Escondido’s larger inland lots and relative affordability make it one of San Diego County’s most practical places to build an accessory dwelling unit (ADU). Whether you want rental income or space for family, here is what an ADU costs in Escondido, how permitting works, and how to find a vetted local builder.
Why build an ADU in Escondido?
- Bigger lots. Many Escondido properties have room for a detached ADU without crowding the main home.
- Rental income. Steady inland rental demand makes a backyard unit a reliable income source.
- Multigenerational living. A popular choice for housing aging parents or adult children.
ADU cost in Escondido
Escondido ADU costs are in line with the county: roughly $180,000 to $450,000 for a detached ADU, less for garage conversions and junior ADUs. Larger, flatter lots can sometimes keep site costs down. See our San Diego ADU Cost Guide for the full breakdown.
Permits in Escondido
Escondido handles ADU permitting through the city, separate from the City of San Diego. Statewide ADU rules apply, including the impact-fee waiver for units 750 sq ft or less. Our San Diego ADU Permit Guide covers the overall process; confirm specifics with the City of Escondido.
