My clients and I are always elated with their service and their ability to deliver outstanding results promptly. I highly recommend OT Bay Builders, if you feel your home is outdated or if you are looking to increase the value of your home for an upcoming sale!"

"Josh did a great job on my roofing repair! He showed up when he said he would, and the roof looks great! He also installed some replacement skylights and siding. He sent many pics of the job as I wasn’t able to be there when the work was performed. I will definitely use him again."

"On a scale of 1-10, I would rate Brother and Brother Builders an eleven. Their professionalism, knowledge, craftsmanship, and courtesy were truly exceptional. During the initial meeting, the senior project manager Daniel Perez carefully guided us through the process and was available to answer any of our concerns. Then throughout the project, he checked in on a regular basis to ensure the process went smoothly and made sure everyone stayed within the projected timeline. The interior designer was amazing and extremely talented. I always appreciated how she listened to my thoughts when creating the final design. She was also readily available when needed. The foreman and crew were hardworking, respectful of our home, and accommodated our requests. The final product was beyond fabulous and we are extremely happy with our renovated kitchen and family room."

"We needed a new kitchen, since ours was seriously out dated. We have some ideas of what we wanted, but was hoping for some professional input. We hired Eli with Cal Green to do the job and had hoped we made the right decision. In the end we did. Eli was very knowledgeable, patient, and caring. He made the process go very smoothly and handled all the permits and dealings with the city, which was a relief for us. He took our ideas and included some of his and the kitchen came out great we are very pleased with everything. I would recommend Eli for any work you're considering for your home. For our next project we will definitely be using Eli and Cal green remodeling. Thank you so much Eli for a wonderful experience."

"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

Barndominium Builders FAQs, answered by experts

Technically, most states allow tiny homes, but it depends on the definition of tiny and whether the structure is permanent. Zoning laws regarding home size and construction are significant factors. For instance, a tiny home may be legal as a recreational vehicle in most areas, but you may only install it on a property if it complies with building and zoning codes.

The most common slope, or roof pitch, for a shed is 4:12 or four inches of height for every horizontal foot. For areas that experience heavy snow loads, a steeper roof of 6:12 or 9:12 is best. 

The maximum size of a tiny home you can move depends on your state transportation guidelines, but the rule of thumb is a maximum of 400 square feet. However, as long as it falls within the local limits for traveling on public roadways, you should be good to hit the road.

If you’re building a pole barn in place of a traditional home, lenders usually don’t offer traditional mortgages for these structures. You can also expect higher insulation costs and building permits may not be allowed in your area. Even if you’re just using a pole barn as storage or as a shelter for animals, these structures are less durable than steel buildings and require more maintenance.

You can use a variety of wood to build a barn door, but the most common options include 1-by boards and 2-by boards for the backing and the decorative boards on the front of the door. Softwoods like pine will save you some money and should hold up well, while hardwoods like maple and oak will stand up to more wear and tear. You could also build the backer out of plywood to minimize the cuts you need to make. Whatever you decide on, make sure the width of the wood is compatible with the mounting brackets you buy.
