Initial analysis

The Nittolo Family Trust owns this two-story, four-unit multi-family residential building located at 186-188 15th Avenue in the Lake-Presidio neighborhood. Built in 1914, the property has undergone various maintenance and inspection activities over the years, with the most recent significant event being multiple permit renewals in June 2022 for completed work, covering inspections from 1998 through 2002. The building has a history of routine housing inspections by Housing Inspection Services in 1999, 2004, 2007, and 2010, all of which were resolved. In 2000, there was one complaint regarding unauthorized construction work in addition to kitchen and bathroom renovations, which was closed in 2010.

Recent records from 2021 to 2025 show some minor issues primarily related to street maintenance, including reports of parking violations on sidewalks (most recently in March 2023), a damaged tree situation in early 2021 that was monitored by DPW, and a Christmas tree disposal issue in January 2025. The building experienced one minor cooking-related fire incident, though it was confined to a container and resulted in no civilian injuries. A fee housing inventory adjustment was processed through the Rent Board in February 2024, updating the unit count and associated fees. There have been no serious safety concerns or major building violations in recent years, and all reported issues have been addressed through proper channels.

Risk rating

How 186-188 15Th 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
38th percentile

Out of 660 buildings in this neighborhood, 409 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.

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.

12-Month severity forecast
No violation 61.8%
Moderate concern 27.3%
Severe concern 11.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
