SB 721 Balcony Inspections: A Guide for Tri-Valley Owners
What SB 721 requires
SB 721 balcony inspections are required for California rental buildings with three or more multifamily dwelling units. The law, codified at Health and Safety Code section 17973, covers exterior elevated elements more than 6 feet above grade that rely in whole or in substantial part on wood or wood-based products for structural support: balconies, decks, stairways, walkways and landings, along with their load-bearing parts, including guardrails and handrails.
The inspection looks at the condition of those elements and their waterproofing. Under the statute it covers a random sample of at least 15 percent of each type of elevated element. Owners in San Ramon, Dublin, Pleasanton and Walnut Creek with apartment buildings, or small three- and four-unit rentals, should assume they are covered until someone qualified tells them otherwise.

Deadlines: the 2026 date has passed
The original first-inspection deadline was extended by AB 2579 to January 1, 2026. That date has now passed. If your building has not been inspected, the practical step is to hire a qualified inspector now and keep a record of when you did.
After the first inspection, the cycle repeats every 6 years. Local agencies can enforce the law, and the statute allows civil penalties for owners who do not complete required repairs after notice.
Inspector calendars filled up as the deadline approached, and repair contractors follow the same curve. Booking the inspection, then lining up framing, waterproofing and railing trades early, keeps a late start from turning into a long one.

Who performs the inspection, and where we fit
We want to be clear about roles. The SB 721 inspection itself is performed by a licensed architect, a licensed civil or structural engineer, or one of the other qualified inspector categories the statute lists. We do not perform SB 721 inspections.
What we do is the railing side of the repair work: fabricating, repairing and installing guardrails and handrails that the inspection report flags. The law separates the inspector from the contractor who performs repairs, which keeps the process honest and is one more reason to use separate firms for each role.
San Ramon's balcony law page: 15 days and 120 days
The City of San Ramon publishes a California Balcony Laws page for owners. Two timelines stand out:
- 15 days: if an inspection finds an immediate hazard to occupants, it is reported to the Chief Building Official within 15 days, and the owner takes immediate steps such as blocking access or shoring.
- 120 days: for non-emergency repairs, the owner must apply for a repair permit within 120 days of receiving the inspection report.
Read the city's page and the inspector's report together, and call the San Ramon Building Division at (925) 973-2580 if anything is unclear. Dublin, Pleasanton and Walnut Creek apply the same state law through their own building departments.
Getting your building ready for the inspector
A little preparation makes the inspection faster and the report more useful:
- Inventory the elevated elements. List every balcony, deck, stair, landing and walkway more than 6 feet above grade, by unit or building. The inspector builds the sample from that list.
- Gather records. Original plans, past repair permits and any earlier waterproofing or railing work help the inspector understand what is under the surface.
- Notify tenants. Inspectors need access to balconies through units. Give tenants the notice your lease and California law require.
- Clear the balconies. Planters, storage and outdoor rugs hide the exact spots where water damage starts.
- Note known problems. If a tenant has reported a loose rail or a soft spot, tell the inspector so it is looked at directly.
When the report arrives, sort items into emergency, permit-required and maintenance, and line up contractors for each.
SB 721 vs SB 326 at a glance
Condo and HOA buildings fall under a different law, SB 326 (Civil Code section 5551). Many Rossmoor Mutuals in Walnut Creek, for example, are common interest developments under the Davis-Stirling Act, which puts them in SB 326 territory.
| SB 721 | SB 326 | |
|---|---|---|
| Applies to | Rental buildings with 3+ multifamily units | Condo and HOA associations (common interest developments) |
| Statute | Health and Safety Code 17973 | Civil Code 5551 |
| Elements | Elevated elements over 6 ft, wood-supported, incl. guardrails and handrails | Wood-supported elevated elements over 6 ft that the association maintains |
| Who inspects | Licensed architect, licensed engineer or other qualified inspector listed in the statute | Licensed architect or structural engineer |
| Cycle | Every 6 years | Every 9 years |
| First deadline | January 1, 2026 (extended by AB 2579) | January 1, 2025 |
How many Tri-Valley units are in larger buildings
Census data gives a rough sense of exposure. The American Community Survey (2020 to 2024) reports the share of housing units in buildings with 5 or more units:
| City or area | Share in 5+ unit buildings | Approx. units |
|---|---|---|
| Walnut Creek | about 38% | about 13,600 |
| Dublin | about 25.5% | about 6,250 |
| Pleasanton | about 19.7% | about 6,070 |
| San Ramon | about 19% | about 5,900 (about 1,800 in 50+ unit buildings) |
| Danville | about 6% | |
| Alamo | about 2% |
These counts mix rentals and condos and skip three- and four-unit buildings, so treat them as context, not a count of SB 721 buildings.
What failed guardrails usually need, and how we coordinate
When an inspection report flags a guardrail or handrail, the fix usually falls into one of these:
- Re-anchoring loose posts with through-bolts or engineered brackets into sound framing
- Cutting out rusted post bases and welding in new steel
- Raising low guards to 42 inches and closing gaps that pass a 4-inch sphere
- Replacing wood rails on rotted framing with powder-coated steel or aluminum after the framing is repaired
We work from the inspector's or engineer's report and any repair details they specify, fabricate in our shop, and schedule installation around the framing and waterproofing trades so railings go back on last. We prepare railing drawings for the permit and keep the inspector or engineer in the loop if field conditions differ. Once the work is done, we provide the details owners need for their records and the next 6-year cycle.

FAQ
Questions, Answered
Straight answers on cost, code, permits and materials. Still unsure? Call and ask.
Does SB 721 apply to my fourplex in San Ramon?
SB 721 covers buildings with three or more multifamily rental units, so a fourplex with wood-supported balconies, stairs or walkways more than 6 feet above grade is very likely covered. Confirm with a qualified inspector, who will review which elements count. If the building is a condo association rather than a rental, SB 326 applies instead.
I missed the January 1, 2026 deadline. What should I do?
Hire a qualified inspector now and document the date you engaged them. The deadline cannot be undone, but acting promptly puts you in a better position with your local building department. Once you have the report, follow its repair timelines; in San Ramon that includes applying for a repair permit within 120 days for non-emergency items.
Can your company perform the SB 721 inspection?
No. The inspection must be done by a licensed architect, a licensed civil or structural engineer, or another inspector type the statute lists. We handle the railing repair and replacement work that follows, coordinating with the inspector or engineer and preparing railing drawings for the repair permit. The law also keeps the inspector separate from the repair contractor, so using different firms is the expected setup.
How often do SB 721 inspections repeat?
After the first inspection, SB 721 requires a new inspection every 6 years. SB 326, which covers condo and HOA associations, runs on a 9-year cycle. Keep each report on file along with repair permits and final inspections; together they help the next inspector and show the building department that flagged items were completed.
