Initial analysis

The property at 825-827 Hayes Street is a two-unit, two-story multi-family residential building located in the Alamo Square neighborhood, constructed in 1890 and currently owned by the Robert Alonso 2013 Trust. The building has undergone several significant renovations between 2008 and 2012, with the most substantial work occurring during 2008-2009 when major updates were implemented across both units. These improvements included comprehensive bathroom and kitchen remodels in both units, featuring new fixtures, cabinets, and appliances; complete electrical system upgrades with new 200-amp service installations and subpanels; plumbing modifications including new house trap installations; and various other interior improvements such as sheetrock and lighting updates. A bathroom renovation permit from 2008 was notably canceled in 2009 but was successfully completed under a new electrical permit.

In recent years, the property has had minimal maintenance issues, with only four 311 calls recorded in 2020-2021, none of which were related to the building's condition or resident safety. These calls primarily concerned exterior issues such as illegal postings, noise, and street/sidewalk cleanliness matters that were promptly resolved by city agencies. The most recent building permit on record is from 2012 for bathroom and kitchen improvements, suggesting that there have been no major structural modifications or system upgrades required since that time. The comprehensive renovation work completed between 2008-2012, which included both units' bathrooms and kitchens, electrical systems, and plumbing infrastructure, indicates that the building received significant modernization during that period, though more recent regular maintenance history is limited.

Risk rating

How 825-827 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.
