Planning to Build an Addition to Your Home? Here’s What You Need to Know

building an addition

Building an addition is not a project for the faint-hearted, as it requires a large investment. Before embarking on this journey, it is important to have a firm idea of your budget. This will help you determine what your aspirations are, and you can then discuss various options within your limits. Usually, a budget is based on the price per square foot, which should give you a good idea of how much the project will cost.


There are several factors that determine the cost of building an addition. The materials used and the grade of the materials will affect the overall cost. For instance, if you need a new bathroom, you might consider purchasing stock vanity cabinets, rather than custom-made ones. Similarly, if your lot is sloped, you may need to have additional grading and foundation planning done. Finally, running plumbing and electrical lines will add to the total costs, and higher ceilings, bay windows and built-ins will add to the overall cost.

Before hiring a general contractor, you must have a clear understanding of your needs and the budget. The contract should outline all costs and specifications line-by-line, and should be agreed upon in writing by the contractor and homeowner. You will likely need to pay a down payment and make several payments along the way. This will be specified in the contract, along with payment deadlines. You should make sure that the general contractor you choose has adequate insurance and workers’ compensation insurance.


When planning an addition to your home, it is important to obtain all the necessary permits. Failure to obtain permits can cost you a lot of money, and your city will fine you for every day you are out of compliance. You could be held personally liable for these fines, which can run into the thousands of dollars. Fortunately, there are many benefits to getting permits before you begin any work. Aside from ensuring the quality of work, permits can also help you sell your home later.

Before you can begin building, you must obtain the proper permits. While it is not always necessary to obtain permits, a room addition, conversion of a garage, or sunroom will require the approval of your city. Some communities even offer online resources to help you learn more about permits. If you’re still unsure, you can call the permit office and speak with a building inspector directly. Many permit offices allow you to do this anonymously. However, it’s important to remember that online guidance doesn’t cover every aspect of the process.

Design options

When you’re planning to build an addition to your home, you’ll need to consider your design options first. Before you hire a contractor to start work, consider what you want from the new addition. Consider first and second options and rank them in order of importance. If you’re only adding a small room to increase the size of your home, design your new space around existing features. This way, you can ensure your new addition matches existing design.

Before choosing a design for your new addition, think about how the new space will affect your family. Keep in mind that you’ll have less space for a while. Plus, your water and energy bills may increase during construction. If you’re adding a second story, you’ll need a variance from the local building department to allow the addition. And don’t forget to consider the location of the addition. If you’re planning to build a new addition on your home, it’s important to check zoning regulations for that area.

Construction timeline

The construction timeline for building an addition depends on a variety of factors. Starting with architectural plans, preparing blueprints and obtaining permits, this process can take anywhere from weeks to months. Excavation for a new addition can take three to four days, while building a foundation can take a few days. Framing a typical thousand-square-foot addition can take 230 to 270 man-hours. Finishing the interior can run simultaneously with exterior work.

Planning the construction timeline is crucial to the success of your project. While it may be tempting to push your project to the last possible minute, a quality home addition is not going to happen overnight. In order to make sure your project is completed on time, you should work with a high-quality construction company that has a proven track record for meeting deadlines. These contractors are renowned for adding extra costs and stretching out schedules.

Resale value

If you’re thinking of adding on to your home, one of the biggest concerns you may have is the resale value. Adding on an addition to your house is not just about adding more square footage, however. It can also have an impact on your home’s curb appeal. An addition with an ugly roof and exterior design can lower its resale value. Therefore, it is essential to plan your new room addition so that it flows well with the rest of your home.

Although adding a room to your home may not increase the resale value of your home, it will add to the overall value. In established communities, realtors will base their selling prices on “average” sq. ft. In addition, they will include the land value in their calculations. Thus, adding a hundred square feet to your home’s square footage can add up to 5% to your resale value. It can be beneficial to add a large dream kitchen or an on-suite bathroom, but the opposite is true.
