Rent & eviction protection

Is 201 Masonic 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 1941

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

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 1941
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-unit multi-family residential building at 201 Masonic Avenue in San Francisco's Lone Mountain neighborhood was constructed in 1941 and is owned by the Ronald Vallee Revocable Liv Trust. The property has undergone several significant maintenance and upgrade projects over the years, most notably two complete reroofing projects in 1997 and 2016 (the latter costing $18,000), and multiple electrical system improvements including an upgrade from fuse to circuit breaker service in 2005, the installation of a gas forced air furnace in 2013, and an attempt to install two garage door openers in 2007 (though this permit expired without confirmation of completion).

The building has experienced a pattern of graffiti incidents in recent months, with multiple reports between October and November 2024 affecting the sidewalk, poles, and the building itself. While these incidents were addressed by city services, they represent the most significant recent maintenance concern. The property has had minimal fire-related incidents, with only one recorded electrical wiring/equipment problem (date not specified) and no civilian injuries reported in any of the fire-related calls. The building's utility and public service interactions have been generally routine, including several resolved garbage and debris cases between October 2024 and January 2025, along with some utility billing matters and transportation service requests. The most recent building-related incident was a garbage and debris report in January 2025, which was also resolved. While the property has maintained its basic infrastructure through regular updates, the cluster of graffiti incidents in late 2024 suggests an area-wide maintenance challenge rather than a specific building issue.

Risk rating

How 201 Masonic 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
64thpercentile

Out of 519 buildings in this neighborhood, 187 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
