Rent & eviction protection

Is 939 Clayton 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 1965
2 or more units

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 1965
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-story, two-unit multi-family residential building at 939 Clayton Street in the Parnassus/Ashbury Heights neighborhood, owned by Mccoy Waukeen, has a history spanning several decades since its construction in 1965. The building underwent significant interior improvements in 1998, including bathroom remodels and kitchen renovations, and received a new roof in 1992. More recently, there have been multiple concerning issues regarding unpermitted construction activity, particularly related to a roof deck installation. Complaints were filed in February 2022 and November 2018 regarding unauthorized roof deck construction, including the installation of a hot tub and reported unsafe conditions. A plumbing permit from 2014 documented the replacement of a 48-gallon water heater. Additionally, there has been a significant pattern of parking violations in the vicinity of the property in 2024, with at least ten complaints regarding blocked driveways and sidewalk parking, resulting in several citations being issued.

The building's recent maintenance history shows some activity, with a streetspace permit issued in 2018, though the current status remains ambiguous. The property continues to experience recurring issues with illegal parking, particularly evident in 2024 with multiple citations for blocked driveways and sidewalk parking. While the documented building improvements from the 1990s and the 2014 water heater replacement indicate some level of maintenance, the lack of recent permitted major renovations and the ongoing concerns about unpermitted construction from 2018-2022 warrant attention. The building's exposure to potentially hazardous construction practices, particularly concerning stone countertop work with harsh chemicals on public property as reported in 2022, represents a notable safety concern.

Risk rating

How 939 Clayton 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
