About Us
ADUs are all we think about
ADU First is a specialist marketing and referral platform built around one thing: helping California homeowners add accessory dwelling units the smart, modern way.
Accessory dwelling units are one of the most practical ways to add space, value, and flexibility to a property - but the path from idea to finished unit can feel complicated. Codes vary by city, build methods differ, and not every contractor treats ADUs as a specialty. That’s the gap we exist to close.
We’re not a contractor. We’re the connective layer between homeowners and a vetted network of local ADU pros - the designers, prefab suppliers, permit specialists, and builders who do this work every day. You tell us about your project; we help match you with the right people to get it done.
How The Network Works
Specialists, not guesswork
A simple, transparent model designed around your project.
A vetted local network
We connect you with independent ADU pros in your area - matched to your project type, lot, and goals.
ADU-focused
Detached, prefab, and conversions are the core of what our network builds - not an occasional side job.
Modern by default
We lean contemporary and prefab-friendly, favoring streamlined designs that fit compact footprints.
What We Value
The standards behind every match
Straight talk
Clear scope and honest expectations. We share the factors that affect your project instead of over-promising.
Right-fit referrals
We aim to connect you with pros suited to your specific project - not a random name off a list.
Space that lasts
ADUs should add lasting value - for rental income, family, or a home office that finally fits.
