Initial analysis

The 6-unit, 3-story apartment building at 70-74 Moss Street in San Francisco's South of Market neighborhood is a historic 1916 structure that has undergone significant safety improvements in recent years. Most notably, the building completed a mandatory soft-story retrofit in 2017 at a cost of $50,000, securing its seismic stability. The property has made substantial fire safety upgrades, including the installation of a comprehensive new fire alarm system in 2018 valued at $21,662, which features multiple smoke detectors, heat sensors, horn strobes, low-frequency sounders, and pull stations. The building's maintenance records indicate regular upkeep, with recent work including a 2021 replacement of a 40-gallon gas water heater for unit 74 and a sewer repair in 2018.

The building's history shows attention to addressing safety and maintenance issues as they arise. In 2017, the property underwent significant infrastructure improvements, including ductwork demolition, furnace replacement, and lateral sewer line replacement with cast iron piping. The building has experienced multiple fire alarm system activations over the years, all of which were determined to be unintentional or caused by system malfunction, with no civilian injuries reported in any incidents. While there were several building violations noted in 2003 and 2011 related to fire safety, security, and plumbing systems, these were all promptly addressed and abated. Recent 311 calls from 2024 primarily concerned external issues such as abandoned debris, parking violations, and graffiti, which were not directly related to building maintenance or safety.

Risk rating

How 70-74 Moss 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.
