Initial analysis

The two-story, four-unit apartment building at 325-331 Parnassus Avenue, constructed in 1909, has undergone several significant maintenance and compliance projects over the years. Most recently, in August 2024, a reroofing project valued at $24,000 was permitted, demonstrating ongoing infrastructure investment. The building has faced multiple compliance challenges, particularly notable in 2003 when several violations were documented under a single complaint, including issues with weatherproofing, stair repairs, electrical wiring, fire safety, and garbage placement, though these were resolved by October 2017. In 2009, the property required handrail upgrades and exterior painting work to comply with a notice of violation, and there was a significant electrical service upgrade to 200-amp service for all units in 2005.

The building's history includes a 2008 complaint regarding unsanitary conditions (trash accumulation, odor, and pest issues) that was addressed within two months. More recent routine inspections in 2017 resulted in various findings, though all were subsequently abated. Safety notifications regarding lead paint handling were issued in 2009, as well as multiple fire safety violations that required resolution. The property has experienced recurring issues with driveway parking violations in 2024, with multiple citations issued for vehicles blocking access, particularly throughout May and June 2024. Recent months have also seen several reports of garbage and debris issues near the property that have been resolved by Recology. While the building has faced various maintenance and compliance issues over the years, the majority have been addressed and resolved, with significant investments being made in recent roofing work and electrical infrastructure.

Risk rating

How 325-331 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

Out of 526 buildings in this neighborhood, 389 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.

Building size

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

12-Month severity forecast
No violation 56.3%
Moderate concern 20.7%
Severe concern 23.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
