Initial analysis

The property at 3943 Mission Street is a two-story, four-unit multi-family residential building located in Bernal Heights, constructed in 1951 and currently owned by Barbara C Sabbadini. The building's maintenance history shows several significant improvements over the years, including a complete re-roofing project in 2000 (cost: $6,000), installation of 10 replacement windows in 1997, and an electrical upgrade in 2003 involving the installation of new grid steel conduit and a service termination box for underground electrical distribution.

The building underwent a routine safety inspection by Housing Inspection Services in 2015, and previously in 2010, with most notable violations occurring in February 2000, when multiple safety issues were documented including the need for fire extinguisher recharging, installation of self-closing devices at exterior doors, and the addition of smoke detectors at stairs. These violations were all addressed and abated by March 20, 2000. Recent maintenance concerns have primarily focused on sewer issues, with multiple reports of sewage back-ups from the 4-inch sewer vent between 2020 and 2024, including a notable incident in November 2024. The building has also experienced recurring parking enforcement issues, with several documented cases of blocked driveways between 2020 and 2022. Other external maintenance matters have included street pavement defects and garbage issues, though these are municipal rather than building-specific concerns.

Risk rating

How 3943 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
28th percentile

Out of 1276 buildings in this neighborhood, 919 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.

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 35.0%
Moderate concern 19.4%
Severe concern 45.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
