Initial analysis

The 6-unit, 2-story multi-family residential building at 463 6th Avenue in the Inner Richmond, owned by Eileen Carol Marchasin, was constructed in 1964 and has undergone several significant modifications and faced various maintenance challenges over the past decades. Most notably, the building completed a mandatory soft-story retrofit in 2017 (cost: $92,000) to meet seismic safety requirements, and earlier improvements included window replacements in 2013 (cost: $2,000) and roof work in 2005 (cost: $5,500). The building has experienced recurring water-related issues, particularly in recent years, with multiple complaints filed between 2020-2024 regarding leaks, mold, and water damage affecting windows, skylights, and other areas, including recent complaints in 2023 and 2024 about water intrusion and mold. The property has also faced various maintenance challenges, including security violations, deteriorated floor drain covers, and multiple infrastructure issues as documented in 2015-2016 violations. Three historical fire safety complaints (2016-2017) were recorded regarding blocked exits, though two were resolved with corrections and one was found to have no merit. The building has a recorded address history featuring routine service calls, primarily related to parking issues and street conditions, along with two documented fire department responses for elevator rescue and public service. The building's maintenance history shows a pattern of addressing structural and safety concerns, though water-related issues appear to be persistent and ongoing as of 2024.

Risk rating

How 463 6Th 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.
