Rent & eviction protection

Is 1123 Clay 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.

Built before 1979
Built 1921
2 or more units

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 8-unit multi-family residential building at 1123 Clay Street in Nob Hill, owned by Lee Chester Yam & Wendy, was constructed in 1921 and is classified as a 3-story apartment building with 5 to 14 units. The building has experienced several significant safety and maintenance issues, particularly related to fire safety systems and egress. Between 2000 and 2016, there were multiple fire safety violations documented, including problems with the fire escape system, alarm panel certification, fire extinguisher maintenance, and combustible storage concerns. While many of these violations were eventually abated, they indicate recurring fire safety issues over this time period.

In 2018, there was a fire extinguisher-related complaint that was promptly resolved, and the building's most recent documented fire incident was an alarm malfunction with no civilian injuries. The building underwent reroofing work in 2003 (permit expired) and had a street space permit issued in 2006, though these permits had limited impact on resident safety. Three separate routine inspections (2000, 2009, and 2016) were conducted, with various issues noted and resolved. More recent history includes a 2024 report of a damaged side sewer vent cover and two 2020 incidents involving hazardous materials and an encampment, though these were not directly related to the building's condition. The building has experienced recurring issues with blocked exits, particularly notable in 2011-2012, when multiple complaints were filed with the fire department regarding this safety concern. A significant complaint was filed in 2010 regarding unauthorized work being performed in two units, involving plumbing and electrical modifications without proper permits.

Risk rating

How 1123 Clay St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
44thpercentile

Out of 1125 buildings in this neighborhood, 630 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.
