Initial analysis

The property at 81 Blake Street is a single-story, two-unit multi-family residential building located in the Jordan Park/Laurel Heights neighborhood, owned by Steven H D Chan and built in 1940. The building has undergone several maintenance and improvement projects, with the most recent being an $8,500 exterior siding repair in November 2024. Previous improvements include a garage door replacement in 2018. A significant plumbing incident occurred in May 2002 when the curb house trap became clogged, resulting in a sewage overflow, though this was resolved by June 2002. More recently, the property experienced a fire alarm system violation in July 2024, which was issued and subsequently abated by August 2024.

The building's recent history shows multiple incidents requiring municipal intervention, particularly in late 2024, with several parking enforcement calls related to sidewalk parking violations, and various public works issues including graffiti removal and street cleaning matters. Notably, there was a tenant buyout recorded at 77 Blake Street in January 2020, totaling $30,000 for one tenant, though other buyout entries for this address appear incomplete in the records. The property has undergone some facade modifications over the years, including a documented replacement of non-original shingle siding with stucco, though the current use of the stucco is not specified in recent permits. The building compliance history shows attention to maintenance issues, particularly regarding security systems and emergency exits, with earlier violations in 2007 related to blocked exits that were corrected within three months.

Risk rating

How 81 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.
