Initial analysis

The two-unit duplex at 334 10th Avenue in the Inner Richmond, owned by William J & Marie A H Madde, is a two-story multi-family residential building constructed in 1904. The property experienced significant maintenance issues in late 2022, when multiple violations were documented under complaint number 202200050, including water damage, mold concerns, and electrical outlet problems. These violations were addressed and officially abated on July 6, 2023, following the replacement of four leaking windows on the south wall (not street-facing) in April 2023, at a cost of $4,000. The building has a history of roofing work from 1993, though those permits have since expired, and a sidewalk-related permit from 2007.

In recent months, there have been numerous reports regarding garbage and debris management in the vicinity of the property, with Recology responding to ten separate incidents between May and December 2024, primarily related to abandoned garbage and overflowing city garbage cans. These exterior maintenance issues have been consistently resolved, though one bike rack damage report from September 2024 remains open as of October 2023. The building's major interior maintenance issues from late 2022 have been resolved, though the property has required multiple interventions for exterior cleanliness in recent months, suggesting active management of both historical and current maintenance issues.

Risk rating

How 334 10Th 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.
