Rent & eviction protection

Is 2237 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 before 1979
Built 1900

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1900
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 four-story, two-unit multi-family residential building at 2237 Union Street in Cow Hollow, built in 1900 and currently owned by the Carney Family Revocable Trust, has undergone significant renovations and improvements over the past several years. Most notably, in 2022, a turret was added to the existing roof, and in 2018-2019, the property underwent substantial upgrades including the installation of an elevator, fire sprinkler monitoring system, and electrical improvements including a 400-amp service upgrade and solar panel installation. The building's modernization efforts included comprehensive plumbing work, such as the installation of a condensing boiler, radiant heating system, and extensive bathroom and kitchen renovations across multiple floors, with some work specifically noted for both 2235 and 2237 Union addresses.

The property has experienced several significant construction-related activities and some controversies over the years, with multiple excavation and construction permits issued between 2017-2019. There were three building complaints filed in 2019 regarding possible conversion/renovation concerns and construction noise, as well as a 2014 violation related to work exceeding the scope of permitted construction. Planning records indicate various renovation proposals, including a flood improvement project involving floor sealing and backflow valve installation, and a past violation related to unauthorized short-term rentals that has since been resolved. The building's infrastructure has seen substantial upgrades, including comprehensive fire safety improvements, plumbing system replacements, and the addition of modern amenities, though some permits and works have had to be renewed or re-permitted to obtain final inspections.

Risk rating

How 2237 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
15thpercentile

Out of 861 buildings in this neighborhood, 732 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
