Why homeowners build
Three ways an ADU works for you.
Monthly cash flow
Long-term tenants, family stays, or short-term rentals — your backyard becomes a paycheck.
Permanent equity
ADUs typically add 25–35% to a property's appraised value the day they're finished.
Flexibility for life
House aging parents, host adult kids, run a studio, or rent it out. The unit adapts as you do.

Testimonials
What homeowners say.
"The fixed-price contract sold us. Six other builders wouldn't put it in writing — ADU Builder did. Final cost matched the proposal to the dollar."
Maria & Roberto G.
Pasadena, CA
"We had a tenant signed before final inspection. The team helped price and list it. We've been cash-flow positive from month one."
James K.
Long Beach, CA
"My mom moved in last fall. We're saving $4K/month versus assisted living and she's 30 feet from her grandkids. Best decision we've made."
