1840 Church St, San Francisco, CA 94131

The two-unit residential property at 1840 Church Street in Glen Park, owned by Carlos E Calderon, has been facing significant maintenance and compliance challenges in recent years. Built in 1979, this two-story flats/duplex building has experienced persistent water-related issues, with multiple complaints between 2017-2018 reporting water intrusion, mold, and dilapidated conditions affecting multiple units. Notably, there is an active violation from April 2024 regarding an alleged illegal third unit behind the garage, with associated concerns about unapproved construction work, wiring, plumbing, and fire safety deficiencies.

Most concerning are the recent complaints from February 2024 about unpermitted roof work, deck rebuilding, and structural problems. Historical records from 1999 indicate prior issues with unauthorized uses of the garage space, including concerns about a mechanic shop and illegal car repair business operations. Recent activity at the property shows ongoing maintenance and compliance issues, with multiple complaints and violations remaining unresolved as of 2024.

In addition to the building and habitability concerns, there have been several complaints regarding illegal parking in the vicinity throughout early 2025, though these could not be consistently validated by responding officers. The property has also generated service requests related to exposed wires, garbage issues, and utility billing matters, though many of these were resolved through normal channels. Given the pattern of persistent maintenance issues, particularly regarding water damage and unauthorized modifications, these records suggest ongoing challenges with building upkeep and regulatory compliance.
