Your Home Addition questions, answered

Answers to commonly asked questions from the experts on HomeGuide.

What is a home addition?

A home addition is a new structure added to an existing home. Home additions create more living space, accommodate a growing family, and improve the home’s overall value.

A home addition can be completed by making a single room bigger or adding an entirely new room or second story to the home. A more affordable home addition option is to convert an existing garage, basement, or attic into a more functional and comfortable living space.

Does a home addition increase property value?

A well-built home addition can increase property value. The increase in square footage adds value, especially if the addition includes functional and well-designed living spaces. An addition that adds an extra bedroom, bathroom, or larger kitchen can make the home more appealing to potential buyers.

How can I finance a home addition?

You have various financing options for a home addition, such as:

  • Home equity loans – These bank loans allow you to borrow a lump sum by using your home equity as collateral.
  • Home equity line of credit (HELOC) – Unlike a lump sum, this revolving credit line enables you to borrow against your home equity as needed.
  • Cash-out refinances – By refinancing your mortgage for an amount exceeding your current balance, the lender provides the surplus in cash, which can be used for home improvements.
  • Personal loans – Unsecured and without collateral, personal loans have higher interest rates, determined by your creditworthiness and loan approval.
  • Credit cards – Consider using a low-interest-rate credit card for smaller home additions, ensuring prompt repayment.

How can I save on a home addition?

Consider the following recommendations to reduce the expenses associated with a home addition:

  • Opt for a straightforward design with minimal features to keep costs down.
  • Construct the smallest addition that satisfies your requirements and complies with local regulations.
  • Explore the option of repurposing existing spaces, such as basements, garages, or attics, which is generally more affordable than building a new structure.
  • Do basic tasks like painting and interior finishing on your own to cut down on professional labor expenses.
  • Select budget-friendly building materials and finishes in more spaces, and splurge on a few items with the most impact.

How do I choose a home addition builder?

Follow these suggestions to get the best home addition contractor near you.

  • Seek estimates from several contractors for the same addition size and features, allowing for informed comparisons.
  • Evaluate the builder's reputation by checking recent reviews on HomeGuide and Google to assess their performance.
  • Request a site visit to see the contractor's construction methods and gauge their workmanship firsthand.
  • Choose a contractor with proven experience in the specific type of home addition you desire.
  • Protect yourself by requesting an itemized written contract that outlines the scope of work, specifications, and payment terms to prevent any misunderstandings.
  • Inquire about the contractor's preferred lenders to streamline the financing process and potentially secure better terms.
  • Exercise caution and avoid making large upfront payments. Never pay in full or in cash, as this could leave you vulnerable to potential issues.

What questions should I ask a home addition contractor?

Here are some helpful questions to ask a home addition contractor:

  • How many years have you been specializing in home addition projects?
  • How many home additions have you successfully completed within the past year?
  • Do you provide design services to help create a floor plan for the home addition?
  • Can you provide me with a list of references from previous clients, along with their contact information, so I can gather feedback on your work?
  • Do you have a portfolio showcasing your past home addition projects that I can review?
  • Are there any recent home addition projects I can visit to see the quality of your workmanship firsthand?
  • Are you fully licensed, insured, and bonded to protect me from any potential liabilities?
  • Can you advise me on the most suitable locations for building an addition to my home?
  • Can you provide me with a detailed cost estimate for the home addition project?
  • Are there any cost-effective strategies we can consider to reduce the overall expense of the project?
  • Can you provide a realistic timeline for completing the home addition project?
  • Who will be my designated project coordinator responsible for overseeing the project's progress?
  • Do you employ your own experienced crew, or do you subcontract the work to other contractors?
