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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 988 buildings in this neighborhood, 761 are predicted to be safer.

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.

12-Month severity forecast
No violation 60.8%
Moderate concern 14.1%
Severe concern 25.2%
