Detached Garage Electrical Wiring

Decisions about electrical and lighting will depend entirely on what the detached garage will be and the purposes that it will serve. If it is merely going to be a spot to protect your car from the elements, then necessary wiring for a single overhead light, or perhaps, electric to an automatic door opener will suffice. Otherwise, consulting an electrician about any of a myriad of possibilities is advisable. Electricians usually charge between $40 and $100. Surely, if living or workspace is considered, then lighting and electrical will be more extensive, especially when considering HVAC.

How Much A Garage Apartment Coststo Build

If youre interested in building a garage apartment to rent out, it helps to know how much this will cost.

Tim Shingly, chairman of the National Association of Home Builders Remodelers council tells The Wall Street Journal that his projects have ranged from $75,000 to $200,000, but it depends on the finishes.

Another site, this time Sapling, states that people in the U.S. spend roughly $26,000 to build a garage without an apartment.

When the apartment is included in the deal, the costs rise to approximately $70 per square foot for a home thats separate from the main dwelling. So, youre looking at between $18,000 and $47,000 for a garage home.

This cost would obviously include provision for things like electrical wiring, plumbing, and insulation. In fact, insulation is a common problem with garage apartments.

Since a garage is obviously meant for cars, turning one into an apartment means that there wont be enough insulation for people to live in the space comfortably.

Therefore, the addition of insulation in the walls, ceilings, and floors will have to be considered during renovation.

What Are The Benefits Of Converting Your Garage Space

Many families need more living space or storage and parking. With a little planning and the right vision, a garage can find many new uses:

1. An added bedroom. Families grow in all sorts of ways, from new children to older relatives needing care. Extra sleeping space is also useful for guests.

2. More living space. Rather than building a new room, this space can become a family room, dining area or game room.

3. A studio or office. More and more companies let their employees work remotely. This requires office space at home.

4. An apartment. Added income can be important for a home. Changing it into an apartment could provide some help in paying the mortgage.

Why You Need A Garage

The garage is an integral part of American home design. It’s a great space for parking your car in order to preserve its lifespan and even future resale value according to Your Car Cave. A garaged vehicle is less prone to sun damage or wear as a result of extreme temperatures.

In the United Kingdom, overnight parking conditions are a key policy writing question many insurers will offer drivers a discount if their car sits in a dedicated indoor space rather than on the street . This is because a car left out in the open is at greater risk of scrapes, bumps, and theft than one being stored indoors.

In addition to the car-related rationale, adding a garage serves homeowners in a variety of additional functions.

Storage space is critical in any home environment

One of the most overlooked components of any home is the storage that it offers homeowners simply don’t realize the value of storage until it’s too late. Building a garage can help you finally move out of the third-party storage unit you’ve been renting since the last move .

Some homeowners have developed a significant collection of tools and DIY equipment, while others may be struggling to keep boxes upon boxes of photos and mementos organized and efficiently packed away. Regardless of your personal circumstances, it is always nice to have additional room to store your things.

How Much Does A Detached Garage Add To Property Value By Location

Much like an attached garage, a detached garage contributes to your homes value since it adds usable square footage.

I also give some value for an unfinished, accessible second floor, she adds.

A functionally adequate garage in a typical market might add $5,000 to $25,000 worth of value, Mike Ford, a Southern California-based general certified real estate appraiser since 1986. In high-end markets, the value might be higher.

For example, if a homeowner in Austin spends an average of $45,419, they have the potential to add $29k to the value of their home.

Foundation Costs For A Detached Garage

As a wise man once said, Your garage is only as good as whats under it! It would be a shame to invest in a beautiful garage, only to have it begin falling apart in a few years because no thought was put into ground preparation. Key considerations for foundation selection include garage size/height and how prone your area is to frost.


The most cost-effective and most basic shed foundation is a gravel pad surrounded by a perimeter of treated wood. This is best for a smaller detached garage, especially pre-assembled or modular styles.
