The 4-unit, 2-story multi-family residential building at 255 20th Avenue in the Central Richmond neighborhood, owned by Annie Liang 2019 Family Trust, has undergone several significant renovations since its construction in 1965. Most recently, in July 2024, the building completed a substantial electrical upgrade, replacing five electrical sub-panels and performing related minor wood framing work, along with plumbing improvements including the replacement of a water closet in unit #4. In 2018, the property received window upgrades, replacing four front windows with fiberglass units and other non-visible windows with vinyl replacements.

The building experienced notable maintenance challenges in 2008, including multiple complaints regarding lack of heat, hot water, and electrical issues, which required corrective actions including kitchen remodels, furnace replacements, and electrical work in unit #4, along with kitchen cabinet replacements in units #2 and #3. Earlier building violations from 2002 were resolved, involving fire safety equipment, smoke detector installation, and lighting improvements. Historical records show various routine maintenance and upgrade work, including a reroofing project from 2003 and deck modifications from 2000.

The building has had periodic inspections and maintenance work over the years, with particular attention to HVAC systems, electrical infrastructure, and window replacements. Recent 311 calls primarily relate to parking enforcement issues regarding blocked driveways, though these are external to the building's maintenance concerns. The property's maintenance record shows a proactive approach to addressing building violations and upgrading critical systems, with most recent works focusing on electrical infrastructure improvements to enhance resident safety and comfort. The building's age and history suggest ongoing maintenance is typical for this type of property, with major systems receiving periodic upgrades as evidenced by the recent electrical panel replacement project in 2024.
