Rent & eviction protection

Is 961-963 Duncan 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.

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 three-story, two-unit multi-family residential building at 961-963 Duncan Street in Diamond Heights, owned by Mary E. Foley, has a documented history dating back to 1983. Notable recent concerns include three "Sleeping Area Requirement" violations issued in late 2023 and early 2024 that remain open and require permit correction, along with multiple fire department responses for smoke detector activations and alarm system issues, though no actual fires or civilian injuries have been recorded. The building has undergone several significant maintenance updates, including double-pane window installations in 2001 (totaling $12,000), window and sliding glass door replacements in 2005 ($10,000), and two furnace replacements in 2010 and 2016. Historical records show a roofing project in 1998, deck and stair repairs in 1993, and fire damage repairs in 1983.

Recent 311 calls from 2023-2024 primarily relate to street maintenance issues outside the building, including multiple pavement defect reports and a parking enforcement matter. The property has experienced several fire safety inspections and complaints over the years, with the most recent violations being the only active issues as of 2024. A tenant buyout occurred at a nearby property (175 Red Rock Way) in 2018 involving two tenants and totaling $20,000, though this may not directly relate to the Duncan Street property. The building's permitting history shows regular maintenance and upgrades, though some permits, including a roofing project from 2001 and a 1993 deck replacement, are listed as expired rather than completed.

Risk rating

How 961-963 Duncan 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
35thpercentile

Out of 17 buildings in this neighborhood, 11 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
