Augrented Insights Report

The four-unit, three-story multi-family residential building at 4249-4251 20th Street in the Eureka Valley/Dolores Heights neighborhood, owned by Cedric C. Yap, has undergone significant renovations and faced some challenges since its construction in 1906. The property underwent major improvements in late 2016 and early 2017, including comprehensive plumbing and electrical upgrades across multiple units, window replacements, and HVAC system overhauls.

Notably, units 305 and 307 received substantial remodeling work including new shower pans, kitchen and bathroom renovations, and complete rewiring. The building experienced a fire incident in late 2016 that necessitated electrical system repairs, but all related work was completed by early 2017. The property has maintained an active maintenance and improvement schedule, with multiple street space permits issued between 2016-2017, and recent utility work being carried out in 2024.

Historical records show a cluster of violations from 2006 related to interior surfaces, water damage, and lead paint concerns, all of which were abated by 2009. Recent maintenance issues have included two instances of sewage backup in 2017, both of which were resolved. The building's recent permit activity and work completion status indicate regular maintenance and upgrades have been prioritized, though there remains an open case from December 2024 regarding graffiti on a pole near the property.
