Rent & eviction protection

Is 2455 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

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 15-unit multi-family residential building at 2455 Polk Street in Russian Hill, constructed in 1911, has undergone significant maintenance and upgrades over the past decade. Most notably, in 2021, the building upgraded its fire alarm system to comply with San Francisco Fire Code requirements, including the installation of low-frequency sounders in sleeping areas. In 2019, there was a fire safety violation related to sprinkler service that was subsequently abated. The building demonstrates a commitment to structural safety, having completed a soft-story retrofit in 2013 that included strengthening of the first floor and basement. Between 2008 and 2013, multiple unit renovations were performed, including comprehensive kitchen and bathroom remodels in units A, 8, 9, 10, and 3, with upgrades to appliances, fixtures, and electrical systems.

The property has experienced some security concerns, with complaints in 2009 regarding insecure stairwell doors and overall security, though these issues are now listed as not active. Recent maintenance has primarily focused on building systems and tenant improvements, with no major structural or safety violations noted in recent years. The building's management has regularly addressed necessary repairs and upgrades, including multiple street space permits and various infrastructure improvements. A series of 311 calls in 2024 primarily related to street cleaning and debris removal have been resolved, indicating active responsiveness to maintenance needs in the surrounding area.

Risk rating

How 2455 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
