Frequently Asked Questions
How much does a garage conversion cost in Illinois?
Basic conversions for offices or gyms typically range from $10,000 to $25,000. Full living space conversions (ADUs) with plumbing and HVAC average between $50,000 and $100,000 depending on local labor rates and material choices.
Do I need a permit for a garage conversion in Illinois?
Yes. Any conversion to a 'habitable space' requires a building permit. This ensures the space meets fire safety, ventilation, and energy efficiency standards set by the Illinois Department of Public Health and local building departments.
Will a garage conversion increase my property taxes?
Likely yes. Since a conversion increases the finished square footage of your home, local assessors in counties like Cook or DuPage will typically re-evaluate your property value, which can lead to higher taxes.
Can I convert a detached garage into a guest house in Chicago?
Under the current ADU Ordinance, you can build or convert a detached garage into a 'Coach House,' provided your lot meets specific zoning criteria (RS-2, RS-3, RT, or RM districts) and size limitations (usually capped at 700 sq. ft.).
