California didn’t leave multifamily property owners with a choice. If your building has three or more rental units and exterior balconies, decks, or stairways sitting higher than six feet off the ground โ they must be inspected. The catalyst was a disaster in Berkeley: a balcony held up by wooden beams that had rotted through collapsed in 2015. Nothing on the outside hinted at danger. Six people dead, seven injured. The state learned its lesson and wrote it into law.
SB 721 is Section 17973 of the Health and Safety Code. It compels rental property owners to conduct periodic inspections of exterior elements built on wood framing. The first deadline โ January 1, 2025 โ has already come and gone. In Sacramento, the team at AbdInspections https://abdinspections.com/sb-721-inspection/ handles these assessments from the initial walkthrough all the way to final repairs. Follow-up inspections are required every six years, and putting them off is an expensive gamble: fines for each day without a completed inspection run up to five hundred dollars.
Who the Requirement Applies To
Some owners only found out about the law by accident โ from an insurance carrier or a neighboring property manager. Yet the list of buildings that fall under SB 721 is broader than most people assume.
Properties subject to inspection include:
- Multifamily rental buildings with three or more units
- Triplexes and fourplexes with exterior elevated structures
- University campuses and student housing complexes
- Senior living communities with open walkways and stairways
- Mixed-use buildings where residential floors share the structure with commercial space
The law is tied to framing material. If the load-bearing components of a balcony or deck are made of wood or wood-based composites, the property falls under SB 721. Fully steel or reinforced concrete structures are excluded. That said, there’s no reason to assume you’re in the clear: figuring out what’s actually inside the framing often requires opening up the cladding, and that’s exactly what the inspection is for.
What the Inspection Looks Like From the Inside
Walking around the building and eyeballing the exterior is only the beginning. The inspector examines every elevated element for cracks, deflection, peeling coatings, and moisture stains. But the real value of an SB 721 assessment lies in the invasive testing component. The law requires opening up at least fifteen percent of each type of structure to see what’s hidden behind the finish.
Through small control openings, the specialist inserts a borescope camera and documents the condition of joists, ledger boards, metal connectors, and the waterproofing layer. This is where surprises tend to show up: moisture accumulates for decades at wall-attachment points, and wooden members lose their load-bearing capacity while still looking perfectly intact from the outside. Corroded hardware makes things worse โ a weakened bolt or bracket can be the last link before a collapse. Once testing wraps up, every opening is carefully sealed.
The outcome is a thorough report. The document catalogs every defect found, assigns each one an urgency rating, includes photographs, and lays out specific repair recommendations. If conditions are critical, the law requires notifying the local building department and launching repairs on a compressed timeline.
Working With AbdInspections: The Process
The company operates out of Sacramento and serves surrounding areas throughout California. A single team runs the project from beginning to end โ which eliminates the coordination headaches that come from splitting the inspector and the repair crew into separate contracts.
- Preliminary property evaluation: building type, number of exterior elements, applicable regulations, and a clear estimate with no surprise charges at the finish
- Field inspection combining visual assessment with invasive testing using borescope equipment
- Report preparation with photographic documentation, damage classification, and repair recommendations
- Defect remediation by the in-house construction crew โ from replacing individual joists to full deck and railing reconstruction
- Final compliance documentation ready for submission to municipal authorities and the insurance provider
Repair materials include Trex, TimberTech, natural Redwood, and Westcoat waterproofing systems. Warranty on completed work extends up to five years. Every major project is overseen by a superintendent with more than a thousand inspections behind him.
What Happens When You Ignore the Law
Five hundred dollars a day is just the starting point. During a municipal enforcement visit, each violation is assessed separately, and a single one can carry a penalty of up to five thousand. Insurers are increasingly asking for a copy of the inspection report at policy renewal, and without one, coverage terms deteriorate sharply.
The worst-case scenario is an accident on a structure that was never inspected. A missing inspection certificate gets treated in court as direct evidence of owner negligence. Case law in California on these matters consistently favors the injured party โ compensation awards run into the hundreds of thousands, and that’s before factoring in reputational damage.
