Initial analysis

The property at 446-448 Clement Street in San Francisco's Inner Richmond neighborhood is a 2-story multi-family residential building with 2 units, constructed in 1904 and currently owned by Garry C. and Mee Woon Chan. The building has undergone various modifications over the years, with the most recent significant change being the installation of a business awning for "Able Medical Supplies and Equipment" in May 2024, costing $600.00. The property has a documented history of maintenance and upgrades, including a 2005 electrical installation of 10 lights, switches, and circuits, and a completed fire system installation for the kitchen in 1993. However, there have been notable concerns regarding tenant living conditions in the mid-1990s, including reports of pest infestations and heating issues, though these were marked as resolved.

More recently, there have been multiple 311 calls (over 20 in the past year) related to garbage and debris on the property's exterior, with the most recent calls occurring in January 2025. A significant building-related complaint was filed in April 2022 regarding a projecting sign not in planning compliance, which was still listed as open under planning records as of 2024. The building's plumbing history includes a sewage backup incident in 1998, and there were unpermitted structural concerns in 1995 regarding a wood shack in the rear yard. Two fire-related incidents were recorded - a false alarm and a smoke removal situation, neither resulting in civilian injuries. Recent building permits and maintenance records show ongoing attention to the property's commercial space needs, particularly for the ground-floor business operations.

Risk rating

How 446-448 Clement 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

Out of 1723 buildings in this neighborhood, 1068 are predicted to be safer.
