Initial analysis

The Wong Family Trust's property at 141-143 Clement Street is a two-story mixed-use building constructed in 1900, containing two residential units and commercial space, located in San Francisco's Inner Richmond neighborhood. The building underwent significant renovations in 2010 when the ground floor was converted from a vacant spa to a preschool, involving extensive work valued at $60,000 including the installation of new restrooms, sinks, and critical fire safety upgrades such as a new fire panel and protection devices throughout the premises. More recently, in March 2024, the building completed two permit actions to legalize previously unauthorized improvements, including an awning and associated signage for "Building Kids School," which were addressed through the Awning Amnesty Program following complaints filed in 2022 about unpermitted work and potential window obstruction.

The property has maintained regular upkeep, as evidenced by multiple sidewalk repair permits between 2003-2006 and various fire safety improvements. While there have been several maintenance and compliance issues noted through 311 calls and building complaints, most have been resolved through appropriate channels. Recent concerns include graffiti (2022-2024), a sidewalk blockage due to merchandise display (2021), and waste disposal issues (2023), though these are primarily maintenance matters rather than structural or safety concerns. The building's historical records suggest proper attention to fire safety requirements, with multiple permits showing compliance with modern safety standards.

Risk rating

How 141-143 Clement 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.
