Balcony inspection in Marin: SB 721 and SB 326
In Marin, apartment buildings with three or more units follow SB 721, with an inspection every 6 years. Condos and HOAs with three or more units follow SB 326, every 9 years. Both cover wood balconies, decks, stairs and walkways more than six feet above the ground. I live and work in Marin, so your building is close to home. I inspect every one myself, as a California licensed Professional Engineer.
Which law applies to your building
| Your building | Law | How often | Who must act |
|---|---|---|---|
| Apartments, 3 or more units | SB 721 | Every 6 years | Building owner |
| Condos and HOAs, 3 or more units | SB 326 | Every 9 years | HOA board |
The first SB 326 deadline was January 1, 2025. The first SB 721 deadline was January 1, 2026. If yours has not been done, it is late. Send me the address and I tell you where you stand, free.
Close to home
Marin is where I live and work. Hillside lots, decks over slopes and buildings near the water see a lot of moisture, and water is what ruins wood balconies. I look closely where it gets in. I also cover Petaluma in Sonoma County.
