Initial analysis

The two-unit residential building at 116-118 Seal Rock Drive in San Francisco's Outer Richmond neighborhood is a 2-story flats and duplex structure built in 1947, currently owned by William Wong. The building's maintenance history shows several significant infrastructure improvements over the years, most notably a comprehensive water main service upgrade completed in April 2011 for both units, and a repair to dry-rot damage on the exterior stairs in 1999. While there was an attempt to construct new fire-rated walls to separate the property storage room in 1999, this permit ultimately expired without completion.

The property has been subject to minimal 311 calls in recent years, with the most recent incidents occurring in late 2021, including a sidewalk parking violation that was promptly addressed by parking enforcement, and an instance of trash dumping in a park area that was transferred to the appropriate jurisdiction for resolution. The building's documented history suggests regular maintenance attention to critical systems, particularly water infrastructure, though the expired fire safety improvement permit from 1999 may warrant attention in terms of historical safety compliance.

Risk rating

How 116-118 Seal Rock Dr'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.
