Initial analysis

The property at 523 Chestnut Street in North Beach is a 3-story multi-family residential building constructed in 1907, containing 6 units and owned by Raul and Denise Arriaza. The building underwent significant renovations between 2016 and 2018, including the addition of a new dwelling unit on the ground floor completed in 2018, which involved extensive work including the installation of a comprehensive fire sprinkler system with 22 heads ($12,000) and associated sprinkler monitoring system ($3,500). Prior to this, three separate kitchen and bathroom remodeling projects were undertaken in late 2016, totaling approximately $63,000.

The building's renovation history includes proper permitting and installation of safety systems, such as a new 200-amp electrical service with 7 meters in 2017. There was one building violation in July 2017 related to improper containment of lead-based paint during construction, though this was promptly abated within days. Three tenant buyouts were recorded in 2016, with payments of $41,000 and $52,400 for units at 523 Chestnut Street and nearby Powell Street addresses. Recent activity in the area has primarily consisted of street cleaning and maintenance issues, with multiple reports of debris and graffiti between 2022-2024, though these do not directly relate to building conditions. The most recent records show routine graffiti and debris management, with no active building violations or complaints as of 2024. The only recorded emergency response to the building was a non-injury medical assist call.

Risk rating

How 523 Chestnut 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
29th percentile

Out of 362 buildings in this neighborhood, 257 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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.

12-Month severity forecast
No violation 69.0%
Moderate concern 24.2%
Severe concern 6.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
