Initial analysis

The three-unit multi-family residential building at 1172-1176 Clayton Street in the Buena Vista Park neighborhood, owned by Charles C & Carol Knappick, was constructed in 1940 as a three-story flats and duplex structure. The property has undergone several significant maintenance and improvement projects over the years, including a complete electrical system upgrade in 2006 featuring new service entrances, circuits, and panels, as well as a stucco facade investigation for dry rot in 2007. Historical records show a reroofing project was completed in 1989, and a routine apartment inspection was conducted in 2006.

The building faced multiple violations in September 2001 that were promptly addressed and resolved by October 2001, including security improvements (reinforcing entry doors and installing deadlatch locks), ventilation requirements for public halls, ceiling repairs, and gas leak remediation. Recent maintenance issues have primarily involved external factors, with multiple reports of graffiti (nine incidents between 2019-2023, all resolved), and a 2023 report of a public stairway defect on the property that was inspected and resolved by the Department of Public Works. While there have been periodic maintenance and safety issues in the building's history, most significant violations occurred in 2001 and have since been addressed, with no similar patterns reported in recent years. The property's identified issues have mostly revolved around exterior maintenance and public safety concerns rather than systemic building problems, and all known compliance issues have been resolved through proper channels.

Risk rating

How 1172-1176 Clayton 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 351 buildings in this neighborhood, 176 are predicted to be safer.

Model explanation

What's driving this score

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Neighborhood location

12-Month severity forecast

Moderate concern 21.5%
Severe concern 12.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
