What Does a Home Addition Cost in Grand Rapids, MI? | Ridgewood Home Construction

Written by Teresa Rose | Jul. 02, 2025

Are you thinking about expanding your home? No matter if you're adding a sunroom, a primary suite, or simply need more square footage, home additions add to your comfort and lifestyle. If your home is starting to feel cramped or no longer fits how your family lives, you're not alone. Many West Michigan homeowners eventually face the question: Should we move or add on? Let's look at what a home addition really costs in Grand Rapids. 

How Much Does It Cost to Add to Your House in Grand Rapids?

Let's discuss how much it really costs to add to your home. This list is not exhaustive, but it can give you an idea of what to expect when building an addition in West Michigan. The numbers below are averages, but we're happy to provide more details if you want a more in-depth explanation with our cost guide

Sunroom Additions

Sunrooms are a popular choice in Michigan because we all want more light, especially in the colder months. A three-season sunroom with basic windows and minimal insulation will be more affordable than a four-season version that’s fully insulated, heated, and cooled. Interior finishes, flooring, ceiling treatments, and trim will also influence the final price.

Sunroom additions in Grand Rapids typically start around $70,000. These four-season spaces include insulation, heating, drywall, paint, luxury vinyl flooring, cathedral ceilings, and large windows or sliding glass doors. They’re a popular choice for enjoying natural light all year long.

Primary Suite Additions

Creating a spacious bedroom with an attached bathroom and walk-in closet is a game-changer for comfort. Depending on how elaborate your bath is (think tile showers, freestanding tubs, heated floors) and how much storage you add to your closet, costs can range significantly.

Primary (master) suite additions generally begin at $150,000. A typical primary suite includes a spacious bedroom, a walk-in closet, and a bathroom with upgraded finishes, such as a tile shower with a glass door, a premium vanity with quartz countertops, and luxury flooring. This kind of addition is often chosen in homes to create a private retreat or accommodate changing family needs. Sometimes our clients come to us thinking they want a master bump-out, but an addition will suit their needs better. This is why it's important to work with a remodeler who truly knows the business and can help you make the right decision for your home.

Multi-Room Additions

Do you need a combination of spaces? Larger footprints and multiple utility hookups will increase costs, especially if excavation and foundation work are needed.

Multiple room additions typically start around $175,000, depending on the size and features. These highly customizable additions can include larger kitchens, mudrooms, guest suites, or expanded living areas. This type of project is ideal for families looking to grow in place while adding long-term value to their homes.

Factors Impacting Cost 

What factors impact the cost of a home addition in West Michigan? There’s no universal price tag for a home addition or living space remodel. Every project is different because every family and every home is different. That said, the cost of a home addition in Grand Rapids is shaped by three core factors:

1. Size and Layout

When it comes to additions, size is typically the biggest factor influencing cost. This is because an addition requires many structural components, including excavation, foundation work, framing, siding, roofing, electrical and HVAC systems, drywall, trim, flooring, and more. All of these elements scale up as the footprint grows.

A single-room bump-out will fall in a different range than a multi-room expansion with a full basement. Precise costs are difficult to nail down until you have plans in place. The beauty of remodeling is the customization, so don't hesitate to ask about something different. 

2. Finish Levels and Materials

Choosing luxury vinyl versus heated tile floors, stock cabinetry over custom millwork, or standard plumbing fixtures versus something more can significantly affect the cost. The best part about these variables is that you get to choose what you put in your home. You're investing in something that will impact your lifestyle for years.

3. Utility Requirements

If your addition includes plumbing, electrical, or HVAC changes, as is common with bathrooms, kitchens, and primary suites, costs will increase to accommodate those systems. This doesn't come as a surprise and will be factored into your initial quote. 

At Ridgewood Home Construction, we've seen a wide range of addition projects. Some homeowners prefer streamlined, efficient designs with standard finishes. Others have saved for decades to invest in high-end everything. Both are valid choices, as is everything in between. The “right” investment is the one that supports your lifestyle and budget.

Is a Home Addition Worth the Investment?

The short answer is absolutely, yes. It helps update your home, makes it more comfortable, and makes your living space feel like yours. Don't add on to your home just for resale purposes. Instead, focus on how the space will serve you in the future. And that’s a smart way to remodel. After all, you're the one living in the house every day!

Ask yourself:

  • Do you need another bathroom to reduce the morning rush?
  • Are you tired of making your home office double as the guest room?
  • Could a new primary suite finally give you the comfort and privacy you crave?
  • Would a sunroom add joy to your mornings or relaxation to your evenings?

These aren’t just home upgrades; they’re quality-of-life upgrades. Choose a home addition to improve your lifestyle and make your days more comfortable. Maybe it's a mudroom addition, a master suite addition, or even a bonus room. When you decide that it's time to add to your home, our process walks you through every step. 

Add to your home and lifestyle

It’s easy to get caught up in what might be good for resale. But unless you’re planning to move soon, your addition should be designed around your routines, your taste, and your comfort.

Love bold tile? Go for it. Want that extra-deep soaking tub? Install it. Remodeling should enhance how you use your home, not just how it looks on a listing sheet. At Ridgewood Home Construction, we believe in creating spaces built around real life. Spaces that work hard, look great, and feel good to live in.
