What to plan for in Timonium and Lutherville
Lutherville historic district
Lutherville has been a county historic district since 1987. Every property in it is subject to review: the Landmarks Preservation Commission votes on a Certificate of Appropriateness, and all exterior alterations need a county building permit.
Fences, decks and sheds
Inside the district, fences, decks and sheds need a permit at any size. Elsewhere, the county threshold is a deck more than 16 inches high and over 120 square feet, a fence of 42 inches or taller, or a shed over 120 square feet.
Talk to staff early
County historic preservation staff (410-887-3495) can tell you what the Commission will need before you design, which saves a round of revisions.
