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.

Hiring a reliable home builder is an essential task, but there are a few questions you can ask a potential builder to ensure you they are trustworthy and up to the task:

  • How long do you expect the process to take?

  • Are you fully licensed and insured?

  • How much of the work will you subcontract?

  • Will you pull all of the necessary permits for the job?

  • How long is the builder’s warranty you include with your work?

  • How do you handle resolution for issues I might have with the finished product?

  • How much experience do you have?

Whether a prefab home is worth it or not will depend on your personal needs and preferences. Overall, prefab homes tend to cost less than traditional homes, although they also tend to have lower resale values. Another thing to consider is that prefab homes usually last 50 to 60 years or longer, while traditional homes last 50 to 100 years or more.

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.

It’s typically more cost-effective to move a building along with its accessories than to demolish and rebuild it from scratch. However, that’s only if you can move the accessories without damaging them. However, if you plan to demolish the accessories anyway, it is advisable to do so before the move to save costs.
