When you don’t need a permit
Freestanding decks not exceeding 30 inches above grade are generally exempt from building permits per the California Building Code as adopted locally. No structural attachment to the dwelling means simplified requirements.
When you do need a permit
Attached decks require a building permit regardless of height because they involve structural connections to the dwelling. Plan review and inspection are required to verify proper ledger board attachment and structural adequacy.
Any deck more than 30 inches above grade requires a building permit per CBC §105.2. Elevated decks require engineered footings, guardrails (minimum 42 inches in California), and structural plan review.
Covered decks (with a roof structure) always require a building permit as they constitute a new structure. The roof/cover component adds structural and potentially drainage requirements that must be reviewed.
