FAQs
Common Questions About ADUs
What are ADUS?
Accessory dwelling units (ADUs) are secondary housing units on single-family lots, such as backyard cottages or garage apartments, providing independent living facilities, increasing housing options, supporting multigenerational living, and adding flexible, often affordable housing capacity.
Are ADUs legal in my area?
ADU legality depends on your city and state. Check your municipal zoning code, state ADU laws, and planning department for setbacks, parking, size, and permits. Confirm with official portals or a local planner before proceeding.
How much does it cost to build an ADU?
In the U.S., building an ADU typically costs $150,000–$400,000+ ($250–$600 per sq ft), depending on size, type, site work, utility upgrades, permits, and finishes; garage conversions often range from $80,000 to $200,000.
Can I rent out my ADU?
Yes, often—but it depends on local zoning and permitting. Confirm owner‑occupancy rules, minimum lease lengths, short‑term rental bans, parking and utility requirements, safety codes, HOA/CC&Rs, and insurance and tax implications before advertising or signing leases.
How long does it take to build an ADU?
Building an ADU typically takes 6–12 months, including 2–4 months for design and permitting and 3–6 months for construction. Timelines vary by jurisdiction, project complexity, financing, utilities, and whether site-built or prefabricated modules are used.
