The paperwork
What a sign company in Mount Prospect has to get approved
Mount Prospect reviews each sign against its code, and a shopping center adds its own sign rules.
Before a sign goes up in Mount Prospect, the village reviews it against the sign code, and a sign that exceeds the code needs a variation from the Planning and Zoning Commission. Some signs are exempt, including window signs, door-glass signs, sidewalk signs, and flags, so the first question is which type yours is.
SignFreaks handles the sign permits from application through installation, and asks for any shopping center criteria at the survey.
Permit application
Drawings of the sign, its size, and its place on the building or lot go to the village.
Center sign criteria
A shopping center files written sign criteria with the director before tenant signs go up.
Landscaped sign base
A freestanding sign needs landscaping around it equal to twice the size of the sign.
Variation request
A sign outside the code goes to the Planning and Zoning Commission for a variation.

Sign questions from Mount Prospect businesses
What does a sign company in Mount Prospect do?
Where can I buy a custom made sign in Mount Prospect?
You can buy a custom made sign in Mount Prospect from a sign company that handles the permit and the installation along with the fabrication. Buying the sign alone leaves the village review to you.
Do I need a permit for a business sign in Mount Prospect?
Yes, you need a permit for a business sign in Mount Prospect, except for exempt signs such as window, door-glass, and sidewalk signs. A sign over the limits needs a variation. We file the sign permits.
How much does a channel letter sign cost in Mount Prospect?
A channel letter sign in Mount Prospect costs what its letter size, depth, lighting, mounting, and permit path add up to, and the wall changes several of those. A free survey produces a written quote for channel letters.
What is the average cost of a business sign in Mount Prospect?
The cost of a business sign in Mount Prospect has no honest average, because type, size, lighting, and installation change the total so much. SignFreaks quotes after a survey, so the number matches your wall or lot. See monument signs.
Where can I legally put a business sign in Mount Prospect?
A sign company in Mount Prospect reads the limits by sign type, so you can legally put a business sign on your wall within the lesser of 10% of the wall or 150 square feet, or on a freestanding sign up to 75 square feet a face and 12 feet high. Roof, painted, portable, and feather signs are prohibited. See channel letters and monument signs.
Are electronic message center signs allowed in Mount Prospect?
Electronic message center signs fall under their own rules in the Mount Prospect sign code, separate from a standard wall or freestanding sign. We read the current rules and your lot’s zoning before we design one, and file the sign permits.
Can a shopping center tenant put up its own sign in Mount Prospect?
A shopping center tenant can put up its own sign in Mount Prospect, but the center must first file written sign criteria with the village director. We ask for those criteria at the survey. See shopping malls.
How do I get a road sign for my business in Mount Prospect?
You get a road sign for your business in Mount Prospect by ordering a freestanding sign, which is held to 75 square feet a face, 12 feet high, 5 feet from the lot line, with landscaping. See monument signs and pylon signs.
