Initial analysis

The property at 1426-1430 Hayes Street is a two-story, four-unit multi-family residential building located in the Park North neighborhood and owned by Giampolo Boschetti. Built in 1900, this apartment building has undergone several significant improvements in recent months, most notably a comprehensive fire alarm system upgrade completed in October 2024 at a cost of $18,600, which included installing low frequency sounders in sleeping areas to meet current fire safety codes. Additional electrical work related to the fire alarm system modification was also completed in October 2024, along with the installation of a new stove circuit.

The building has a history of maintenance issues that were addressed in 2006, including multiple violations related to interior surfaces such as mold and mildew problems, damaged walls, floor coverings, and fire proofing requirements. These violations, along with concerns about lead-based paint, were all resolved by October 30, 2006. More recently, a fire code violation was documented and issued in November 2024, though no details were provided in the records. The property has experienced some external maintenance issues as evidenced by multiple 311 calls between 2016-2024, primarily related to street cleaning, graffiti removal, and illegal postings on nearby surfaces. Three historical complaints from 1998-1999 included issues such as garage exhaust problems and routine inspections, all of which were resolved.

Risk rating

How 1426-1430 Hayes 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
42th percentile

Out of 797 buildings in this neighborhood, 462 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

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 56.3%
Moderate concern 20.1%
Severe concern 23.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
