Prices include delivery and standard installation on a gravel or deck-block foundation. Custom foundations, interior upgrades, and site prep may add to these ranges.
Small Sheds: 8x10 and 8x12
Small sheds work well for lawn equipment, garden tools, and light storage. At 80–96 square feet, they fall under the 120-square-foot permit threshold in most Massachusetts towns — meaning no building permit required in many cases (more on that below). Expect to pay $3,500–$7,500 for a quality small shed in this size range.
Mid-Size Sheds: 10x14 and 12x16
This is where most homeowners land. A 10x14 or 12x16 gives you real workshop or storage space without taking over the backyard. These sizes typically require a building permit in Massachusetts. Budget $6,000–$12,500 for a mid-size shed, depending on material and options.
Large Sheds: 12x20 and 14x20
Large sheds bridge the gap between storage and workspace. Many homeowners use them as hobby shops, potting sheds, or secondary garages for lawn tractors and ATVs. Prices in Massachusetts for this range run $9,000–$18,000 installed, with vinyl at the higher end.
Extra-Large Sheds: 16x24 and Beyond
At 384+ square feet, extra-large sheds are serious structures. Permitting, engineering requirements, and site prep become more involved. Prices generally start at $14,000 and climb well past $20,000 depending on finishes and foundation. If you're in this territory, a site visit and custom quote is the right next step.
