The three-story multi-family residential building at 531-533 21st Avenue in the Central Richmond neighborhood, owned by Penny A Baker 2015 Revocable Trust, has undergone several significant improvements since its construction in 1926. The most recent major work was completed in 2022 with the installation of Milgard white vinyl windows at the rear of the building, totaling approximately $19,000.

Prior improvements include comprehensive bathroom renovations in 2014, with the addition of a new full bathroom in the upstairs penthouse bedroom, and the replacement of multiple windows with Fibrex windows and new trim, along with wood siding replacement on the top floor. The building has also seen important infrastructure updates, including a main sewer line replacement in 2019, a house trap replacement in 2015, and foundation underpinning work in 2004 due to adjacent excavation. Recent maintenance concerns have emerged, with multiple 311 calls regarding sidewalk parking violations occurring between August 2024 and October 2024, indicating an ongoing issue with parking compliance in the area.

A sewage backup incident was reported and resolved in November 2023. The building's maintenance history shows regular upkeep, including electrical and plumbing updates during the 2014 renovations, though there was one documented complaint in 2007 regarding unpermitted construction work that was quickly addressed. The property has maintained a pattern of proactive upgrades, with improvements to windows, bathrooms, and infrastructure being the most notable recent developments.
