Factors affecting home addition costs

The total cost of your home addition project will be influenced by a number of factors you should take into account, including:

• The complexity of the architectural design plans
• Whether you’re adding onto the ground floor or a higher story
• Labor fees in your area

Cost saving tips for home additions

If you’re concerned about staying within budget, don’t worry—there are plenty of actions you can take up front to help you save on the cost of your home addition. 

Plan thoughtfully

Upfront planning is key to renovation projects. You and a designer or architect should make a detailed plan from the start. That will help you avoid costly changes and delays once construction gets underway. 

Set a realistic budget

Any successful home renovation is covered by realistic budget planning. Be honest with yourself about your finances and access to funds: How much can you afford to spend on the addition? Your budget should account for labor, design, materials, permits, and any unforeseen expenses.

Simplify your design

It’s fun to daydream about intricate designs, but the reality is: The more complex your design, the more expensive the home addition costs will be. To work within a smaller budget, finalize a simpler design for your home addition. You can deprioritize luxury features while still meeting the needs of your new space. 

Time your project during off-peak seasons

Your project costs are affected by not only where and what you’re renovating, but when you’re kicking off the project. Plan your project during off-peak seasons when contractors are more available and labor costs are lower. Typically, this is during the winter months.
