Mount Prospect, IL Building Safety: Green Building Code (2026)

Section 14.317 of the Village of Mount Prospect zoning chapter is titled Environmentally Sensitive Development Techniques. Its opening statement says the Village is committed to encouraging these techniques to improve quality of life and environmental health, and defines green building design as a technique that limits the energy demands of buildings and creates healthier living environments within them.

The listed techniques are green roofs, reflective white roofs, permeable paving, stormwater harvesting, use of landscaping to reduce thermal demand, and use of reusable energy sources. The section calls itself direction on common practices, not a comprehensive list, and says the Village encourages property owners to follow green design principles. The introductory language is encouragement, not a requirement.

The binding standards appear in the subsections that follow. Wind energy conversion systems need a conditional use permit, which is allowed in all zoning districts. No more than one system is allowed per zoning lot unless the Village Board approves more for commercial or industrial property. Rooftop units must be set back at least twenty feet from front or exterior building lines and ten feet from side building lines, and cannot rise more than fifteen feet above the roof peak or parapet. Tower mounted units are not permitted in single-family districts, cannot exceed eighty feet, and cannot continuously exceed 65 decibels at the property line.

Solar energy conversion systems are permitted in all zoning districts under their own minimum standards, and electric vehicle charging stations carry location, signage, parking, screening and equipment protection standards. Those rules are covered on their own pages.
