Initial analysis

The 66 9th Street property, owned by Mercy Housing Calif Xxxiv, is a high-rise multi-family residential building constructed in 2011, consisting of 15 or more units. The building has experienced significant recent fire safety concerns, with multiple violations issued between 2023 and 2024, particularly regarding sprinkler/standpipe systems, alarm systems, and fire code compliance. Most notably, there are currently open violations from August 2024 related to doors/self-closers, sprinkler obstructions, fire pump certificate requirements, firefighter air system records, and high-rise inspection fees. The building's maintenance history shows recurring issues with the boiler system, with multiple complaints about permit renewals between 2017 and 2021, though these were eventually abated. The property underwent substantial construction work in its early years, including the installation of a fire alarm system, structural modifications, and plumbing upgrades, with several permits for street space usage throughout 2008-2010.

More recent plumbing maintenance indicates some attention to building systems, with boiler replacements recorded in 2013, 2016, and 2017. The building has also experienced various other incidents, including multiple alarm system activations (though none related to actual fires), carbon monoxide incidents, and medical assistance calls, all with no reported civilian injuries. While the building has been generally active in responding to permit requirements, the ongoing nature of the fire safety violations as of 2024 represents the most pressing current concern for the property. The surrounding area has experienced typical urban issues as evidenced by recent 311 calls, primarily regarding garbage and debris, but these external factors do not directly reflect on the building's internal conditions or management.

Risk rating

How 66 9Th 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.

Neighborhood percentile
