Rent & eviction protection

Is 1721 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 1964
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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

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

1721 Chestnut Street is a 12-unit, three-story multi-family residential building constructed in 1964, currently owned by Mehan Properties LLC. The building has undergone significant safety improvements in recent years, most notably completing mandatory soft-story retrofits in 2019 (with an additional revision) at a total cost of $115,000, achieving compliance with San Francisco's seismic safety requirements. The building's fire safety systems have received attention, with a new fire alarm system modification and low-frequency sounder installation currently in process (August 2024), though a recent fire violation was issued in January 2024 regarding alarm system maintenance.

The building has experienced several maintenance and safety issues over its history. In 2017, multiple violations were issued and subsequently abated regarding interior surfaces, water damage, lead paint concerns, and various safety systems including carbon monoxide detectors, fire escape maintenance, and smoke enclosure doors. A 2014 complaint about inadequate hot water service due to an undersized replacement water heater was documented. More recently, the building has had visible maintenance issues including graffiti (2023) and a collapsed sidewalk (2023) nearby. The property has a history of plumbing and electrical work, with records showing water heater replacement in 2014 and the most recent gas line work completed in March 2024. While the building has faced various challenges, most violations and complaints have been resolved through appropriate corrective actions, and major safety systems are being actively maintained and updated.

Risk rating

How 1721 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
22ndpercentile

Out of 988 buildings in this neighborhood, 771 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.
