Initial analysis

The three-story, 14-unit multi-family residential building at 3910-3918 Fulton Street in the Central Richmond neighborhood, owned by Bonnie Birsinger Casassa, has undergone several significant safety improvements and maintenance work since its construction in 1923. Most recently, in 2024, the building completed a substantial fire alarm system upgrade to comply with 2022 San Francisco Fire Code requirements, including both fire alarm and electrical work costing over $86,000. The building's safety systems have been a focus of attention, with violations and corrections documented in recent years. In December 2023, a sleeping area requirement violation was issued but subsequently abated. Previous fire safety issues included problems with the sprinkler/standpipe systems in 2019 and 2020, blocked exits, and street numbering concerns in 2018, all of which were corrected. The building has seen regular infrastructure maintenance, including a new hot water boiler installation in 2023, plumbing upgrades in 2011, and earlier foundation reinforcement work in 1990. Historical building violations from the early 2000s primarily involved security requirements related to self-closing doors and fire safety issues with the fire escape drop ladder and alarm system, all of which were resolved. Recent 311 calls related to the property area have mainly concerned external maintenance issues like graffiti and street cleaning, while the building itself has had no documented fire incidents with civilian injuries, though there was one electrical wiring/equipment problem noted.

Risk rating

How 3910-3918 Fulton 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
4th percentile

Out of 2250 buildings in this neighborhood, 2160 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.

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 15.1%
Moderate concern 39.7%
Severe concern 45.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
