Rent & eviction protection

Is 1685 Union 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.

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 6-unit multi-family residential building at 1685-1699 Union Street in Cow Hollow, owned by the Doris C Yim Living Trust, has a relatively simple maintenance and compliance history since its construction in 1955. The property underwent several maintenance updates in the 1990s, including roofing work and the installation of canvas awnings, with more recent improvements including a garage door installation in 2014. Significant violations were documented in 2000 and 2007, including safety issues related to fire extinguishers, gas meter ventilation, lead-based paint concerns, and interior surface conditions, though all were officially abated by October 2007. A complaint regarding a fence installation affecting tenant security was filed and resolved in 2007. More recent records show no major building code violations since the 2007 resolution. Recent activity at the property has primarily consisted of routine municipal service calls, including street cleaning, noise complaints, and graffiti reports, with the most notable incident being a sewage backup reported in May 2020 and two unrelated fire safety complaints in late 2016 that were found to have no merit. The building's most recent documented issues have been primarily external and environmental in nature rather than structural or safety-related.

Risk rating

How 1685 Union 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
33rdpercentile

Out of 861 buildings in this neighborhood, 577 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
