Rent & eviction protection

Is 1650-1656 Mason 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.

15+ years since occupancy
Built 1925
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 two-story, four-unit multi-family residential building at 1650-1656 Mason Street in North Beach, owned by Hom/teshima Tr, was constructed in 1925 and has undergone several significant events throughout its history. The building experienced a noteworthy series of violations in November 2007, when multiple safety and maintenance issues were documented, including problems with walls/ceilings, water heater seismic bracing, door security, and various fire safety requirements such as fire extinguishers and utility shutoff tools. All these violations were officially abated by December 17, 2007. More recent records show routine housing inspections in 1999, 2004, and 2011, suggesting regular oversight of building conditions.

The property has undergone some structural maintenance work over the years, including a reroofing project completed in 1991 and a door replacement project in 1989. While there have been two fire-related incidents recorded—an accidental alarm activation and a gas leak—both occurred without civilian injuries. The building's location has experienced frequent parking enforcement issues, particularly in recent years, with numerous calls made between 2020 and 2025 regarding vehicles blocking driveways, parking on sidewalks, and other violations. Most of these cases were either resolved through citations or resulted in officers being unable to locate the offending vehicles.

Risk rating

How 1650-1656 Mason 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
58thpercentile

Out of 362 buildings in this neighborhood, 152 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
