Rent & eviction protection

Is 136-142 Trenton 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.

Built 1910
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 Wong Revocable Trust owns this 5-unit, 3-story multi-family residential building located at 136-142 Trenton Street in Nob Hill, which was constructed in 1910 and is classified as an Apartment building with 5 to 14 units. The property has undergone several significant safety improvements over the years, including a seismic retrofit completed in 2002 costing $38,000, brick parapet bracing in 1986, and reroofing work done in 1991. The building has undergone multiple routine safety inspections by Housing Inspection Services, with the most recent occurring in 2015, which revealed several violations that were subsequently addressed by August 2015. These violations included the need for carbon monoxide alarms, fire escape maintenance, and stair repairs. A fire complaint regarding blocked exits was also recorded and corrected in August 2011.

More recently, there has been a pattern of street and sidewalk maintenance issues near the property, with multiple 311 calls regarding garbage, debris, and sanitation concerns between October 2024 and January 2025. These calls, while not directly related to building conditions, indicate ongoing challenges with the immediate exterior environment. Two sidewalk blockage incidents were reported in late 2024, one of which remains open as of the latest report date. The building's documented violations and complaints suggest attention to safety systems and regular maintenance has been addressed over time, though the age of the building and its systems may require ongoing monitoring.

Risk rating

How 136-142 Trenton 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
86thpercentile

Out of 1125 buildings in this neighborhood, 158 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
