Porter County, IN Sign Regulations: Window Signs (2026)

The Porter County Unified Development Ordinance regulates window signage separately for each of its eight sign districts (SI-01 through SI-08). 53 SI-08): a single window sign may not exceed twenty square feet or thirty percent of the window's glass area, whichever is smaller, may not stand taller than five feet, and is limited to one per facade and three per building. 52 SI-07) doubles the allowance to forty square feet, raises the height ceiling to seven feet, and permits two window signs per facade instead of one.

48 SI-03 are limited to entry feature signs only, with no window-sign allowance. Every permanent window sign, in any district, must be shown on an elevation drawing attached to the Sign Permit application, and relocating or modifying an installed sign requires a brand-new permit rather than an amendment to the old one. 46 SI-01(A) mandate applies here too: a Sign Permit is required for all signs covered by Chapter 5's Sign Standards unless a specific exemption applies. The UDO's stated effective date is June 15, 2007, so these figures should be checked against any amendment adopted since then before relying on them for a current permit application.
