Update: The Clean and Affordable Buildings Ordinance (CABO) was sent to the rules committee today, 1/24/24. It will need 26 votes to be re-referred to the environmental protection and energy committee. [Per Heather Cherone]
Name: Clean and Affordable Buildings Ordinance (CABO)
Purpose: Improve indoor air quality, reduce heating costs, and reduce the city’s contribution to climate change
Mechanism: By amending the Chicago Construction Codes, new construction residences would not be able to have most types of combustion  used as the source of energy for cooking, water heating, and space heating .
The bulk of the code amendment is shown below.
This follows a previous building code amendment that required that any new construction housing built with combustion appliances also has the necessary electricity infrastructure – like higher amp circuits and higher voltage outlets – to enable swapping appliances for electric-only models. The Chicago Energy Transformation Code took effect November 1, 2022.
Many buildings are already being built all-electric because of the cost savings for builders and tenants, simpler designs, and the desire by some tenants to have cleaner indoor air. ComEd has an electric homes program that pays builders up to $5,000 per unit for going all-electric.
I believe that most tenants will realize at least a small improvement in their living arrangements by moving from a place that uses gas for heating and cooking to a place that is all-electric. In fact, I think they will ultimately appreciate the lower energy costs – the most significant cost change is the lack of a $30-50 monthly customer charge from Peoples Gas.
Additionally, much of the costs of buying and installing electric appliances in new construction homes (and renovated homes) is being subsidized by the Inflation Reduction Act.
The ordinance’s next steps are to be assigned to a City Council committee, passed out of that committee, and passed out of City Council. The ordinance’s standards would be effective 12 months after passage and apply to building permit applications filed on and after that date.
 Appliances that use a fuel source that when combusted emit less than 25 kilograms of CO2 per million BTU would be permitted, as would the combustion of wood in a fireplace or for cooking purposes.
 Combustion fuel used for “emergency and standby electricity” is excepted.
