Initial analysis

The two-unit residential building at 1414 34th Avenue in San Francisco's Central Sunset neighborhood is a two-story flats and duplex structure built in 1945, currently owned by Lee Kan Wan & Jennie K T 19. The building's documented history shows relatively few significant issues, with one notable infrastructure change from 1984 when a wash room was added to the basement. The most recent documented incident was a driveway blocking violation in June 2024, which resulted in a citation being issued. The property has experienced recurring parking-related challenges in recent years, with multiple 311 calls between 2020-2024 regarding vehicles blocking driveways or parking on sidewalks, though many of these incidents could not be validated upon officer response, except for a citation issued in June 2021.

Sewer infrastructure was addressed in September 2020, when there was a sewage backup incident involving a 4-inch vent that was subsequently resolved by PUC Sewer Operations. The building's rent board fee and housing inventory status was clarified in November 2023, confirming the property is exempt from the rent board fee, as communicated to the caller. While the property has experienced a moderate number of parking-related complaints over the past few years, these primarily involve street-level issues rather than building-specific problems, and the only significant infrastructure modification on record remains the 1984 basement washroom addition.

Risk rating

How 1414 34Th 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 814 buildings in this neighborhood, 204 are predicted to be safer.
