Initial analysis

The two-unit multi-family residential building at 1035 Silver Avenue in Portola, owned by Colette Tsoi Yee, has undergone several significant improvements since 2019. The property, constructed in 1941 and classified as a Flat & Store with 4 units or less, received a substantial kitchen remodel in early 2019 valued at $20,000, followed by a complete electrical service upgrade to 200 amps in March 2019, and reroofing work completed in July 2019 at a cost of $9,000. This is not the building's first roof work; a reroofing project was also completed in 1996. The property has maintained its infrastructure with proper permits for significant upgrades, though the most recent work predates the current 311 calls by several years.

In late 2024, there was a notable increase in service requests related to the property's surroundings, with several calls regarding parking violations, including multiple cases of driveway blocking and one instance of sidewalk parking, resulting in citations. There are also ongoing issues with urban forestry, as evidenced by two open cases regarding tree maintenance (an overgrown tree and property damage complaint) from November 2024. Additional 311 calls in late 2024 have reported various street-level concerns, including a pavement defect that required no work, garbage and debris situations, and shared spaces utility access points, all of which have been officially resolved or abated. While these 311 calls primarily concern the property's exterior environment rather than the building itself, they do indicate some ongoing maintenance and enforcement issues in the immediate vicinity.

Risk rating

How 1035 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
18th percentile

Out of 255 buildings in this neighborhood, 209 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 43.8%
Moderate concern 25.7%
Severe concern 30.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
