Initial analysis

The three-story multi-family residential building at 419-421 2nd Avenue in the Inner Richmond, owned by Yuk Ling Ng Revoc Tr, is a 2-unit flats and duplex structure built in 1907. The property experienced a significant adverse event in October 2015 when a fire caused substantial damage to the top unit (421), hallway, light well, and portions of vinyl siding, leading to emergency responses and subsequent building violations. The building underwent extensive rehabilitation in 2016, completed at a cost of $150,000, which included replacing damaged wood framing, updating plumbing and electrical systems, remodeling kitchens and bathrooms, and replacing windows throughout both units. This renovation also featured the installation of new gas furnaces, service panels, and comprehensive plumbing updates for multiple bathrooms and kitchens.

In terms of recent maintenance and resident experience, the building has had several plumbing and electrical upgrades since the 2016 renovations, including furnace and service panel installations. The property has had multiple street-related complaints in recent years, with the most recent being garbage and debris issues in 2024, though these appear to be external to the building itself. Historical records show earlier improvements including the installation of vinyl siding in 1996 and aluminum windows in 1989. The building's planning records indicate that the 2016 renovation complied with requirements for usable open space and proper bathroom configurations, and documented that more than 75% of the interior framing was replaced during the renovation period. The property has maintained an active but resolving history of 311 calls regarding street cleaning and parking issues, though these are generally related to exterior conditions rather than building-specific concerns.

Risk rating

How 419-421 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.

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.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 82.7%
Moderate concern 12.8%
Severe concern 4.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
