Full Breakdown
Under San Jose Municipal Code § 24.02.100, no building, structure, or building service equipment regulated by Title 24 and the technical codes may be erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted, or demolished unless a separate permit for each item has first been obtained from the building official. Section 24.02.120 carves out narrow exemptions, small detached accessory buildings under 120 sq ft, fences up to 7 feet, retaining walls under 4 feet, small water tanks, minor decks, and similar low-risk work, but separate plumbing, electrical, and mechanical permits still apply to those exempted items. Permits are issued by the Building Division after plan review under § 24.02.310, and an issued permit expires if work doesn't start within 12 months or is abandoned for 180 days per § 24.02.340.
Violations & Fines
Working without a required permit exposes the owner to permit suspension or revocation under § 24.02.360, investigation fees for unpermitted work under § 24.02.440, and required correction of any resulting code violations before the work can be legalized.
