"service provider sent by American Home Shield was excellent. The only issue I have with home warranty services is that they do not send their repair companies out on the week-end, even in an emergency. The customer service personnel is less than enthusiastic or helpful."

"The project went really well and I'm super stoked. Some of my ideas changed as we went through the quote and planning process and Charlie went along with my ideas and gave me feedback. My driveway and yard are exactly how I wanted them. I have an amazing tiered front porch, new side patio and steps, and expanded driveway on both sides. I'm super happy with the work and how everything turned out!"

Custom Home Builders FAQs, answered by experts

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.

Building a house without blueprints is not advised. It will prevent you from obtaining necessary building permits and meeting building codes and is likely to result in shoddy construction and unsafe living conditions. Detailed blueprints ensure that a house is built to exact specifications and is constructed safely and structurally stable.

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.

Start by researching local contractors with experience in cottage construction. Ask for references, check licensing and insurance, and review completed projects. Compare multiple bids, making sure each includes the same scope of work. A good contractor will communicate clearly, provide a detailed contract, and ensure all work meets code and safety standards.

A carriage house is a freestanding building, while a townhouse is connected to other units. A townhouse is a full single-family home and typically shares a parcel of land with other connected homes. A carriage house is rarely used as the sole single-family home on a property and is most often an additional building sharing property with a traditional single-family home.
