Foundation Options
Every shed needs a level foundation. The right choice depends on shed size, soil conditions, and local codes.
- Concrete blocks on gravel: $100-$300 — best for small to medium sheds. Place 4-inch solid blocks on compacted gravel at each corner and every 4 feet. Easy to level and allows airflow underneath.
- Gravel pad with timber frame: $300-$800 — 4 inches of compacted gravel with pressure-treated 4x4 or 6x6 timbers. Excellent drainage and moderately easy to build.
- Concrete slab: $1,500-$3,000 — best for large sheds and workshops. Provides the most stable, permanent foundation. Use our Concrete Calculator to determine how many yards you need.
- Concrete piers: $200-$600 — poured concrete in sono tubes below frost line. Required in areas with freeze-thaw cycles for sheds over 200 sq ft.

Permits and Setback Requirements
Permit rules vary widely by jurisdiction. Here are general guidelines:
- Under 120 sq ft: No permit needed in most areas, but setbacks still apply
- 120-200 sq ft: Many cities exempt, some require permits — check locally
- Over 200 sq ft: Almost always requires a building permit ($50-$500)
- Typical setbacks: 5-10 feet from property lines, 15-20 feet from other structures
- HOA restrictions: May limit size, height, material, and color — review covenants first
Adding Electrical to Your Shed
If you plan to use your shed as a workshop or office, electrical service is essential. Budget $1,500 to $4,000 for a licensed electrician to run a sub-panel from your main panel.
- 60-amp sub-panel: $800-$1,500 (enough for lights, outlets, and small tools)
- 100-amp sub-panel: $1,200-$2,500 (for heavy power tools, AC, or heat)
- Trenching: $3-$8 per linear foot for underground conduit (required by code)
- Interior wiring: $200-$500 for circuits, outlets, switches, and lighting
