Initial analysis

1827 Clement Street is a 2-story, 4-unit multi-family residential apartment building located in San Francisco's Central Richmond neighborhood, built in 1959 and currently owned by Daniel Haitao Hu and Hanying. The building's maintenance history includes a complete reroofing project completed in 1991, and two significant routine housing inspections in 2000 and 2009. The 2000 inspection, conducted by Housing Inspection Services, revealed multiple safety concerns that were subsequently addressed by February 2002, including the need for fire sprinkler installation at the garbage chute, smoke detector installation in the lobby, smoke enclosure door closer installation, and fire extinguisher recharging requirements. The 2009 inspection identified additional safety and maintenance issues that were resolved by December 2009, including the need for floor repair in the hallway outside Apartment 1, fire extinguisher updates, and improvements to exit door security features.

More recently, there has been a notable pattern of parking-related issues near the property, with multiple reports of driveway blocking incidents between 2022-2025. Of particular significance is a series of blocked driveway complaints from 2023-2024, though many of these were marked as "Unable to Locate" or "Invalid" by responding officers. There was one confirmed citation issued in July 2023. Other 311 calls regarding the property primarily relate to parking enforcement, with one general cleaning request regarding loose garbage reported and resolved in January 2024. While the building has experienced multiple routine inspections and required improvements in past decades, there are currently no active building violations or complaints on record.

Risk rating

How 1827 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.

Neighborhood percentile

Out of 2250 buildings in this neighborhood, 1575 are predicted to be safer.
