How to Build an Addition
Draw up thorough designs for your home addition and work with a trusted contractor
Before you begin to plan your home addition, ask yourself how you want to use the space. Since building an addition is a similar process to building a new home, you want to make sure you have the purpose and the design decided upon before beginning construction. Consider all the different layouts you could implement and the materials and appliances you would need. This will give you a better sense of the costs involved with building an addition.
- Will you build a two-story or one-story addition?
- Where will you build: on the side, back or front of the house?
- What will you use the space for?
- Master bedroom suite
- Bonus room for the kids
- New nursery
- Kitchen and dining room expansion
- All-season sunroom with a hot tub and wood stove
- Which utilities will you need: plumbing, electricity, heating and cooling, cable or internet?
- Do you want the space to connect to the existing home through a doorway or an open room?
- Do you want doors leading from the addition to the outside?
You should obtain quotes from several contractors before choosing one to handle your construction. This will help you get the best deal and allow you to work with someone who understands your vision. Having a strong design plan will also give you a more accurate quote from the contractor, which in turn helps define how much financing you need for your home addition.
Research zoning regulations before building an addition
After you have drawn up building plans, check your local zoning restrictions to make sure you can build the home addition you've designed. Zoning laws tell you what you can build and where you can build it in. There may be restrictions on how close you can build to the property line, how large your addition can be and whether or not you can build a two-story addition. There may also be permits attached to these zoning laws that you'll need to obtain before you begin construction, so be sure both you and your contractor are aware of local restrictions.
You'll also want to know the locations of your septic tank and any buried gas or telephone lines on the property before you build. This information should be available in your town office and property deed respectively. If not, the town clerk should be able to direct you where find this information.
Costs associated with building an addition
Since building an addition is similar to building a home, it has many of the same fees. You will need to pay the contractor for the work on the home addition as well as the cost of the materials he uses. These costs will vary based on whether you choose hardwood, carpet, tile or linoleum floors, how large an addition you have planned, and the utilities you need to run to the space. Be aware of inspection fees and building permit fees to ensure the work is done legally and safely.
An overview of how to build a home addition
