The Downtown Boston Alliance (DBA), formerly known as the Downtown Boston Business Improvement District, was created by property owners committed to achieving the district’s full potential as a premier and vibrant destination. Our mission is to significantly improve the experience of all who live, work, visit, go to school, or shop in the 34-block, 100-acre DBA service area by providing supplemental services to keep the district clean, safe, and vibrant while catalyzing an energetic and thriving business climate and serving as the neighborhood’s voice and advocate.
