Do You Need a Permit for a Patio Cover?
In most jurisdictions, yes. A patio cover is a structure, and structures typically require building permits. But the rules vary significantly by location, and some types of shade structures may be exempt.
What Usually Requires a Permit
- Any structure attached to the house (this includes attached pergolas, patio covers, and permanently mounted awnings)
- Freestanding structures over a certain size (often 120-200 square feet, depending on your jurisdiction)
- Any structure that includes electrical wiring
- Structures that modify the existing roofline or drainage
What Might Be Exempt
- Small freestanding structures under your local size threshold (check your county or city code)
- Temporary or removable structures like shade sails, patio umbrellas, and pop-up canopies
- Retractable awnings (some jurisdictions exempt these because they're considered removable, but check yours)
How to Check
Call or visit your local building department (city or county level). They can tell you whether your specific project requires a permit and what the application process looks like. Many building departments have this information on their websites. You can also search for your jurisdiction on your state's government website.
What Happens If You Build Without a Permit
Building without a required permit can result in fines, a stop-work order, or being required to tear down the structure. More practically, an unpermitted structure can create problems when you sell your home — home inspectors flag unpermitted additions, and buyers may require you to obtain retroactive permits or remove the structure as a condition of sale. It can also void your homeowner's insurance coverage for anything related to the structure.
The Permit Process
For a typical patio cover, the process involves submitting a plan drawing (showing dimensions, materials, attachment method, and setbacks from property lines), paying a permit fee ($50-$500), and having the completed work inspected by a building inspector. Some jurisdictions also require engineered plans stamped by a licensed engineer, especially in areas with high wind or snow loads. The whole process typically takes 2-6 weeks.
