Initial analysis

The two-unit residential building at 93-95 Stanyan Blvd in San Francisco's Lone Mountain neighborhood is a two-story flats and duplex structure built in 1939, currently owned by Michael David Mah since a 2017 revocable trust transfer. The property has undergone significant maintenance and upgrades over the past decade, including window replacements, roofing work, and various exterior improvements. Most recent improvements include a 2019 window replacement installation (not visible from the street), and in 2016, both units received re-roofing work. The building has seen consistent maintenance of its external features, with previous projects including French door replacement (2013), vinyl siding installation (2013), and multiple window upgrades (notably a 2011 project replacing 9 street-visible windows). The property's electrical systems were upgraded in 2003 with significant interior work done in the kitchen, living room, and dining areas.

The building's maintenance history reveals attention to both interior and exterior upkeep, though there was a notable issue in 1999 when a roof leak resulted in mold/mildew concerns and property damage, which was reportedly resolved within a few months. More recently, there have been multiple 311 calls in the surrounding area (2021-2024) primarily related to graffiti, illegal postings, and street maintenance issues, though these appear to be exterior to the building itself and were generally resolved by city services. The only recorded emergency incident was a gas leak situation (412) with no civilian injuries noted. The property's documented permit history suggests regular upkeep and modernization efforts, with no recent safety or habitability concerns reported through building complaints or housing inspections.

Risk rating

How 93-95 Stanyan Blvd'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.
