Do I Need a Permit to Build a Shed or Outbuilding? in Polen
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
Polish law (Prawo budowlane) exempts certain small structures: free-standing buildings up to 35 m² with a max height of 5 m (flat roof) or 4.8 m (gable) on plots over 500 m² require only a zgłoszenie (notification), not a full permit. Structures exceeding these thresholds or on smaller plots require a pozwolenie na budowę. Any electrical or plumbing connections add their own notification requirements.
