Initial analysis

The property at 484-486 4th Avenue in the Inner Richmond is a two-story, multi-family residential building constructed in 1908, containing two units. The building underwent significant modifications between 2007-2009 following a complaint about unauthorized modifications that took place in July 2007, when an illegal unit conversion in the garage area, including a habitable room and bathroom, was discovered. The building owner subsequently obtained permits to legalize these modifications, which included constructing new walls for a hallway, and underwent various inspections to address multiple safety concerns including heating, wiring, plumbing, and fire safety violations. All of these violations were officially abated by July 14, 2009.

More recently, the building has undergone several HVAC system upgrades, with the most recent work being the installation of a ductless mini-split heat pump system in January 2023. This followed previous furnace installations and updates to the building's electrical system in 2015-2016, including work on furnace installation in the attic and electrical upgrades to 110-amp service. The property has maintained routine compliance with basic building upkeep and safety requirements since the resolution of the 2007 violations, with no further building code violations recorded. While there have been various street cleaning and maintenance issues in the vicinity of the property reported through San Francisco's 311 system between 2019-2025, these were related to public street maintenance rather than building-specific concerns.

Risk rating

How 484-486 4Th 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, 414 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.

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.

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 82.6%
Moderate concern 12.9%
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.
