Summary
Cecil County deleted the International Building Code's standard exemption for small sheds. Under § 157-2 of the Code of Cecil County, one-story detached accessory structures used as tool sheds, storage sheds or playhouses no longer qualify for the usual under-120-square-foot exemption from a building permit, so a permit from the Division of Permits and Inspections is required regardless of size.
Section 105.2 Work exempt from permit. (a) Delete 1: "One story detached accessory structures used as tool and storage sheds, playhouses and similar uses, provided the floor area does not exceed 120 square feet (11 m2)."
Full Breakdown
Chapter 157, Building Construction, adopts the 2021 International Building Code and International Residential Code as amended by the County Council. 2, Work exempt from permit, and specifically deletes exemption item 1, which in the unmodified IBC lets a one-story detached accessory structure used as a tool shed, storage shed, playhouse or similar use skip a permit if its floor area is 120 square feet or less. With that exemption struck, Cecil County requires a building permit from the Division of Permits and Inspections for a detached shed or similar accessory structure no matter how small its footprint.
The same amendment package adds two exemptions the county does allow without a permit: replacing or repairing roofing shingles, membranes or flashing that involves no structural work, and replacing windows or doors of the same dimensions that involves no structural work. Once issued, a permit stays valid for one year from issuance provided work is ongoing, with up to two six-month extensions available under § 157-2A(7) before a renewal permit is required. Permits are reviewed by the Division of Permits and Inspections, and any structure built in a floodplain must also satisfy the Floodplain District standards of the separate Cecil County Zoning Ordinance, Article XI, Part III.
Homeowners planning even a small tool or storage shed on unincorporated county land should apply before construction begins; skipping the permit exposes the owner to the stop-work and civil-penalty provisions of § 157-9.
Violations & Fines
Building without the required permit is enforced under § 157-9: a violation carries a civil fine of up to $1,000 or up to 90 days' imprisonment, plus the county's abatement costs and attorneys' fees, and the Code Official may issue a stop-work order; continuing work after a stop-work order adds a separate fine of $250 to $1,000 per day.
