Why SB 326 and SB 721 Exist
California's balcony inspection laws grew out of tragedy. After a deck collapse caused loss of life, the state moved to require periodic inspection of the load-bearing decks, balconies, stairways, and walkways that are elevated above the ground and depend on wood or wood-based framing. Two laws now govern this: SB 326 for condominium and homeowners' association buildings, and SB 721 for apartment buildings with three or more units.
For HOA and condo boards across the Sacramento region, the foothills, and Tahoe, these are not optional maintenance suggestions — they are statutory obligations with real deadlines and real liability for boards that miss them. The rules can be confusing, and the roles are easy to mix up. Below are six facts every California board and property manager should have straight. This is general information, not legal advice; confirm specifics for your building with a qualified professional and your association's counsel.
1. SB 326 Covers Condos; SB 721 Covers Apartments
The first question is which law applies to your building
SB 326 applies to condominiums and buildings governed by a homeowners' association — it amended the Davis-Stirling Act, which governs common-interest developments. SB 721 applies to apartment buildings with three or more multifamily dwelling units that are not HOA-governed.
The distinction matters because the laws have different inspection standards, sampling requirements, and timelines. If you sit on a condo or HOA board, SB 326 is your statute; if you own or manage a rental apartment complex of three-plus units, SB 721 governs. When ownership structure is mixed or unclear, confirm which applies before scheduling an inspection.
2. They Target Exterior Elevated Elements
Load-bearing structures over walking surfaces
Both laws focus on exterior elevated elements (EEEs): decks, balconies, stairways, walkways, landings, and their railings that are more than six feet above ground and rely on wood or wood-based products for structural support. These are the assemblies most vulnerable to hidden water intrusion and dry rot, which is exactly what caused the failures the laws respond to.
The inspection specifically evaluates the load-bearing components and the associated waterproofing — flashing, membranes, coatings, and sealants — because a balcony usually fails from water getting into the framing where you cannot see it, not from visible surface wear.
3. A Licensed Architect or Engineer Does the Inspection
The statutory inspection is not a contractor's job
This is the most commonly misunderstood point. Under SB 326, the statutory inspection must be performed by a licensed architect or licensed structural engineer (SB 721 additionally allows certain other qualified, licensed professionals). The inspector's job is to assess the condition of the load-bearing components and waterproofing and produce a report on their current condition and remaining useful life.
In other words, the inspection and the repair are two separate roles. A general contractor does not perform the statutory SB 326 inspection — that independent assessment comes from the licensed design professional. Keeping those roles distinct protects the board and keeps the inspection objective.
4. Know Your Inspection Deadlines and Cycles
These inspections recur on a fixed cycle
Both laws set an initial inspection deadline and then require re-inspection on a recurring cycle — SB 326 ties its ongoing inspections to a periodic cycle for HOAs, and SB 721 sets its own recurring interval for apartments, with follow-up as conditions warrant. The initial compliance dates for existing buildings have already been established by statute, so boards that have not yet completed a first inspection should treat it as overdue and act promptly.
Because deadlines and intervals have specific statutory dates and can be updated, confirm the exact current requirements for your building type with a qualified professional or your association's counsel rather than relying on memory. Building the recurring inspection into your reserve study and maintenance calendar keeps the association from scrambling as each cycle comes due.
5. A Contractor Handles the Repairs
Where a qualified contractor comes in
When an inspection identifies damage or conditions that threaten the safety of an exterior elevated element, the follow-up repairs are performed by a licensed contractor — not the inspecting design professional. This is the other half of the two-role structure: the architect or engineer inspects and specifies, and the contractor executes the repairs.
Repairs commonly involve replacing rot-damaged framing, rebuilding decks and balconies, and — critically — correcting the waterproofing, flashing, and drainage that let water in to begin with. Our deck and balcony inspection service supports boards on the repair side and helps coordinate the process once a report identifies work that needs to be done.
6. Consequences of Ignoring the Requirement
Liability, safety, and enforcement all point the same way
Skipping or delaying required inspections exposes a board on multiple fronts. Beyond the obvious safety risk to residents, non-compliance can create liability for the association and its directors, complicate insurance, and — for apartments under SB 721 — expose owners to enforcement and potential penalties from the local building department. A deferred balcony problem also tends to get more expensive the longer water works on the framing.
The practical takeaway: treat the inspection cycle as a standing obligation, budget for both the inspection and likely repairs in your reserves, and keep the inspecting professional and the repair contractor as distinct, coordinated roles. If your association is planning repairs after an SB 326 or SB 721 inspection, request a free estimate and we will help you scope the work.

What is the difference between SB 326 and SB 721?
SB 326 applies to condominiums and buildings governed by a homeowners' association, amending the Davis-Stirling Act. SB 721 applies to apartment buildings with three or more units that are not HOA-governed. Both require periodic inspection of exterior elevated elements — decks, balconies, stairways, and walkways with wood-based structural support — but they have different inspection standards, sampling, and timelines, so the first step is identifying which law governs your building.
Who is allowed to perform an SB 326 balcony inspection?
Under SB 326, the statutory inspection must be performed by a licensed architect or a licensed structural engineer. SB 721 additionally allows certain other qualified, licensed professionals. The key point is that this is an independent assessment by a licensed design professional — a general contractor does not perform the statutory inspection. The contractor's role comes afterward, performing any repairs the inspection identifies.
How often do these inspections have to happen?
Both laws require an initial inspection and then re-inspection on a recurring cycle, with SB 326 and SB 721 each setting their own intervals and follow-up requirements. The statutory dates for existing buildings have already been established, so any board that has not completed a first inspection should treat it as overdue. Because exact deadlines and intervals are set by statute and can change, confirm the current requirements for your building with a qualified professional.
What happens if our HOA board ignores the inspection requirement?
Non-compliance exposes the association and its directors to liability, can complicate insurance, and — for apartments under SB 721 — can lead to enforcement and penalties from the local building department. There is also the real safety risk to residents, since these inspections exist because water-damaged balconies can fail. Deferring the issue usually makes eventual repairs more expensive, so the practical approach is to budget for the inspection cycle and repairs in your reserves.
