Does Palo Alto require a permit?

What Palo Alto Planning & Development actually reviews.

Palo Alto Planning & Development runs plan check on every seismic retrofit project at this scope. Full plan-check cycle (2–3 rounds of corrections is typical) — expect 6–14 weeks from submittal to issued permit. Historic-overlay parcels need design review before plan check accepts the package.

Palo Alto pre-1980 cripple-wall and soft-story buildings qualify for the standard plan set (CEA Brace+Bolt / FEMA P-1100). Permits issue over-the-counter when the engineer-of-record signs the standard set — no full plan check required.

Estimated review timeline: 8–17 weeks to issued permit, including 1 overlay review plus Palo Alto Planning & Development plan check.
