Initial analysis

The two-story multi-family residential building at 418-420 Mississippi Street in Potrero Hill, owned by the Anavy Family Trust, consists of three units and was constructed in 1900. The property has experienced several significant maintenance issues over the past years, with the most pressing concerns occurring between 2017 and 2018. During this period, the rear deck and stair repairs were addressed following a violation notice filed in January 2017 that documented structural problems and dry rot in the approximately 15ft x 20ft deck. The owners completed multiple repair projects including sistering of the brick foundation, back porch repairs, and deck repairs, all with associated permits in 2017. A plumbing permit from January 2018 indicates installation of a floor drain and trap primer, though this permit has since expired.

More recent maintenance concerns have focused on sewer infrastructure, with three service requests between 2022 and 2024 indicating issues with the side sewer vent cover and sewage backup. The building's exterior areas have also presented challenges, with multiple 311 calls regarding sidewalk defects (December 2022), hazardous materials (August 2021), and tree-related concerns (February 2020 and May 2021) suggesting ongoing infrastructure maintenance needs. The property underwent an electrical upgrade in 2004 with an underground conversion to a 100-amp termination enclosure in the garage, and the roof was addressed in 1998 though that permit is listed as expired. While the major structural issues from 2017 appear to have been addressed, the building continues to experience periodic maintenance needs, particularly regarding its exterior infrastructure and utilities.

Risk rating

How 418-420 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.

Neighborhood percentile

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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building size

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 52.5%
Moderate concern 28.5%
Severe concern 19.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
