Initial analysis

The two-story, four-unit multi-family residential building at 159 Blake Street, owned by the Iribarren Family Living Trust and constructed in 1974, has experienced several significant maintenance and safety issues over the past two decades. Most recently, in 2024, the building was cited for multiple concerns including mold/mildew on walls and ceilings, window repairs needed for glazing seals and hardware, and roof deck repairs. Prior to this, in 2020, there were serious health-related complaints regarding old carpets causing respiratory issues, and in 2010, there was an incident involving flooding and water damage to personal belongings that required several months to resolve. The building's safety systems have also been a concern, with violations in 2004 related to fire extinguisher maintenance, smoke detectors, and emergency exits.

The property has had periodic maintenance work performed, including a $21,500 reroofing project in 2018, though a 1994 reroofing permit is still showing as expired in the records. In recent years, there have been multiple 311 calls regarding building conditions, including reports of broken doors/windows, inadequate building exterior maintenance, and some environmental health concerns that were transferred to appropriate authorities for investigation. The most recent documented fire incident involved a contained cooking fire with no civilian injuries, though the report doesn't specify a date. The building's record suggests ongoing maintenance challenges, particularly regarding interior surfaces and building systems, with the most pressing recent issues appearing to be related to mold, window integrity, and general building maintenance.

Risk rating

How 159 Blake 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.
