Initial analysis

The two-unit residential building at 44-46 Parnassus Avenue is a 2-story flats and duplex structure built in 1900, currently owned by the Valdez Tito C Estate. The property's maintenance history shows attention to structural integrity, with significant work performed in both 1986 and 2005, including dry rot repairs and termite treatment in 2005 (cost: $2,500), along with foundation work in the basement area completed in 1986. A garage conversion project proposed in 1986 was ultimately cancelled.

The building's immediate vicinity has experienced regular street maintenance issues, with multiple reports of garbage, debris, and general cleaning needs between 2020 and 2024, including a recent December 2024 report of abandoned furniture. The area has also been affected by occasional noise disturbances, with the most recent being a resolved noise complaint during a major event in August 2024, and there have been several parking-related incidents, including illegal parking in 2022 and a driveway blockage in 2020 that resulted in a citation. While these external factors generally relate to the neighborhood rather than the building itself, they represent ongoing environmental considerations for the property.

Risk rating

How 44-46 Parnassus 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
56th percentile

Out of 526 buildings in this neighborhood, 231 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.

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 71.9%
Moderate concern 16.2%
Severe concern 11.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
