Rent & eviction protection

Is 2740 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 1924

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

2740 Union Street is a three-story, three-unit multi-family residential building located in Cow Hollow, constructed in 1924 and currently owned by Gb Trust 2008. The property has undergone several significant improvements over the past two decades, with the most recent work being a reroofing project valued at $25,500 in November 2023. Major renovations have included a comprehensive third-floor renovation and electrical upgrade in 2004, the creation of additional bedrooms and a bathroom in the basement in 2013-2014, and kitchen and bathroom remodels in multiple units throughout the building. Notably, Unit #1 received significant upgrades in 2016, including kitchen and bathroom remodeling with associated electrical and plumbing work, and was equipped with a fire sprinkler system in 2014.

The building has a history of addressing safety and habitability concerns, with all identified violations from a 2000 inspection being corrected by October 2000. These violations included issues with egress obstruction, door security, fire extinguishers, and gas shutoff tools, all of which were properly abated. A fire alarm system issue was reported in late 2021 but was resolved within two months. The property has also seen various infrastructure improvements, including a garage door widening project in 2004 and multiple street space permits. Recent 311 calls primarily relate to street-related issues, with the most recent being parking violations in July 2024, while earlier calls from 2013-2019 involved general street cleaning and hazardous materials concerns that were subsequently addressed.

Risk rating

How 2740 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
68thpercentile

Out of 861 buildings in this neighborhood, 276 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
