Summary

Onslow County's Master Sign Plan standard limits window signs to five per tenant, with total window signage capped at ten percent of a storefront's ground-floor window area. It is the one numeric window-sign limit written into the county's sign article, applied to businesses that adopt an approved Master Sign Plan.

These county ordinances apply to unincorporated areas of Onslow County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Full Breakdown

4 establishes the Master Sign Plan as an alternative to the standard permanent-signage rules in Article 12, letting a development substitute a coordinated, architecturally integrated sign package for the district-by-district freestanding and wall-sign standards elsewhere in the article. 4(C)(1)(c), sets window signs at up to five per tenant, with no maximum height (marked N/A, consistent with a sign mounted flat against glass) but a coverage cap of ten percent of the ground-floor window area. The same table caps awning signs at 15 square feet per tenant per street frontage, freestanding signs at 200 square feet base area (rising to 300 with additional tenants), and front-elevation wall signs at one square foot per linear foot of building wall, so the window-sign line sits inside a broader coordinated package rather than standing alone.

Because the plan is an architectural-theme alternative, freestanding sign structures must use materials and colors related to the principal building and sign copy is limited mainly to name, logo, and address; the Zoning Administrator reviews and approves the Master Sign Plan application, including its signage plan and site plan, before any of these substitute standards take effect. 1(E)(1)(d).

Violations & Fines

No specific fine attaches to Section 12.4 itself, so the general penalty in Onslow County Code of Ordinances Section 1-6 controls: exceeding the five-sign or ten-percent window coverage limit adopted in an approved Master Sign Plan, or displaying signage inconsistent with the approved plan, is punishable by a fine of up to $500.00 or imprisonment for up to six months, with each day of continuing violation treated as a separate offense.

Frequently Asked Questions

How many window signs can a business display in unincorporated Onslow County?
Under Table 12-1 of an approved Master Sign Plan, a tenant may display up to five window signs, and their combined area cannot exceed ten percent of that tenant's ground-floor window glass, per Code of Ordinances Section 12.4(C)(1)(c).
Is the window sign limit automatic for every business?
It applies to properties operating under a Zoning Administrator-approved Master Sign Plan, the coordinated alternative signage track set up in Section 12.4. Businesses outside that plan are still bound by Article 12's general prohibitions, such as the bar on signs blocking windows or exits.
Does the county limit how tall a window sign can be?
No. Table 12-1 lists the maximum sign height for window signs as N/A, since the coverage percentage and per-tenant count, not a height figure, control how much window space a sign package can occupy.
