Garage conversions are a rising trend in home improvement, and for good reason! They offer homeowners the opportunity to maximize their living space and increase property value without the need for a full-scale home addition. But before you start, understanding the costs involved is crucial for planning a successful project. This guide will provide a comprehensive look at the factors influencing garage conversion costs, detailed cost breakdowns for various types of conversions, and practical tips for saving money without sacrificing quality.

Garage Conversion: What's in it for You?

Converting a garage into a functional living space has numerous benefits:

  1. Increased Living Space: Whether you need an extra bedroom, a home office, or a personal gym, converting your garage can provide the additional space you need.
  2. Property Value Boost: A well-executed garage conversion can significantly increase your home's market value.
  3. Cost-Effective Expansion: Compared to building a new addition, converting an existing garage is often more affordable and quicker to complete.
  4. Versatility: The new space can be customized to meet your specific needs, from a cozy in-law suite to a state-of-the-art entertainment room.

Factors Influencing Garage Conversion Costs

Several factors can influence the overall cost of your garage conversion project:

  1. Size and Condition of the Garage: Larger garages and those in poor condition will require more materials and labor, increasing costs.
  2. Desired Use of the New Space: The type of room you want to create—be it a bedroom, office, or kitchen—will dictate the specific requirements and associated costs.
  3. Material and Labor Costs: The quality of materials and the rates charged by contractors can vary, impacting your budget.
  4. Location: Costs can differ based on your geographic location and local building regulations.
  5. Utility Connections: Connecting plumbing and electrical lines can add to the expense, especially for detached garages.

Detailed Breakdown of Costs

Garage Conversion ADU

Cost to Convert Garage to a Bedroom

Converting a garage into a bedroom typically costs between $5,000 and $17,000. Smaller bedrooms with basic elements like a window, insulation, drywall, flooring, outlets and switches, HVAC, and a closet fall at the lower end of the price range. Larger bed/bath suites cost more due to the additional space, fixtures, and plumbing.

Cost to Convert Garage into a Studio Apartment or In-Law Suite

The cost to convert a garage into an apartment or in-law suite ranges from $20,000 to $100,000+, depending on the size and features. Full conversions involve framing, drywall, building a bathroom and kitchen, adding heating and cooling, and finishing the interior. New doors and windows may also be required for code compliance.

Cost to Convert Garage to a Kitchen

Converting a garage to a kitchen costs between $6,000 and $54,000+. A basic kitchen requires plumbing, electrical, flooring, insulation, drywall, and ventilation. Cabinets, storage shelves, countertops, and appliances also add to the cost. Most kitchens require one or more dedicated electrical circuits.

Cost to Turn Garage into Office Room

The average cost to turn a garage into an office is $5,000 to $10,000. Office essentials include insulation, drywall, a window, lighting and electrical outlets, HVAC, Wi-Fi or high-speed internet, and updated flooring. Most offices have one or more desks and cabinets or other storage furniture.

Cost to Turn Garage into a Living Room

Turning a garage into a living room costs $5,000 to $10,000 on average. This is similar to converting a garage into a simple bedroom or office, as they share the same basic requirements—a window, electrical wiring, insulation, drywall, heating/cooling, and updated flooring. Remember to budget for comfortable seating and entertainment options.

Cost to Convert Garage to a Utility Room

The average cost to convert a garage to a utility room is $3,000 to $6,000. Utility rooms typically house laundry appliances, storage options, and possibly a sink, requiring electrical wiring, plumbing, ventilation, insulation, and drywall at a minimum. Laundry areas require at least one dedicated 20-amp circuit for code compliance.

Cost to Enclose a Carport and Turn into a Room

The cost to turn a carport into a room ranges from $7,000 to $20,000+, depending on the new room type and requirements. Converting to an enclosed garage requires less labor and materials than converting to a living space. An attached carport typically costs less to enclose than a detached structure because it already has one or more walls in place and often shares the same foundation footings as the house.
