Monroe Township (Middlesex County), NJ Sign Regulations: Window Signs (2026)

Section 108-10.1 is the sign article of the Township Code, and subsection F lists signs permitted in any zone in the Township without a permit. Item (12) covers window signs in two sentences. First, temporary signs or other advertising materials attached to a window must be removed at the expiration of the event for which they were erected or posted. Second, no more than 20% of the square footage of any single window or single window display area can be devoted to signs or other advertising material attached to it or otherwise exposed to public view. The measure is per window or per window display area, so a storefront with several panes is tested one window at a time.

The code defines a sign as any outdoor display or advertising on real property within public view that is intended to attract, or does attract, the attention of pedestrians or vehicle operators. The window rule uses the same public view test, which is why material hung behind the glass but visible from outside counts toward the 20% figure.

Other parts of § 108-10.1 still apply to a window display. Under subsection A(1), any signs not specifically permitted are prohibited. Subsection A(2) bars any sign located so as to materially impede the view of any street or intersection. Subsection G(11) prohibits signs obstructing doors, fire escapes or stairways or keeping light or air from windows used for living quarters. Subsection G(2) prohibits signs using blinking, flashing, vibrating or flickering lighting, and G(3) prohibits signs using outside neon lights or any material which sparkles or glitters. Permanent signs elsewhere on the building need a sign permit from the Department of Planning and Zoning, renewable annually from May 1 through April 30 under subsection B(1)(a).
