Initial analysis

The 6-unit, 2-story multi-family residential building at 561 Arguello Blvd in the Inner Richmond, managed by Mah Trust, has undergone several significant improvements since its construction in 1967. Most notably, in late 2023, Unit #6 received extensive renovations including new kitchen cabinets, countertops, flooring, lighting improvements, and comprehensive bathroom updates, with associated plumbing and electrical work completed under permits totaling approximately $80,400. The building has also addressed major structural requirements, completing a mandatory soft-story retrofit in 2019 (costing $85,000) with follow-up structural revisions, demonstrating compliance with seismic safety standards. Other important maintenance work includes a 2012 reroofing project ($11,000) and a foundation underpinning improvement in 2005 ($10,000).

The building's history includes several routine housing inspections (1996, 2001, 2004, and 2010) which identified various safety requirements that were subsequently addressed. These included issues with egress obstruction, fire extinguisher maintenance, door repairs, and security requirements, all of which were resolved within reasonable timeframes. More recently, there have been three fire extinguisher-related complaints in 2024 and 2008, which show ongoing attention to safety equipment maintenance, though the 2024 complaint appears still open as of the latest data. The property has experienced numerous parking-related issues, with multiple reports of driveway blocking between 2023 and 2024, though most resulted in officers being unable to locate the offending vehicles, with only two citations issued. The building's soft-story retrofit was classified as Tier 3 with work completed and a Certificate of Final Completion (CFC) issued, indicating full compliance with the city's seismic safety requirements.

Risk rating

How 561 Arguello Blvd'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 1723 buildings in this neighborhood, 896 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.

NOV rate, owner's portfolio

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

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 79.1%
Moderate concern 11.1%
Severe concern 9.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
