Initial analysis

The two-unit residential building at 409 Vallejo Street in Telegraph Hill is a two-story flats/duplex structure built in 1906, currently owned by the Anderson Robert M Survivors Trust. The property has undergone several significant maintenance and improvement projects over the past several decades, including three window replacement initiatives (most recently filed in August 2020 for six visible windows on the front half of the house), a completed window replacement in 2008, a reroofing project in 2001, and an expired plywood siding installation permit from 1986. Of particular note, there was a tenant buyout recorded in June 2015, with two tenants receiving $27,422.

The building's recent history (2022-2024) has been marked by multiple 311 calls, primarily related to street cleaning and waste management issues in the immediate vicinity rather than directly impacting the building itself. These included reports of garbage and debris, waste on the street, and a sidewalk graffiti incident in August 2023. An August 2022 report of human or animal waste and a July 2020 report of a collapsed sidewalk were both investigated and resolved, with the sidewalk issue noted as normal wear with no defects found. The property's maintenance record shows regular efforts to address exterior upkeep, while the frequency of street cleaning and waste management calls suggests ongoing challenges in the immediate neighborhood environment.

Risk rating

How 409 Vallejo 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
71th percentile

Out of 684 buildings in this neighborhood, 198 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Estimated permit spend (past 7 years)

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

Permit rate, owner's portfolio

Per-building permit rate across the owner's portfolio.

12-Month severity forecast
No violation 85.5%
Moderate concern 11.0%
Severe concern 3.5%
