Best Pergola and Gazebo Kits, Compared on What Your Permit Will Need

Open slat, louvered and hardtop kits compared on the paperwork a permit office asks about: outside dimensions, wind and snow figures, anchoring instructions and the maker's assembly manual.

As an Amazon Associate, PermitRoadmap earns from qualifying purchases. It does not change the permit information on this site.

Whether a pergola or gazebo kit needs a permit depends on where you live, how big it is, what kind of roof it has and whether it is attached to the house. The model residential code most states start from, the 2021 IRC, exempts a one-story detached accessory structure of up to 200 square feet from a building permit. Many places change that limit or review a roofed patio cover differently, and setbacks still apply when no building permit is needed.

Key takeaways

  • Check the rule for your address before you order. For a roofed cover attached to the house, check the patio cover rule instead.
  • Go by the kit's published outside dimensions, not the "12 x 12" in its name.
  • An open slat roof, a louvered roof and a solid hardtop can land in different categories in your local code.
  • A maker's wind figure counts only if you anchor the posts the way its manual says.

How we compare pergola and gazebo kits

We did not test these kits. We read each maker's product pages, assembly manuals and warranty terms, noted where a maker publishes two different numbers, and checked that each Amazon listing is sold by Amazon or the maker. The wind and snow figures are the makers' own claims. None of these makers publishes stamped or engineer-sealed plans for its kits.

Our picks

  1. 1Best open pergola

    Backyard Discovery Beaumont 12 x 10 Cedar Pergola

    Model 6214B

    Permit paperwork: Mostly complete

    An open cedar slat pergola with a published wind figure, exact outside dimensions and a manual that says how many anchors go in each post. With no roof covering, it is the simplest of these kits to explain to a permit office.

    Why we picked it: No roof covering, a 100 mph wind figure tied to the manual's anchoring, and a manual that calls for four anchors in each post.

    Model Alexander 12 x 12

    Permit paperwork: Mostly complete

    An aluminum frame gazebo with a steel double roof and a manual with a real anchor blueprint. Kozyard's wind figure is lower than the others here, the manual sets a lower limit for the sidewalls, and the warranty does not cover wind or snow damage.

Open, louvered or solid roof

The kits here come with three kinds of roof. An open slat roof, like the Beaumont, has no covering. A louvered roof, like the Sarasota, has steel blades that close to shed rain. A hardtop, like the Barrington, Norwood, Kozyard and Yardistry, has a solid steel or aluminum roof.

Local codes draw the line in different places. Some offices treat an open pergola as an accessory structure and a solid or louvered top as a patio cover with its own review. Escondido, California, for example, requires a design and plan check for a solid roof patio cover built any other way than its handout shows. Ask your office which category your kit falls into before you buy.

The 200 square foot line, and what it leaves out

Section R105.2 of the 2021 IRC exempts one-story detached accessory structures of up to 200 square feet of floor area from a building permit. It covers detached structures only, so a cover attached to the house is outside it. The same section says the exemption does not allow work that breaks other local laws, so setbacks and height limits still apply, and so can HOA rules. Many places adopt a lower limit.

By the makers' published sizes, every kit here is under 200 square feet, from about 115 square feet for the Sarasota to about 170 for the Yardistry 12 x 14. A place with a smaller limit, or one that counts the full roof area, can still put the same kit over the line. Wiring in lights, a fan or outlets is electrical work, which the 200 square foot exemption does not cover.

Wind and snow figures depend on anchoring

Your building department sets the design wind speed and ground snow load for your area in the IRC's climate table, R301.2(1). One Maryland county, for example, lists 120 mph and a 20 pound per square foot ground snow load. You can look up your address in ASCE's free Hazard Tool, then ask the building department which edition and risk category it uses.

  • Backyard Discovery's 100 mph figure applies only when the kit is anchored as its manual specifies.
  • Kozyard says 60 mph "when properly anchored" on its product page, but its manual says to open or remove sidewalls and netting in winds over 30 mph. Plan with the lower number.
  • The Sarasota manual says to turn the louvers fully open when high wind, ice or snow is expected.
  • Makers state snow as roof weight or depth, such as 7,500 pounds or 30 inches for the Barrington and 2,500 pounds for the Kozyard. That is not the same as your area's ground snow load, so ask your office how it wants roof snow load shown.
  • Yardistry publishes no wind or snow number and says accumulated snow must be removed from the roof.

Anchoring and warranty terms

Backyard Discovery includes concrete anchors but says hardware for a wood deck is not included and the deck needs ample structural support under it. It recommends a concrete surface or concrete post pads. Kozyard strongly recommends anchoring into concrete, with 3/8 x 3 inch sleeve anchors (not included) in concrete over 3 inches deep, and only after assembly is finished. Yardistry supplies post mounts but no anchoring hardware, and tells you to check local building codes for acceptable installation. Where the ground freezes, local frost depth can call for deeper footings than a kit drawing shows.

Warranties do not cover storms. Backyard Discovery's warranty is void if the kit is not installed per its assembly instructions, and it excludes wind and storms as acts of nature. Kozyard's warranty excludes damage from wind and snowstorms, and Yardistry's excludes acts of nature including wind. A wind figure is not a promise to pay for storm damage.

What to hand your installer or building department

Send the maker's assembly manual, the product page showing outside dimensions and any wind and snow figures, and the anchoring layout or footing drawing. Add a simple site plan with distances to property lines and the house. Since none of these makers publishes stamped plans, an office in a high wind or heavy snow area may ask for an engineer's letter, so ask before you order.

Also considered

Products we looked at and left out, as of Oct 5, 2026. No links, because we would not recommend buying them through us.

  • Sunjoy 12 x 12 hardtop gazebos

    The product page says 50 mph, but the manual says the gazebo is for decorative and shade purposes only and is not designed for high winds, rain or snow. The Amazon listings we found were not sold by Sunjoy or Amazon.

  • Erommy 12 x 16 hardtop gazebo

    The maker rates it for 44 mph and under 3 inches of snow, and lists only ground stakes for anchoring.

  • Mirador pergolas

    Mirador's own pages publish conflicting wind and snow ratings for the same models, and we found no test document.

  • Purple Leaf hardtop gazebos

    We could not find a public assembly manual on the maker's site.

  • Domi pergolas

    We could not tie the Amazon seller to the maker.

  • Mondawe hardtop gazebos

    The maker gives wind as a force number rather than a speed, and we found no manual online.

Frequently asked questions

Does a pergola need a permit?
It depends on where you live. The 2021 IRC exempts detached one-story accessory structures up to 200 square feet, but many places set a lower limit or treat a solid or louvered roof as a patio cover. Check the rule for your address.
Does a hardtop gazebo need a permit?
Often, if it is permanent or over the local size limit. The makers say so themselves: Backyard Discovery and Yardistry both warn that permanent structures may require a building permit and tell you to check with your local planning, zoning and building departments.
What wind rating does my pergola or gazebo need?
Whatever your building department uses for your area, which comes from its climate table or the ASCE wind maps. A maker's figure, such as Backyard Discovery's 100 mph, only applies when the kit is anchored as its manual specifies.
Can I put a gazebo or pergola on a wood deck?
Some makers show how, but check the deck first. Backyard Discovery says deck hardware is not included and the deck needs ample structural support under it, and Yardistry shows a deck example with anchoring hardware sold separately. Ask your inspector what your deck needs.
Did you test these kits?
No. We compared what each maker publishes in its product pages, manuals and warranty terms, and checked that each Amazon listing is sold by Amazon or the maker. Our ratings describe the paperwork, not performance.
Why are the prices not listed?
Prices change often, so the buttons take you to Amazon for the current price. PermitRoadmap earns a commission on qualifying purchases, which does not change our ratings or the permit information.
