Permit & Zoning Compliance in Los Angeles

ADU construction must comply with:

Local zoning regulations
Setback requirements
Height limitations
Utility connection guidelines

All submissions and inspections are coordinated through the
Los Angeles Department of Building and Safety (LADBS)

Proper planning ensures legal rental eligibility and resale value.

Why an ADU Is a Smart Investment

Los Angeles has strong rental demand and limited housing supply.

A fully permitted ADU can:

Offset mortgage payments
Produce consistent monthly rental income
Increase property equity
Add legal livable square footage
Boost resale value

When built properly and approved through LADBS, an ADU becomes a legal, income-producing extension of your property — not just an addition.
