Rent & eviction protection

Is 2423 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 1909

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

The property at 2423 Leavenworth Street is a two-story, multi-family residential building located in Russian Hill, consisting of two units and owned by the Huguette Y Combs Trust. Built in 1909, the building underwent significant structural improvements between 2007-2008, including the installation of a new concrete retaining wall and repairs to a landscape retaining wall, with costs exceeding $113,000. The building's interior has seen several updates, most notably a conversion from three units to two units in 2003, which included installing new stairs between floors and completing electrical modifications. Recent improvements include a complete reroofing project in 2019 costing $42,200, and periodic maintenance work such as kitchen remodeling in one unit in 2005.

The property has maintained an active maintenance schedule with completed permits showing regular attention to structural and safety requirements. Historical records indicate two routine housing inspections in 2001 and 2004 with no reported violations. More recently, there have been some neighborhood maintenance issues recorded through 311 calls, primarily regarding abandoned vehicles (with multiple reports between 2023-2024) and general street cleaning matters, though these external issues don't directly affect the building's condition. An overgrown tree pruning request from 2023 remains open, and there was a graffiti incident affecting the mailbox area in July 2024 that was referred to USPS for resolution. The building's documented history suggests careful maintenance and gradual improvements over the years, with no major structural or safety concerns reported in recent years.

Risk rating

How 2423 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
98thpercentile

Out of 1133 buildings in this neighborhood, 23 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
