Single-Family Residence

This informational guideline has been developed to identify the minimal submittal requirements for a permit application to build a new 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 need to be submitted to initiate a review of your project:

  1. Building Permit Application - When filling out a Building 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.
  2. See Contractor Requirements.
  3. Engineering - Application for Permit - Refer to document titled Engineering Application for Permit.
  4. Curb/Driveway Permit Application - Please refer to the document titled Curb/Driveway and Public Walk Permit.
  5. Stormwater Management - See Stormwater Management Application.
  6. Grading Plan Requirements Type II - Please refer to the document titled Grading Plan Requirements Plan Type II for specific requirements Please submit two (2) copies. Please call our Development Engineer at 630-260-2040 should you need further information.
  7. Combustion Air Calculation Worksheet - To be completed only if calculations are not included as part of the building permit. Please refer to the document titled Combustion Air Calculation Worksheet for additional information.
  8. Water Service Line (Sizing) - 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 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. This is a variance process and can be pursued to obtain a waiver for a required water service upgrade through the State of Illinois. You may call our Water Department at 630-260-2090 should you need additional information.
  9. Sewer Permit - The sanitary sewer system in Wheaton drains to and is serviced by the Wheaton Sanitary District or DuPage County, see attached map to determine which agency you will need to contact to obtain a sewer permit from them. Each agency has its own submittal requirements available on their web page, once approved please provide a copy of permit, or copy of the email if "no permit required" from Wheaton Sanitary District, to the Wheaton Building Department.

The 2018 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. (2018 IRC R314 - Smoke Alarms)

Heat Detector
Heat Detectors are required to be installed in any integral garage or 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 the activation of one alarm will activate all of the alarms in the individual unit. Wheaton Ordinance modifying 2018 IRC R314.8

Egress Windows
The 2018 International Residential Code (2018 IRC R310.6; Wheaton Ordinance) 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. When a sleeping room with the required egress window is present in a finished basement, that window is adequate to serve the remaining adjoining non-sleeping room areas of the basement. The specifications 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;

Combustion Air
The 2018 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 refer to 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. (2018 IRC M1703.2, 2018 IRC M1703.2.1 - Combustion Air)

Insulation Requirements

  • Ceilings separating conditioned spaces from unconditioned spaces, as well as Cathedral Rafters: R-49
  • Crawlspace Walls: R-15(Continuous) or R19(Cavity)
  • Basement Walls: R-10(Continuous) or R13(Cavity)
  • Ductwork running through 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.
