Permit takeaway
Howard County states that only decks less than 25 square feet do not require footings or permits, while sheds over 200 square feet require building permits.
Zoning and placement
Deck and shed placement should be checked against zoning, setbacks, easements, and any grading or site conditions before applying.
Building and trade review
Deck footings must meet county depth and size requirements, and sheds larger than 400 square feet require frost footings at least 30 inches below grade.
Call before applying when
Call before applying if the deck is near the exemption threshold, includes stairs or unusual framing, the shed is over 200 square feet, or the property has grading, easement, or septic constraints.
