Rent & eviction protection

Is 10 Bannan Pl 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.

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 multi-family residential building at 10 Bannan Place, owned by Survivor's Trust, was constructed in 1910 and currently contains three units. The property has undergone significant renovations and maintenance work over the past decade+, with major improvements including comprehensive unit upgrades in 2012 (valued at $15,000), installation of new plumbing systems (including a gas line replacement due to a leak in 2016), electrical upgrades (including a new 400-amp service in 2010), and multiple heating system improvements. During 2008-2015, the building experienced several code compliance issues, particularly regarding fire safety and lead paint hazards, including violations related to fire escape access, fire extinguishers, and community kitchen maintenance, though all these violations were marked as abated by 2015.

Of particular concern are recent complaints from 2018-2019 suggesting possible unauthorized units within the building, inadequate fire escape access, and overcrowding issues, though these complaints are currently listed as "Not Active" or "Active" with unclear resolution status. Fire safety inspections and complaints regarding shared spaces have been recurring, with the most recent concerns filed in 2024 regarding sprinkler systems and shared space access, though these were deferred. The building's maintenance history shows regular attention to infrastructure systems, including multiple plumbing upgrades, heating system improvements, and electrical system overhauls, though several permits have expired or been cancelled during the process. The property's location has seen periodic street-related service calls in 2023-2024, primarily regarding sidewalk cleaning and parking issues, though these are external to the building itself.

Risk rating

How 10 Bannan Pl'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
59thpercentile

Out of 684 buildings in this neighborhood, 280 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
