Cost to build a back house
The cost to build a back house will vary based on the size and amenities of the home. The average cost of building a back house is around $30 per square foot, or $60,000 for a 1,200-square-foot addition. This price is an estimate based on local labor rates in your area and includes materials and labor.
Adding a back house to your home can increase its value by as much as $20,000. It also makes it easier to sell later on down the road if you want to move into a larger home elsewhere or downsize into something smaller.
The first thing you need to decide when building a back house is where it will be located on your property. You should discuss potential locations with your contractor before making any decisions so he can advise you on the best place for this addition.
It’s helpful if you have an idea of what features you want in your new space before construction begins. Some features that homeowners like include:
A mudroom area near the garage door where people can take off their shoes and store coats and jackets
A laundry room with washer and dryer included for easy cleaning of clothes
An extra bedroom or guest room for visitors who stay overnight.
Cost to build a back house
The cost to build a guest house can vary greatly depending on its size, location and the type of materials used. The average cost for building a guest house is $8,000-$30,000.
On average, homeowners spend $8,000-$15,000 to construct an attached guest house and $10,000-$40,000 for a detached one. A detached guest house may cost more because it requires more materials and labor; however, it allows you much more flexibility in design.
A guest house built with prefabricated materials costs around $35 per square foot compared to approximately $25 per square foot for a custom-built home.
Here’s the average cost to build a backyard guest house in 2019.
Attached vs. Detached Guest House
The first thing to consider when building a guest house is whether to attach it to your main home or to build it detached from your home. Attaching the guest house directly to your main residence will allow you to access it from inside of your home, but it can be more difficult to rent out, as most guests prefer having their own private space. If you choose this option, make sure that there is easy access between the two structures so that guests can easily come and go as they please.
Guest House Costs
The average cost for construction of a guest house is estimated at $20 per square foot ($200 per square meter), or $20,000 for a 1,000-square-foot (92-square-meter) structure. This includes labor costs and all materials needed for construction, including framing materials and insulation (for those who want extra insulation).
A prefabricated backyard guest house with bathroom can cost anywhere between $40,000-$100,000 depending on size, quality and extras like porches or decks
