Initial analysis

The property at 4320-4322 18th Street is a historic 2-story, 2-unit multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood, constructed in 1897 and currently owned by William J. Kenna Jr. The building has undergone substantial recent improvements, including a comprehensive window replacement project completed in May 2024 valued at $92,616, and significant interior remodeling work in 2022 that renovated kitchens and bathrooms on the 2nd and 3rd floors, relocated laundry facilities, and converted existing laundry rooms to bedrooms (cost: $130,000). Additionally, solar photovoltaic panels were installed in July 2024, demonstrating an investment in sustainable energy infrastructure. The property has maintained attention to basic infrastructure, with electrical service upgrades to 160 amp and various safety improvements completed over the years, including roof replacement in 2004 and various interior renovations.

Historical records show the building faced multiple maintenance challenges in the early 2000s, with several violations issued in May 2001 regarding weather proofing, handrails, lead paint hazards, and broken windows, though these violations were all abated by October 2005. The property experienced periods of deterioration in 2003, with complaints about siding, windows, paint, and debris, but recent renovations suggest these issues have been adequately addressed. The building's systems have been progressively upgraded, including electrical improvements in 2004 and 2022, and significant plumbing work completed in late 2022. Recent 311 calls from 2024 primarily relate to street cleaning and encampment issues in the vicinity, though these are external to the property itself. The most recent planning records confirm the approval of window replacements and attic conversion projects, though the latter was subsequently reduced in scope with no changes to the attic level.

Risk rating

How 4320-4322 18Th 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.
