Rent & eviction protection

Is 311-321 Turk 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 1920

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.

15+ years since occupancy
Built 1920
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 14-unit, 3-story multi-family residential building at 311-321 Turk Street, currently owned by the Curry Senior Center, was constructed in 1920 and has undergone several significant renovations and faced various maintenance challenges throughout its history. Most notably, the building has experienced multiple water damage incidents, with repairs documented in 2014 (including window and cabinetry work in unit 6) and earlier in 2011. The property has received substantial safety upgrades, including the installation of a complete wet pipe fire sprinkler system ($50,000) and a fire alarm system ($10,000) in 2002, followed by additional fire safety improvements through 2024. Recent fire safety concerns have emerged, with multiple violations issued between 2023-2024 regarding alarm systems and sprinkler/standpipe systems, though some have been marked as "Condition Corrected."

The building has a documented history of maintenance and compliance issues, including three instances of no heat complaints in 2024 and routine safety inspections revealing various violations such as egress obstructions, fire escape maintenance issues, and the need for carbon monoxide alarms in 2016. Earlier maintenance problems from 1995-1997 included plumbing and drainage issues in multiple units. Recent 311 calls from January 2025 highlight ongoing concerns with garbage and debris around the property, though many were promptly resolved. The building's management has generally addressed violations within a reasonable timeframe, as evidenced by multiple cases marked as "Resolved" or "Condition Corrected." The property underwent significant improvements in the early 2000s, including a major basement renovation with new electrical, mechanical, and plumbing systems valued at $1.5 million, indicating substantial investment in infrastructure at that time.

Risk rating

How 311-321 Turk 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
86thpercentile

Out of 172 buildings in this neighborhood, 24 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.

Building size

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

Number of units

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

Property class

The assessor's property-class code, which correlates with building type and the violation rates the model expects. This code is grouped with other less-common classes.
