It generates rental income, adds resale value, houses aging parents or adult children, and — unlike a pool — tends to pay for itself. Since California's 2017 reforms, building one is closer to a standard remodel than a rezoning fight.
Modeno Builders builds ADUs across Orange County, Los Angeles, Ventura, and Riverside — garage conversions, attached units, and ground-up detached builds — and manages the permits, engineering, and utility connections in-house.
Most well-built ADUs cover their build cost in 6–12 years of rental income, and appraisers credit 60–80% of build cost to your home's appraised value. The income stream and the optionality — house family now, rent later — are often worth more than the appraisal bump.
