Planning a construction or renovation project in California? You’ll likely need a building permit before you begin. In this guide, we explain how to get a building permit in California, how long it usually takes, and how to avoid the most common delays.
When Do You Need a Building Permit?
In California, you typically need a permit for:
- Room additions or new structures
- Garage or basement conversions
- Structural changes (e.g., removing load-bearing walls)
- Major electrical, HVAC, or plumbing upgrades
You usually don’t need a permit for:
- Painting, flooring, or cabinetry
- Replacing fixtures without moving pipes or wires
Always check with your local building department — rules vary by city and county.
How to Get a Building Permit in California
Follow these steps to get your permit approved:
1. Prepare Construction Plans
Create detailed drawings that include:
- Site plan
- Floor plan
- Elevations
- Structural details (if needed)
Plans must follow the California Building Code and your city’s local zoning rules.
2. Submit Application
Apply online or in person through your local city or county permit portal. You’ll need:
- Completed permit form
- Drawings
- Engineer or architect stamp (for structural work)
- Contractor info or owner-builder declaration
3. Plan Review
City officials will review your plans. If changes are required, you’ll receive correction notices.
4. Pay Fees
Permit fees vary depending on project size and location. Residential remodels may range from $200 to $2,000+.
5. Receive Your Permit
Once approved, you’ll get the permit and can begin work. You must post the permit visibly on-site.
6. Schedule Inspections
City inspectors will visit during and after construction. Final approval is required to close the permit.
