Initial analysis

311 Joost Ave is a two-story, four-unit multi-family residential building located in the Sunnyside neighborhood, owned by Ray E. and Irene W. Tisell, and constructed in 1905. The building's maintenance history shows several significant repairs and improvements, including a complete reroofing project in 2016 costing $7,100, bathroom installation in an existing garage in 2012, and major structural work such as pier, post, and beam replacement in 1985. The building underwent routine housing inspections in 1999, 2000, 2003, and 2008, during which violations were noted in 2000 regarding a dilapidated window frame and the need for a one-hour rated wall with closer, though these issues were abated by November 2000.

Recent maintenance and safety history shows a mix of building and street-related issues in the vicinity, with the most notable recent incidents being a sewage backup discharge from a side sewer vent in December 2024 and multiple curb or ramp defect reports in the same month. The building has experienced some environmental health issues, as evidenced by a current open public health inspection from January 2025. Although there was one fire complaint in March 2016 regarding combustible materials, it was found to have no merit. The building's surrounding area has seen various municipal service calls in recent months, primarily related to street conditions and maintenance issues. The property appears to have addressed historical violations and has undergone regular maintenance, with the most recent significant building-related work being the 2016 roofing project.

Risk rating

How 311 Joost 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.

Neighborhood percentile
