Rent & eviction protection

Is 645 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 1913
2 or more units

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 1913
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 114-unit, 5-story multi-family residential building at 645 Leavenworth Street, constructed in 1913 and currently owned by Sic-mcm 825 Post Street Lp, has experienced significant recent challenges, particularly in 2024. There was a notable building fire in March 2024 that affected multiple floors, resulting in resident concerns about smoke damage and toxins, though inspections have not been clearly documented in available records. The building's fire safety systems have been consistently problematic, with multiple violations and complaints in 2023-2024 regarding alarm systems, standpipe systems, and sleeping area requirements. More recently, there are active concerns about a missing fire escape and a potentially dangerous situation with electrical outlets as of October 2024. The building has undergone numerous unit renovations between 2018 and 2020, primarily focusing on kitchen and bathroom remodels in various units, though some plumbing and electrical permits remain expired or in-active status.

The property has experienced recurring maintenance and safety issues, including a gas-related complaint in late 2024, problems with elevator service (notably in January 2023), and multiple tenant complaints about air quality and heating systems following the 2024 fire. Infrastructure maintenance includes a sewer line replacement completed in 2022, while several plumbing and electrical permits show work completed in various units during the renovation period. Historical records from 2003-2005 indicate past concerns with lead paint hazards and electrical violations, though these were resolved. Recent 311 calls (January 2025) primarily relate to exterior maintenance issues like graffiti and sidewalk obstructions. The building's management has documented multiple instances of fire code violations and system-related problems, though many of these issues appear to have been "condition corrected" rather than fully resolved, indicating ongoing maintenance challenges.

Risk rating

How 645 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
8thpercentile

Out of 448 buildings in this neighborhood, 412 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
