Doing business in Suffolk County
Suffolk County is small in area but dense in business. It is made up of Boston, Chelsea, Revere and Winthrop, and it counted 33,364 establishments and 713,809 jobs in 2024. Its average annual pay of $131,280 is the highest of any Massachusetts county, and with about 21 jobs per establishment it has the largest employers on average. Financial firms, hospitals, universities and law practices anchor the county, while restaurants, salons and delivery businesses make up much of the new LLC demand we see.
All land documents for the county record at one office, the Suffolk County Registry of Deeds on New Chardon Street in Boston. Investors buying triple-deckers in Dorchester or condos in Chelsea through an LLC will record the deed there, and lenders usually ask for a recent Corporations Division certificate of good standing before closing.
Boston has its own business certificate rules: $65 at the City Clerk, plus $35 for non-resident owners, renewed every four years. Chelsea, Revere and Winthrop each keep their own clerk's records, so a business certificate follows the office location, not the county.
