Initial analysis

The two-story, 10-unit multi-family residential building at 447 34th Avenue in the Outer Richmond, owned by Pitto Angelo P, has undergone several significant improvements since its construction in 1962. Most notably, the building completed a mandatory soft-story seismic retrofit in 2014 with a cost of $110,000, bringing it into compliance with San Francisco's safety requirements and earning a Certificate of Final Completion. Other major maintenance work included the installation of a new furnace in 2013, fire repairs in 1983, and historical improvements such as window replacements in 1994 and reroofing in 1996, though the latter two permits have since expired.

The building's recent history shows relatively few internal issues, with only two routine housing inspections recorded - one in 2011 (which was resolved the same day) and another from 2002 that remains active. The property has experienced some external challenges, primarily related to parking violations, with three documented incidents between 2019 and 2020 involving vehicles blocking sidewalks or bicycle lanes. More recent activity in 2024 has focused on street-level maintenance, including reports of abandoned electronics and other debris, which were all resolved promptly. The building has had three false fire alarms recorded, though fortunately, none resulted in civilian injuries or significant incidents.

Risk rating

How 447 34Th 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
3th percentile

Out of 1040 buildings in this neighborhood, 1009 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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.

12-Month severity forecast
No violation 27.6%
Moderate concern 56.1%
Severe concern 16.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
