Initial analysis

Located in Bernal Heights, 3992-3996 Mission Street is a 2-story multi-family residential building owned by Hobson Trust 2002, containing 14 units and constructed in 1979. The property has undergone several significant upgrades to its fire safety systems in recent years, including a 2023 retrofit to addressable fire alarm systems, a 2021 wireless fire alarm system installation, and multiple fire alarm-related complaints and violations (most recently in 2023). There are currently multiple active violations from a November 2022 health and safety inspection, including issues with smoke enclosure doors, gas shutoff tools, structural maintenance, and water heater safety features that remain unresolved as of October 2023. The building's maintenance history shows regular improvements, such as a 2006 window replacement project (installing 59 vinyl windows), a 2011 storefront remodeling, and various plumbing and electrical upgrades, including a new furnace installation in 2012.

The property has experienced several incidents and complaints over the years, including unauthorized conversions and construction work in the early 2000s related to a garage-to-storefront conversion, and a 2007 complaint regarding garage conversion to a church use. Fire safety has been a recurring focus, with multiple fire system violations and alarms recorded between 2005 and 2023, though most issues have been promptly corrected once identified. The building's systems have received consistent attention, with recent improvements including low-frequency alarm horns installation in 2022, though the active 2022 violations suggest some ongoing maintenance challenges. The property has generated multiple 311 calls in recent months primarily related to street cleaning and debris issues, suggesting ongoing challenges with exterior maintenance.

Risk rating

How 3992-3996 Mission 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

Out of 1276 buildings in this neighborhood, 1238 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 9.2%
Moderate concern 33.8%
Severe concern 56.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
