AI summary

The three-unit, two-story multi-family residential building at 788 Arguello Boulevard, owned by Chung-chih Yu (also known as Sammy Yu), has undergone several notable improvements and faced some community challenges since 2016. The property, which dates back to 1900, has seen significant electrical upgrades, including a main service upgrade to 100 amps with a sub-panel installation and new outlets completed in 2016, and the installation of track lighting in 2021. Accessibility improvements were made in 2021 with the replacement of an entry door to comply with ADA requirements. The building has required various maintenance work, including floor repairs in 2020 and a countertop replacement in 2016.

The property has experienced some ongoing challenges with sidewalk access and public space use, particularly regarding café tables and chairs, with multiple service requests in 2024 showing a pattern of blocked sidewalks. There have also been recent issues with illegal postings, graffiti (on a bike rack and news rack), and parking enforcement matters in 2024. While many of these cases have been resolved, including some related to valid permits, they indicate ongoing interactions with city services. The building's historical records show some older maintenance work such as reroofing in 1999, though that permit has expired. Notably, there was a tenant buyout in 2016 involving four tenants for $35,000, which warrants consideration of the building's past rental dynamics.

Risk rating

How 788 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

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.

Estimated permit spend (past 7 years)

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 80.1%
Moderate concern 14.3%
Severe concern 5.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
