Rent & eviction protection

Is 2550 Leavenworth 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 1964
2 or more units
4 units
Property type
Multi-Family Residential

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 1964
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, 4-unit multi-family residential building at 2550 Leavenworth Street in Russian Hill has undergone several significant maintenance and improvement projects since its construction in 1964. Most recently, in 2019, the building received updates to its garage with the installation of new wood sectional doors and electrical openers, as well as the replacement of the boiler and storage tank system. In 2015, major works included roofing replacement and repairs to address dry rot and siding issues around the deck. The building has a documented history of addressing violations and compliance issues; most notably, there were two violations in 2004-2006 related to unauthorized modifications including an east-side fence and greenhouse window installation, which were subsequently addressed through proper permitting.

Several maintenance and safety concerns have been documented over the years, including issues with rear exit stairway configuration, fire escape functionality, and weatherproofing. A 2008 complaint highlighted problems with an inoperable door and sanitation issues in common areas, though these were eventually abated by 2011. The building has undergone routine inspections and maintenance, including systematic boiler and water heater replacements in 2010 and 2019, and backflow device installation in 2013. Recent records from 2023-2024 show multiple reports of garbage and debris issues in the vicinity, though these appear to be related to public street conditions rather than direct building management issues. There was one documented incident involving a combustible liquid spill, though no civilian injuries were reported.

Risk rating

How 2550 Leavenworth 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
72ndpercentile

Out of 1133 buildings in this neighborhood, 317 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

Number of units

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
