Initial analysis

The property at 340-342 Missouri Street is a multi-family residential building located in Potrero Hill, owned by Carole Mears and Peter D. This two-unit, two-story structure, built in 1910, has undergone significant improvements over the past several years. Most notably, in 2020-2021, there were substantial renovations to Unit 340, including kitchen and bathroom remodels, electrical system upgrades, and the installation of a new furnace. The building's electrical infrastructure has been notably upgraded in 2023-2024, with the installation of a new 400-amp service, multiple sub-panel replacements, and a solar photovoltaic system. Recent building maintenance includes a completed reroofing project in 2021 costing $8,000.

The property has experienced several notable issues in recent years that may affect resident quality of life. Two sidewalk defect cases were reported in March 2022, and there is an open case regarding tree roots damaging the sidewalk from May 2022. There have also been multiple parking enforcement calls in recent years, suggesting ongoing parking challenges in the area. A significant planning record from 2021 noted concerns about potentially unpermitted unit modifications and dwelling unit relocation, though this appears to have been addressed through subsequent permits requiring restoration of unit separation and full kitchen installation. The building has also experienced some minor fire incidents, including one contained cooking fire, though no civilian injuries were reported.

Risk rating

How 340-342 Missouri 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
98th percentile

Out of 726 buildings in this neighborhood, 15 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Neighborhood (ZIP code)

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

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 89.4%
Moderate concern 8.8%
Severe concern 1.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
