"Luis did an excellent job creating a laundry room for us. He converted part of our garage into an amazing room - you would never know it was once part of the garage as it flows seamlessly into the house. The herringbone tile floor installation was excellent, as well as the cabinets/doors/wall installation. Luis also had a team that managed plumbing, electrical, and hvac work. We are so happy with the space and always receive so many compliments. Luis is super easy to work with, strong attention to detail and has a great attitude."

We pride ourselves on being a unique construction company. Everything Under the Roof is an interior, residential construction company owned by Kim and Jay Spanier. At work we are a husband and wife team, but at home we are mom and dad, so we truly understand the importance of keeping your project orderly and on time, while keeping your family (including your pets) safe. We can also guarantee NO high pressure sales calls, and no crabby, condescending construction guys working on your home improvement project – just our family helping yours! Kim is your main point of contact through the project. She walks you through the construction process, acts as your personal construction jargon translator, and, most importantly, she is the budget master. Kim will help you shop for materials so that you stay on budget. Jay is the jobsite superintendent. He manages the day to day activities of your remodeling/construction project, he coordinates and manages the sub-contractors, and it’s his skillful carpentry that will transform your home. All of our projects work within the existing footprint of your house. What exactly does that mean? Well, in a nut shell, we don’t do additions, and we won’t raise your roof. We find all the hidden, un-used spaces in your house and re-create your floor plan to work for you and your family.

"Kim and Jay are the best contracting group I have ever worked with. Thorough, responsive and always friendly and courteous."

Guest house building services FAQs

In most states, yes—you can build a guest house, but every city or county sets its own zoning rules and building codes. Before breaking ground, check local ordinances, confirm lot setbacks, and secure the right permits. A local contractor or design-build firm can walk you through the paperwork and site requirements so your project starts on solid legal footing.

Yes—homeowners often tap a few different financing tools. A home-equity line of credit (HELOC) lets you borrow against your equity as you need funds. If you prefer a lump sum tied directly to the project, a short-term construction loan can roll into a second mortgage once the build is complete. Cash-out refinancing is another option: you replace your current mortgage with a larger one and use the difference to cover construction costs.

When you build a guest house, you’re creating a separate structure for hosting visitors without the full amenities needed for permanent living. An accessory dwelling unit, however, includes a complete kitchen and bathroom, meeting building codes for a long-term residence. This key difference makes an ADU ideal for long-term occupancy or rental income, adding enduring value to your property.

How many rooms you need depends on how you plan to use the space. Aim for one bedroom per every one or two occupants to make sure everyone has enough privacy and comfort. Added living and dining areas give you extra functionality, especially for rental use or long-term stays.

Most homeowners pick somewhere between 600 and 1,500 square feet to fit all the essentials. Make sure your design supports one to two occupants per bedroom and includes enough common areas for comfortable daily living. A well-proportioned layout boosts both functionality and property value.

No—a guest house isn’t just a bump-out on your main home. A bump-out is a small extension within an existing room for extra seating or storage. In contrast, you build a guest house as a standalone building with its own foundation and amenities, giving you a fully separate living area that can boost your property’s versatility and value.
