Building your dream home is going to be one of the best purchases you’ll ever make in your life. Whether it be money or happiness, you will never regret this decision. There are many things you can choose when it comes to building a Custom Home Builder —from each design aspect to the size of each room, materials, and how efficient your home will be. Building a dream home will take a lot of work and communication. Asking your builder these questions will allow you to gain more knowledge before starting the construction of your new home. If you are looking to build your dream home in the greater San Antonio area, Boerne, or anywhere around the Texas Hill Country, here are 12 questions to ask your builder.

12 Essential Questions to Ask Your Custom Home Builder

1. What type of contract do you use: Fixed Price or Cost Plus?

Knowing what to expect with your budget is key when building a custom home. Ask your builder what kind of contract they use to build your home. If your builder uses a fixed-price contract, you will know exactly what your home will cost at the end of your build, allowing you to not worry about being surprised by a large bill. Make sure your builder walks through the lot and gives you a detailed quote before you sign anything.

2. Do you use engineers to build your foundation?

When building your custom home, you want to know that it is structurally sound. There are many types of soils around the Central Texas and Hill Country area. Make sure your builder knows what your home will need to support its structure—whether it’s the foundation or the roof of your home. They should have an engineer look at your lot and what is needed to support your new home.

3. Can you build on my lot?

If you have land or are thinking about purchasing land to build your home on, make sure you ask your builder if they can build on your lot. Slope, drainage, trees, and utilities are all factors to consider when building on your own lot. Your builder should be able to walk through your property and give you information on how to best build your home on your property.

4. Who will be my point of contact when building my home?

There are many contractors that come and go on your jobsite. Knowing who you will speak to throughout your build is very important. You don’t want to have to tell your builder what you like and then have to repeat yourself to every subcontractor. A good builder will send you pictures and regular updates on your custom home as it progresses.

5. Will you take care of building permits?

Building permits can take some time, and it’s something you may not know about. Make sure your builder can pull permits for you and knows what they need from you. Some cities require HOA approval before they will allow you to build. They should also know how long it takes to get permits in your area and give you a timeline.

6. How long will it take to build my home?

When building your custom home, it will take some time to get finished. Depending on your floor plan, it can take 8 to 14 months to build your home. Ask your builder for a timeline and what steps they will take to get your home finished. Weather or backorders can sometimes delay your build, so know what they will do to keep you on track.

7. What are your options when choosing your finishes?

When it comes to your finishes, you want them to be something that you love. From cabinets to stone and masonry, there are endless choices when building a custom home. Ask your builder what they offer to help you pick out your finishes—maybe they can show you pictures or even a 3D render of your home. You want to know that your builder can order these items and will have them in a timely manner.

8. Can I customize my floorplan?

When you decide to build your home, you want it to be customized to your family. There are many options you can add to your home that may fit your family better. Ask your builder if they can help you with your floor plan. Whether you want to add a second story or make your primary bath bigger, they should be able to help you customize your home to fit your family’s needs.

9. What happens if I want to change something during my build?

You may want to change something while your custom home is being built. Maybe you see something you like or don’t like about your floor plan. Make sure your builder can help you with this. Your builder should be able to write up any changes you want to make, letting you know how much it will cost or save you and how it will affect your timeline.

10. What quality control do you have in place?

Before your walls are closed off, there are many things that need to be inspected. Your builder should have quality control checks in place to make sure everything is done correctly. They should inspect your home for squareness and level, and ensure your wiring and plumbing are up to code.

11. What kind of warranty do you offer?

Once your home is finished, you want to know your builder will stand behind their work. Ask your builder what kind of warranty they offer. Some builders offer a 1-year workmanship warranty, and they should also be able to help you with any issues you may have after your custom home is built.

12. Can you show me examples of your work?

One of the best things you can ask your builder is to show you examples of their work. Ask them for references and, if possible, visit some of their homes. This will allow you to see what they can do and how they communicate with their customers.
