What Fremont Building & Safety actually reviews.
Fremont Building & Safety runs plan check on every garage conversion project at this scope. Full plan-check cycle (2–3 rounds of corrections is typical) — expect 6–14 weeks from submittal to issued permit. Hillside-overlay parcels need grading-quantity and haul-route sign-off.
Fremont follows California's ministerial ADU pathway (Gov. Code §§ 65852.2 / 65852.22). Fremont Building & Safety cannot deny a code-compliant ADU on a single-family lot and must respond within 60 days. Local ADU ordinance language may add design-review for exterior changes but cannot override the state minimums.
Estimated review timeline: 8–17 weeks to issued permit, including 1 overlay review plus Fremont Building & Safety plan check.
