California allows multifamily properties to expand housing capacity with at least one ADU inside, up to 25% of existing units, plus two detached ADUs on the same lot. This opens the door for more rental income, flexible housing solutions, and smarter property investments.

How Multifamily ADUs Add Value?

// More Rental Opportunities
· Convert underused spaces like garages, basements, or storage rooms
· Add up to two detached ADUs for additional rental units

// Maximized Property Potential
· Increase unit count without major redevelopment
· Attract long-term tenants with affordable housing options

// Easier Approval Process
· State law requires approval of qualifying ADUs
· Works for both small and large multifamily buildings

For landlords and investors, this is a practical way to increase property value and rental income.
