Rent & eviction protection

Is 939 Oak 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

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.

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 multi-family residential building at 939 Oak Street in Hayes Valley, constructed in 1890, contains three units and is currently owned by Arthur C & Linda S Stone Lv. The building's maintenance history includes a reroofing project in 2002 costing $5,500 and repairs to rotting stairs in 2003 valued at $4,000; however, these permits are now expired. The most significant recent development involves a complaint filed in November 2024 regarding unauthorized construction at the rear of the property, including concrete work and wall construction, though this complaint's current status is listed as "Not Active" as of December 2024.

The property has experienced numerous parking-related issues in recent years, with multiple complaints about vehicles blocking driveways and parking on sidewalks between 2018 and 2024. Of particular note are two driveway blocking incidents in 2024 (May and March), though in both cases, officers were unable to validate the reported violations. Other notable incidents include a missing side sewer vent cover reported in February 2023, and graffiti on a pole in February 2019, both of which were resolved. The building's documented history shows regular interaction with city services, primarily concerning parking enforcement issues, which have been consistently addressed by responding officers.

Risk rating

How 939 Oak 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
65thpercentile

Out of 1027 buildings in this neighborhood, 359 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
