Initial analysis

The two-story, four-unit multi-family residential building at 35 Walter Street in the Duboce Triangle neighborhood was constructed in 1925 and is currently owned by David & Marilyn Baum Revocable Trust. The property has a documented history of maintenance and repairs, with significant attention paid to addressing structural issues, particularly regarding wood decay. The most recent major infrastructure work occurred in 2018 with a sewer trap replacement, and prior to that, there were two notable dry rot repair projects in 2008 targeting the deck and exterior stairs, along with a complete reroofing in 2002 costing $15,000. A series of building violations were recorded in April 2008 that were promptly addressed by June 2008, including issues with drainage pipes, fire safety equipment, and gas utility requirements, indicating a period of active maintenance during that time. Historical records show earlier repairs for dry rot and termite issues in 1993, and the building has had routine inspections and plumbing-related complaints, including one in 1999 for unpermitted work.

The most recent activities around the property have been primarily related to street maintenance and parking enforcement, with several recent 311 calls in 2023-2024 concerning vehicles blocking driveways. There were also some general cleaning issues reported and resolved in early 2024, including reports of loose garbage on the street. A flooding incident was reported in January 2023, which was addressed. The building's records show regular maintenance and compliance with building codes, with no active violations or safety concerns as of the latest available data. The property's history demonstrates ongoing investment in structural maintenance, particularly addressing wood decay and roofing issues, though the frequency of these repairs suggests continued vigilance is required in this area.

Risk rating

How 35 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
