Initial analysis

The two-story, five-unit apartment building at 37-41 Walter Street in the Duboce Triangle, built in 1906 and currently owned by John M. Dempcy, has undergone several significant improvements and faced various maintenance challenges over recent years. In 2019, residents reported concerns about mold and leakage in a back room, including potential ceiling stability issues, though this complaint is now listed as not active. The building received notable upgrades in late 2017 with the installation of 15 new energy-efficient windows across multiple units, costing approximately $19,726. A series of building permits from March 2018 related to street space use were filed, though the specific nature of these permits is not detailed in the records.

The building has a history of addressing safety concerns, most notably in January 2008 when multiple violations were documented regarding fire safety equipment, combustible storage, and plumbing/electrical issues. These violations, which included requirements to recharge fire extinguishers and address various fire safety concerns, were all abated by February 12, 2008. The property has undergone regular housing inspections over the years, including routine inspections in 2000, 2008, and 2010, with all issues appearing to be resolved. Recent street activity around the building has generated multiple 311 calls between 2020 and 2024, primarily related to sidewalk cleaning, garbage debris, and parking issues, including a notable incident in November 2023 involving an unpermitted portable toilet blocking the sidewalk, which was resolved through official channels.

Risk rating

How 37-41 Walter 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
