Planning to build a patio in your backyard? Before you pour concrete or add a cover, it’s crucial to know your local permitting rules. What happens if you build a patio without a permit? Can you get in trouble or be forced to tear it down later?
This guide breaks down exactly when you need a permit, what projects require approval in California, and the real risks of skipping the process—whether you’re building a concrete slab, gazebo, or covered patio.
California-Specific Patio Permit Requirements
California has stricter patio permit requirements than many other states, thanks to detailed building codes and zoning laws. Whether you’re in Sacramento, Los Angeles, or a smaller city, knowing what’s required can save you from serious headaches later.
When Do You Need a Permit for a Patio in California?
In general, you’ll need a permit if your patio includes:
- A covered patio or patio cover (attached or detached)
- A concrete slab larger than 200 square feet
- Raised patios or decks more than 30 inches off the ground
- Electrical or plumbing work, such as lighting, fans, outlets, or gas lines
- Permanent structures like gazebos, pergolas, or sunrooms
Projects That Usually Don’t Require a Permit in California
You may be able to skip the permit if the patio:
- Is uncovered and built at ground level (less than 30 inches high)
- Is under 200 square feet
- Uses portable or non-permanent materials, such as shade sails or prefab gazebos
- Has no electrical or plumbing hookups
⚠️ Always double-check with your local building department—some areas (like San Francisco or Pasadena) have more restrictive codes.
Additional Local Considerations
- HOA Approval: Most subdivisions or communities with HOAs require pre-approval
- Zoning Rules: These can affect your setback requirements (distance from property lines)
- Environmental Regulations: May apply in wildfire zones, floodplains, or along the coast
