Initial analysis

The two-unit residential building at 478 30th Street in Noe Valley is a two-story flats and duplex structure built in 1908, currently owned by John D Moriarty 2012 Revocable Trust. The building's documented maintenance history shows two significant repairs: a $1,000 deck and handrail repair completed in 2009, and a reroofing project from 1995, though this permit is listed as expired.

The property has experienced several local issues in recent years, most notably a pattern of parking violations near the property, with three documented instances of vehicles parking on the sidewalk between late 2022 and 2024, including two separate incidents involving a Toyota RAV4 with the same license plate. More recently, there are two open cases from 2024 involving a damaged tree from vandalism and a closed case involving sidewalk parking that resulted in a citation. Earlier incidents include cases of illegal postings (March 2023), street graffiti (March 2023 and October 2022), and another damaged tree report from October 2022. While many of these issues have been resolved through appropriate channels, the recurring nature of parking violations and the recent tree vandalism warrant attention to ongoing neighborhood concerns, particularly regarding property borders and maintenance of public spaces.

Risk rating

How 478 30Th 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

Out of 1879 buildings in this neighborhood, 1221 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.

Neighborhood location

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

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

Building age

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

12-Month severity forecast
No violation 60.7%
Moderate concern 25.7%
Severe concern 13.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
