Rent & eviction protection

Is 2744-2748 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.

Built 1936

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.

15+ years since occupancy
Built 1936
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

This 3-unit multi-family residential building, located at 2744-2748 Union Street in Cow Hollow, was constructed in 1936 and is owned by Union Street Tr. The property has undergone several significant renovations over the past decade, with the most recent work completed in October 2023 involving upgrades to two bathrooms including new fixtures and wall tiles, with associated electrical and plumbing work now completed as of February 2024. Earlier improvements include substantial kitchen and bathroom renovations in 2015 totaling approximately $32,000, and re-roofing work in 2019 costing $27,000. The building experienced notable issues with lead paint hazards in 2013, leading to multiple complaints and violations regarding damaged paint and unsafe containment practices, though these were abated by February 2014. Historical records show earlier maintenance work in 1999 addressed rot and fungus damage in the lightwell, and in 1992 the linoleum flooring in the kitchen and laundry areas was replaced.

The property has maintained regular upkeep of essential systems, including electrical upgrades with the installation of a new 200-amp main service in 2015, though there were two electrical permit expirations during that renovation period. The building's exterior and surrounding area have seen various maintenance activities, including street space and sidewalk repairs in 2016, though there have been occasional issues with garbage debris (most recently in September 2024) and abandoned vehicles near the property, which were resolved through normal enforcement channels. Recent inspection history shows no active violations, and all identified issues have been properly addressed, with the last lead-related complaints being resolved in 2014.

Risk rating

How 2744-2748 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
94thpercentile

Out of 861 buildings in this neighborhood, 52 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
