Rent & eviction protection

Is 2353 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.

Built 1924
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 4-unit, 2-story multi-family residential building at 2353 Union Street in Cow Hollow, owned by Michaelis Alice Trst, has a recorded history dating back to its 1924 construction. The property has undergone several significant maintenance and safety improvements over the years, including a sewer line replacement in 2015, installation of a water heater in 2014, and two complete reroofing projects in 1989 and 2006, with the most recent roofing work costing $6,200. Accessibility improvements were made in 1995 with the installation of a stairlift serving one unit. The building has experienced two routine housing inspections (2000 and 2008), which resulted in violations related to self-closing doors and handrail repairs, though these issues were promptly addressed and abated within several months.

Recent building activity has primarily involved infrastructure maintenance, with the most pressing current issue being tree root damage to the sidewalk as reported in February 2024. The property has experienced multiple fire alarm activations over the years, though all incidents were determined to be unintentional with no civilian injuries reported. The building's service history suggests regular maintenance of core systems, though there are recurring issues with parking enforcement in the immediate vicinity, as evidenced by multiple 311 calls regarding blocked driveways throughout 2019-2024. Tree maintenance has also been a recurring concern, with several reports of damaged and potentially hazardous trees between 2019-2020, including one incident involving significant vehicle damage.

Risk rating

How 2353 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
42ndpercentile

Out of 861 buildings in this neighborhood, 499 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.
