What actually shapes a project here

The issues, timelines, and project types that come up most often when we work in Los Angeles.
Common Land Use Issues

The most frequent issue we see is parking and density assumptions that don't survive contact with LAMC — SB 1211 now allows up to 8 detached ADUs on qualifying multifamily lots, but lot coverage and fire access limits still trip up first-time applicants.

Older properties also surface deed restrictions or pre-1978 zoning conflicts that don't show up until plan check, which is why we screen for them upfront.

Timelines & Hurdles

Standard ADU plan check now runs 21–60 days when using LADBS pre-approved plans, but custom designs and multifamily projects routinely take 4–8 months once corrections cycles are factored in.

Multifamily permitting is up 85% year-over-year, which means review queues are longer even as approval rules get faster — the bottleneck has shifted from policy to staff capacity.

Notable Project Types

ADU and JADU conversions remain the highest-volume project type citywide. We're also seeing a steady rise in multifamily infill in Downtown LA, South Bay, and Mid-Wilshire.

Garage and accessory structure conversions are the fastest path to additional units for most single-family homeowners.

FAQ

Questions we hear most in Los Angeles

Q. How long does an ADU permit take in LA right now?
Pre-approved plans can move in 21–60 days. Custom designs typically take longer once you factor in plan check corrections.
Q. Can I build more than one ADU on my property?
Possibly. SB 1211 allows up to 8 detached ADUs on qualifying multifamily lots, capped at your existing unit count. Single-family lots are still generally limited to one ADU plus one JADU.
Q. Do I need a CEQA review for a small project?
Most ADUs and many infill projects qualify for a categorical exemption, but multifamily and larger sites often need a closer look — we screen this early so it doesn’t surprise you later.
