SB-721 Explained
Understanding SB-721 Balcony Inspection Requirements
What California property owners need to know about exterior elevated element inspections and compliance.
The Law
What is SB-721?
California Senate Bill 721 (SB-721) requires periodic inspections of exterior elevated elements (EEE) in multifamily rental properties. These elements are typically exposed to weather and supported by wood framing, making them vulnerable to long-term deterioration.
SB-721 was enacted to reduce life-safety risks associated with structural failure caused by moisture intrusion, decay, and lack of maintenance.
Exterior Elevated Elements
- Balconies
- Decks
- Walkways
- Stairways
Applicability
Who Must Comply?
SB-721 applies to multifamily rental properties with three or more dwelling units that have exterior elevated elements supported by wood framing. This includes:
- Duplexes, triplexes & four-plexes
- Apartment buildings
- Small and large rental properties
