Initial analysis

The two-unit residential property at 770-772 Clementina Street in San Francisco's South of Market neighborhood is a two-story flats and duplex building constructed in 1910, currently owned by Christopher J. Groening. The building's maintenance record shows several significant improvements over the years, including a completed re-roofing in 2011 costing $9,600, and the most recent development being the issuance of a plumbing permit in October 2024 for the replacement of a 40-gallon gas water heater in the basement. Historical records from the 1990s indicate fireplace-related improvements, including the installation of a zero-clearance fireplace and associated modifications to the front exterior moldings and stucco, though some of these permits expired without completion.

The property and its immediate vicinity have experienced various urban challenges over the past few years, particularly related to street cleanliness and public safety. The most recent service requests between December 2023 and September 2024 primarily involved street cleaning matters, including reports of loose garbage, debris, and waste removal needs. There were also several significant public safety and health-related incidents recorded in 2024, including three encampment-related calls, with one in July requiring syringe disposal, and a request for homeless outreach services in June. The building itself appears to have received regular basic maintenance, as evidenced by the completed water heater replacement permit, though the frequent street cleaning complaints suggest ongoing neighborhood challenges with waste management.

Risk rating

How 770-772 Clementina 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.
