Cost of Building an Addition to House (Estimates and Pricing Factors)

When it comes time to build an addition to your home, you can expect to pay quite a bit of money to do so. Whether you’re looking to add additional storage, a guest house, or your family has simply grown and you just need more room, the total cost for your home renovation and room additions greatly depend on a number of factors and the circumstance of the project. An experienced contractor in the Phoenix, Arcadia, and Scottsdale contractor can help you to make all of the best decisions for your home and put together a good estimated cost of what you’re looking at.

Once you have a better idea of what all of the different pricing factors are, you can decide whether or not the addition or the extent of the addition that you’re planning is actually within your budget. It’s difficult to decide on renovating your current home, or simply purchasing and moving into a new one. If completed properly, choosing a renovation can provide a great return on investment.

If you’re considering an addition to your home, let’s take a look at all of the cost factors:

Type of addition

Are you looking at adding a second floor or a ground level addition? Maybe you’re thinking a detached addition would work best to have a casita or guest home. Each option has different associated costs.

Adding a room: When adding a room to a home, this could be a new bedroom, an office, or any other type of space that you need. You will either need to build out on the ground floor or build a second floor. Depending on the scope of the project and the route you choose to take when it comes to your layout and your lot, you’re looking at $80 to $200 per square foot. An experienced contractor can help you navigate the scope of the project. You will need to hire an architect for the design and layout, a structural engineer to be sure that all renovation plans are safe to do, and a contractor that takes on the grunt of the remodeling and renovation work.

Adding a room
When you add on to the ground level of your home, you’re not disrupting too much of the structure and other parts of the home during the renovation. You may need to add foundation and you may lose a good chunk of land that was otherwise your yard. It’s also extremely important to check in with the city to be sure the planned renovations aren’t against the code. Some city codes don’t allow you to build out to a certain point, and some won’t let you build up.

Adding a second story to your home adds more structural work and you need to be sure the foundation is solid to carry the weight. You will also need to consider the addition of a staircase which takes up additional room on your ground floor. Again, it’s important to check with the city to see if there’s a limit the height that you can build up.

Adding a detached addition: The most simple detached addition with simple rooms and no utilities run around $15,000. If you’re looking at making it a casita or guest house, you’re looking at a cost of around $25,000 total depending on the details you choose to add.

You will need to hire a contractor for the renovation work, and an electrician to help with the utility work. You will also need a plumber and a structural engineer.

Again, the cost will depend on your exact plans for this addition like the type of materials, the exterior design, the interior design, and more. You will need an architect to map out the full plan for you which can run close to $5,000 for this type of project.

Adding a sunroom: This is going to be the best option when it comes to cost-effectiveness and budget-friendly choices. The cost for a sunroom runs around $17,000 for a standard, average plan. If you’re looking at a much larger plan and slab foundation, this project can run on the upwards of $70,000. You will also need to consider the location of the sunroom and what the utilities will look like.

Adding a sunroom
You’ll want to hire an electrician, a carpenter, and also a painter. They all charge on the hour and the costs run anywhere from $30 to $100 per.

If you’re planning to use the sunroom during all seasons, you’ll need to add heating and cooling utilities in which you’re looking are around $300 to $400 per square foot for the total cost of your addition You can opt out of these utilities if you use the sunroom for only part of the year. Here in Arizona, it’s probably a good idea to do that considering how hot it is in the summer.

Be sure to hire an experienced contractor like Pankow Construction to be sure that you’re getting the best project scope for your property and the location your property is in.

Does the addition increase home value?

Making an addition to your home will not automatically increase the value of your home drastically, but it has the potential based on the scope of the full project and how the renovation goes. Home additions tend to be a much larger investment than a standard remodel so sometimes, homeowners are disappointed when the return doesn’t equate to what they thought. If the addition adds a good amount of square footage, it could certainly add great value to your home.

Contracting the best in the business when it comes to contractors, architects, and other professionals are imperative to a job well done. The investment may be greater on the front end, but in the long run, the end-product will be that much more amazing. If you’re concerned about added value to your home, putting together a solid plan with a reputable team will steer you in the right direction.

Are there hidden costs?

As with any home renovation project, there are certain costs that pop up out of nowhere that most homeowners don’t expect. Once the contractor and other home remodeling professionals begin work, they could come across an issue or something that’s not up to code and needs to be addressed and fixed. Here are a few of the hidden costs of home additions:

The cost of permits: You will need a permit if you’re making an addition to your home. The permit costs depend on the estimated cost of the renovation project as a whole. You may also need permits for electrical and plumbing work. Don’t forget the actual application fee as well. Often times, permits can end up costing you a few hundred before the project has even begun.

Remodeling contract: Be sure that the contract is fixed-cost when you go to sign it. This will prevent you from spending additional money if unforeseen circumstances come up during the addition project. This will make it so that you’re only responsible for the cost as outlined in the contract and you won’t end up paying for things like additional material costs or mold.

Landscaping: If you build onto the ground level square footage of your home, you’ll also need to fix the landscaping that’s been altered. Depending on what you want to do with it, this could be a smaller or a larger cost, but it does add to the total project.

Home insurance and property taxes: If you increase the size of your home, your taxes and home insurance will increase as well. You will need to consider that you’re monthly and annual costs for your home will be higher after you make an addition to your home.

Additional finance charges: If you’re using a remodeling contract to pay for the home addition, you’ll need to consider all of the associated costs that go with that. This includes interest, inspections, appraisals, processing fees, and more.

Ways to lower your costs

If you plan accordingly, you can indeed lower your overall costs and meet a lower budget when it comes to an addition to your home. Consider doing some of the work yourself, changing your original thoughts for the renovation, or considering alternative financing options that don’t include a loan. Here’s a list of options that keep your costs lower when it comes to these types of renovations:

  • You can add a detached option as opposed to an attached build on or build up
  • Work more closely with your contractor
  • Get a no-interest loan from a family member
  • Purchase materials on your own
  • Apply for the permits on your own
  • Refinish your basement instead of getting an addition
  • Add cabinets if you’re just in need of storage

All of these are great options if renovating your home doesn’t make sense for your current budget and your reasoning for doing the addition in the first place. If you’re just looking for more storage space or you have a greatly sized basement, you can use these to your advantage and save tons of money by simply utilizing those options.

Using these professionals will help you to achieve the flow that you’re looking for so that it looks like it was meant to be there. Everything needs to tie in nicely and while the upfront costs may be a bit higher, it’s worth it to have a professional team working with you in the long run. Because a home addition investment is so high, it’s key to protect it by making the best possible decisions you can when it comes to the planning and renovation of your home.

Choosing a contractor

When it comes time to pick a contractor for your project, it’s important to go with a highly reputable option with great experience. You will want to be sure that they’re licensed and insured, and you’ll want to look into their experience. Talk through the project with the contractor and be sure to ask all of the questions that you have up front. Then you can decide if they make sense for your budget, your timeline, and your end goal.
