Initial analysis

The three-unit residential building at 40 Child Street in Telegraph Hill, owned by Dante and Mary Giosso Family, is a three-story flats and duplex structure constructed in 1906. The property has undergone several significant maintenance and infrastructure updates over the past decades, with the most recent major work being a $21,800 reroofing project completed in March 2023, and a sewer repair completed in February 2015. Previous important improvements include a sewer line and house trap replacement in December 2008, sidewalk-related work in both 2015 and 2008, and another reroofing in 1990. The building underwent routine housing inspections in 2000, 2004, and 2006, all of which were completed without noting any persistent concerns.

The property has experienced minimal emergency incidents, with three recorded fire department responses for non-fire related situations: smoke/odor removal, invalid assistance, and medical assistance, none of which resulted in civilian injuries. Recent activity around the building has primarily consisted of routine urban infrastructure issues, including several 311 calls regarding parking violations, pavement defects, and service requests between 2021 and 2024. Notable concerns in the immediate vicinity include illegal parking incidents in 2022 and 2024, and garbage/urine issues reported in August 2024. However, these external issues are urban neighborhood challenges rather than building-specific problems. The property's maintenance record shows regular upkeep, with significant systems such as roofing and plumbing having received appropriate attention when needed, as evidenced by multiple permits for maintenance work over the years.

Risk rating

How 40 Child 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
86th percentile

Out of 684 buildings in this neighborhood, 96 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Building age

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

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

12-Month severity forecast
No violation 73.8%
Moderate concern 12.1%
Severe concern 14.1%
