Initial analysis

The property at 224 Silliman Street is a two-unit multi-family residential building located in the Portola neighborhood, constructed in 1904 and classified as a Flats & Duplex structure. The building's maintenance history shows significant activity in 2018 when multiple violations were documented, including issues with interior surfaces (paint), plumbing shut-offs, sanitation, and the need for smoke and carbon monoxide alarms, though all these violations were abated by April 4, 2018. A roof leak was reported in February 2018, which appears to have prompted these inspections. The building had undergone concrete, fence, and stair repairs, along with door and window replacements in 1990, suggesting some level of structural maintenance.

More recently, the property has experienced several parking-related issues on Silliman Street, with multiple complaints between 2022 and 2024 regarding vehicles blocking driveways and parking on sidewalks. These incidents resulted in various enforcement actions, including citations. The most significant recent event was a tenant buyout in August 2022, involving three tenants and a payout of $80,000, indicating a substantial change in occupancy status. The building's most recent maintenance-related interactions with city agencies have been minimal, with only one sewer-related service request in September 2024 that was resolved with no defects found.

Risk rating

How 224 Silliman 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
