Initial analysis

The two-unit residential building at 831-833 Arguello Blvd in San Francisco's Inner Richmond neighborhood is a two-story flats and duplex structure built in 1908, currently owned by Ronald C & Marian Won since 1985. The property has undergone several significant maintenance and improvement projects over the past two decades, including a complete reroofing of the flat roof in 2016 (cost: $7,500), installation of seven vinyl windows in 2001 (cost: $2,751), and most recently, an electrical upgrade in 2022 that included installing wire mold raceway in four rooms and upgrading the electrical service to two meters with 100-amp disconnects (cost: undisclosed). A notable building complaint was filed in August 2013 regarding construction work on the rear of the building, which led to repairs of an existing stairway using redwood handrails and pressure-treated wood for stringers, posts, and beams in compliance with the complaint's requirements (cost: $3,000). The building's recent maintenance history appears to be generally proactive, with the most significant structural and safety work (electrical upgrade) completed within the past year.

The property has experienced various maintenance and environmental challenges typical of urban residential settings, including multiple incidents of graffiti (most recently in December 2023), illegal parking issues (including a resolved citation in July 2021), and tree maintenance needs (an overgrown tree blocking the sidewalk reported in November 2018). A pattern of abandoned motorcycle vehicles in the vicinity was noted between 2017-2018, though all were resolved when vehicles were no longer present. The building's property management has generally addressed infrastructure and maintenance issues as they arise, with the majority of building permits being properly obtained and completed, though the 2013 complaint suggests there was some work completed beyond the original permit scope at that time. The most recent structural improvements focus on safety and modernization, particularly with the recent electrical system upgrade, which brings the building's infrastructure more in line with contemporary standards.

Risk rating

How 831-833 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.
