Initial analysis

The three-unit multi-family residential building at 3758-3762 21st Street, owned by Matthew Putnam, is a three-story TIC building constructed in 1907 in the Eureka Valley/Dolores Heights neighborhood. The property underwent significant renovations in early 2014, including comprehensive updates to all units with new electrical systems (complete with 200-amp service and full kitchen/bathroom upgrades), plumbing improvements (including six bathrooms, three kitchens, radiant heating, and appliance installations), and structural work (basement wall repairs, staircase renovations, and window replacements). The building has experienced some maintenance issues in recent months, including two sewage discharge incidents from the side sewer vent in November 2024, while ongoing concerns include a damaged tree with lifted sidewalk roots (open status since October 2024). A fire alarm system issue was reported in September 2021 but was resolved by April 2022, and there was one documented smoke detector activation due to malfunction. The building's history includes a routine inspection in 2007 that identified various safety concerns (such as stair repairs and gas utility shutoff requirements), all of which were promptly addressed and abated by March 2007.

Risk rating

How 3758-3762 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
31th percentile

Out of 1278 buildings in this neighborhood, 882 are predicted to be safer.

Model explanation

What's driving this score

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 60.4%
Moderate concern 28.4%
Severe concern 11.1%
