Initial analysis

The two-unit multi-family residential building at 377-379 Hayes Street, built in 1912 and including a commercial storefront, has undergone several significant modifications and faced various regulatory challenges in recent years. Most notably, in 2023, the property began work to comply with the Accessible Building Entrance Program, including hardware modifications to meet accessibility standards. The building has experienced multiple fire safety inspections and violations, particularly in 2023 when multiple fire code violations were issued regarding place of assembly permits and LP gas use, though these violations were subsequently rescinded. There have been recurring issues with waste management in the vicinity, with multiple 311 calls in late 2024 regarding garbage and debris, though most of these cases were resolved without the need for further action.

The property's history includes substantial structural work in the 1990s, with projects such as reroofing, mud sill repairs, and a horizontal addition, as well as more recent issues including unauthorized signage installation in 2022. The building underwent underpinning work in 2007 due to adjacent construction, indicating attention to structural stability. Recent fire safety inspections in 2024 have shown improved compliance, with no serious violations noted. The building's dual-use nature (residential and commercial) is reflected in the various permits and complaints, with the commercial section frequently generating code compliance concerns, particularly regarding signage and fire safety requirements.

Risk rating

How 377-379 Hayes 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 C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
