Rent & eviction protection

Is 2047-2049 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.

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.

Built 1909
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 2047-2049 Polk Street is a 2-story mixed-use building built in 1909, currently owned by 2047-2049 Polk Street LLC. The building has a complex history of occupancy and permit issues, most notably involving unauthorized residential units. The ground floor commercial space has been subject to multiple inspections and violations since 2014, with particular attention to an unauthorized residential unit created behind the salon. This situation has generated several citations and permit attempts for legalization or removal, including multiple cancelled permits in 2018 and a notable active violation through complaint #201481171 filed in 2014 that identified significant life safety concerns including inadequate foundation, lack of proper ventilation, and fire safety issues.

Recent history shows ongoing maintenance and safety concerns, with plumbing issues recurring throughout the years. A 2021 complaint documented mold testing due to water damage, and there have been multiple plumbing violations between 2013-2016 related to heating systems and water leaks. The building's system infrastructure has experienced various interventions, with permits for window replacement dating back to 2001, and multiple attempts to address permit violations regarding unauthorized construction. Recent 311 calls from 2022-2024 primarily concern exterior maintenance issues such as garbage management and sidewalk concerns, though these are not directly related to building habitability. The property has undergone several permit applications related to compliance with violation notices, including attempts to remove non-permitted first-floor additions and address unauthorized unit concerns, though many of these permits were ultimately cancelled or withdrawn.

Risk rating

How 2047-2049 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.

Out of 1125 buildings in this neighborhood, 742 are predicted to be safer.
