"Dalton and his crew were hired to build a roof over an existing deck and replace a rotting fence. From the get-go, they were professional and hard working. On time and efficient, they kept us informed every step of the way. The result? What seems like a beautiful new porch and yard! We even went on to hire them for an additional project, replacing trim on our home. And the cost? Quite reasonable! We highly recommend Elk Valley Construction, LLC!"

"They seem to know what they’re doing and they are just straight up about things.  We are gathering information to provide them like cabinet sizes and countertop material.  They can’t submit the bid until we have all that other stuff gathered up and we can tell them what they want in the way of appliances, countertops, and cabinets."

"I was very impressed with Sentri Homes - their customer service was excellent. They sent a subcontractor to install some vinyl laminate in my bathroom and he ended up getting glue all over the carpet in our bedroom. The sub ended up ghosting both me and Sentri, leaving me stuck with a ruined carpet. Sentri stuck with me for over a month to get the carpet replaced with the identical original and to get the vinyl job 100% completed. The carpet was a Home Depot exclusive and Sentri handled everything with them. I will be using Sentri for a much bigger renovation I have coming up soon, because I know that they will make sure everything gets done right no matter what problems come up. The vinyl looks great too."

Custom Home Builders FAQs, answered by experts

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.

Builder-grade is one of two types of stock cabinets, whereas semi-custom designs allow homeowners some control over the color, finish, or hardware on their cabinets. Stock cabinets are sold in construction-grade and builder-grade designs. Construction-grade cabinets are usually made from inexpensive medium-density fiberboard, which is prone to moisture damage, whereas builder-grade models are a step up with higher-quality materials. Construction-grade designs are the most common type of cabinets in America.

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.

Typically, architects do not build homes in a hands-on sense of doing the actual framing, roofing, or other building. Architects usually do not have the training and experience to build the homes they design. An architect would need to know how to do the specific trades required to build a house, which is possible but not a common practice. A general contractor or homebuilder typically oversees the actual details of building the house that the architect designs.
