1597 22nd Ave, San Francisco, CA 94122

The two-unit residential building at 1597 22nd Avenue in the Central Sunset neighborhood is a two-story flats and duplex structure built in 1938, currently owned by Peter A. and Patricia D. Maschi.

The building's maintenance record shows relatively minimal major work, with significant permits including a reroofing project completed in 1992 and a gas houseline extension project completed in early 2018. A notable plumbing issue occurred in May 2004 when a tenant reported brown tap water, leading to an investigation by the Plumbing Inspection Division, though this complaint was resolved within two weeks. Recent history from 2024 reveals a series of urban environment-related incidents near the property, though none appear directly related to the building's structure or systems.

These include multiple reports of abandoned vehicles (all of which were gone upon inspection), street lighting issues, garbage and debris concerns, and Muni-related service complaints. Two fire department responses were recorded, but both were non-emergency situations: one was a false alarm and the other was a lock-in incident, neither resulting in civilian injuries. The most recent building-related incident was a construction plate issue reported in December 2024, which was promptly addressed and resolved by city services. The property has maintained compliance with basic maintenance requirements, though the relatively few permits on record since 1992 suggest limited major renovations or system upgrades.
