Why You Need a Sign Permit
In Aurora, Illinois, your Sign Permit is mandated by the city's local building and zoning ordinances, which administer and enforce the Illinois State Building Code (410 ILCS 25) for construction. The specific requirements are detailed in the Aurora Zoning Ordinance (Chapter 46), which governs the size, height, illumination, placement, and structural safety of all commercial signage. Issued by the Aurora Building & Permits Division, this permit verifies that your sign design complies with these structural, electrical, and accessibility (per the Illinois Accessibility Code) standards, ensuring public safety and adherence to local aesthetic guidelines. Without it, your sign installation is considered unpermitted construction.
The consequences of installing a sign without this permit are immediate and costly. Based on the city’s enforcement protocols, violations typically trigger:
- Stop-work orders that halt all installation, leaving you with unfinished work and contractual disputes.
- Daily fines until compliance is achieved; while specific amounts vary, municipalities often levy penalties per day of violation.
- Denial of a Certificate of Occupancy or business license, preventing your restaurant from opening.
- Required demolition of the non-compliant sign at your expense, resulting in total loss of materials and labor.
- Lease and insurance complications, as many agreements require all construction to be permitted and inspected, potentially voiding coverage or violating lease terms.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of 2026, Aurora has integrated its permit review processes more fully into a digital portal, though in-person submissions for complex sign designs may still be required; always verify the current submittal method with the Building & Permits Division.

14 of 17 auto-filledLegal Business/Property Owner Name
textEnter the full legal name of the business or property owner exactly as it appears on your Articles of Incorporation/Organization or the property deed; if the owner is an individual, use their full name.
COMMON MISTAKE: Entering a DBA (Doing Business As) name instead of the legal entity name, which will cause a name mismatch and delay processing.
Business License Number
textProvide your current Aurora Business License number issued by the Aurora City Clerk's Office; you must have this license before applying for a sign permit.
COMMON MISTAKE: Leaving this field blank because you haven't obtained your Aurora business license yet; your sign permit application cannot be processed without it.
Sign Installation Address
textUse the exact street address where the sign will be physically installed, which must match the address on your business license for on-premise signs.
COMMON MISTAKE: Using a P.O. Box, the corporate headquarters address, or a different branch location, which violates Aurora's requirement for on-premise signage.
Property Zoning Classification
textEnter the official zoning district code (e.g., B-2, M-1) for the property, which determines your sign's size and type eligibility; find this on your property's plat of survey or the city's zoning map.
COMMON MISTAKE: Guessing or entering an incorrect zoning classification (like 'Commercial'), which leads to immediate denial because sign allowances are zoning-specific.
Property Ownership Status
textState whether you are the 'Owner' or 'Tenant' of the property; if you are a tenant, you must check the 'Landlord Authorization Obtained' box and provide proof.
COMMON MISTAKE: Tenants failing to check the landlord authorization box, which is a mandatory requirement for non-owners under Aurora Zoning Ordinance § 46-704.
Landlord Authorization Obtained
checkboxCheck this box ONLY if you are a tenant, confirming you have written permission from the property owner to install the sign; you must attach the authorization letter.
COMMON MISTAKE: Tenants not checking this box or owners incorrectly checking it, both of which will cause the application to be marked incomplete and returned.
Sign Type
textSpecify the exact category per Aurora code, such as 'Wall Sign', 'Freestanding/Pole Sign', 'Awning Sign', or 'Window Sign'; check the ordinance for permitted types in your zoning district.
COMMON MISTAKE: Using generic terms like 'Neon Sign' or 'LED Sign' instead of the structural type defined in the code, leading to a request for clarification and delay.
Sign Location on Property
textDescribe the precise placement (e.g., 'Mounted on south-facing wall, 10 feet above grade' or 'Freestanding sign 5 feet from property line on Main St. frontage').
COMMON MISTAKE: Vague descriptions like 'on building' or 'in front', which fail to demonstrate compliance with setback and placement rules, triggering a plan review hold.
Sign Dimensions (Height x Width)
textProvide dimensions in feet and inches (e.g., '4 ft. x 8 ft.'), which must not exceed the maximum area allowance for your zoning district and sign type.
COMMON MISTAKE: Providing dimensions in metrics only (e.g., '1.2m x 2.4m') or exceeding the maximum square footage allowed, which is a direct code violation and cause for denial.
Sign Materials and Construction
textList primary materials (e.g., 'Aluminum cabinet with vinyl faces', 'Plywood with routed letters') and mounting method to ensure structural safety compliance.
COMMON MISTAKE: Omitting this detail or listing only the finish (e.g., 'red paint'), which can stall the review until engineering or material specs are provided.

Top 5 Sign Permit Mistakes
1. Submitting Incorrect or Incomplete Sign Specifications
Applicants often list approximate dimensions instead of exact measurements or omit required technical details like sign materials and illumination type. For example, entering 'about 4 feet tall' instead of '4 feet 3 inches (51 inches) in height, internally illuminated channel letters with LED modules.' This mistake leads to immediate rejection or a 'more information needed' hold, adding 2–3 weeks to your timeline while the city's Planning & Zoning Division requests corrections. Based on ApronPrep's analysis of Sign Permit applications in Aurora, over 60% of initial rejections stem from inaccurate or incomplete specifications on the application form.
2. Failing to Provide the Required Site Plan and Elevation Drawings
A common error is submitting a basic sketch instead of a to-scale, professional site plan showing the sign's exact location, setbacks from property lines, and relationship to buildings and parking. Aurora's Municipal Code § 51-156 requires a dimensioned site plan and elevation drawings. Applications missing these engineered drawings are deemed incomplete and will not be processed, causing a 1–2 week delay while you commission new plans. Always ensure your drawings include a north arrow, scale (e.g., 1/8" = 1'), and clearly mark all property lines and building footprints.
3. Misstalling the Sign Owner or Business Entity Information
Confusion arises over whether to list the property owner, business tenant, or sign contractor as the 'applicant' or 'owner of sign.' The Aurora application requires the legal property owner's name and signature for consent. A typical mistake is the tenant filling out the form without the owner's authorization, or listing the DBA ('Joe's Diner') instead of the registered LLC name. This discrepancy triggers a legal review stop, adding 5–10 business days for verification. The correct entry is the property owner's legal name as it appears on the deed or tax records, with their notarized signature if required.

Obtain sign permit application form from City of Aurora Property and Business Division
Download the 'Sign Permit Application' (Form SPD-1) from the City of Aurora's online Permit and Development Portal. If applying in person, forms are available at the Property and Business Division office at City Hall. Have your business address and preliminary sign design dimensions ready to reference.
Complete application with all required information and sign specifications
Fill out all sections of the SPD-1 form, including detailed sign specifications: exact dimensions, materials, colors, illumination type, and structural attachment method. You must provide a site plan showing the sign's proposed location and a scaled drawing of the sign design. Applications missing the scaled drawing are the most common cause of immediate rejection.
Submit application to the Division of Property Standards or Permits office
File your completed application packet (form, site plan, and drawings) through the online portal or in person at the Permit Counter. Online submission is recommended to avoid mail delays.

See All RequirementsThe Aurora Development Services Department estimates a processing timeline of **5-10 business days** for most standard sign permit applications, per their published application guide. This timeline starts once a complete application with all required documents is submitted. Keep in mind that reviews for larger or illuminated signs, or applications submitted near a project requiring a Building Permit, may take longer.
According to the City of Aurora fee schedule, the government filing fee for a standard sign permit application is **$0**. This is because permit fees are calculated based on the sign's construction value and are assessed upon approval, not submission. Contact Aurora Development Services to confirm the final assessed fee for your specific sign project, as it will be based on the valuation of materials and installation work submitted with your plans.
No, sign permits in Aurora are **site-specific and non-transferable**, as stated in the city's zoning ordinance. A permit issued for one address cannot be used for a sign at a different location. If you move your business, you must submit a new application for the new address, which will be reviewed against the zoning and sign regulations for that specific property. This is similar to the site-specific approval process for a Certificate of Occupancy.
Sign permits in Aurora are typically **issued for the life of the sign structure** and do not require periodic renewal, provided the sign is maintained in compliance with the original permit. However, any proposed modification to the sign's size, illumination, structure, or message (for changeable copy signs) requires a new permit application. Annual renewals are required for other city licenses, such as the City Business License/Registration.
A city inspector will visit the site to verify the sign is installed **exactly as shown on the approved plans**, checking for compliance with the Aurora Zoning Ordinance. They will confirm the sign's dimensions, height, location, structural integrity, and electrical safety (if illuminated). Passing this final inspection is required before the sign can be legally operated. Not legal advice — verify specific inspection protocols with the Aurora Development Services Department.
