01
Why Calabasas homeowners build ADUs
Calabasas is one of West Valley's strongest markets for accessory dwelling units. Property values in the neighborhood have appreciated steadily, rental demand is consistent, and California state law gives Calabasas homeowners powerful new rights to add a permitted ADU to their lot.
Calabasas ADUs serve high-end rental and multi-gen use, with strong long-term equity benefits. For families, an ADU means flexible space for aging parents, adult children, or a dedicated home office. For investors, it means $2,000–$5,000/month in rental income and meaningful resale appreciation.
AER Builders™ designs and constructs ADUs, JADUs, garage conversions, and home additions across Calabasas and the surrounding West Valley — managing architecture, permits, and construction under one accountable team.

Rental income
Detached ADUs in Calabasas typically generate $2,900–$5,000 per month in long-term rent.

Flexible use
Use the ADU as a rental, a home for family, a work-from-home suite, or a long-term guest house.
03
Permits in Calabasas
Calabasas issues its own permits. HOA architectural review is common and must be coordinated with city approval.
California's state ADU laws (SB 9, AB 2221, and related legislation) override most older local restrictions — meaning Calabasas homeowners typically have ministerial approval pathways for compliant ADU designs. We handle the entire permit submission, plan check, and inspection process.

Rental income potential in Calabasas.
Based on current market rents, a well-built detached ADU in Calabasas typically generates $2,900–$5,000 per month in long-term rental income. Smaller garage conversions and JADUs typically rent below this range; larger 2-bedroom detached units rent above it.
For most Calabasas homeowners, that rental income exceeds the monthly debt service of an ADU construction loan, making the project cash-flow positive from day one — and adding lasting equity to the property.
