Initial analysis

The two-story multi-family residential building at 1631-1637 Folsom Street, located in San Francisco's South of Market neighborhood, is a 4-unit apartment complex constructed in 1912 and currently owned by Hector M Correa Car. The building's maintenance record shows minimal major work, with the only significant permitted work being a complete reroofing project undertaken in 1988. A routine safety inspection conducted by Housing Inspection Services in May 2008 noted comments regarding fire extinguishers inside the units, though this violation was promptly addressed and marked as not active on the same day.

The property has experienced numerous street-related issues in recent years, particularly concerning parking violations and street maintenance. Between 2020 and 2024, there were multiple reports of vehicles blocking bicycle lanes, driveways, and street cleaning issues, including garbage and debris problems. Notably, there were two documented instances of driveway blocking in 2022 that resulted in one vehicle being towed. Most recently, in April 2022, there was a report of a damaged tree with a hanging limb that remains in progress. The building's violation and complaint history suggests generally prompt resolution of issues directly related to the building itself, with most concerns arising from external street conditions rather than the building's internal systems or maintenance.

Risk rating

How 1631-1637 Folsom 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.
