Do I Need a Permit to Build a Shed or Outbuilding? in Verenigde Staten
Whether you need a permit for a shed depends on its size, height, and location. Most US jurisdictions exempt sheds under 120–200 sq ft without electrical or plumbing, but setback and HOA rules still apply. In Europe, small garden structures are often permit-free below a size threshold, but anything with a foundation, electricity, or plumbing usually requires at least a notification.

Country-specific detail
Most US jurisdictions exempt accessory structures under 120–200 sq ft that sit on skids or blocks (no permanent foundation), have no electrical or plumbing, and meet setback requirements. Larger sheds, any shed with utilities, and sheds on permanent foundations require a building permit. HOA covenants may impose additional restrictions on size, style, or placement even when the city doesn't require a permit. Always check both the municipal building code and HOA rules before construction.
