What buildings are covered by SB 721?

California Health and Safety Code section 17973 applies to buildings with three or more multifamily dwelling units and qualifying load-bearing exterior elevated elements. A property-specific review confirms which elements are in scope.

What exterior elevated elements are inspected?

The law defines elements such as balconies, decks, porches, stairways, walkways, and entry structures that meet its height, occupancy, material, and load-bearing criteria.

How often are SB 721 inspections required?

The statute establishes recurring inspections every six years, with separate timing rules for certain newer buildings and prior inspections. Confirm the current deadline for your property and local jurisdiction.

What affects SB 721 inspection cost?

Cost depends on the number and type of elements, access, available plans and prior reports, required testing, travel, and whether repair engineering is needed. We provide a written scope after the initial free consultation.

What you receive

Every engagement ends in signed documents your contractor can build from and the city can approve.

Balcony inspection report with an element inventory and photo log

01
Element inventory and sampling plan
We identify qualifying exterior elevated element types and plan the required inspection sample.
02
Condition inspection and report
We document accessible load-bearing and waterproofing conditions, photographs, findings, and required next steps.
03
Repair engineering
When deficiencies require structural work, we can prepare repair calculations and details under a separate scope.

How the engineering is done

1
Inventory
Review the property, unit count, prior reports, plans, and exterior elevated elements.
2
Inspect
Examine the selected elements and coordinate additional testing when visual access is insufficient.
3
Report
Provide photographs, condition findings, service-life observations, and recommendations.
4
Repair
Design or verify structural repairs when the report identifies deficient components.
