Initial analysis

The property at 478-480 2nd Avenue in the Inner Richmond is a two-story, multi-family residential building constructed in 1907, containing three units and currently owned by Nyna Van Atta. The building has undergone several significant renovations and repairs over its history, with major work completed in 1999 including a vertical addition and plumbing fixture replacements. The late 1990s also saw interior improvements including shower and countertop replacements, while in 1997 two front windows were replaced. More recent maintenance includes repairs to the rear deck railing in 2009 and structural work on the south side stairs in 2005, which followed a series of building violations from late 2004 to early 2005. These earlier violations, which were all abated by March 2005, included issues with wood structural posts, stair repairs, fire safety concerns (including smoke detectors and fire extinguishers), emergency exits, and the requirement for gas utility shutoff tools.

The building's permit history shows a mix of completed and expired permits, with the most recent work being the rear deck repairs in 2009, though the building underwent more substantial improvements in the late 1990s. A rear yard variance was approved to raise the roofline on this non-complying structure, indicating regulatory compliance efforts. The property has been subject to regular routine inspections by Housing Inspection Services, with the most recent documented inspection occurring in 2011. While the building has experienced various maintenance issues over its history, particularly during the early 2000s, the prompt resolution of violations and completion of necessary repairs suggests ongoing attention to building upkeep and safety compliance, though prospective tenants should note the building's age and history of structural and safety-related violations from nearly two decades ago.

Risk rating

How 478-480 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.

Estimated permit spend (past 7 years)

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Building permits, owner's portfolio

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

12-Month severity forecast
No violation 72.3%
Moderate concern 19.0%
Severe concern 8.7%
