Plain-language summary

Written by AI (claude-opus-5-5) from the ordinance text only: SO2026-0024086 Substitute Ordinance.pdf. AI can make mistakes; the official document always wins.

This ordinance changes the dates in Chicago's heating rules for buildings that use the same system for both heating and cooling. Normally, homes must be kept at least 68°F during the day and 66°F at night, and occupied work spaces at least 68°F, from September 15 to June 1. In buildings with combined heating and cooling systems, a lower 64°F minimum is allowed during certain fall and spring periods, and this ordinance adjusts the dates of those periods.

• The regular heating season stays September 15 to June 1 for apartments, sleeping units, and indoor work spaces.
• Buildings that use the same equipment for heating and cooling may keep a 64°F minimum at all hours during set fall and spring windows.
• Fall window: starts September 15 and ends in October (the text lists both October 15 and October 31), before nighttime outdoor temperatures first drop below 45°F.
• Spring window: ends June 1 and starts in spring (the text lists both May 1 and April 1), once daytime outdoor temperatures first go above 75°F. The text does not show which date is being added and which is being removed.
• The change takes effect once it is passed and published.

Who: Residents, workers, and owners of buildings in Chicago that use the same facilities for both heating and cooling are affected.

Where: Citywide (Chicago)
