Initial analysis

The two-unit multi-family residential building at 1236 Silver Avenue in Portola, owned by Frank R. Jr. Champion, is a two-story flats and duplex structure built in 1910. The property has experienced several concerning maintenance issues, with multiple complaints filed in 2022 regarding significant habitability concerns including inoperative plumbing, lack of heat, pest infestations (insects/rodents), mold, and general disrepair such as broken tiles and old carpet. These complaints were documented between May and July 2022, with one particularly alarming report mentioning grass growing out of a bathtub and black mold in an upper unit. The building also faced violations in March 2022 for unauthorized window replacements, which were subsequently addressed through a permitted window replacement in April 2022.

The property's maintenance history shows some attention to basic upkeep, with completed permits for reroofing work in 1991, horizontal additions in 1991, and the aforementioned window replacement in 2022. Recent infrastructure concerns include an open service request from August 2024 for a missing side sewer vent cover. The building's grounds have been subject to various maintenance needs over the years, particularly regarding tree maintenance, with multiple reports between 2017 and 2024 documenting issues with overgrown trees and communication line interference. While there have been no recorded fire incidents or tenant buyouts at the address, the combination of habitability complaints and ongoing maintenance issues suggests a pattern of infrastructure and upkeep challenges that may affect resident comfort and safety.

Risk rating

How 1236 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.
