Bloomfield, NJ Sign Regulations: Window Signs (2026)

Bloomfield Township sets two tiers of window sign rules in § 315-42, the sign section of the Land Development and Zoning chapter. Permanent window signs for commercial and office uses fall under § 315-42B(3). Window signs cannot cumulatively exceed 20% of the ground floor window area of the establishment, and they cannot reach a height greater than half the height of the window or five feet above the grade outside the window, whichever is lower. Lettering and numbers cannot exceed four inches in height. Doors can carry painted numbers and letters showing the street address, the business name and the hours of operation, also capped at four inches. Window signs count toward the two permissible signs per establishment, while door signs do not.

The definitions in § 315-42A(5) control how a window is measured. A window is a glass area presented to the public for purposes of display, and for glass storefronts made up of multiple window panes, each pane is deemed a separate window.

Temporary window signs are exempt from the sign permit under § 315-42A(6). Civic, cultural and public service posters are limited to one window per establishment and to 20% of the window or five square feet, whichever is less. They can go up no earlier than 60 days before the event and must come down within seven days after it. Promotional or special sales signs are limited to one window per establishment per street frontage and to 50% of the display window or 16 square feet, whichever is less. Each one must show its installation date on the lower right-hand corner as viewed from the exterior and stays up no longer than 30 days. Business opening and change of ownership signs follow the same 50% and 16 square foot ceiling. Both temporary categories are permitted on ground-floor windows only.

Two related prohibitions apply. Section 315-42A(7)(c) restricts neon in a window to advertising a particular product sold by the establishment, with no more than two such signs per street frontage, and A(7)(r) prohibits window signs unless the chapter otherwise permits them. Exposed lighting in or around windows is prohibited under A(9)(h), except for holiday displays and security lighting.
