Initial analysis

The property at 4142-4144 Mission Street, located in the Mission Terrace neighborhood, is a 1900-built multi-family residential building classified as Flats & Duplex, currently under the ownership of David W. Foon. The building's maintenance history includes several sidewalk repairs and a reroofing project from 2000 and 1993 respectively, though all these permits have since expired. A routine safety inspection in 2015 and annual inspections in 2009 and 2000 have been conducted by Housing Inspection Services, with all issues being resolved. Notably, in April 2000, the building received multiple violations concerning fire safety (missing fire extinguishers) and security (self-closing exterior doors), all of which were abated by May 2000.

The building experienced some concerning issues in 2014, with two hoarding complaints filed in February and March, though one was found to have no merit while the other was corrected promptly. There were also two fire-related service calls recorded, though no civilian injuries were reported in connection with these incidents. The property has had recurring issues with sidewalk cleanliness, as evidenced by multiple 311 calls for loose garbage in 2021, and occasional illegal parking problems in 2022. Most recently, in November 2021, there was a construction equipment-related parking issue that was resolved. The building's fire alarm system was found to have issues in April 2009, which were corrected promptly the following day. Additionally, there was a brief period in 2001 when windows were reported to be covered with curtains and blinds, though this was addressed according to planning records. There have been no active violations or serious incidents recorded in recent years, suggesting improved maintenance and compliance with building codes.

Risk rating

How 4142-4144 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.
