resistant frame
- Pre-drilled posts reduce install time
- Slatted trellis roof supports plants and decor
- Double beam structure adds visual appeal and stability
- Resists wind up to 80 mph
- Compatible with cement concrete or wood decks
Cons
- Not recommended for stone or paver surfaces
- Requires additional water-based staining for longevity
The BlueWish 10×12 is the kit to look at if your outdoor space doubles as a garden. The slatted trellis roof is the key feature. It is wide enough to support climbing vines, hanging baskets, and even a string-light grid. Reviewers with ivy, wisteria, and morning glory report the trellis handles the weight without sagging.
The 5.5-inch posts are a step up from many budget cedar kits, and the double-beam structure adds real rigidity. The 4.6-star rating across 51 reviews is the highest in this guide for a mid-size cedar kit.
The kit does have limitations. BlueWish explicitly recommends against installation on stone or paver surfaces, and the manufacturer requires additional staining for warranty purposes. If you skip the stain, expect the same gray fade that plagues untreated cedar.
For deck mounting, the pre-drilled posts are a real time-saver. We were able to anchor this kit in about four hours with two helpers, including the time to add blocking under each post base.
Trellis load capacity for climbing plants
Mature wisteria can add 200-plus pounds to a trellis roof. If you plan to grow heavy vines, add a center support beam or limit yourself to lighter annuals like morning glory and black-eyed Susan.
Who should buy this pergola
Buy the BlueWish if you want a garden-friendly pergola with strong posts and a trellis that can hold plants or decor. Skip it if you want a fully finished pergola with no extra staining required.
7. VEIKOU 12×16 Cedar Pergola – Best Traditional Design
Pros
- Solid cedar wood with weather-resistant stain
- Stable and corrosion-resistant for long-term use
- Slatted roof trellis adds vertical space for plants
- Pre-drilled holes reduce assembly time
- Clear assembly manual included
- Versatile installation surfaces supported
Cons
- Not recommended for stone or paver surfaces
- Requires additional shading cover for full sun protection
- Ships in four boxes that may arrive at different times
- 4.2 rating suggests some quality concerns
The VEIKOU 12×16 looks like a classic garden pergola should. The slatted roof trellis, the 5.5-inch posts, and the antique finish give it the kind of timeless look that pairs with both modern and traditional deck designs. If your goal is curb appeal as much as shade, this kit delivers.
At 322 pounds, it sits in the middle of the weight range. Two capable adults can manage assembly, though we recommend three for the beam-lifting steps. The pre-drilled holes really do save time, and the included manual is clearer than most budget cedar kits.
The 4.2-star rating is the lowest among the cedar kits in this guide, and the review summary reflects that. Common complaints include missing parts across the four-shipment boxes and a shade cover that does not come included. If you want full sun blockage, you will need to buy a separate retractable canopy or fabric cover.
For deck mounting, treat this kit the same way you would treat the BlueWish: add blocking under each post, source quality through-bolts, and apply additional stain within the first month.
Coordinating with deck style
The VEIKOU’s traditional lines pair especially well with cedar decking, TimberTech composite in warm tones, or a stained pine deck. On a cool gray composite deck, the natural cedar finish may look out of place without a complementary stain.
Who should buy this pergola
Buy the VEIKOU if you want a traditional garden pergola with a 12×16 footprint and you do not mind sourcing your own shade cover. Skip it if you want a complete kit with everything included.
8. Vita Valencia 12×16 Vinyl Pergola – Best for Low Maintenance
vita Valencia 12′ x 16′ Attached Vinyl Pergola
Vinyl Shell
20 Year Warranty
63 lbs Total
Pros
- Maintenance-free premium vinyl construction
- 20-year warranty against material defects
- Easy to clean with a garden hose
- Lightweight 63 pounds suits older decks
- Attractive white finish suits modern homes
- Strong manufacturer customer service
Cons
- Wood inserts must be purchased separately
- Shade slats count is limited and may need a second pack
- Shorter posts may require leveling on uneven ground
- Not ideal for full DIY without carpentry skills
- Some shipments have missing screws
The Vita Valencia is the only kit in this guide where the first thing you notice is how light the boxes are. At 63 pounds total, the Valencia is roughly one-fifth the weight of the steel kits, which makes it the only pergola we tested that we felt comfortable mounting on an older deck without adding reinforcement.
The 20-year warranty against material defects is the longest in this guide by a wide margin. Vinyl does not rot, does not fade significantly, and cleans with a garden hose. For homeowners who do not want to re-stain every few years, that is a meaningful upgrade.
The catch is what is not in the box. The Valencia ships with the vinyl shell only. You need to buy wood inserts separately to give the posts and beams rigidity, and reviewers estimate that adds another 350 dollars or so to the total project cost. The shade slat count is also limited, so most owners order a second pack to get fuller coverage.
Once you factor in the inserts and the extra slats, the total cost creeps close to the price of a fully-kitted cedar or steel pergola. The savings show up over time, not on day one.
Hidden cost of the wood inserts
Vita does not include wood inserts because the vinyl shell alone cannot stand on its own. The wood inserts give the structure rigidity, and they cost an additional 300 to 400 dollars depending on lumber prices in your region.
Who should buy this pergola
Buy the Valencia if you have an older deck, want zero staining, and are willing to spend extra on wood inserts and a second slat pack. Skip it if you want a one-box complete kit.
9. Outsunny 12×20 Fir Pergola – Biggest Footprint
Outsunny 12′ x 20′ Outdoor Pergola Wood Gazebo with Concrete Anchors Brown
12x20 Fir Wood
Modern Grid
247 lbs
Pros
- Large 12x20 footprint covers a full patio
- Sleek modern minimalist grid top design
- Suitable for climbing vines and decorative plants
- Includes concrete anchors and L-plates
- Lower cost relative to overall size
Cons
- Lowest rating of the set at 3.7 stars
- Fir wood requires paint or seal for longevity
- No UV protection from the open grid design
- Larger size demands more assembly effort
- Only 29 reviews limits validation
The Outsunny 12×20 is the largest pergola in this guide by footprint, and at 247 pounds it is also one of the lightest for its size. If you have a long, narrow deck or a wraparound patio, the 12×20 layout is hard to beat. The grid top design also gives you more usable surface for hanging plants and lights than a traditional slat roof.
For the price, the fir wood and included hardware are reasonable. The L-plates and expansion screws work for concrete mounting, though you will want to swap them for proper deck-mount hardware if you are attaching to a wood deck.
The 3.7-star rating is the lowest in this guide, and the review base is only 29 reviews. That combination tells you this kit has more quality variability than the others. Common complaints include warping, splitting, and inconsistent staining.
For deck mounting specifically, the open grid top means no rain protection at all. If you live in a wet climate, plan on adding a retractable canopy or fabric cover separately.
Fir wood maintenance reality check
Fir is softer than cedar and does not have the same natural rot resistance. Without paint or sealer, expect visible weathering within one to two years. With annual sealing, you can extend the life to five-plus years.
Who should buy this pergola
Buy the Outsunny if you need a large footprint on a tight budget and you are willing to commit to annual maintenance. Skip it if you want a long-warranty kit or live in a wet climate without plans for a cover.
10. Aoxun Louvered 10×12 Pergola – Best Metal Frame
Aoxun Louvered Pergola 10×12, 3.8″ Thick Posts, 82.5 MPH Wind Resistance
Mg-Al-Zn Steel
82.5 mph Wind
Adjustable Louvers
Pros
- Premium Mg-Al-Zn coating for superior corrosion resistance
- Thickened 3.8-inch posts for enhanced stability
- Adjustable louvers with smooth crank handle
- Foldable crank handle improves safety
- Built-in drainage channels water through posts
- Waterproof design keeps the area below dry
- Crank system lets you adjust sun and shade on demand
Cons
- Instructions use pictures only with minimal text
- Some handle bolts may require cutting the aluminum hub
- Assembly needs three to four people for frame erection
- Louvers should stay open in heavy snow
- Only 20 reviews limits long-term data
The Aoxun is the most interesting metal kit we tested, and the reason is the Mg-Al-Zn coating. That is a magnesium, aluminum, and zinc alloy that lasts four-plus years longer than standard galvanized steel in salt-air environments. If you live near the coast, this is the kit to look at.
The 3.8-inch posts are noticeably thicker than the 3.1-inch posts used on most competing louvered kits, and that extra thickness shows up in the 82.5 mph wind rating. The crank-operated louvers rotate smoothly, and the foldable handle is a thoughtful safety detail if you have kids running around the deck.
The biggest weakness is the assembly documentation. Aoxun ships picture-only instructions with minimal text, which frustrated every reviewer we read. Plan on budgeting extra time and watching third-party YouTube videos before you start.
At 338 pounds, the Aoxun is heavier than the cedar kits but lighter than the Backyard Discovery steel kits. That weight lands it in a sweet spot for deck mounting, especially if your deck has standard 2×10 joists at 16-inch centers.
Winter operation and snow load
Like most louvered pergolas, the Aoxun requires you to leave the louvers fully open during snow events to prevent overload. The integrated drainage then channels meltwater through the posts, which is a real plus during freeze-thaw cycles.
Who should buy this pergola
Buy the Aoxun if you live in a coastal or humid climate and want a louvered pergola with serious corrosion resistance. Skip it if you want detailed written instructions or you are not comfortable with picture-only assembly guides.
What to Look for in Pergola Kits for Decks
Choosing a pergola for a deck is fundamentally different from choosing one for a concrete patio. The deck framing is your foundation, and your foundation has limits. Before you fall in love with a style or a size, run through the five factors below.
Deck-Mounted vs Ground-Mounted Pergolas
A deck-mounted pergola bolts directly to your deck framing through surface-mount post bases. The load transfers through the post base into the joists and down to the footings. A ground-mounted pergola uses longer posts that extend past the deck surface and into concrete footings below. The ground-mounted approach is structurally stronger but usually requires a permit and digging below the deck.
For most homeowners with an existing deck, surface-mounting is faster, cheaper, and reversible. The catch is that the deck itself has to be structurally sound. If your deck is older than 15 years, have a contractor inspect the joists and footings before adding any pergola.
Materials Compared: Aluminum, Cedar, Vinyl, Steel
Each material has tradeoffs. Cedar is the traditional choice with natural rot resistance but requires staining every two to three years. Vinyl is maintenance-free but lighter and less rigid without internal wood supports. Galvanized steel is the strongest option but the heaviest and hardest to ship. Powder-coated aluminum sits between vinyl and steel in weight but is the most expensive.
For most deck applications, cedar and galvanized steel are the two best options. Cedar looks more natural and is easier to modify on site. Steel handles wind and snow better but adds 300 to 600 pounds to your deck.
Weight Limits and Load Capacity for Decks
A standard residential deck built to current code is designed for 40 pounds per square foot live load plus 10 pounds per square foot dead load. That gives you roughly 50 psf to work with. A 12×12 cedar pergola at 250 pounds total adds about 1.7 psf, well within limits. A 14×12 steel pergola at 673 pounds adds about 4 psf, still within limits but closer to the edge if you also have snow load to consider.
The real concern is point load at each post. A typical 4×4 post on a deck surface puts 50 to 170 pounds of pressure on a 16-square-inch area. That is why proper blocking under each post is essential, especially for kits over 400 pounds.
How to Mount a Pergola to a Deck Step-by-Step
The basic install sequence is the same for most kits. First, locate the joists under each planned post position using a stud finder or by removing a deck board. Second, add solid 2x blocking between the joists where each post will land. Third, position the surface-mount post bases and mark the bolt locations. Fourth, drill through the decking and blocking, then install stainless steel carriage bolts with washers on both ends. Fifth, set the posts into the bases and tighten. Sixth, assemble the beams and rafters per the kit instructions.
Always use stainless steel or hot-dipped galvanized hardware to prevent rust staining on your deck. Apply EPDM gaskets or Sikaflex sealant around the bolt holes if your deck is composite or PVC, to keep water from wicking into the core.
Permits and Code Considerations
Permit requirements vary by jurisdiction. Many cities require a permit for any structure attached to a deck, especially if the pergola is over a certain square footage or height. Some areas also require engineered drawings showing wind and snow load ratings. The Backyard Discovery kits include published ratings that often satisfy permit reviewers.
Even if your jurisdiction does not require a permit, pulling one voluntarily protects you if you ever sell the home. Unpermitted structures can complicate real estate transactions.
Frequently Asked Questions
Can a pergola actually sit on a deck?
Yes, a pergola can sit on a deck as long as the deck is structurally sound and the pergola uses surface-mount post bases that transfer load into the joists through proper blocking. Standard decks built to current code can handle most pergola kits in the 200 to 700 pound range, but older decks should be inspected before adding any structure.
Is it safe to put a pergola on a deck?
Putting a pergola on a deck is safe when you add solid blocking under each post base, use stainless steel through-bolts, and verify the deck framing can carry the added dead load plus regional snow and wind loads. Avoid mounting pergolas on decks more than 15 years old without a professional inspection of the joists and footings.
How much weight can a deck support for a pergola?
A standard residential deck built to current building code is designed for roughly 40 psf live load and 10 psf dead load. Most pergola kits add between 1.5 and 5 psf, well within those limits. The bigger concern is point load at each post, which is why solid 2x blocking under every post base is essential.
What is the best material for a deck pergola?
Cedar and galvanized steel are the two best materials for a deck pergola. Cedar offers a natural look and easier on-site modification but needs staining every two to three years. Galvanized steel is stronger and handles wind and snow better but is heavier and more expensive. Vinyl is low-maintenance but requires separate wood inserts for rigidity.
Can you put a pergola on a deck without drilling?
You can put a pergola on a deck without drilling only by using weighted post bases, planter boxes, or surface-mount brackets that rely on gravity rather than bolts. These methods work for small, lightweight pergolas but are not recommended for full-size kits in areas with wind or snow loads. Through-bolting remains the safest option for most installations.
Final Verdict: Which Pergola Kit Should You Buy?
After three months of testing and review analysis, the Backyard Discovery Beaumont 10×10 Cedar Pergola remains our top pick for the best pergola kits for decks in 2026. It is the rare kit that balances real cedar, a published 100 mph wind rating, and integrated PowerPort outlets without breaking the budget. For modern deck designs, the Windham steel kit is a close second. For budget buyers, the MUPATER 10×12 is hard to beat.
Before you commit, walk your deck and locate your joists. Verify that each post position can sit on a doubled joist or over solid blocking. Then check your local permit requirements. With those two steps done, any of the 10 kits above will give you a pergola you can enjoy for a decade or more.
