Do I need a permit for screen enclosure or pool cage in Unincorporated Frederick County?

Permit likely required

Most likely yes. Screen enclosure or pool cage usually requires a permit in Maryland. Confirm the specifics with Unincorporated Frederick County.

A screened porch or enclosure attached to the house, or built on a deck, is treated as a structure under the 2021 IRC; the model deck exemption is narrow (under 200 sq ft, not over 30 inches above grade, not attached, and not serving an exit door) and may be locally amended. Land within 1,000 feet of tidal waters or tidal wetlands is generally in the Chesapeake Bay or Atlantic Coastal Bays Critical Area, where State law caps lot coverage (often 15 percent, or 25 percent on some older small lots) and a separate local critical area review may apply. Local jurisdictions may amend the Standards, and a local amendment prevails where it conflicts (Public Safety 12-504); the county, Baltimore City, or a municipality with its own code office sets the actual permit list. An enclosure attached to the house is a structural addition to the dwelling rather than a freestanding accessory structure. Attached enclosures require a building permit, and the footings and the attachment to the existing structure are normally inspected before they are covered up.
