Initial analysis

The three-unit multi-family residential building at 925-931 Vallejo Street in Russian Hill, built in 1909 and currently owned by the Wayland Chin Revoc Tr, has experienced several significant maintenance and safety-related events over its history. The building underwent critical plumbing infrastructure improvements in 2012 with the replacement of the sewer line and installation of a house trap, following earlier plumbing issues including a 2005 incident involving a cracked sewer pipe and basement water problems. A series of building violations were documented in 2009-2010, including gas utility safety concerns (missing shutoff tool and instructional diagram), fire safety issues (egress obstructions), and a water-related problem that was ultimately addressed. Historical records show attempts to address various building code compliance issues, such as a 1986 permit to bring the property into code as per Dahi.

Recent developments include recognized service needs for the property, with routine inspections by Housing Inspection Services continuing into 2017, though this specific inspection remains marked as active. The building has experienced various exterior maintenance and security concerns typical for its location, as evidenced by multiple 311 calls between 2021-2024 regarding parking enforcement, illegal postings, and abandoned vehicle issues. The property underwent some unauthorized modifications, as indicated by planning records noting an unpermitted enclosure of the front porch with new roof, siding, and windows. A single reported incident of smoke or odor removal was recorded in the fire incident database, though no civilian injuries were reported.

Risk rating

How 925-931 Vallejo 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.
