Rent & eviction protection

Is 1451-1453 18Th 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 before 1979
Built 1927
2 or more units
3 units
Property type

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1927
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 three-unit residential building at 1451-1453 18th Avenue in San Francisco's Inner Sunset neighborhood, owned by Lam Tom Ming To, has undergone several significant improvements and maintenance work since 2015. Most notably, between 2017-2018, the building received comprehensive safety upgrades including the installation of a fire sprinkler system (completed in March 2017), electrical system updates with a new 200-amp main service and individual unit panels, and a new furnace installation. The upper unit underwent cosmetic remodeling in 2018, including kitchen and bathroom updates, while necessary maintenance work was performed to address termite damage and dry rot, particularly in the stairs and siding, following a 2018 inspection. The building's infrastructure has been maintained with a $22,000 reroofing project completed in 2019.

The property has experienced some functional issues over the years, including two documented sewer-related incidents (2016 and 2021), and there have been several parking enforcement matters in the vicinity. A sidewalk defect was noted in 2013, which was brought to the owner's attention. The building's ownership history includes efforts to legalize an existing residential unit installed behind the garage, which was successfully completed in 2017. Street improvement permits were also obtained in 2017, suggesting attention to the building's exterior and access areas. Recent 311 calls (2021-2023) have primarily related to general street maintenance and parking issues, though these are not directly related to the building's condition or maintenance.

Risk rating

How 1451-1453 18Th 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
41stpercentile

Out of 1493 buildings in this neighborhood, 881 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
