Connecticut Senate Bill 456 Forces Hartford Developers to Include Affordable Housing
The measure requires new housing projects in Hartford to include a set share of lower-cost units, shifting costs for some property owners while expanding options for local renters.
How we reported this
Connecticut Senate Bill 456 took effect after passage in the General Assembly on June 15. The law sets a 10 percent affordable unit requirement for most new multifamily developments of 20 units or more in cities including Hartford. Developers must price those units at no more than 60 percent of area median income.
The legislation responds to a 2025 state housing assessment that identified a shortfall of 18,000 units priced for households earning under $50,000 in the Hartford metro area. Municipalities now must update zoning codes by December 2026 to meet the mandate or risk losing certain state infrastructure grants.
Who gains and who faces added costs
Hartford renters in zip codes 06112 and 06120 stand to see more units listed below market rates once projects clear local review. A 120-unit complex proposed near the Connecticut River would now reserve 12 apartments for qualifying households. Property owners converting older buildings into apartments report higher legal and design fees to meet the new standards.
State budget documents show $12 million set aside in the current fiscal year for technical assistance to cities updating their ordinances. Hartford planning staff have already scheduled three public sessions in August to explain the changes to neighborhood groups.
Local advocates note that smaller lot owners in the South End may delay projects because the requirement applies only above the 20-unit threshold. Larger firms with access to state tax credits are positioned to absorb the added expenses more easily.
Implementation begins January 1, 2027. The Department of Housing will track annual reports from each municipality and publish the first compliance summary in March 2028.
