Deck Construction · Carroll County, Maryland
In Maryland, a Deck Construction requires a building permit.
The county's own page states directly that deck construction is considered an addition to a home and therefore requires permits and inspections, with no small-deck exemption identified, consistent with Maryland's general pattern of requiring a permit for any deck supported by footings regardless of height. The county's own Deck Guide specifies guardrails of 36 inches are required for any deck surface more than 30 inches above floor grade, and framing and final inspections may be combined into a single visit only if the deck is a minimum of 48 inches above grade. Plans are reviewed under the Carroll County Bureau of Permits and Inspections (unincorpor code (IRC Carroll County Resid); apply through Carroll County Government before work begins.
