Thinking about building a backyard home in Chula Vista? You are not alone. As one of San Diego County’s largest and fastest-growing cities, Chula Vista has seen strong demand for accessory dwelling units (ADUs) as homeowners add rental income and space for family. This guide covers costs, permits, and how to find a vetted Chula Vista ADU builder.
Why build an ADU in Chula Vista?
- Rental demand. South Bay rents make a backyard unit a strong income source.
- Family flexibility. Many homeowners add an ADU for aging parents or adult children.
- Lot sizes. Many Chula Vista properties have the space for a detached ADU or a garage conversion.
ADU cost in Chula Vista
Costs in Chula Vista are in line with the wider San Diego market: roughly $180,000 to $450,000 for a detached ADU, less for a garage conversion or junior ADU. For the full breakdown by type and size, see our San Diego ADU Cost Guide.
Permits in Chula Vista
Chula Vista handles its own ADU permitting through the city, separate from the City of San Diego. Statewide ADU laws still apply, including the impact-fee waiver for units 750 sq ft or less. Timelines and fees are broadly similar to the rest of the county. Our San Diego ADU Permit Guide explains the overall process; always confirm specifics with the City of Chula Vista.
