Initial analysis

The 645-647 Lake Street property is a two-unit, two-story multi-family residential building constructed in 1909, currently owned by Jody Wilson and Yuriko Takata. The building has undergone several significant improvements over the past decade, including comprehensive window upgrades with two separate projects in 2017 and 2018 totaling approximately $31,200 in window replacements, a trenchless sewer line replacement in 2018, and a sewer trap replacement in 2009. There was one notable construction-related complaint filed in February 2021 regarding unexpected construction noise during work hours, which was eventually abated in January 2022.

The property has experienced some infrastructure and maintenance issues typical for its age, including a sewer backup incident in October 2020 that was resolved by PUC Sewer Operations. Recent permit activity shows attention to external improvements, with street space permits issued in 2013 and 2018. Multiple 311 calls regarding the property have been recorded, primarily related to external issues such as illegal postings, parking concerns, and sidewalk maintenance, though most of these cases were either resolved or closed due to administrative processes. The building's maintenance history shows regular attention to both interior and exterior requirements, with no recent complaints indicating ongoing structural or safety concerns.

Risk rating

How 645-647 Lake St'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.
