Massachusetts: Most Expensive Counties

What "most expensive" really means for Massachusetts renters

These rankings come straight from HUD's FY 2026 Fair Market Rent schedule, which reports the 40th percentile of gross rents (utilities included, except telephone) for every county in Massachusetts. The top entry is Essex County with a 1-bedroom at $2,476, a studio at $2,359, 2-bedroom at $2,941, 3-bedroom at $3,526, and 4-bedroom at $3,894. Because HUD sets FMR per county (or per metro FMR area), these figures are the ceilings local housing authorities use to calibrate Section 8 Housing Choice Voucher payment standards — typically between 90% and 110% of FMR — which means they also approximate the moderate end of each county's documented rental market.

Compared with the Massachusetts state average of $1,796 for a 1-bedroom, the most expensive county is 38% above the state benchmark, and 158% above the US average of $959. High-rent counties almost always cluster in dense metropolitan FMR areas where housing supply is constrained, transit access is strong, and local wages support premium rents — which is also why voucher recipients frequently find fewer units at payment-standard rates in these counties without the help of HUD's Small Area FMR program. The ranking across all 14 counties shows the intra-state spread: moving between a top-ranked county and a mid-ranked one can mean hundreds of dollars per month in baseline rent before any amenity premium.

For budgeting, the 30% affordability rule says a household needs roughly $99,040/year to afford the most expensive 1-bedroom FMR in Massachusetts without being cost-burdened — well above the $71,840/year needed to afford the state average. That gap translates directly into rent-burden rates: counties at the top of this list tend to have the highest share of households paying more than 30% of income for rent, and the highest share of severely burdened renters (above 50% of income). Pair this ranking with the year-over-year FMR growth and rent burden pages to see whether today's most expensive counties are still tightening, or whether lower-ranked counties are catching up fastest.
