SB 721 is the LA multifamily compliance item most likely to surface at the worst possible moment — in escrow, when a buyer's due diligence asks for an inspection report the seller never commissioned. It is not a rent law or a tax law. It is a building-safety law with a hard deadline that has now passed for the first cycle, and it can stall a sale. This is a broker's plain-English explainer of what SB 721 requires and why it matters to a transaction. It is not legal or engineering advice; use a licensed inspector to confirm your building's specific obligations.
SB 721 requires periodic inspection of exterior elevated elements — balconies, decks, stairways, walkways, and their waterproofing — on buildings with three or more multifamily dwelling units. The inspection must be performed by a qualified professional: a licensed architect, a licensed civil or structural engineer, a qualified building contractor, or a certified building inspector. The inspector reports to the owner within 45 days, and owners must keep the reports on file across inspection cycles.
The point of the law is straightforward and grim: elevated structures fail, and the law forces owners to catch deterioration before it becomes a collapse.
The original first-inspection deadline was January 1, 2025. It was then extended by AB 2579 to January 1, 2026. After the first inspection, the building must be re-inspected every six years. That means the first compliance window has now passed: a covered building should already have a completed inspection report on file. If yours does not, that is a gap to close now, not at the closing table.
(A related law, SB 326, covers condominium and HOA-governed buildings on a similar cycle. SB 721 is the one that applies to standard apartment buildings.)
A clean, current SB 721 report is a small thing that makes a transaction smoother, and a missing one is a small thing that makes it harder. Here is how it plays out:
For sellers, commissioning the inspection before listing turns a potential deal-staller into a non-issue. For buyers, the report is a window into the condition of the riskiest parts of the building.
What does SB 721 require?
Periodic inspection of exterior elevated elements — balconies, decks, stairways, walkways, and their waterproofing — on buildings with three or more units, performed by a licensed or certified professional, with a report to the owner within 45 days and records kept across cycles.
What is the SB 721 deadline?
The first inspection was originally due January 1, 2025, but AB 2579 extended that to January 1, 2026, with re-inspection every six years thereafter. The first window has now passed, so covered buildings should already have a report on file.
Which buildings are covered by SB 721?
Buildings with three or more multifamily dwelling units. Condominium and HOA-governed buildings fall under a related law, SB 326.
Do I need an SB 721 report to sell my building?
It is not a transfer prerequisite, but buyers routinely request it in due diligence, and not having one can stall or reprice a deal. Commissioning it before listing is the cleaner path.
SB 721 is the kind of item that is cheap to handle early and expensive to discover late. If you are thinking about selling a building with balconies, decks, or elevated walkways, get the inspection done before a buyer asks for it.
