An ADU Garage Conversion Guide

Thinking about transforming your garage into a living space? An ADU (Accessory Dwelling Unit) garage conversion could be just the project you need! Whether you’re looking to create a rental space, a guest house, or even a private office, a garage conversion could be the perfect solution for you.

As one of Colorado’s foremost tiny home builders in the Denver area, we’ll walk you through everything you need to know. Let’s dive in!

What Is a Garage Conversion?

A garage conversion is exactly what it sounds like—converting your existing garage into a fully functional living area. By turning that unused space into an ADU, you get an additional living area without expanding the footprint of your property. This can be ideal in areas where space is tight or where zoning laws limit new constructions.

ADUs are functionally similar to tiny homes, with slightly different legal requirements surrounding them.

Benefits of Converting Your Garage Into an ADU

Why should you consider a garage conversion? For starters, it maximizes the potential of your property. Not only can you create additional living space, but it could also boost your home’s value. You could rent out the ADU for extra income or use it as a guest suite for family and friends. It’s a win-win!

ADU Garage Conversion FAQs

You likely have a few questions, and we’ve got answers! Let’s break down some common concerns people have about ADU garage conversions.

How much does an ADU garage conversion cost?

Costs can vary, but generally, you can expect to spend at least $20,000 to $50,000 for a garage conversion, according to Angi. Prices will vary depending on the complexity and finishes. This investment can be recouped over time, especially if you use the space as a rental unit. We outline more factors that can affect your ADU’s price in our guide to ADU costs.

How long does a garage conversion take?

The timeline for a garage conversion is typically around 3 to 6 months, depending on factors like permitting, design, and construction. If you have an especially elaborate design or unexpected delays, the timelines can always vary, just like any other type of construction. It’s important to work with professionals to keep things on track, and stay patient!

What if I want my ADU and my garage?

Don’t be afraid to get creative! There are partial conversions, which can turn part of your garage into an ADU while the rest of the garage remains functional. Our customizable tiny home model, the William, is an ADU that rests on top of a garage.  It’s all about smart design!

How ADU Garage Conversions Work

So how exactly does an ADU garage conversion go from concept to reality? Let’s walk through the key steps.

Structural Evaluation

First, a structural evaluation ensures your garage is sturdy enough to support a living space. If it’s not, modifications might be needed to reinforce the structure. This step can also identify any underlying issues that may delay construction.

Zoning & Permitting

Next, you’ll need to navigate local zoning laws and secure the proper permits. This step is crucial to ensure that your ADU is legal and up to code. A professional tiny home builder can help you navigate the challenges of local permitting and codes.

ADU Design & Layout

Here’s where things get exciting! Work with an architect or designer to create a layout that makes the best use of the available space, whether it’s a studio, one-bedroom, or something else entirely.

Building Codes & Safety Standards

Your ADU must meet specific building codes and safety standards. This includes proper ventilation, plumbing, electrical, and fire safety features to keep your space safe and livable.

Demolition & Construction

Once the planning is complete, it’s time for demolition (if needed) and construction. This is where your garage begins to take on its new form as an ADU!

Use Cases for Garages Turned Into ADUs

Garage conversions can unlock all kinds of possibilities. Let’s explore some real-world examples of how homeowners are putting these spaces to use:

1. Rental Income to Offset Mortgage Payments

One of the most popular reasons for converting a garage into an ADU is to generate rental income. By turning the garage into a self-contained living unit, homeowners can rent out the space to long-term tenants or even use it as a short-term rental on Airbnb. This additional income can help cover mortgage payments, property taxes, or even fund home improvements. In areas with high demand for rental housing, an ADU can bring in significant income, making it a smart financial investment.

2. Home Office or Creative Studio

As remote work continues to grow, more people are looking for a dedicated space to work from home. Converting a garage into an ADU offers an ideal solution for a quiet home office or creative studio. By creating a separate space away from the main living areas, homeowners can maintain a better work-life balance, reduce distractions, and increase productivity. Whether it’s a tech startup workspace or an art studio, a garage ADU can provide the room needed for professional or personal projects.

3. Guest Suite for Family and Friends

For homeowners who frequently host out-of-town guests, turning a garage into a guest suite is a practical option. Rather than using valuable space in the main home or relying on hotels, an ADU provides a private, comfortable space for visitors. With a separate entrance, a full bathroom, and a small kitchenette, guests can enjoy their own space while staying close to family or friends. It’s a convenient way to accommodate guests without disrupting daily routines.

4. Aging in Place or Multigenerational Living

Garage ADUs can also serve as living spaces for elderly parents or adult children. For families that want to support aging parents while allowing them to maintain their independence, converting a garage into a small apartment can be a perfect solution. Parents can live close by but have their own space, with features like easy-to-access showers, wide doorways, and grab bars to ensure safety. Similarly, young adults looking for affordable housing options can benefit from living in an ADU while staying close to family.

5. Flex Space for Hobbyists or Fitness Enthusiasts

A garage ADU doesn’t have to be just a living space. It can also be transformed into a multifunctional area for hobbies, fitness, or even a home gym. For example, fitness enthusiasts can convert their garage into a personal gym, complete with exercise equipment, storage for gear, and a small bathroom or sauna. Hobbyists, such as musicians or woodworkers, can use the ADU as a dedicated space to pursue their passions without cluttering up the main home.
