Over the years, the City has heard concerns from property owners about the imposition of certain code requirements and how those codes have been applied. In response, City Staff began a process of review and revision of City building regulations in November 2008. We embarked on this effort in order to respond to concerns voiced by elected officials and developers regarding inflexibility of the existing code editions, perceptions regarding the number of local amendments to the codes as onerous, and appeals requesting the City promote base code minimums whereever possible. Staff worked to update the relevant editions of the model base codes used by the City and to prudently examine the appropriateness of various local amendments intended to strengthen those base codes. Most of the codes were two to three editions out of date and many of the local amendments had not been scrutinized for many years.

Additionally, in December of 2008, the City Council unanimously approved the formation of a Building Board of Review. This Board includes local professionals in architecture and building trades to provide an avenue for city staff to seek input on the application of certain laws and codes, particularly as it pertains to historic buildings. It also provides an avenue of appeal to property owners and others who would like to have staff interpretations reviewed.
The code evaluation process involved numerous meetings between members of City Staff as well as hearings before the Building Board of Review throughout 2009. At the conclusion of this process, the Building Board of Review recommended that the City Council adopt the most current editions (2009) of the International Codes, National Electrical Code, and Illinois State Plumbing Code. In addition, the adoption of these codes would reduce the number of local amendments to the International Building Code from 59 to 24 (a decrease of 59%) and the International Fire Code from 65 to 30 (a decrease by 54%). In response to concerns from local homebuilders and the Illinois Association of Realtors regarding the requirement that new single-family homes be equipped with automatic fire sprinkler systems, the City Council referred the matter back to the Building Board of Review for further discussion.
On June 8, 2010, the St. Charles Building Board of Review voted to recommend revision and update of the City’s building code manual and forwarded their recommendation for adoption by the City Council of the following building codes and local City amendments to the same.
- 2009 International Building Code
- 2009 International Residential Code
- 2009 International Fire Code
- 2009 International Fuel Gas Code
- 2009 International Mechanical Code
- 2008 National Electrical Code
- 2004 Illinois State Plumbing Code
The Board further qualified their recommendation as follows:
- The new code provisions will become effective September 1, 2010;
- The requirement in the International Residential Code for residential fire sprinkler systems shall be deferred until January 1, 2012.
The City Council adopted the recommendations of the Building Board of Review on July 19, 2010 and the new codes (except the sprinkler requirements) will go into effect on September 1, 2010.
The most debated aspect of this proposal was the requirement to install automated fire sprinkler systems in new single family homes and 2-unit dwellings. This requirement does NOT apply to existing homes, even if additions or alterations are undertaken. This is directly out of page 62 of the 2009 International Code. It is repeated twice, once for townhouse and one for 1 and 2 family dwellings.
“An automatic residential fire sprinkler system shall not be required for additions or alterations to existing buildings that are not already provided with an automatic residential sprinkler system.”
While I cannot predict what the future will hold (a new set of model codes is anticipated in 2012), at the present time, there are no plans to mandate these systems for existing residential buildings with less than 2 units.
In addition, the Council directed City staff to develop an ordinance to require homebuilders to present an option for homebuyers to have a sprinkler system installed. This requirement (commonly referred to as a “mandatory option”) will apply to all 1 and 2-family homes constructed between now and Janaury 1, 2012.
