Rent & eviction protection

Is 2459 Polk 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.

Annual rent increase cap

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 12-unit, 3-story multi-family residential building at 2459 Polk Street in Russian Hill, built in 1923, has undergone several significant safety and infrastructure improvements over the past two decades. Most recently, in May 2024, the building completed a major upgrade to its fire alarm system, including the installation of low-frequency sounders in sleeping areas to meet current code requirements, with associated electrical work. The building achieved compliance with San Francisco's soft story retrofit requirements in 2016, and has undergone multiple safety-related upgrades including the replacement of 130 windows in 2006, and various HVAC improvements such as water heater and wall furnace replacements in 2016 and 2009.

The property has a documented history of maintenance and safety compliance efforts, though there have been some notable issues requiring attention. In 2021, Unit 9 reported significant concerns including mold, ceiling leaks, and structural problems attributed to roof issues, while a 2016 complaint documented problems with water quality. The building had several code violations issued in 2009 related to electrical permits, smoke detection systems, plumbing issues, and water damage, all of which were ultimately abated by December 2009. The most recent building inspection records show ongoing attention to infrastructure maintenance, including repairs to drainage systems and various building systems. Recent 311 calls from 2023-2024 primarily relate to street-level issues such as garbage removal and parking enforcement, as well as one construction noise complaint in October 2024, which was associated with valid night work permits for public improvements on Polk Street.

Risk rating

How 2459 Polk 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
7thpercentile

Out of 1133 buildings in this neighborhood, 1054 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
