Deck Construction Permits in San Jose
Local Rule
City of San Jose Community Development Department
San Jose exempts a freestanding deck of 200 square feet or less that stays 30 inches or less above adjacent grade at every point; there is no square footage exemption for an attached deck at all, since any deck connected to the main structure needs a permit regardless of size. San Jose sits in Seismic Design Category D under the California Building Code, so every permitted deck must meet CBC seismic lateral-force requirements, including hold-down hardware at ledger connections and footing design engineered or built to prescriptive SDC D standards. The city's own fee structure is real and stacked: a $227 base permit issuance fee, plus a $325 base plan review fee, plus a $367 base inspection fee, rising with project valuation.

How This Compares to Santa Clara County
San Jose's own rule is shown above (Depends on project scope). Here is the separate rule that applies at the county level, for context:
Santa Clara County, CA (WUI / Chapter 7A)
A permit is required to build or replace a deck in Santa Clara County when it is attached to the house, more than 30 inches above grade, or over about 200 sq ft; a small freestanding deck may be exempt. In the county's CAL FIRE-mapped Fire Hazard Severity Zones (the Wildland-Urban Interface), the deck's walking surface and framing near the home must use ignition-resistant, noncombustible, or fire-retardant-treated materials (California WUI Code, formerly CBC Chapter 7A).
