The three-unit, three-story multi-family residential building at 160-164 4th Avenue, owned by Julie C. Nishihara, has a documented history dating back to its 1904 construction. The building, classified as Flats & Duplex, has undergone several significant improvements over the years, with the most recent major infrastructure upgrade being a new 200-amp electrical service installation permitted in September 2024.

Previous significant maintenance work includes a complete reroofing project in 2006 costing $15,000, window replacements in the third-story unit in 1998, reconstruction of the back staircase in 1997, and a building code compliance update in 1986. The property has maintained regular safety oversight through routine housing inspections by Housing Inspection Services, with the most recent inspection occurring in January 2016. Earlier inspections took place in 2004, 2010, and 1999, all of which were completed without noted issues.

A street space scaffold permit was issued in 2010, though the specific purpose was not detailed in the records. The building's maintenance record suggests ongoing attention to structural and safety requirements, with no active complaints or violations currently on file. The documented improvements and regular inspections indicate a pattern of proactive maintenance and compliance with regulatory requirements.
