When a permit is required
Permit triggers and exempt work for Kent County
A permit is required for new construction, additions, alterations, repairs, demolitions, and changes of occupancy. Required for all electrical, plumbing, and mechanical work. Required for accessory structures above the threshold. Required for grading work with land disturbance. Required for all work within the Critical Area buffer unless specifically exempt.
- Exempt One-story detached accessory structures used as tool sheds, playhouses, or similar, provided the floor area does not exceed 200 square feet (Kent County reported threshold; confirm current with department -- state IRC threshold is 120 sq ft, local thresholds vary)
- Exempt Ordinary repairs that do not involve structural changes, additions, alterations, or modifications of any electrical, gas, mechanical, or plumbing system
- Exempt Painting, papering, tiling, carpeting, cabinets, countertops, and similar finish work
- Exempt Prefabricated above-ground swimming pools less than 24 inches deep and used with a listed pump and filter system (confirm current threshold)
- Exempt Fences not exceeding 6 feet in height (confirm; fences in Critical Area may require review)
- Exempt Retaining walls not over 4 feet in height measured from bottom of footing to top of wall, unless retaining a surcharge or adjacent to a public way
Note: Critical Area work is subject to a separate review overlay regardless of building permit exemption status. Any impervious surface addition, vegetation removal, or grading within the Critical Area requires Critical Area review even if no building permit is required. Buildings on farms (excluding residential buildings) are exempt from all inspections except electrical and plumbing.
- Completed building/demolition permit application
- Two (2) sets of construction plans (floor plans, elevations, sections, structural details)
- Site plan showing property lines, setbacks, existing structures, proposed work location, impervious surface calculations, and Critical Area buffer boundary (if applicable)
- Energy compliance documentation (IECC and Maryland energy amendments)
- Contractor MHIC license number and any applicable trade license numbers
- Homeowner owner-builder affidavit (if owner-builder on primary residence)
- Residential fire sprinkler system design documentation (required for new R-3 dwellings)
- Sediment control plan or KCD approval (if land disturbance involved)
- Critical Area worksheet or Buffer Management Plan (if within Critical Area)
- Building code
- 2021 IBC, 2021 IRC, 2021 IPC, 2021 IMC, 2021 IECC, 2020 NEC (NFPA 70), NFPA 1, NFPA 101, all as adopted by the State of Maryland with amendments, plus local Kent County amendments (Bill No. 10-2024 effective 3-4-2025 re: fire sprinklers). eCode360 Chapter 73 (Building Construction): https://ecode360.com/11474555. In any conflict between the codes and the Kent County Land Use Ordinance, the more restrictive provision applies.
- Permit validity
- Permits expire if work does not commence within a reasonable time after issuance, or if work is abandoned or suspended. Exact expiration period per currently adopted IBC/IRC provisions and local code amendments; confirm with department.
- Owner-builder
- Homeowners may pull their own building permits for their primary residence. Trade work (electrical, plumbing, mechanical, gas) typically requires licensed contractors for permit purposes; confirm current owner-builder trade permit rules with the Planning Department.
- Contractor requirements
- MHIC license required for home improvement work on residential structures. Electrical, plumbing, HVAC, and other specialty trades require separate Maryland state trade licenses. Sprinkler contractor license required for residential fire sprinkler system installation. MHIC verification: https://www.dllr.state.md.us/license/mhic/
