Initial analysis

The three-unit multi-family residential building at 3731 16th Street in Corona Heights, owned by Joseph N. Granese Jr, was constructed in 1923 and consists of two stories. The property has undergone several significant renovations and faced multiple compliance issues over its history, with the most substantial recent work occurring in 2021 when the first-floor deck was rebuilt, including new beams, joists, and stairs, following a notice of violation. The building experienced a cluster of violations in June 2021, all of which were abated by November 2021, including issues with hazardous mechanical equipment, stair repairs, deck condition, seismic bracing for water heaters, door handles, and various safety requirements such as gas meter instructions and tool provision.

Earlier improvements include a 2018 reroofing project, a 2005 electrical system upgrade including underground service conversion, and plumbing work in 2016 involving sewer and house trap replacement. The building has undergone periodic routine inspections by Housing Inspection Services in 2002, 2009, and most recently in 2021, suggesting regular oversight of building conditions. Recent maintenance and safety concerns have been addressed, though there have been ongoing issues in the surrounding area as evidenced by multiple 311 calls in 2024 regarding sidewalk cleaning, manhole issues, and encampments. The property's documented history shows a pattern of addressing violations and maintaining essential systems, with most recent permits focusing on safety and structural integrity improvements.

Risk rating

How 3731 16Th 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.
