Rent & eviction protection

Is 345 Jones 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 1912
2 or more units
30 units
Property type
Multi-Family Residential
Zoning

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 1912
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 five-story, 30-unit apartment building at 345 Jones St, built in 1912 and currently owned by Warrior Rooster LLC, has undergone several significant safety system upgrades in recent years. Most notably, in 2023, the building received updates to its fire alarm system to comply with San Francisco Fire Code requirements, including the installation of low-frequency sounders in sleeping areas and an upgraded fire panel. A comparable fire safety improvement was completed in 2008 with the addition of five fire sprinkler heads in the garbage room across all floors. The building has experienced recurring elevator issues, with multiple complaints about non-functioning elevators, the most recent violation issued in November 2024.

Historical maintenance issues have included various concerns between 2002-2008 such as water damage, electrical problems, and general maintenance deficiencies, though most of these were resolved. There have been persistent concerns regarding building systems and safety equipment, as evidenced by multiple fire safety violations and complaints in 2023-2024 related to alarm systems, extinguishers, and exits. Recent fire incidents have been primarily related to non-threatening situations such as false alarms and system tests, with no reported civilian injuries. The building has maintained active engagement with fire safety requirements, evidenced by recent substantial investments in safety system upgrades, though there have been periodic lapses requiring citations and subsequent corrections.

Risk rating

How 345 Jones 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
49thpercentile

Out of 172 buildings in this neighborhood, 88 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 (ZIP code)

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