Initial analysis

The three-story multi-family residential building at 505-511 Laguna Street in Hayes Valley, owned by the James J Stacy 2011 Revocable Trust, was constructed in 1885 and contains four units plus commercial space. The property has undergone several significant renovations and improvements over the years, with the most recent major work being a kitchen remodeling project completed in 2013 that included new cabinets, countertops, appliances, and electrical upgrades. In 2007, the commercial space underwent a substantial transformation from a retail art gallery to a restaurant, involving extensive electrical work, plumbing installations, and various accessibility improvements. The building experienced multiple violations in 2007 related to fire safety, security, and general maintenance issues, all of which were abated by May 2012, and underwent routine safety inspections in 2011 and 2018. Recent activity includes tree maintenance, garbage cleanup, and environmental noise complaints recorded in early 2025.

The property has also been the subject of various 311 calls in recent months, primarily concerning garbage and debris on the street, with several cases being resolved promptly. Planning records indicate the installation of telecommunications equipment (AT&T antennas) on the rooftop, though this required special permits to legalize. Recent fire complaints in 2021 related to shared spaces and operating without a permit were both resolved with conditions corrected. The building's maintenance history shows attention to both residential and commercial components, with regular inspections and prompt response to violations, though the recent increase in 311 calls regarding street cleaning issues may warrant observation. The property underwent roof replacement in 2003 as part of its infrastructure maintenance.

Risk rating

How 505-511 Laguna St's risk score is calculated
