TL;DR
An accessory structure permit is the building approval required for a detached secondary structure such as a shed, gazebo, or detached garage on a residential lot. Most jurisdictions exempt small sheds, commonly under 120 or 200 square feet, but still enforce setback, height, and lot-coverage limits even when no permit is needed.
What it means
An accessory structure permit is the building approval required for a detached secondary structure such as a shed, gazebo, or detached garage on a residential lot. Most jurisdictions exempt small sheds, commonly under 120 or 200 square feet, but still enforce setback, height, and lot-coverage limits even when no permit is needed. Larger or electrified structures trigger plan review, footing inspection, and sometimes engineered wind or snow-load anchoring. Building an oversized shed without one can force relocation or demolition when the property is sold or inspected.
