Initial analysis

The 4-unit, 2-story multi-family residential building at 459 11th Avenue in the Inner Richmond, built in 1915 and currently owned by the Ung & Mabel Lee Living Trust, has undergone several significant safety and maintenance updates over the years. Most notably, the building completed a mandatory soft-story retrofit in 2017 at a cost of $86,750, bringing it into compliance with 2012 and 2015 seismic safety requirements, with the work now classified as Tier 3 with a Certificate of Final Completion issued. The building has a documented history of addressing structural and safety concerns, including termite repairs completed in 1988 and multiple building violations in 2002 that were resolved by June 26, 2002. These violations included security and fire safety issues such as the need to replace hollow core doors, install self-closing devices at exterior doors, address combustible storage concerns, and relocate garbage receptacles - all of which were subsequently addressed.

In more recent history, a paint-related concern emerged in 2012 regarding peeling exterior paint on the south side of the building, with initial fears about potential lead paint hazards, though this issue was abated within approximately one month. The building's recent history (2019-2023) includes several routine inspections and three 311 calls related to street and sidewalk issues (not directly related to the building's condition), including reports of human or animal waste (2022), an abandoned vehicle (2021), and graffiti (2020), all of which were resolved or closed by the respective authorities. The property appears to be maintaining compliance with current safety standards, particularly following the completion of the soft-story retrofit program and the resolution of historical violations.

Risk rating

How 459 11Th 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, 1327 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 57.0%
Moderate concern 31.2%
Severe concern 11.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
