Initial analysis

The 4-unit, two-story multi-family residential building at 2733 Diamond Street in Glen Park, owned by Donohue-wong Family Trust, was constructed in 1961 and has undergone several significant improvements over the years. Most notably, in 2012, the property underwent a substantial laundry room renovation including the addition of a bathroom, storage, and utility closet, with all associated plumbing and electrical work completed. In 2010, Unit #2 received a comprehensive kitchen and bathroom upgrade, including new appliances, fixtures, and exhaust fan installations in Units 1 and 2. The building faced a major compliance issue in late 2009 when multiple violations were recorded regarding fire safety and building maintenance, including concerns about garbage receptacle placement, fire sprinkler systems, and general access for inspections. These violations were all resolved by March 2011 through various repairs and improvements.

Recent maintenance history shows attention to safety and infrastructure, with completed work including stairway repairs and roofing projects in 2005 and 1991, respectively. The property has experienced some ongoing external maintenance challenges, as evidenced by recent 311 calls in 2023 and 2024 regarding tree damage to windows and graffiti. There have also been recurring issues with sidewalk parking violations near the property, with multiple enforcement actions taken between 2023 and 2024. Recent structural and safety improvements have focused on maintaining building systems and addressing external infrastructure needs, though there are currently two open maintenance issues from 2023-2024 related to tree damage near the building. The property has a history of routine housing inspections dating back to 1998, with regular updates and maintenance suggesting active management of the building's systems and infrastructure.

Risk rating

How 2733 Diamond 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
