Initial analysis

1453 Silver Avenue is a three-story multi-family residential building located in San Francisco's Portola neighborhood, consisting of two units and constructed in 2001. The property, owned by Edward and Marylou Zaparolli, was originally proposed through a planning application that sought to build a two-family dwelling with an exemption from the minimum rear yard requirements specified in Section 134 of the Planning Code. This initial application was submitted in 2000 and ultimately received approval, allowing the construction of the duplex despite the rear yard variance request. The building, classified as Flats & Duplex, has demonstrated compliance with all planning requirements since its construction and continues to operate as originally intended, with no recorded violations or safety concerns on file.

Risk rating

How 1453 Silver Ave'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 255 buildings in this neighborhood, 46 are predicted to be safer.
