Initial analysis

This three-story multi-family residential building located at 123 Lyon St in the Haight Ashbury neighborhood, owned by Maksin Mikhail & Verba Viol, consists of two units and has undergone several significant renovations and maintenance work over the past decades. Most notably, in 2016, the building underwent substantial electrical improvements, including the installation of a new sub-panel for common areas and replacement of unapproved wiring, while also addressing kitchen wiring that had been performed without permits. A serious building violation was documented in June 2016 regarding a gravity furnace in the basement with a leaking CO flue, though this issue was resolved within eight days.

The property has a history of stairway maintenance, with repairs to rear stairs completed in 2015 (cost: $3,000) and earlier repairs to lower unit stairs in 1993. Windows were updated in 2013 with the replacement of five windows at the front and rear of the building (cost: $3,500). More recently, there has been a pattern of parking enforcement issues, with multiple citations issued between 2023 and 2024 for driveway blocking incidents, suggesting ongoing challenges with parking compliance in the area. The building underwent a condo conversion process which was approved, and there was a previous violation regarding illegal short-term rentals that was successfully resolved. Two interior remodel permits were submitted - one in 2016 for unit 123 #2 (upper unit) and another in 2018 for unit 123 #1 (lower unit) - though both were ultimately withdrawn or cancelled.

Risk rating

How 123 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.

Neighborhood percentile
94th percentile

Out of 581 buildings in this neighborhood, 35 are predicted to be safer.
