How do I apply for a permit in San Luis Obispo?

The city’s online portal lets you apply for a building permit, view permits, pay invoices and view public records. The city notes that new users must register, and the verification email comes from Community Access Identity. Staff review plans to confirm the design meets city and state construction codes, and certified inspectors check that work matches the approved plans.

ADU legalization

Homeowners with an ADU built before 2020 may use the city’s ADU Amnesty process, covered in our San Luis Obispo zoning and ADU guide.

How permits affect selling a house in San Luis Obispo

How San Luis Obispo permit applications work

The city says the property owner is responsible for getting a building permit from the Building & Safety Division before a building is built or altered.

You register for an account on the city’s online portal, then use the Apply button or the application assistant to submit forms and apply.

Staff review the plans to confirm the design meets city and state construction codes, and once a permit is issued, certified inspectors check the work against the building code and the approved plans. You can also schedule inspections, view permits and pay invoices on the portal. Fire and demolition inspections must still be scheduled by phone at (805) 781-7180.

Contacts, hours and fees

The city lists Building and Safety at (805) 781-7180 and the division email as building@slocity.org. Community Development walk-in hours moved to Monday through Thursday, 9 a.m. to noon, beginning April 13, 2026. The city also posted a notice that its email system was recently down and replies may take longer.

Fees are in the city’s Comprehensive Fee Schedule, and the city lists a Building Permit Services Supervisor you can call for fee estimates.

If you are selling a house with an unfinished permit, ask which inspections remain and what they cost before you decide whether to finish the work or sell as it is.

California disclosure rules when permits are in question

Permit rules are local, but disclosure rules are statewide. Under Civil Code section 1102.1, delivery of the transfer disclosure statement cannot be waived in an as-is sale, and your duty to disclose material facts affecting value or desirability stays in place.

If you know of work done without a required permit, treat it as a material fact and raise it with your agent or escrow officer. Our California as-is and unpermitted work guide explains what as-is changes and what it does not.
