Rent & eviction protection

Is 5-7 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.

Built 1910
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 residential building at 5-7 Duncan Street in Bernal Heights, owned by Gregory Landau & Velasco-la, was constructed in 1910 and has undergone several significant renovations over the years. The most substantial interior work occurred in 2005 when kitchen renovations were completed, involving cabinet and counter replacement along with drywall installation, followed by a bathroom remodel and electrical updates. In 2007, gas houseline extensions were completed, though several permits from 2005-2007 related to these renovations had expired or required renewal. The building experienced a cluster of violations in October 2000, including issues with handrails, walls, doorbells, windows, bathroom cabinets, and lead paint hazards, all of which were resolved by November 29, 2000.

More recently, there have been multiple reports of street and sidewalk cleaning issues near the property, with recurring complaints in 2024-2025 regarding garbage, debris, and waste removal, including instances of human waste and needles. As of January 2025, there are open complaints regarding excessive noise in the vicinity. While these exterior issues don't directly affect the building's conditions, they may impact the general living environment. The property's documented history shows consistent maintenance and response to violations, with all building violations from 2000 being addressed within the required timeframe. The most recent building permit activity was related to gas line work in 2007, with no significant interior renovations documented in the past 15+ years, which may indicate either stability in building systems or the need for potential future updates.

Risk rating

How 5-7 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
76thpercentile

Out of 1276 buildings in this neighborhood, 306 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
