Initial analysis

The 6-unit, 3-story multi-family residential building at 1317-1321 Masonic Ave in the Haight Ashbury neighborhood, owned by Agnes And Tony Yeh LLC, has undergone several significant infrastructure improvements and faced various regulatory requirements since its construction in 1906. The most critical recent work involved a mandatory seismic retrofit soft-story improvement, which was initially permitted in 2017 but encountered multiple permit extensions and issues before finally being completed in late 2023, achieving compliance with San Francisco's Tier 3 requirements and receiving a Certificate of Final Completion. The building faced multiple code violations in 2003 regarding fire safety, security, and structural maintenance, including issues with fire extinguishers, the central alarm system, combustible storage, exterior door security, and a rear deck/porch repair requirement, though all these violations were abated by March 2003.

Recent maintenance work includes a 2023 boiler removal and historical records show a console heater replacement in 2014. The property has experienced routine housing inspections, with particular attention to fire safety systems, and has had several 311 calls in recent years primarily related to street cleaning and maintenance issues in the immediate vicinity, including reports of medical waste and garbage. While the most recent fire incident was an unintentional alarm system activation in 2021 with no injuries, the building's fire safety systems have required ongoing attention, as evidenced by historical violations and a 2021 fire complaint regarding alarm systems that was promptly corrected. The property has also been subject to regular tree maintenance requirements, with multiple reports filed between 2017 and 2024, indicating ongoing attention to the building's landscaping needs.

Risk rating

How 1317-1321 Masonic Ave'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.
