Initial analysis

The property at 445-447 Hayes Street is a two-story mixed-use building constructed in 1906, containing both residential and retail spaces, currently managed by the Howarth Slaker Family Trust. The building has undergone numerous significant improvements over the past several years, with the most substantial work occurring in 2018 when retail tenant improvements valued at $111,000 were completed, including new lighting, storage modifications, and electrical compliance work. A major safety upgrade was executed in 2017-2018 with the installation of a comprehensive fire sprinkler system throughout the building, though some associated permits were later canceled. The building has seen consistent maintenance and upgrades, including electrical system improvements (400-amp service upgrades), plumbing renovations (kitchen, bathroom, and laundry room remodels), and the attempted addition of a roof deck in 2017 (permit was ultimately canceled).

Recent records from late 2024 show multiple 311 calls related to garbage and debris issues near the property, with some incidents involving human waste, though most cases were resolved with no work needed. There are also current open cases for graffiti and a public health complaint from December 2024. The building experienced several fire safety inspections between 2008 and 2010, mostly related to combustible materials, but all issues were promptly corrected. Fire incident records show only false alarms and unintentional system activations, with no actual fires or injuries reported. The property has seen various planning applications over the years, including attempted changes for outdoor dining and a roof deck addition, though some were withdrawn or canceled.

Risk rating

How 445-447 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.
