Rent & eviction protection

Is 1617-1625 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 before 1979
Built 1907
2 or more units

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 1907
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 45-unit multi-family residential building at 1617-1625 Polk Street, owned by 1625 P LLC, has undergone several significant upgrades and faced various maintenance challenges since its construction in 1907. Most recently, in September 2023, a complaint was filed regarding mold issues in the building's entrance area, following earlier reports of accessibility concerns in 2019 when elevators and wheelchair ramps were reportedly non-functional despite the building's accessibility claims. The property has seen substantial safety improvements in recent years, including a voluntary structural strengthening permit filed in July 2024, switch to new electrical panels in June 2023, and comprehensive fire alarm system upgrades in 2020 that met current safety standards. The building underwent significant accessibility modifications in 2019, including door replacements and hardware upgrades, though some permits were filed citing technical infeasibility/hardship.

Historical issues include multiple violations for lead paint hazards in 2011, which were addressed, and various complaints about building maintenance from 2014-2017, including reports of mold, pest infestations, and garbage handling issues. The property's commercial space underwent conversion from office to chair massage center use in 2013, which later led to compliance concerns in 2018 regarding unauthorized partitions that required removal. Recent inspections and permit activity suggest ongoing investment in building safety and maintenance, with marked improvements in fire safety systems, electrical infrastructure, and building accessibility features. Recent 311 calls from 2024 primarily relate to street cleaning matters near the property, with no active building-related complaints on file since the 2023 mold report.

Risk rating

How 1617-1625 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
4thpercentile

Out of 1125 buildings in this neighborhood, 1080 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
