The following sections of the International Residential Code,, as adopted in Section 1422.01, are hereby amended as follows:
Any reference to the International Plumbing Code shall be replaced with Illinois Plumbing Code, current edition.
Any reference to the International Electrical Code shall be replaced with 2005 National Electric Code.

Section R101.4 Workmanship. (Added) All work shall be constructed, installed and completed in a workmanlike and acceptable manner so as to secure the results intended by this code. Where recognized standards of workmanship have not been established, they shall be applied to the work being performed. Where standards of workmanship have not been specifically established, the rule of reasonable expectations of a reasonable person shall apply.
The code lacks language for workmanship. Work can be installed poorly but still meet code requirements. This language will provide residents protection from poor workmanship.
Section 102.5 Appendices. Add Appendices A Sizing and Capacities of Gas Piping, Appendix B Sizing of Venting Systems Serving Appliances Equipped with Draft Hood, Category I Appliances and Appliances Listed for Use with Type B Vents, Appendix C Exit Terminals of Mechanical Draft and Direct-Vent Venting Systems, and Appendix D Recommended Procedure for Safety Inspection of Existing Appliance Installation, Appendix G Swimming Pools, Spas and Hot Tubs, Appendix H Patio Covers, Appendix J Existing Buildings and Structures, and Appendix K Sound Transmission are specifically adopted by Village of Richton Park and shall apply.

Section 105.5 Expiration. Add after “the time the work is commenced.” “Building permits expire one-year from the date of issuance. New submittal is required if the permit expires without the benefit of an extension.
Places expiration date on the building permit. Previous code editions did not. Prevents structures from sitting idle. Removes ambiguity that currently exists which allows permit to remain active for a rolling 180 days so long activity has taken place on the site, no matter how small.
Section R106.1 Submittal documents. Amend to read: Construction documents, special inspection and structural observation programs, and other data shall be submitted in three sets with each application for a permit. The construction documents shall be prepared by a registered design professional, registered in the state. Where special conditions exist, the building official is authorized to require additional construction documents to be prepared by a registered design professional. All truss design drawings shall be submitted at the time the permit is issued.
Requires construction documents and plans to be prepared by registered design professional registered in Illinois. Current code requires jurisdictional statute to enforce.
Section R106.2.1 Plats required. (Added) New construction requires, top of foundation plat with elevation of walls and set back requirements per Village zoning code. This plat shall be submitted and reviewed after the foundation walls are set and prior to further construction. The TOF shall match those submitted in the subdivision development plan. A final plat of survey showing conforming TOF and final topography shall be submitted and approved by village engineer prior to issuance of certificate of occupancy.
Chapter 2 Definitions. Add “Bedroom: A private room planned and intended for sleeping, separated from other rooms by a door. A bedroom will have windows, closet and is physically separate from other rooms.”
This language helps properly define a bedroom so proper egress is met, smoke and carbon monoxide detectors are installed and correct impact fees are imposed.
