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?

Albert and Susan are masters at helping clients determine what their vision is for a space and then making it happen. They adhere to your design aesthetic but will always offer an additional suggestion to help elevate the room- offering an expertise that you might not have. Albert and Susan insist on top quality and only work with contractors and vendors that can deliver it. They are also wizards at finding good quality but less expensive options for high end looks.
