FAQs

ADU Construction FAQ — Niagara County, NY

ADU construction costs vary enormously: detached ADU (new construction): $150,000–$350,000+. Garage conversion: $80,000–$150,000. JADU (junior ADU within existing home): $40,000–$100,000. Costs are heavily dependent on your local construction market, whether utilities need to be extended, and finish quality. Get 3 quotes with the same scope and permit strategy outlined.

You need a Certificate of Occupancy (final permit sign-off) before any occupancy — rental or otherwise. In most jurisdictions this requires all inspections to pass, utilities to be connected and operational, and smoke/CO detectors installed. Your contractor should walk you through the CO process. Renting before CO is illegal in most cities and can result in fines.

California, Oregon, and many other states removed owner-occupancy requirements in recent years to encourage ADU construction. Requirements vary significantly by municipality. Check your specific city's ADU ordinance — your contractor should know local rules, but verify independently with your city's planning department.

Varies widely: California cities are required to process ADU permits within 60 days. Other states range from 3 weeks to 6 months. Pre-approved ADU plans (offered by many cities) dramatically speed permitting. Hire a contractor with local ADU experience who knows your city's process.

Not automatically. Notify your insurer when the ADU is under construction and update your policy when it's complete. ADU rental activity may also require a landlord or dwelling fire policy for the rental unit. Failure to disclose can result in claim denial — a conversation worth having with your insurer before construction starts.

Yes — common financing options include: HELOC (if you have equity), cash-out refinance, renovation loans (Fannie Mae HomeStyle, FHA 203k), or construction-to-permanent loans. Some states and cities also have ADU-specific financing programs. The rental income from an ADU can often service the additional mortgage payment, making the math work.
