Ryan L. says, "I hired Renovate Max to renovate my Menlo Park home after they were recommended to me by a close friend. I interviewed several contractors and hired Ali because he was willing to commit to an aggressive schedule and completion date with competitive price, no small task given the work involved. I was, and still am, thrilled with the high quality of the work that was done. Ali and his wonderful crew even worked late on Christmas Eve & New Year to make sure that my new kitchen was ship-shape and ready for me to host Christmas dinner. I always recommend Ali Erfan to my clients because of the many positive experiences that I have had with him, both on my own home and those of others.

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?

I hired LeCut Construction to remodel my mother's home since she has trouble communicating in English. I worked with Guy from the start to finish and was impressed with the level of communication from Guy as well as how they stuck to the timeline for the project. They make the process pretty easy by providing you with a design person to work with before the project begins to make sure everyone is on the same page about materials and design (if you don't already have one) and Guy was very flexible and accommodating throughout the whole process. The project turned out great and they made every effort to make sure we were satisfied with the outcome.

Fern with Bella Homes did a phenomenal job of our attic remodeling project. It was a complex construction project that involved reinforcing the foundation, replacing stud walls with shear walls, building a staircase, and fully converting the attic to a habitable space with a bathroom and a patio. Fern’s communication was stellar and he kept us updated on the project status. He was on top of any issues that arose and addressed them timely. Fern is a perfectionist and supervised the project with a sharp eye for the details. His crew is very experienced and executes very well. Fern managed the city inspections in a professional manner and we passed all of them with no rework! With a project as involved as ours, Fern was quite flexible in accommodating our input. He offered great advice on interior decoration decisions ranging from picking interior/exterior color of the house to setting up the fireplace with a distressed mantlepiece. Fern ensured that the layout, flow, and appearance of the house were in harmony and ultimately delivered the project to our utmost satisfaction.

Build the Bay completed a bathroom remodel for me - I was really pleased with the outcome and the process. Communication: Eitan and his team were communicative and ready to answer any questions I had. They explained the schedule and process in the beginning and throughout the project they shared updates & explanations. I felt well supported throughout. Build Quality: The work Eitan and his team completed sas great. There’s an attention to detail and cleanliness in the finished product that is exactly what I was looking for. For example, walls in any house are not perfectly even and corners are not perfect 90 degrees - Eitan’s team recognized these issues in my bathroom and adjusted the work so that the end result looked perfect (even if the underlying walls weren’t). 
When it came to things like tile design, Eitan gave attention to every inch so that the overall look was even & sophisticated. Timeliness: Eitan was willing to work with the schedule we had - it was summer so we had some time away and some last minute changes, but he was super reasonable & flexible. It was one less thing to stress about, which I appreciated. AND the project finished on time. Overall: I would definitely use Build the Bay again! We’re looking to kick off some larger projects in the future and I’ll go directly to Eitan for that work.
