Building Improvement Grant Program

Main Street Portsmouth and the City of Portsmouth have partnered to offer a grant program for the purpose of promoting exterior building improvements to existing commercial properties in Portsmouth’s Downtown Improvement District. Every year a minimum of $25,000 is awarded to property owners within the Downtown Improvement District. The goal of the program is to improve the structural integrity, longevity and overall physical appearance of commercial buildings in Portsmouth’s Downtown Improvement District, therefore increasing the value to the owner and the community. Main Street Portsmouth and the City of Portsmouth believe property owners are a vital component to the success of the redevelopment and economic revitalization efforts in Portsmouth.
