This is general information, not legal advice. Laws change; check the sources below and the city for the current rules.
What “ministerial” means
Most building in Los Angeles goes through discretionary review: hearings, appeals and conditions that can change late in the process. Ministerial review means city staff check the plans against written, objective standards. If the project meets them, it’s approved. No hearing, no appeal on taste.
For buyers, this matters because time is cost. Every month a builder waits for approval adds interest and holding costs that end up in the price of the home.
What the law requires of a project
Under the original SB 684 rules, a qualifying project generally needs to:
- be on an infill site zoned for multifamily housing
- have 10 or fewer homes
- keep the average home size at or under 1,750 square feet
- meet the zone’s minimum density where the city’s housing plan requires it
It excludes very high fire hazard severity zones, wetlands, prime farmland and protected habitat. It also excludes sites with rent-controlled or deed-restricted units, sites occupied by tenants in the past five years, and sites withdrawn from the rental market under the Ellis Act in the past 15 years.
What changed in 2026
SB 1116 was written to fix problems cities hit while putting SB 684 into practice. Cities can still cap height in feet but can’t separately cap the number of stories. Setbacks between the new lots are generally gone unless the building code requires them. Cities must send their local rules to the state housing department, which can flag rules that block the law.
What it means if you want to buy
- More new for-sale homes in established neighborhoods, not only condos and apartments.
- Homes on their own land, like small lot homes, at prices below a detached house on a full property.
- Shorter waits between land purchase and construction, which helps keep prices in check.
- Homes, not empty lots: because of AB 130, you’ll be buying a home that’s built or under construction, not a lot you have to build on yourself.
How Vivienda uses it
We look for properties where these laws already allow several homes, using our own software, Atlas, then confirm the details with the city before buying. Read how we find the land or check whether your property is zoned for more homes.
Questions people ask
Does SB 684 mean no approval is needed?
No. The city still reviews the project against objective standards like height, fire safety and utilities. What changes is that there's no public hearing and the review is ministerial, meaning staff check it against written rules rather than vote on it.
How long does approval take?
State law now requires agencies to act on complete applications for ministerial projects within set deadlines (30 days to respond and 60 days to decide under AB 130, with exceptions). Real timelines depend on how complete the application is.
Where doesn't it apply?
It excludes very high fire hazard severity zones, sensitive habitat and farmland, and properties with rent-controlled units, recent tenants (five years) or Ellis Act withdrawals (15 years).
Can I buy a lot and build later?
Generally no. Under 2025 changes (AB 130), new lots generally can't be sold or financed until a home is built on them, with limited exceptions.
