Rent & eviction protection

Is 106-108 Beaumont 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 1940

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 1940
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 Karsant Family Trust owns this two-unit, two-story multi-family residential building located at 106-108 Beaumont Avenue in the Lone Mountain neighborhood. Built in 1940, this flats and duplex structure has undergone several significant improvements over the years, with the most recent being a noise-related complaint in January 2024 regarding construction work that reportedly caused high-pitched gnawing sounds and blower noise affecting nearby residents' sleep, though this issue was abated within two days. The building has seen substantial maintenance and upgrades, including the replacement of 15 windows in 2008 (valued at $20,188) to meet current egress requirements, a complete reroofing in 2007 ($14,800), and gas houseline extension work in 2012. Earlier improvements include repairs to address dryrot in 1997, roof deck modifications in 1994, ground-level decking and brick patio installation in 1992, and the enclosure of a central lightwell with skylight in 1988. The property's maintenance record indicates regular upkeep and modernization efforts, with the most recent building permit activity focusing on window replacements and gas line modifications. In addition to housing-related issues, there have been occasional neighborhood concerns such as a driveway blocking incident in February 2023 and a tree staking matter in March 2009, both of which were resolved through appropriate channels.

Risk rating

How 106-108 Beaumont 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
