Rent & eviction protection

Is 1447 Chestnut 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 1926
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.

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 three-story, 12-unit multi-family residential building at 1447 Chestnut Street in the Marina, built in 1926, has undergone several significant safety and maintenance improvements over the years, with the most recent being a comprehensive fire alarm system upgrade completed in October 2024, costing approximately $35,800. The building has successfully completed its mandatory soft-story retrofit as a Tier 3 property, demonstrating compliance with seismic safety requirements. Major improvements include a 2017 soft-story retrofit costing $105,000, 2016 stair repairs following a violation notice, and electrical system upgrades in 2003 to 175-amp service with 13-meter sockets. The property underwent routine safety inspections in 1999, 2006, and 2016, addressing various issues including gate manual release systems and carbon monoxide alarm installations, all of which were subsequently resolved.

Recent building activities have primarily focused on life safety systems, with the most substantial work being the 2024 fire alarm system upgrade that included new low-frequency sounders in sleeping areas to meet current codes. The building had documented fire safety concerns in 2018 regarding hazardous materials and sprinkler systems, though these violations were abated as of May 2018. Regular maintenance has been performed throughout the building's history, including termite repairs in 1995, window and bathroom improvements in the late 1980s, and various routine inspections. The property has experienced recurring issues with driveway blockage, as evidenced by multiple parking enforcement calls in recent years, though these are external to the building's internal systems and safety features. Recent service requests have primarily involved waste collection and public works matters, which have all been resolved promptly.

Risk rating

How 1447 Chestnut 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
14thpercentile

Out of 988 buildings in this neighborhood, 850 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
