Initial analysis

The 2-unit residential building at 20 Blake Street, owned by Anthony Walker, is a two-story flats and duplex structure built in 1951 in the Jordan Park/Laurel Heights neighborhood. The most significant recent development is the issuance of comprehensive renovation permits in October 2024 for major improvements to both units, including remodeling of two kitchens and two bathrooms, along with associated electrical work for new outlets and lighting, with an estimated cost of $100,000. This project represents the most substantial upgrade to the property in recent years. The building's maintenance history shows a water heater replacement in 2014, though that permit has since expired.

The property has experienced recurring issues with illegal parking on the adjacent sidewalk, particularly in 2019, when multiple reports were filed (some resulting in citations) regarding various vehicles including a Toyota, a Ford, and a Mini. More recently, there was an unverified parking complaint in August 2024. The surrounding area has seen some sidewalk cleanliness issues, with two reports of loose garbage in 2019 and 2022, which were resolved by the Department of Public Works. Two abandoned vehicle complaints were filed in March 2012, though in each case, the vehicles were gone when authorities arrived for inspection. The extensive parking violations and sidewalk cleanliness issues, while not directly affecting the building's internal conditions, may be of interest to prospective tenants regarding their neighborhood environment.

Risk rating

How 20 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.
