Initial analysis

The three-story multi-family residential building at 1141-1147 Montgomery Street in Telegraph Hill, owned by Alan Owyang, is a 6-unit apartment building constructed in 1912. The property has undergone several significant maintenance and compliance updates over the years, most notably completing a mandatory soft-story seismic retrofit in 2015 at a cost of $60,000, which brought the building into compliance with San Francisco's seismic safety requirements. In 2005, the building was subject to multiple violations that were documented and subsequently abated by January 2006, including issues related to fire safety (such as fire proofing at the garage ceiling, fire extinguishers, garbage receptacles, and required sprinklers), structural elements (wood stairs and posts), and general safety requirements (missing handrails and building identification number). The building also received attention in 2013 when complaints were filed regarding unauthorized construction work, though these were marked as not active.

More recent history of the property shows several infrastructure and utility matters, including a sidewalk repair permit issued in 2004, a sewer leak addressed in 2000, and various street-related issues such as a collapsed sidewalk reported in 2024. The building's surroundings have been the subject of numerous parking-related complaints between 2022 and 2024, though these pertain to street parking issues rather than building-specific concerns. Two routine housing inspections from 2002 and 2005 were noted in the records, and while earlier violations were successfully resolved, there have been no significant building-specific violations or complaints documented in recent years, suggesting improved maintenance and compliance.

Risk rating

How 1141-1147 Montgomery 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
