3. Home Addition Cost Factors
Some home addition cost factors stand out more than others. The size, type, and design of an addition make a noticeable impact, and many local and labor-related prices tip the scales as well. Below are some factors that impact home additions.
Project Size and Scope
Home addition square footage cost will vary depending on the home, material, and type of room you are envisioning. The average price per square foot comes out to $140 but generally ranges.
Hiring a general contractor is the most important step in determining your home addition cost. More complex builds will need a structural engineer and an architect. Below are some of the following factors:
- General contractor and architect fees
- Local permits
- Framing
- Foundation
- Roofing
- Siding
- Insulation
- Electrical
- Plumbing
Location of Addition
The location is where you are thinking about adding it. In the back of the house? On the second floor? Will I need wiring? Will you need to accommodate structures? These are important questions to ask yourself about the project to prepare.
Labor
About 50-60% of the cost of building a home addition goes toward labor. The majority of the work requires a licensed professional. Here are some standard rates for these.
| General Contractor | 10-20% of project |
| Architect | 5-10% of project |
| Plumber | $45-$200 an hour |
| Electrician | $50-$150 an hour |
| Carpenter | $75-$100 an hour |
Materials
Every design is different, so it is important to calculate your specialized cost before assuming your total home addition price.
- Foundation Cost: $4-$100 per square foot
- Framing Cost: $400-$1,500 per 1,000 feet
- Drywall Cost: $2.50 per square foot
- Insulation Cost: $1.50 to $5.00 per square foot
- Flooring Cost: $1 to $10 per square foot
Permits
It is important not to overlook the cost of building permits when adding a new structure to your home. More minor permits may cost around $200, but building a new structure can push a license up to $3,000.
Zoning Laws
You need to remember that your ideas for designing a home addition have to align with local zoning and building laws. Access to utilities, sewer drainage, and distance from your property line are a few things you need to consider.
4. Tips to Keep Cost Down
When you are adding to your home, it may become expensive, so there are some things that can help keep costs down. Here are some ways to do so:
- Set a realistic budget: Determine how much you can afford in addition, including the design and materials. Make sure to leave room for unexpected costs
- Plan thoughtfully: Spend the time on planning the design because making changes during construction may be costly
- Choose a simple design: Complex designs tend to be more expensive, so try to choose a more straightforward design that still meets your needs.
- Maximize existing space: Consider how you can use the existing space more efficiently before adding more square footage.
- Prioritize needs over wants: Focus on the essential features of your addition that add more value
- Time your project right: Plan your project during off-peak construction season to lower labor costs and have better availability.
5. ROI on a Home Addition
The return on investment (ROI) on a home addition can vary depending on a number of factors, such as the size of the addition, the materials you chose, the labor cost, and the complexity of the project. According to the National Association of Realtors, the ROI for adding a new bathroom is 63%, and adding a new primary bedroom suite is 56%.
The actual ROI you experience may be higher or lower depending on those factors. If you chose high-end finishes, you may be able to recoup more of the cost, but if you chose less expensive additions or cast, you may recoup less of the price.
It is important to understand that the ROI of a home addition is not guaranteed and that there are many things that go into it and affect the value of the home, including the condition of your home, the location of your home, as well as the current market conditions.
