Rent & eviction protection

Is 1100-1128 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 1917

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 55-unit, 4-story multi-family residential building at 1100-1128 Polk Street, owned by the John E Wai 1981 Living Trust, was built in 1917 and has undergone various renovations and faced recurring maintenance issues. Most notably, the building is currently experiencing significant elevator problems, with multiple tenant complaints since October 2024 indicating the elevator has been non-functional for nearly two years, directly impacting disabled access and resident convenience. Recent building safety concerns include a July 2024 violation related to sprinkler/standpipe systems and a September 2023 violation for missing documentation regarding fire safety equipment maintenance. The property has seen substantial interior renovations over the years, including kitchen and bathroom remodels in units 210, 304, and 316, roof replacement in 2018, and recent commercial space modifications including soundproofing insulation in 2019. Historical building violations from 2004-2005 included issues with lead paint hazards, plumbing, electrical systems, and an inoperative elevator, all of which were eventually resolved. Recent complaints also indicate concerns with the garbage disposal system, as management temporarily disabled garbage chutes in late 2024, forcing residents to use alternative disposal methods. The building's fire safety system has been the subject of multiple incidents and violations, though most fire-related emergencies recorded were for non-injury incidents such as gas leaks, electrical issues, and assist calls.

Risk rating

How 1100-1128 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
17thpercentile

Out of 448 buildings in this neighborhood, 372 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
