Thinking about turning that dusty, underused garage into something more functional and beautiful? You’re not alone. More homeowners in Glenview, IL, and throughout the Chicago suburbs are exploring garage conversions as a smart, stylish way to add living space without building an addition from scratch.
As custom home builders in Glenview, IL, we’ve helped families transform garages into everything from cozy bedrooms to sleek home offices and full-on rental apartments. If you’re wondering whether a garage conversion is the right move for your home, here’s everything you need to know—costs, pros and cons, and creative ideas to get inspired.
Why Consider a Garage Conversion?
Let’s face it—most garages are either half-empty or stuffed to the brim with boxes you haven’t opened since 2006. Instead of letting that square footage go to waste, why not convert it into a living space that actually adds value to your home and improves your lifestyle?
Whether you’re craving a private guest suite, a teen’s hangout zone, or a quiet spot to work from home, a garage conversion can be the perfect solution.
Popular Garage Conversion Ideas
1. Garage to Bedroom Conversion
This is one of the most popular choices, especially for multigenerational households. A garage conversion into a bedroom can provide a private, comfortable space for aging parents, returning college kids, or long-term guests. Add an ensuite bathroom and a separate entrance, and it becomes a mini suite with major privacy.
2. Garage to Apartment Conversion
Looking to generate rental income? A garage to apartment conversion is a smart way to create a legal ADU (Accessory Dwelling Unit) in Glenview. With a kitchen, bathroom, and living area, this space can be rented out or used as a self-contained in-law suite.
3. Garage Office Conversions
Remote work isn’t going anywhere. A garage office conversion lets you keep your work life separate from your home life. Think built-in desks, great lighting, and maybe even soundproofing for all those Zoom calls.
4. Garage Conversion to Living Space
Need a family room, playroom, or even a home gym? A garage conversion to living space gives you extra square footage without eating into your backyard. Add heating, cooling, and good insulation, and you’ll never know it used to house your lawn mower.
The Cost of Garage Conversion in Glenview, IL
Let’s talk numbers. The cost of garage conversion depends on several factors: the condition of the garage, the purpose of the space, and the level of finish you’re after.
Here’s a general breakdown:
- Basic garage to bedroom conversion: $25,000–$40,000
- Garage office conversion: $20,000–$35,000
- Garage to apartment conversion: $60,000–$120,000+
These are ballpark figures based on local market trends. The garage conversion cost will also depend on permits, whether plumbing or HVAC needs to be installed, and structural work (like raising the floor or reinforcing the foundation).

Pros of Garage Conversions
Cost-Effective Expansion
Converting an existing structure is typically more affordable than building a new addition. You already have walls, a roof, and foundation—now it’s just about making the space livable.
Increased Home Value
A well-done garage conversion can boost your property value and appeal to buyers who want more living space or a rentable unit.
Customizable
No Major Footprint Changes
Because you’re working within the garage’s footprint, you usually don’t need zoning variances or additional lot coverage allowances in most Glenview neighborhoods.
Cons to Consider
Loss of Storage or Parking
If you rely on your garage for parking or storing tools, holiday decorations, or sports gear, you’ll need a plan for relocating those items.
Permit & Code Compliance
You’ll need permits, inspections, and must meet all local building codes—especially if you’re adding plumbing or HVAC. Hiring an experienced garage conversion contractor ensures nothing falls through the cracks.
Resale Preferences Vary
Some buyers see value in a finished garage. Others may prefer the ability to park inside. Make sure the layout works for your long-term needs.
What to Expect During the Process
Working with experienced custom home builders in Glenview, IL, your project will likely follow this general timeline:
- Initial Consultation – We’ll discuss your goals and assess the garage’s condition.
- Design & Planning – From floor plans to finishes, this is where we turn your ideas into blueprints.
- Permitting – We handle the paperwork so you don’t have to.
- Construction – Framing, insulation, electrical, plumbing, drywall, and finishing work.
- Final Inspection – Once the space is complete, it’s inspected for code compliance.
The whole process typically takes 2 to 4 months depending on the complexity of the project.
Choosing the Right Garage Conversion Contractor
Not all contractors are created equal. A garage conversion is part remodel, part new construction, and you want a team that understands both. Look for:
- Experience with garage conversions specifically
- Knowledge of local Glenview and Cook County building codes
- Transparent pricing and detailed timelines
- Great communication and client reviews
