The cost to build a shed in Washington ranges from $1,860 to $12,370, with most homeowners paying around $5,570. Your actual cost depends on several factors specific to your home and the Washington-Arlington market.
Shed cost scales with size — an 8x10 (80 sq ft) shed costs roughly half of a 10x16 (160 sq ft) shed for the same material quality.
Wood sheds offer the best aesthetics and customization ($20–$60/sq ft). Metal sheds are cheapest ($10–$25/sq ft). Vinyl sheds are low-maintenance ($25–$50/sq ft).
A gravel pad is cheapest ($200–$500). Concrete slabs ($500–$2,000) are most durable. Pier blocks work for smaller sheds on level ground.
Adding lights and outlets to a shed requires a dedicated circuit run from the house, adding $500–$1,500 depending on distance.
Prefab shed kits save 30–50% over custom-built sheds and assemble in a day. Custom sheds offer exact sizing and design flexibility.
The Northeast tends to have higher labor costs, partly driven by stronger union presence and higher cost of living. Stricter building codes mean more inspection requirements — budget extra for permits.
Budget $70–$420 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Year-round construction seasons give you the most flexibility for exterior projects. Take advantage by scheduling during slower months for potentially better rates.
Handy homeowners with basic tools can handle straightforward shed construction. If your project involves the panel, new circuits, or gas lines, hire a licensed pro. DIY can save $1,757–$2,259 in labor.
