ADUs · Know About Them
Every city writes its own ADU playbook, setbacks, height limits, parking, fee schedules. DWELLTRY has simplified its service area to 14 municipalities we know cold, so your project moves from concept to permit without the guesswork. Pick a city to see its specific rules.

Coronado, Carlsbad, Oceanside, Encinitas, Solana Beach, and parts of San Diego sit in the Coastal Zone. That adds a Coastal Development Permit, 2–4 extra months.
Oceanside and Chula Vista clear ADUs in 3–4 months. Escondido and Poway lean closer to 6–8. Knowing this up front lets you sequence your move-in or rental income realistically.
Poway = fire zone (Chapter 7A). La Mesa & Coronado = historic review. County = septic + biology. We model these into your feasibility before you spend a dollar on design.
