Summary

Santa Rosa requires a permit for any work regulated by the currently adopted California Codes, Title 24, before construction begins. The Building and Code Compliance Division, under the Building Official, issues building, plumbing, mechanical and electrical permits together on a single combined form based on the cumulative value of the work.

Any person desiring to perform work regulated by currently adopted editions of the California Codes, Title 24, or any laws, amendments, ordinances or other regulations administered by the Building and Code Compliance Division, or that may be adopted and administered in the future, shall secure permits and pay fees as set forth in this chapter.

Violations & Fines

Starting work without the required permit triggers a mandatory special investigation before any permit can issue, plus an investigation fee equal to the full permit fee, on top of the permit fee itself (Section 18-08.170). Paying the investigation fee does not excuse compliance with the code or shield the violator from any other penalty. Emergency work is exempt from the investigation-fee rule only if the applicant proves to the Building Official's satisfaction that the work was urgently necessary and getting a permit first was impractical (Section 18-08.180). General violations of Title 18 are subject to the penalty provisions of Section 1-28.010.

Frequently Asked Questions

When does Santa Rosa require a building permit?
Whenever the work is regulated by the currently adopted California Codes, Title 24, or by a related City regulation, per Section 18-08.010. The Building Official sets project valuation from the total cost of construction, finish work and permanent equipment, and that valuation sets the permit and plan review fees.
Can one permit cover building, electrical and plumbing work on the same project?
Yes. Section 18-08.020 has the Department of Planning and Economic Development issue building, grading, plumbing, mechanical and electrical permits on a single form, with the fee calculated on the cumulative value of all the combined work.
How long is a Santa Rosa building permit valid once issued?
365 days from issuance to start work, per Section 18-08.060. If work is suspended or abandoned for 365 days after starting, the permit also becomes invalid. The Building Official can grant a 180-day extension, and a further 180 days if work is diligently underway, but not if no work or inspection has occurred within three years of issuance.
What happens if I start construction without a permit in Santa Rosa?
Section 18-08.170 requires a special investigation before the City will issue the permit, and adds an investigation fee equal to the full permit fee on top of the permit fee owed. That payment does not excuse the underlying violation or block other penalties the City may pursue.
