ADUs present homeowners with flexible space to accommodate multi-generational families, aging parents, rental income potential, and more. Recent California legislation makes it easier than ever to permit ADUs in Chula Vista.

While California legislation sets baseline standards that local jurisdictions must adhere to, cities can customize certain ADU specifications for their communities.
