Lowell lot coverage limits range from about 30 percent in suburban single-family zones to 80 percent or more downtown, with open space requirements in multifamily districts.
Lot coverage in Lowell is the percentage of a parcel covered by buildings and, in some districts, by all impervious surfaces. Suburban Single Family districts typically cap building coverage around 30 percent. Traditional Single Family and Two Family districts allow 40 to 50 percent. Urban Multifamily and downtown districts allow 70 to 80 percent or more to match the dense mill-city context. Multifamily projects usually have minimum open space and landscaping requirements in addition to coverage caps. Impervious surface triggers in the Lowell Stormwater Ordinance may require on-site infiltration for new projects over a threshold. Confirm exact figures in the schedule of dimensional regulations in the ecode360 zoning text.
