Initial analysis

The property at 425 4th Avenue is a 2-unit, 2-story multi-family residential building constructed in 1906, currently owned by Kenny & Henrietta Kan. The building's maintenance history shows significant attention to both routine upkeep and corrective actions, particularly following a series of violations in 2016 that classified the property as a nuisance under Section 1001-d of the San Francisco Housing Code. These violations, all resolved by August 2019, included issues with water damage, mold/mildew, smoke detector compliance, interior surface conditions, and stair maintenance. More recent improvements include substantial renovations in 2023, comprising bathroom and kitchen remodels in Unit #427 (completed in January 2023), the installation of new baseboard heaters in bedrooms/living rooms (June 2023), and electrical updates related to the remodeling work.

The building has experienced some notable infrastructure challenges, including a 2023 complaint regarding roof issues and heating concerns, both of which were eventually resolved by November 2023. Historical maintenance work has included various stair repairs (1997, 2016), a bathroom/basement addition (1997), and reroofing (1995). A gas leak incident was recorded but without any civilian injuries. The property has been subject to multiple 311 calls in recent months (late 2024), primarily related to street cleaning, garbage debris, and parking issues, though these are external to the building itself and were generally resolved by city services. While the building has had its share of maintenance challenges, recent improvements and the resolution of past code violations suggest ongoing investment in the property's upkeep and compliance with housing standards.

Risk rating

How 425 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.
