  • Going DIY saves you roughly $4400 compared with hiring a contractor for the same shed.
  • Pine siding is affordable but should be primed and painted before installation and re-coated every 5-7 years to prevent rot.
  • Most municipalities require a building permit for sheds over 100-200 sq ft. Budget $50-$300 for permits and factor in setback requirements.

Next stepGet at least three quotes from local contractors or lumber yards. Prices can vary by 20-30% within the same metro area.
