Quick answer
Authority: the New Castle County Department of Land Use issues building, plumbing and mechanical permits only for UNINCORPORATED New Castle County (Chapter 6 applies to the unincorporated territory plus municipalities that elect in). Per Chapter 6 Appendix 6 (FY2026), Wilmington, Newark, Middletown, New Castle (city), Elsmere, Delaware City, Newport, Odessa and Townsend run their own building inspection and plan review and are excluded; the County does provide it for Ardencroft and Bellefonte. Electrical work is not permitted or inspected by the County at all: it goes through the State of Delaware (licensed electrical inspection agencies, or a State homeowner permit). In the unincorporated county, ordinary residential fences are exempt from permitting; the one exception is a fence that serves as a swimming pool barrier. Fences must still meet UDC 40.03.410: generally no more than 6 feet tall (4 feet in the street yard in NC5, NC6.5, NC10 and NC15 districts) and approved materials only.
Typical threshold: Only fences that serve as swimming pool barriers need a permit.

What a fence permit costs in New Castle County
How to apply in New Castle County
In New Castle County, most residential fences fall under the model code's 7-foot building-permit exemption, so the real approval step is a lightweight zoning or land-use permit built around a simple site plan showing the fence's location, height, and material, checked against setbacks and any corner-lot sight-triangle rule. A fence that will serve as a required swimming-pool barrier is the exception, since barrier fences carry life-safety requirements of their own.
What most fence permit applications include:
- For New Castle County, a fence 7 feet or under is exempt from the model code's building permit, the same threshold the IRC uses for other small projects (IRC 2021 R105.2).
- That exemption only removes the building-code permit. It does not authorize skipping a jurisdiction's own zoning approval, which is why an exempt fence can still need its own land-use or zoning permit rather than a building permit (IRC 2021 R105.2).
- Whatever your jurisdiction calls that approval, the application centers on a basic site plan: a drawing of the property showing the fence's location, height, and material, and how it relates to the property lines (common local zoning practice).
- For New Castle County, the same plan is checked against required setbacks and, on corner lots or near intersections, a sight-triangle rule that caps fence height so it does not block sightlines for drivers (common local zoning practice).
- For New Castle County, a fence that will serve as a required swimming-pool barrier is handled as life-safety work rather than the light zoning process, and at least one state's adopted residential code requires a building permit for barrier fences regardless of the general fence exemption (Oregon Residential Specialty Code 2021, R101.2.2).

Inspections and closing out your permit
In New Castle County, inspection follows the permit: a fence that never needed one gets no inspection at all under the model code, and a permitted fence typically gets a single final check rather than the staged inspections used for a house. The exception is a fence serving as a swimming-pool barrier, which gets its own dedicated barrier inspection covering height, gaps, and gate hardware.
- In New Castle County: inspection duty attaches only to work for which a permit is required, so a fence that qualified for the permit exemption carries no inspection obligation under the model code (IRC 2021 R109.1).
- In New Castle County: where a fence permit was issued, the process skips the staged foundation, frame, and rough-in inspections used for buildings and goes straight to one final inspection once the fence is finished (IRC 2021 R109.1.6).
- In New Castle County: that single check is typically a zoning compliance inspection rather than a structural review, confirming the fence matches the approved height and site plan (common local practice).
- A fence built as a swimming-pool barrier breaks that light-touch pattern in New Castle County: it is separately inspected for barrier compliance, commonly required before the pool itself can be signed off (ISPSC 305; local pool-barrier inspection programs).
- In New Castle County: that barrier inspection checks dimensional rules from the swimming pool and spa code rather than ordinary fence rules, including the minimum 48 inch barrier height and limits on openings and gaps a young child could pass through (ISPSC 305).
- Gate hardware is inspected too in New Castle County: a self-closing, self-latching gate is part of the barrier requirement, since an unlatched gate defeats the fence's purpose as a barrier (ISPSC 305).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the New Castle County permit portal or by phone at 302-395-5400.
