Initial analysis

The 6-unit, 2-story multi-family residential building at 3999 Noriega Street in the Outer Sunset, owned by Hoshiyama Family Trust and constructed in 1965, has experienced several significant maintenance and safety-related events over the past two decades. A noteworthy cluster of violations occurred in 2017-2018, when the property underwent multiple inspections and received several Notices of Violation (NOVs) requiring attention to various safety and maintenance issues, including the removal of combustible storage, electrical hazards, plumbing deficiencies, and fire safety concerns such as damaged paint presenting potential lead hazards. During this period, substantial repairs were completed, including reroofing (2017, $16,500), stucco siding replacement (2017, $8,500), and electrical system upgrades to improve code compliance.

More recent history includes a combustible materials complaint (2024) that was deemed to have "No Merit" upon investigation, and an earlier hoarding-related issue (2019) that resulted in a violation being issued. The building's maintenance record shows attention to basic infrastructure, with repairs to plumbing fixtures documented in 2018, though some permits related to these repairs were marked as expired. The property has experienced two fire-related incidents, including a carbon monoxide event and one false alarm, though no civilian injuries were reported in either case. Recent 311 calls from late 2024 indicate ongoing neighborhood concerns primarily related to parking issues and street maintenance, though these are not directly related to the building's condition or management.

Risk rating

How 3999 Noriega 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
19th percentile

Out of 632 buildings in this neighborhood, 512 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.

Neighborhood location

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

Building size

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

12-Month severity forecast
No violation 65.1%
Moderate concern 14.1%
Severe concern 20.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
