Initial analysis

The property at 3352-3354 21st Street is a three-unit, two-story multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood, built in 1900 and currently owned by Charles J. Smith. The building has undergone significant improvements over the years, with the most recent major upgrade being the installation of a 40-amp EV charger in May 2023. Previous substantial renovations include a complete HVAC installation for all three units in 2009, a comprehensive remodel of bathrooms and kitchens in 2007, and a roof replacement project in 2015. The property underwent notable address verification work in 2010, establishing additional unit designations for better identification.

The building's systems have generally been well-maintained, with proper permits secured for major work and timely responses to utility requirements, such as the gas line relocation in 2010 and electrical panel inspections in 2010. A significant renovation proposal to construct a three-story rear addition and add one dwelling unit was approved, though it's unclear from the records if this work was completed. The property has had minimal issues requiring intervention, with only one building complaint filed in July 2010 regarding unpermitted work on the sidewalk and driveway, which was quickly addressed. Recent municipal service calls in the vicinity primarily relate to street cleaning, garbage management, and parking issues, rather than building-specific concerns, indicating typical urban neighborhood dynamics with no major recurring maintenance or safety issues reported through official channels.

Risk rating

How 3352-3354 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
33th percentile

Out of 1278 buildings in this neighborhood, 856 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

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

12-Month severity forecast
No violation 39.0%
Moderate concern 18.4%
Severe concern 42.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
