What Encinitas Development Services actually reviews.
Encinitas Development Services runs plan check on every detached adu project at this scope. Full plan-check cycle (2–3 rounds of corrections is typical) — expect 6–14 weeks from submittal to issued permit. Coastal Zone parcels add CDP review through the CA Coastal Commission or local LCP.
Encinitas follows California's ministerial ADU pathway (Gov. Code §§ 65852.2 / 65852.22). Encinitas Development Services 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 Encinitas Development Services plan check.
