ADUMetrics is free for homeowners.
Here’s how it works.
Design your unit — or units — and request a quote. Vetted contractors come out to your property to provide estimates, and we stay involved from there. Our job is to hold contractors, architects, and lenders accountable to what they promise. We review the paperwork, verify code compliance, and make sureevery step meets California law.
Our guidance is free, and once your unit is built, we help you lease it out.
The platform includes 100+ templates. Add your address, pick a design, and request quotes — or keep refining until it’s exactly right.
