Rent & eviction protection

Is 523 Octavia St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The property at 523 Octavia Street in Hayes Valley is a two-story, three-unit residential building constructed in 1885, currently owned by Doron Weinberg and Marilyn Wall. The building has undergone significant improvements in recent years, with substantial renovations completed between 2019-2020 including a voluntary seismic upgrade, brick foundation replacement, comprehensive plumbing fixture updates in three bathrooms, interior and exterior painting, carpet replacement throughout both floors, and modifications to create a new hallway configuration on the first floor. The total construction cost for these permitted improvements was approximately $75,001.

In terms of recent incidents and maintenance issues, there was a building inspection complaint filed in March 2022 regarding work not being completed according to plans, though this issue was quickly abated within one day. The property has experienced regular 311 service requests, with the most notable recent incidents in 2026 involving public health concerns including reports of human waste/urine and various debris issues, though most of these cases have been resolved. A carbon monoxide detector activation occurred in June 2023, but no actual carbon monoxide was detected, and there were no civilian injuries or fatalities. The building's maintenance history shows active management, particularly in addressing structural and safety improvements, though the relatively high number of recent 311 service requests suggests ongoing challenges with the surroundings and exterior property maintenance.
