Initial analysis

The two-unit residential building at 146-148 Seal Rock Drive, located in San Francisco's Outer Richmond neighborhood, is a two-story flats and duplex structure built in 1947 and currently owned by the Frances R Stroh Revocable Trust. The property has undergone several significant renovations and improvements, with the most substantial work occurring in 2015 when the building underwent exterior and bathroom renovations costing $56,000, including stucco removal and replacement, window upgrades, and comprehensive bathroom remodels on both floors. This work was accompanied by necessary permits to correct unit count documentation. Earlier improvements include a 2008 kitchen remodel at Unit 146 valued at $15,000, which included electrical upgrades, gas line modifications, and new cabinetry installation, as well as a 2006 roofing project that involved clay tile crown installation and exterior painting.

The building has experienced minimal issues since 2015, though there was one building complaint filed in March 2015 regarding work scope and debris containment during the aforementioned renovation, which is currently listed as not active. The property’s utilities have been maintained with furnace replacements recorded in 2010, though these permits show as expired. Recent minor incidents include parking violations and illegal posting complaints from 2017 and 2018, which were resolved through normal city channels. Planning records confirm that major exterior work was conducted with proper adherence to architectural guidelines, including stucco replacement and window upgrades, with no reported code violations or expansion requests. The building's maintenance history shows regular upkeep, particularly of its exterior and essential systems, with all recent major improvements completed through proper permitting processes.

Risk rating

How 146-148 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.
