Initial analysis

The two-unit residential building at 27-29 Lyon Street in Haight Ashbury, owned by Anthony B Phillips, is a two-story flats and duplex structure built in 1908. The property has undergone significant renovations and improvements over the past two decades, with the most substantial work occurring in 2015 when major bathroom additions and renovations were completed throughout both units, including the addition of multiple new bathrooms, showers, and associated plumbing infrastructure at a cost of over $85,000. This period also saw structural modifications to interior partitions, electrical system upgrades including new fixtures and panel relocations, and comprehensive plumbing work including sewer line replacement and new water lines installation, with all permits marked as complete.

The building's maintenance history shows consistent upkeep of bathroom facilities, with earlier renovations documented in 2005, 2009, and various electrical and plumbing improvements. A unit count verification in 2008 confirmed the two-unit status of the building. The property has experienced several parking-related incidents outside the building from 2018 through 2024, with six documented enforcement actions primarily involving illegal parking and sidewalk parking violations, though these are external to the building itself. A Department of Public Health Environmental Health inspection was requested in 2016, and there was one incident of waste cleanup required in 2009. A 2015 complaint about garbage receptacle management resulted in enforcement action, but specific details on its resolution are not provided in the records. Overall, the building appears to have received regular maintenance and upgrades, particularly focusing on modernizing bathroom facilities and associated infrastructure.

Risk rating

How 27-29 Lyon 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.
