  • Retaining walls 4 feet or less that do not support a surcharge do not require a building permit under the adopted IRC/IBC Section 105 exemptions.
  • Sheds up to 200 sq ft (residential, per the shed structure definition) may not require a Building Permit — a Zoning Permit Application is used instead; sheds over 200 sq ft or taller than one story require a full Building Permit as an accessory structure.
