Initial analysis

The 425-429 Mississippi Street property is a three-unit, three-story multi-family residential building located in Potrero Hill, constructed in 1904 and currently owned by Ma Shannon & Boudreau Steph. The building has undergone several significant improvements over the years, with the most recent major renovation occurring in 2021, which included comprehensive updates to two kitchens and two bathrooms across multiple units, along with the installation of new laundry facilities. This $74,000 renovation, completed in March 2021, also involved electrical upgrades including new plugs, lights, switches, and a subpanel. Prior improvements include a new roof installation in 2015 ($24,893) and the replacement of an important second means of egress in 2005 ($14,000), demonstrating attention to safety requirements.

The building has experienced some maintenance and safety issues over its history, including a notable carbon monoxide leak related to heater malfunction reported in 2011, though this was promptly addressed within two months. Earlier concerns were documented in the year 2000 regarding various safety requirements such as gas meter instructions and handrails, all of which were resolved by October 2000. The property's infrastructure has seen multiple system upgrades over the years, including a new water service installation in 2008 and a wall heater replacement in 2011. Recent external issues have been limited to non-structural matters, with two instances of sidewalk graffiti reported in late 2023, both of which were resolved through proper channels. A historical pattern of abandoned vehicle complaints in 2009, involving a blue Volkswagen Jetta, was also addressed through appropriate enforcement actions.

Risk rating

How 425-429 Mississippi 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.
