Rent & eviction protection

Is 121 Scott 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.

Built before 1979
Built 1900

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.

Built 1900
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 121 Scott Street in Hayes Valley, owned by Crump Walter Gray Jr, has undergone several significant improvements and faced various challenges since its construction in 1900. Most notably, in June 2023, the building experienced a serious foundation issue when neighboring excavation work exposed a section approximately 4 feet below the footing and 8 feet wide, requiring urgent underpinning work that was completed in June 2023. The building has received consistent maintenance and upgrades over the years, including a 2005 electrical service upgrade to 200 amps with five meters for four units, the installation of an electric vehicle charging station in 2017, and multiple safety improvements such as a kitchen hood installation with fire suppression system in 2015. Historical records show previous major works including foundation repairs for dryrot and faulty grade in 1988, garage renovations in 1995, and exterior stair replacements in 1997.

The property has faced several regulatory and safety challenges, particularly in relation to fire safety systems. In 2002, the building received violations regarding central alarm system certification and garbage receptacle placement, which were resolved by June 2003. A fire safety violation was also recorded in 2020 related to combustible materials. More recently, in late 2024, there have been multiple parking enforcement calls regarding blocked driveways, with at least five citations issued between November 2024 and January 2025. The building currently has an open noise complaint from December 2024 and a missing side sewer vent cover issue reported in November 2024. While the property has experienced its share of maintenance and regulatory challenges, it has also benefited from regular upkeep and modernization efforts, as evidenced by the various permits and improvements documented over the years.

Risk rating

How 121 Scott 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
28thpercentile

Out of 1027 buildings in this neighborhood, 739 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
