Initial analysis

The three-unit building at 86-88 Sanchez Street in Duboce Triangle, owned by Raul & Denise Arriaza, is a three-story flats and duplex structure built in 1900. The property has a documented history of maintenance issues in the early 2000s, with several building violations recorded in 2002 and 2007. These violations included problems with structural members, handrails, and fire safety concerns regarding combustible storage. All these violations were officially abated by November 2002. More recent improvements have been made to Unit 86 in 2008, where existing plaster in two bedrooms was replaced with new sheetrock and insulation. The building underwent a prescheduled routine housing inspection in 2011, which remains active. While there have been some minor fire-related incidents recorded, including two contained trash or rubbish fires and one malfunctioning smoke detector activation, none resulted in civilian injuries.

In the past two years, the property has experienced several maintenance and cleanliness issues in the surrounding area, with multiple reports of garbage, debris, and hazardous materials, including glass, on public property. The most recent permits show minimal activity, with only a street space permit issued in 2017 for $1.00. The building's current exterior condition may be subject to periodic scrutiny, as evidenced by the various 311 calls related to street cleaning and maintenance, though these typically pertain to public areas rather than the building itself. The management history includes involvement from Bernstein Realty in 2007 when a broken window pane issue was reported and resolved. The property has maintained compliance with housing inspections since addressing the 2002-2007 violations, though the status of the 2011 routine inspection remains listed as active in the housing system.

Risk rating

How 86-88 Sanchez 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 287 buildings in this neighborhood, 158 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.

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.

NOV rate, owner's portfolio

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

12-Month severity forecast
No violation 70.5%
Moderate concern 20.1%
Severe concern 9.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
