Initial analysis

The property at 1336-1338 Lake Street is a two-unit, two-story multi-family residential building constructed in 1941 and currently owned by Mike Chiang. The building has undergone several significant improvements over the past decade, including a substantial renovation in 2016-2017 that added a gym room, sun room, and new bathroom facilities on the ground floor ($50,000 project cost). Important maintenance work has been performed, including termite remediation in 2013 addressing dry rot issues at the rear stairs and right front sheeting ($3,000), a complete reroofing project in 2011 ($17,850), and a sewer line replacement in 2011. The building's electrical system was upgraded in 2003 with the installation of a 100-amp sub-panel and service ground rod.

The property has experienced some infrastructure challenges, most notably with its sewer system, as evidenced by two sewage backup incidents in 2016 and 2021 (both involving 4-inch vents). There have also been two documented tree-related issues in 2020, where trees were reported as damaging the property and hitting windows. The building's location has faced intermittent parking challenges, with multiple incidents of blocked driveways resulting in citations between 2020 and 2022, though these are external matters not directly related to the building's condition. The property maintains good compliance with city requirements, with no recorded planning code complaints or violations, and all recent improvements have been carefully documented through proper permitting channels.

Risk rating

How 1336-1338 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.

Neighborhood percentile
82th percentile

Out of 660 buildings in this neighborhood, 119 are predicted to be safer.
