Initial analysis

The property at 490-496 2nd Avenue in San Francisco's Inner Richmond district is a 2-story, 4-unit multi-family residential building constructed in 1922, currently owned by Shum & Sons LLC. The building has undergone several significant improvements over the past two decades, including the installation of 22 new wood windows in 2007 ($21,500), a complete roof replacement in 2004 ($6,000), and the repair of dry rot issues in the basement in 1987.

The property underwent periodic safety inspections between 1999 and 2017, with the most recent routine inspection in 2016 revealing multiple fire safety concerns that were subsequently addressed by May 2016, including the need for fire extinguisher servicing, stair repairs, and carbon monoxide alarm installations. A 2017 complaint noted potential lead paint concerns due to the building's age, though this was marked as "Not Active" on the same day it was filed. Since October 2023, there have been several maintenance-related service requests, primarily regarding street cleaning, garbage, and parking issues near the property, with most being resolved promptly. A single EMS incident was recorded at the address, with no civilian injuries reported. The building's permit history shows regular maintenance and updates, particularly focusing on windows, roofing, and addressing structural issues as they arise, with no recent major renovations or violations on record.

Risk rating

How 490-496 2Nd Ave'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, 1172 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.

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.

12-Month severity forecast
No violation 66.6%
Moderate concern 22.1%
Severe concern 11.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
