Initial analysis

The 15-unit apartment building at 3232 21st St in the Inner Mission, owned by Tse Living Trust, has undergone several significant safety and maintenance improvements since its construction in 1922. Most recently, in March 2023, repairs were completed to the garage and boiler room ceilings, along with removal of an unapproved roof cover (cost: $1,500). A major fire safety upgrade was completed in 2022-2024, including the installation of a new fire alarm system (cost: $25,200) and additional fire safety equipment such as exit signs and emergency lights. The building has also addressed structural safety concerns, having completed a mandatory seismic retrofit in 2014 (cost: $50,000) to comply with soft-story ordinance requirements.

The property has experienced several building inspections and violations over the years, with the most recent routine health and safety inspection in 2022-2023. Historical issues were addressed, including fire escape maintenance, fire extinguisher requirements, and various fire system upgrades, demonstrating ongoing attention to safety compliance. Fire department records show multiple responses to alarm activations and system checks between 2012-2022, but no significant fire incidents or civilian injuries have been recorded. Recent maintenance work includes a new Laars boiler installation (2024) and electrical system upgrades. While there have been recurring issues with sidewalk maintenance and occasional reports of debris, these have been addressed through appropriate municipal channels. The building's most concerning historical incident was a 2000 complaint involving sewage leaks and sanitation issues, which were promptly resolved.

Risk rating

How 3232 21St 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

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 8.5%
Moderate concern 80.3%
Severe concern 11.2%
