55 Polk St

Van Ness/ Civic Center, SF 94102 0814019 31 units · 4 fl · 1917

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 55 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
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 31-unit, 4-story multi-family residential building at 55 Polk Street, built in 1917 and currently owned by Jnl Polk Lp, has experienced several significant building and fire safety issues in recent years. Most notably, there is currently an active cluster of fire safety violations as of 2024, including issues with the high-rise sprinkler system, standpipe maintenance, fire door functionality, alarm system maintenance, and sleeping area requirements. The building has undergone various improvements and repairs over the years, including a 2023 fire alarm system upgrade costing $36,600 to comply with current fire code requirements. In 2018, unit 104 underwent a kitchen and bathroom remodel, though this work was preceded by a complaint regarding construction damage to a neighboring unit. The property has faced multiple fire safety concerns throughout 2023-2024, with several violations being issued and subsequently corrected but others remaining open as of late 2024.

Historical records show some recurring maintenance and safety pattern, including the need to restore historical fire exit paths in 2016 and various plumbing and electrical updates. The building experienced multiple violations in 2009 related to water damage, interior surface maintenance, and smoke detector functionality, though these were abated by 2011. More recent history (2016-2024) indicates ongoing fire alarm system issues, with multiple violations and malfunctioning alarm system activations being recorded. While many repair and improvement projects have been successfully completed, including kitchen renovations and various system upgrades, the persistent nature of fire safety violations suggests continuing challenges with maintaining current safety standards. Recent fire violations (as of 2024) specifically cite issues with the alarm system, sleeping area requirements, standpipe maintenance, and sprinkler system compliance, indicating these areas require ongoing attention and maintenance.

Risk rating

How 55 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
62ndpercentile

Out of 85 buildings in this neighborhood, 32 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

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 (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
