Rent & eviction protection

Is 144-146 4Th Ave 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 1903

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

This three-story multi-family residential building, constructed in 1903, contains two units and is owned by Wong Kwok-ho & Ng Mai Sim. The property has experienced several maintenance and compliance issues over the past two decades, with the most recent activity being a stair repair completed in September 2023. The building has a history of significant stair-related concerns, including a December 2017 complaint about disrepair that was eventually addressed by November 2018. There were also multiple violations related to lead paint hazards, window glazing, and an unauthorized rear structure constructed in 2003. In 2007, the property underwent reroofing work, but there were complaints about unauthorized roof demolition and debris management during this period. More recently, in September 2023, there was a complaint about unpermitted front staircase replacement work, though this was followed by the proper repair permit obtained in September 2023. The building's exterior areas have experienced recurring issues with parking enforcement, with numerous reports of driveway blocking between 2024 and 2025, and there is currently an open issue regarding a collapsed sidewalk reported in August 2024. A tenant buyout occurred in 2015 for $45,000 at a neighboring address (152 4th Avenue), but there are no records of similar actions at this property directly.

Risk rating

How 144-146 4Th Ave'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
39thpercentile

Out of 660 buildings in this neighborhood, 403 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
