Chula Vista Homes with ADU, Casita & Guest House

This page is your guide to Accessory Dwelling Units (ADUs) in Chula Vista, CA. Here you’ll find live MLS listings, local ADU standards and zoning insights for buyers and owners who want casitas, guest houses or multi-generational setups in San Diego’s South Bay.

Chula Vista combines older west-side neighborhoods and newer master-planned communities in Eastlake and Otay Ranch, so ADU options range from backyard second units and garage conversions to attached suites, depending on the lot, zoning and any HOA or community design rules.

Fun Fact: Chula Vista is one of the largest cities in San Diego County by land area, which creates very different ADU profiles between the older grid streets near I-5 and the newer, master-planned communities to the east.

⭐ Local ADU Expertise — Jessica Rinaldi: Jessica reviews Chula Vista zoning, lot layout and any applicable CC&Rs to identify realistic ADU opportunities. She focuses on rear and side-yard access, parking rules near transit corridors and how ADUs fit into established neighborhoods versus newer planned communities, helping buyers avoid properties that look ADU-ready on paper but fail in practice.

Investment Potential: Why Build or Buy an ADU in Chula Vista?

Chula Vista ADUs can tap into strong South Bay rental demand. Legal second units near schools, job centers and freeways often attract long-term renters and multi-gen households.
ADUs create flexibility for multi-generational living and home offices. A detached casita or guest suite can support extended family, aging parents or dedicated workspace apart from the main home.
State ADU laws protect reduced side and rear setbacks. Many compliant ADUs qualify for 4-foot side and rear setbacks, which helps on standard suburban lots across the city.
Multifamily parcels may allow additional ADU density. Qualified multifamily properties can add detached ADUs plus interior conversion units when built to state and local code.
