Initial analysis

1145 Hayes Street is a three-story, 15-unit multi-family residential building constructed in 1906 in the Alamo Square neighborhood, currently owned by HVH Hayes Street LLC. The building has undergone several significant improvements in recent years, including a comprehensive fire alarm system upgrade in 2024 valued at $71,100 to comply with current safety codes, and completion of a mandatory soft-story seismic retrofit in 2016. Between 2018 and 2021, multiple units received substantial renovations including kitchen and bathroom remodels, window replacements, and various infrastructure upgrades such as electrical panel installations and plumbing improvements.

Recent documented resident concerns include a 2024 complaint about irregular heating, and a 2022 report of black mold in a kitchen sink allegedly related to leaks. The building has experienced recurring water-related issues, particularly concerning Unit 6, including chronic leaks documented in 2013. Historical records show multiple renovation-related complaints in 2006 regarding unpermitted work in several units, which were subsequently resolved. The property has maintained active compliance with building codes, having completed all required seismic retrofitting and safety upgrades, though some maintenance issues have persisted, such as the recent heating complaint and historical water damage problems. Regular maintenance and improvements have been documented through multiple work permits, including significant structural and safety upgrades.

Risk rating

How 1145 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 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.
