Initial analysis

The 12-unit, 2-story multi-family residential building at 327-335 23rd Avenue in the Central Richmond neighborhood, owned by Walter J Strach Jr and built in 1967, has experienced several significant maintenance and safety issues over the past few years. Most notably, recent concerns include an August 2023 incident involving water intrusion that persisted for two months, which coincided with violations regarding egress obstruction from fire escape, a damaged ceiling, and water-related building issues. The property has undergone various structural modifications, including a $10,000 structural beam replacement at the rear garage opening in 2020, and previously in 2019, work was done to replace siding and address structural elements, which generated some controversy over permitting scope.

The building has a history of maintenance and safety compliance issues, particularly from 2003 when multiple violations were recorded regarding fire safety equipment and gas utility requirements, all of which were subsequently abated. More recent fire safety concerns include blocked exits and alarm system issues in early 2023, though these were corrected promptly. The property appears to have ongoing maintenance challenges, as evidenced by persistent water-related issues and periodic structural repairs. Recent building works include a scheduled re-roofing project valued at $22,050, indicating ongoing infrastructural upkeep. The building's location has experienced typical urban neighborhood issues as reflected in 311 calls, primarily relating to parking violations and street cleaning matters, though these are external to the building's management.

Risk rating

How 327-335 23Rd Ave'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.
