Deck Permit rules nationwide, beyond California.

Framing a backyard deck: fresh lumber and a nail gun on new decking

Requirements and size thresholds for deck permits vary by locality. The table below compares what each California county or city requires. Always confirm with the local office before starting.

Comparing states? See deck permit rules across every locality we cover.

The application steps and inspection sequence for deck permits come from the model code rather than from California law, so they read the same wherever you build. We keep that walkthrough in one place: how a deck permit application and its inspections work, start to finish. What changes between California jurisdictions is below: who requires a permit, what they charge, and which office you file with.

What a deck permit costs in California

13 California jurisdictions we cover publish a fee figure for this work. Each line is quoted from that office's own schedule and linked to its citation. The figures are not comparable to one another: some are flat minimums, some a percentage of job value, some charged per fixture, so what you pay depends on which schedule applies and on your job's valuation.

Alameda County

No deck line item appears in the Building Inspection Department Service Fee Schedule (Schedule A, effective July 1, 2024). A deck permit is priced from construction valuation using the Schedule A building permit fee table (for example, '$381.46 for the first $10,000 plus $8.88 for each additional $1,000.00 or fraction thereof, to and including $50,000'), plus building plan review at 80% of the building permit fee with a $140.00 minimum, plus a $20.00 single-permit processing fee.

Common questions about deck permits in California

Do I need a deck permit in California?
In California it depends on the size of the job. Permits are issued locally, so the answer comes from your California city or county rather than a single statewide rule. Of the 14 California jurisdictions we have verified for deck work, 3 require a permit outright, 11 depend on the size or scope of the job, and 0 require none.
Is there a deck permit exemption in California?
11 of the 14 California jurisdictions we cover set a threshold rather than a flat rule, so the same job can be exempt in one California county and permitted in the next. The table above lists each California jurisdiction's published threshold in its own words, with the source and the date we verified it.
