Is Adding a Garage to Your Existing House Worth It?

Adding a garage to your existing house can be a game-changer. Let’s break down why this addition is often worth the investment.

Boosting Home Value

A new garage can significantly increase your home’s value. According to Forbes, a well-designed garage can improve the aesthetic appeal of your home and attract potential buyers. Homes with garages often sell faster and at higher prices compared to those without.

Enhancing Appeal

A garage isn’t just a place to park your car. It can be a workshop, a hobby space, or even additional storage. This multifunctionality makes your home more appealing. Imagine having a dedicated space for your DIY projects or a safe spot for your golf cart. The possibilities are endless.

Increasing Functionality

Garages provide extra space that can be used in various ways. Whether you need a laundry room, a utility room, or just more storage, a garage can accommodate. For example, one Reddit user shared that they recently added a garage to their home because it was the only feature missing. This addition not only met their needs but also allowed for future expansion, like adding a second story.

Improving Resale Value

Investing in a garage can pay off when it’s time to sell your home. A garage addition can make your property more attractive to buyers, who often look for homes with ample storage and parking. Plus, selling and buying another house incurs significant costs—up to 10% in equity due to commissions and fees. By adding a garage, you avoid these costs and improve your current home’s resale value.

Real-Life Example

Consider the story of a homeowner who added a garage because their house lacked this feature. The project cost around $40,000, which is plausible for such an addition. Despite the initial expense, they found it more cost-effective than moving to a new house. Plus, they got exactly what they wanted without the hassle of buying, selling, and moving.

Final Thoughts

Adding a garage to your existing house is a smart investment. It boosts your home’s value, improves its appeal, increases functionality, and improves resale value. If you’re happy with your current location and your home meets your needs, a garage addition can be the perfect solution.

Types of Garage Additions

When considering adding a garage to your existing house, it’s important to know the different types of garage additions available. Each type has its own benefits and challenges, so let’s break them down.

Attached Garage

An attached garage is built as an extension of your home. It shares one or more walls with the main structure. This type of garage is convenient because it provides easy access to your home, especially during bad weather. You can also use existing utilities, like heating and electricity, which can save money.

Pros:
– Convenient access to the house
– Lower construction costs (only three walls needed)
– Easier to use existing utilities

Cons:
– Must match existing home design
– Potential for fumes and noise to enter the house

Detached Garage

A detached garage stands alone, separate from the main house. This type of garage can be placed anywhere on your property, giving you more flexibility in design and location. It’s a great option if you want to keep car fumes and noise away from your living space.

Pros:
– Flexibility in location
– Keeps fumes and noise away from the house
– Easier to design without matching the house

Cons:
– More expensive (four walls and separate utilities)
– Less convenient access, especially in bad weather

Carport

A carport is a semi-covered structure, usually open on at least one side. It’s a budget-friendly option that offers basic protection from the elements. While it doesn’t provide the same level of security as a garage, it’s easier and cheaper to build.

Pros:
– Lower cost
– Quick to build
– Provides basic protection from weather

Cons:
– Less security
– Not suitable for storage or additional uses

Tandem Garage

A tandem garage is designed to house two or more vehicles in a single-file line. This design is ideal for narrow lots where a traditional side-by-side garage wouldn’t fit. It’s also a good option if you need extra storage space.

Pros:
– Space-efficient
– Good for narrow lots
– Can provide extra storage

Cons:
– Inconvenient for accessing the back vehicle
– Limited to narrow lots

Choosing the right type of garage addition depends on your needs, budget, and the layout of your property. Whether you opt for an attached or detached garage, a carport, or a tandem garage, each option has its own set of benefits and challenges.

Next, we’ll dive into the planning phase, covering zoning codes, HOA rules, and other crucial considerations for your garage addition.

Planning Your Garage Addition

Planning your garage addition involves several important steps. Here’s what you need to know:

Zoning Codes

First, check your local zoning codes. These rules dictate how close you can build to the edges of your property. Visit your local planning department to get the specifics. They can tell you about any special restrictions, like deeper setbacks for garage doors.

HOA Rules

If you live in a neighborhood with a Homeowners Association (HOA), you’ll need to review their rules too. HOAs often have guidelines on the appearance, size, and placement of new structures. Make sure your plans comply to avoid any issues later.

Setback Requirements

Setback requirements are the minimum distances your garage must be from property lines. These vary depending on your location and can affect where you place your garage. For example, some communities require garages with doors to have deeper setbacks.

Driveway Requirements

Adding a garage means you’ll likely need a driveway. In newer areas, single-car driveways should be at least 10 feet wide, while two-car driveways should be 20 feet wide. If you plan to park in front of your garage, ensure there’s at least 20 feet between the sidewalk and the garage door.

Impervious Area

Impervious surfaces include roofs and pavement. Many local rules limit the total amount or percentage of your lot that you can cover with these surfaces. Check with your local planning department to ensure your garage addition won’t exceed these limits.

Architectural Style

Finally, consider the architectural style of your garage. It should complement your house, not overshadow it. For an attached garage, try to match the roofline and materials. If you’re building a detached garage, ensure it looks like an accessory to your house. Adding windows and house-like details can help blend the garage with your home’s style.

By keeping these factors in mind, you can plan a garage addition that meets all regulations and improves your property.

Next, we’ll discuss the steps involved in adding a garage to your existing house, from design to finishing touches.

Steps to Add a Garage to Your Existing House

Adding a garage to your existing house involves several key steps. Each step is crucial to ensure your new garage is functional, aesthetically pleasing, and compliant with local regulations. Here’s a breakdown of the process:

1. Design

Start with a clear design plan. Work with an architect or designer to create a blueprint that matches your vision. Consider the size, layout, door placements, and any additional features like windows or storage areas. Ensure the design complements your home’s existing architecture.

2. Permits

Before any construction begins, you need to obtain the necessary permits. Check with your local zoning office for requirements. Permits ensure your project complies with building codes and safety regulations. This step could involve submitting detailed plans and undergoing inspections.

3. Foundation

The foundation is the base of your garage. It needs to be strong and level. Typically, a concrete slab is poured to create a solid foundation. This step might involve excavation and site preparation to ensure the ground is stable.

4. Framing

Once the foundation is set, the framing begins. This involves constructing the skeleton of the garage using wood or metal studs. The framing defines the shape and structure of your garage, including walls, roof, and openings for doors and windows.

5. Roofing

Next, the roof is added. The type of roofing should match or complement your house. Options include asphalt shingles, metal roofing, or tiles. Proper roofing ensures your garage is weatherproof and durable.

6. Siding

The exterior siding is installed to protect your garage from the elements and match your home’s exterior. Options include vinyl, wood, or cement-based siding. Cement-based siding, while more expensive, is excellent for avoiding termites and rot.

7. Electrical

Running electricity to your new garage is essential for lighting, power tools, or charging stations. If you need 220-amp outlets, an electrician will likely need to install a new subpanel. This step may involve digging a trench for underground wiring.

8. Plumbing

If your garage will include a utility room or bathroom, plumbing must be installed. This involves running water lines and drainage systems, which should be handled by a professional plumber to ensure compliance with codes.

9. Insulation

Insulating your garage is crucial, especially if you plan to use it as a workshop or living space. Insulation helps regulate temperature and improve energy efficiency. Fire codes require insulation between the garage and the house, but insulating the entire garage is a good idea.

10. Flooring

Finally, choose your garage flooring. Options include bare concrete, epoxy paint, concrete stain, or coverings like snap-together tiles or floor mats. If you’re adding a workshop or gym, consider durable and easy-to-clean flooring options.

By following these steps, you can ensure that your garage addition is well-planned, functional, and adds value to your home. Next, we’ll dig into the costs involved in adding a garage to your existing house.

Cost of Adding a Garage to Your Existing House

When considering adding a garage to your existing house, understand the costs involved. These can vary widely based on several factors. Let’s break it down.

Average Costs

The cost to build a garage can range significantly. On average, a basic one-car garage can cost between $10,000 and $25,000. For a two-car garage, expect to pay between $20,000 and $45,000. These figures can increase if you add more features or opt for high-end materials.

Materials

The materials you choose will greatly affect the overall cost. Here’s a quick rundown of common materials and their impact on your budget:

• Concrete for the foundation: Typically costs around $75 to $100 per cubic yard.
• Framing lumber: Prices can vary, but expect around $2 to $5 per linear foot.
• Siding options: Vinyl siding is more affordable, while cement-based siding is expensive but durable.
• Roofing materials: Asphalt shingles are economical, while metal roofing can be pricier but lasts longer.

Labor

Labor costs can vary depending on your location and the complexity of the project. On average, labor can account for 40% to 60% of the total cost. Hiring experienced contractors ensures quality but will come at a higher price.

Regional Costs

Regional costs also play a role. For example, building in urban areas or regions with a high cost of living will be more expensive. Conversely, rural areas might offer lower labor and material costs. Always get multiple quotes from local contractors to understand the specifics for your area.

Add-Ons

Adding features will increase costs but can also add significant value. Consider these common add-ons:

• Insulation: Essential for climate control, especially if you plan to use the garage for more than just parking.
• Electrical work: Adding outlets, lighting, or a subpanel can increase functionality but will add to the cost.
• Plumbing: If you’re adding a utility room or a bathroom, plumbing work can be substantial.
• Flooring: Upgrading from bare concrete to epoxy or tiles will add to your budget.

Cost-Saving Tips

Here are some tips to help you save money without compromising on quality:

• Plan thoroughly: Clear planning can avoid costly changes later.
• DIY where possible: If you have the skills, consider handling tasks like painting or basic carpentry yourself.
• Get multiple quotes: Compare prices from different suppliers and contractors.
• Choose cost-effective materials: Opt for durable yet affordable materials.
• Consider prefabricated options: Prefab kits can be a cost-effective alternative to custom builds.
• Build in the off-season: Construction costs are lower during off-peak months.

By understanding these factors, you can better plan your budget and make informed decisions.

Next, we’ll explore the design considerations for your garage addition to ensure it meets your needs and improves your home’s value.

Design Considerations for Your Garage Addition

When adding a garage to your existing house, it’s important to consider several design elements to ensure the space is both functional and aesthetically pleasing. Let’s dive into the key factors you’ll need to think about:

Size

The size of your garage will depend on its intended use. For a single-car garage, aim for at least 14 feet by 20 feet. If you have two cars, a 20 feet by 24 feet space is the minimum, but adding an extra 6 to 8 feet in both directions will give you more room to move around.

Pro Tip: Always plan for a little more space than you think you’ll need. It’s easier to fill extra space than to deal with a cramped garage.

Layout

The layout should maximize functionality. Consider how you’ll use the space: Will it be just for parking, or will you need room for a workshop, storage, or a home gym?

Example: A homeowner in Palo Alto turned part of their garage into a small electronics workshop, inspired by the famous Hewlett-Packard garage.

Windows

Windows not only improve the garage’s appearance but also bring in natural light, making the space more pleasant to work in. Place windows strategically to avoid glare and maximize daylight.

Doors

Choose between one large door or two smaller ones. Two smaller doors often look better and make it easier to park cars without worrying about hitting the sides.

Security Tip: An attached garage offers better security. You can drive in and close the door without stepping outside.

Lighting

Good lighting is crucial. Overhead lights are a must, but also consider task lighting for work areas. LED lights are energy-efficient and provide bright, clear light.

Case Study: One of our clients added LED strip lights over their workbench, making it easier to see small details during woodworking projects.

Storage Solutions

Effective storage solutions can turn your garage from a cluttered mess into an organized haven. Shelving units, pegboards, and built-in cabinets can keep tools and other items neatly stored yet easily accessible.

Fun Fact: Decluttering your home and moving items to the garage can make your living space more pleasant and increase your home’s overall appeal.

Climate Control

If you plan to spend a lot of time in your garage, consider climate control options. Insulation is a must, and depending on your climate, you might need heating or air conditioning.

Budget Tip: A ceiling fan might be all you need to keep the garage cool in the summer.

By carefully considering these design elements, you can create a garage addition that not only meets your needs but also improves your home’s value and functionality.

Next, we’ll discuss the top features and options to consider when designing your garage addition.

Top Features and Options for Garage Additions

When adding a garage to your existing house, think about how you’ll use the space. Here are some top features and options to consider:

Workshop

A dedicated workshop can make your garage the ideal place for DIY projects.

Tips for Workshop Setup:

• Work Bench: A sturdy work bench is a must. It provides a reliable surface for your projects.
• Lighting: Install bright, focused lighting over the work bench. This makes it easier to see what you’re doing.
• Electrical Outlets: Place outlets near your work area. This will minimize the need for extension cords.

Example: John from Massachusetts added a workshop to his garage. He installed built-in cabinets and pegboards to keep his tools organized. Now, he can work on his woodworking projects without cluttering the house.

Hobby Space

Hobbies like building model trains or making stained glass lamps need space and can get messy.

Hobby Space Essentials:

• Dedicated Area: Set aside a specific area for your hobby. This keeps your supplies and projects organized.
• Storage: Use shelves and bins to store materials. This keeps everything you need within reach.
• Surface: A large table or workbench provides ample space to spread out your project.

Quote: “Having a dedicated space for my model trains has been a game-changer. I don’t have to pack everything up each time I stop working,” says Mike, a hobbyist from New Hampshire.

Laundry Room/Utility Room

Moving your laundry room to the garage can free up space inside your home.

Laundry Room Setup:

• Plumbing: Ensure your garage has the necessary plumbing for a washer and dryer.
• Ventilation: Proper ventilation is crucial to prevent moisture buildup.
• Storage: Install cabinets or shelves for detergent and other supplies.

Fact: Older homes often lack a laundry room, but adding one during a garage remodel is a practical solution.

Golf Cart Storage

If you live in a community where golf carts are common, having a dedicated storage space is beneficial.

Golf Cart Storage Tips:

• Charging Station: Install an electrical outlet for easy charging.
• Protection: Keep the cart out of the sun and rain to prolong its life.
• Space: Ensure there’s enough room to move around the cart comfortably.

Pro Tip: Adding a small ramp makes it easier to drive the cart in and out of the garage.

Entertainment Area

Transform part of your garage into a hangout spot.

Entertainment Area Ideas:

• Seating: Add comfortable seating like couches or recliners.
• Wi-Fi: Extend your home’s Wi-Fi to the garage for streaming movies or gaming.
• Bar: Install a small bar with a fridge for drinks and snacks.

Example: Sarah converted part of her garage into an open-air pub. She added a bar, some stools, and a dartboard. Now, it’s the perfect spot for weekend get-togethers.

She Shed

A “she shed” is a personal retreat space, often used for relaxation or creative activities.

She Shed Essentials:

• Comfort: Add cozy furniture and soft lighting.
• Decor: Personalize the space with your favorite colors and decorations.
• Functionality: Depending on your interests, you might add a small desk, art supplies, or a sewing machine.
