Garage conversion permits in Long Beach
How to convert a garage conversion in Long Beach: permit pathway through Long Beach Development Services Department, drawings required, local watch-outs, and a free address-level wizard for your Long Beach lot.
Long Beach context
Long Beach's ADU ordinance lives in Long Beach Municipal Code Title 21. The city aligns with the California state baseline plus several local streamlining provisions. Coastal Development Permit (CDP) requirements only apply to the harbor + shore-adjacent parcels (Belmont Shore, Naples Island, downtown harbor). Most of the city is Coastal-Zone-free. The Long Beach Airport (LGB) Airport-Influence Area covers a significant central + east-side swath.

Long Beach watch-outs for garage conversion
Overlays that hit a meaningful share of Long Beach lots

Long Beach Airport (LGB) Airport-Influence Area~45% of parcels

Local quirks
Use the city's Pre-Approved Plan Library if you can
Long Beach maintains a free Pre-Approved Plan Library (PAPL) with several city-vetted ADU designs. Same-day or near-same-day permit issuance on these — significantly faster than custom plans. Worth checking before commissioning a custom designer.
Belmont Shore + Naples lots are tight and Coastal Zone
Long Beach's shore-adjacent parcels are smaller than the inland blocks and require a Coastal Development Permit (CDP). Plan timelines + budget accordingly.
LBUSD school fees apply over 500 sqft
Long Beach Unified School District (LBUSD) — one of California's largest districts — charges school facility fees on ADUs over 500 sqft.
Most of Long Beach is great Accessory Dwelling Unit (ADU) territory
Inland Long Beach has reasonable lot sizes, fast plan check, free pre-approved plans, no Coastal Zone hassle, and rental demand from the port + downtown employment base. The dollar-for-dollar Accessory Dwelling Unit (ADU) economics are some of the strongest in LA County.
