1410-1412 29th Ave, San Francisco, CA 94122

The two-unit residential building at 1410-1412 29th Avenue in the Central Sunset neighborhood, owned by the Chan Family Trust, was constructed in 1945 as a two-story flats/duplex structure. The property has undergone several significant modifications and faced multiple compliance challenges over the years.

Most notably, in 2006, a building violation was filed regarding unauthorized modifications to a previously permitted family room and half bathroom in the rear garage area, which had been illegally converted into additional living space with unapproved wiring and plumbing. This situation was resolved by April 2007, when the owners obtained proper permits to remove an unauthorized kitchen installation and add a bathtub in the existing bathroom, completing the work at a cost of $5,000. The building's modification history includes several permitted improvements, such as a horizontal addition in 1992, corrections to dimensions in 1993, reroofing work in 1991, and repair of damage to side stairs in 1988.

There have been three separate complaints regarding possible illegal unit conversions between 2006 and 2010, all of which were subsequently resolved, though these incidents suggest historical challenges with unauthorized modifications. The most recent recorded issue related to the property's infrastructure was a pavement defect reported in December 2019, which was promptly resolved by city services. The property's documented permit history shows regular maintenance and improvements over time, with the most significant structural changes occurring in the early 1990s, while more recent activity has primarily focused on compliance-related fixes.
