Interior Remodeling - Residential

This guideline has been developed to identify the minimal submittal requirements for a permit application to remodel the interior a single-family residence. The information provided contains, and is not all-inclusive to, the City of Wheaton’s adopted Building Codes, Ordinances, and inspections required for this type of project. Please review this information and call the phone numbers provided should you have any questions.

Required Submittals
The following documents, forms, and/or permits must be submitted prior to plan review. Referenced forms are available on the Building and Code Enforcement website and can be accessed throughout this document by following the appropriate link.

  1. Application for Permit
    When filling out the application for permit, include all required information that is pertinent to the proposed scope of work such as; site address, description of work, contractors to be used on the job and their respective costs per trade, the total cost of work to be performed, complete applicant contact information, etc. Please refer to document titled Building Application for Permit.
  2. Architectural Plans
    Please submit two (2) complete sets of architectural plans and any other required documentation that will be necessary to complete the review of the construction documents.
  3. Contractor Registration - See Contractor Registration Guidelines & Contractor Registration Application
  4. Combustion Air Calculation Worksheet
    Fill this form out only if adding a new furnace or hot water heater and/or constructing a room around an existing furnace or hot water heater. Please refer to document titled Combustion Air Calculation Worksheet for additional information.
  5. Water Service Line - Sizing
    This form must be completed only if you are adding any additional plumbing fixtures to the residence. The Illinois State Plumbing Code has specific requirements as to how many fixtures within a residence can be served by specific water service sizes. Please refer to document titled Water Service Line - Sizing. This form will calculate the proposed “fixture count” for your home. Please submit this completed form and a site plan indicating the required minimum 10' separation between the proposed service and the existing sanitary service with your building plans. After this form is then submitted to the Building Department, it will be forwarded to our Water Department to determine the required size of the water service for your house. Based on their records, they will determine if either the existing water service line for your home is adequate in size to remain in compliance with State law, or if the water service line from the main to the house needs to be replaced with a larger diameter water service. There is a variance process that can be pursued to obtain a waiver for a required water service upgrade through the State of Illinois regulations. You may call our Water Department at 630-260-2090 should you need additional information.

Architectural Plan Requirements
The construction documents shall be prepared, signed, and sealed by a registered Illinois Design Professional for all structural and load-bearing adjustments.

Current Codes - Building
See the document titled Current Codes that identify codes that may be applicable to your construction project.

Significant Codes - Building
Demolition and Construction Regulations
During construction, it is important that you inform your workers to abide by the Codes and Ordinances of the City of Wheaton, especially those that are identified in the Demolition and Construction Regulations guideline.

Smoke Alarms
The 2012 International Residential Code requires that Smoke Alarms are required to be installed within each sleeping area, in the hallway directly adjacent to sleeping areas, and one per floor minimum (including the basement). The Smoke Alarms are all required to be powered by a commercial power source, interconnected so that the activation of one alarm will activate all of the alarms, and each alarm must have a battery backup. (2012 IRC R314 - Smoke Alarms)

Heat Detectors
Heat Detectors are required to be installed in any attached garage. The heat detector shall receive primary power from the building wiring, and when primary power is interrupted, shall receive power from a battery. The heat detector shall be interconnected with the smoke alarm system in such a manner that activation of one alarm will activate all of the alarms in the individual unit.

Carbon Monoxide Detectors
Per State of Illinois requirements, Carbon Monoxide Detectors are required to be installed outside each separate sleeping area in the immediate vicinity of the bedrooms. The detectors must be installed per manufacturer specifications and must be in place at the time of the Final Inspection.

Egress Windows
The 2012 International Residential Code requires that each sleeping area must have a minimum of one egress window located within the room. Basements with habitable space are also required to have at least one emergency egress window. The required specifications for Emergency Egress Windows are as follows:

  • Minimum 5.7 square feet clear opening with the normal operation of the window
  • Minimum clear opening height of 24”
  • Minimum clear opening width of 20”
  • Maximum sill height of 44” above the finished floor
  • No special knowledge, hardware or equipment required to operate the window
  • A basement egress window requires a minimum 3’x3’ clear area within escape well. If the escape well is greater than 44” below grade in-depth, a permanent ladder must be mounted to the side of the window well. (2012 IRC R310 –Emergency Escape and Rescue Openings)

Overhead Sewer
As per Wheaton Ordinance, for any new, remodeled, or enlarged basements Overhead Sanitary sewer service is required. The entire basement must be served by this system. Please indicate the proposed location for the sanitary pit on the required plumbing plan diagram. (Wheaton Ordinance F-0686; Section 22-10 Wheaton Municipal Code).

Insulation Requirements
The 2015 International Energy Conservation Code states that the following R-values are required for the specific structural elements that are listed as required to be insulated:

  • Exterior Walls - R-20
  • Ceilings separating conditioned spaces from unconditioned spaces, as well as Cathedral Rafters - R-49
  • Crawlspace Walls (Continuous Encapsulated Blanket) - R-15
  • Crawlspace Walls (Cavity Installation) - R-19
  • Unfinished Basement Walls (Continuous Encapsulated Blanket) - R-10
  • Unfinished Basement Walls (Cavity Installation) - R-13
  • Floors above unconditioned space - R-30
  • Ductwork running through attic spaces - R-8
  • Ductwork running through other unconditioned spaces - R-6

The method for obtaining these R-values must be specifically indicated on the plans. These R-values must be obtained independently of any other structural components other than the insulation itself. Exposed insulation must have a flame-spread index not to exceed 25 and an accompanying smoke-developed index not to exceed 450. The vapor barrier is to be installed on the warm side of the perimeter wall. (2012 IRC R702.7; Wheaton Ordinance)

Combustion Air Calculation
The 2012 International Residential Code requires that anytime gas-fired mechanical equipment is placed in a confined space or within a structure deemed of “unusually tight construction, makeup combustion air that is obtained exclusively from the exterior of the structure must be provided to allow for the proper operation of the mechanical equipment. Please see the document titled Combustion Air Calculation Form in order to determine the required size of each of the supply vents (one opening must be within 12” of the ceiling, the other within 12” of the bottom of the enclosure) that must be installed. (2012 IRC G2407 - Combustion Air)
