How Do You Research Building Permits?
By JC Pacific Corp Published 2026-09-01 Last professionally reviewed: September 2026
Start with the city or county building department responsible for the property. Search by address and parcel number, then review the permit description, status, plans, inspections, corrections, and final approval.
What information should you request?
Look for:
- Permit number
- Application date
- Scope of work
- Contractor
- Valuation
- Approved plans
- Inspection history
- Correction notices
- Final inspection
- Certificate of occupancy
- Open or expired permits
- Code violations
- Planning approvals
- Solar and battery permits
What if no records appear online?
Older records may be stored on microfilm, paper, or in a different department. Submit a public-records request or contact:
- Building department
- Planning department
- Code enforcement
- Fire department
- Public works
- County assessor
- Health department
Does a permit prove the current structure matches the plans?
No. Compare records with the property and use appropriate inspectors or professionals.
If online records are incomplete, California's Public Records Act supports requests for public records from local agencies.
Frequently Asked Questions
Does issued mean the permit was finalized?
No. Look for final inspection or completed status.
What does an expired permit mean?
The work may be unfinished, uninspected, abandoned, or completed without final approval.
Can permit records contain errors?
