"Joe’s team did exceptionally well in removing my old 2” x 12” and 2” x 2” patio lumber wall edge covers and posts, and replacing them with new ones. This task included painting the new lumber to match the existing lumber. The team even resurfaced the existing lumber to match the new. The corner edges of the lumber meeting together were well secured with proper lumber screws, and patched to a smooth seamless finish. Joe and his team stand behind the work they perform, and I assure you will be completely satisfied with their work. Well done team!"

"My wife and I recently decided to redo our walk-in closet. Because of my engineering background I drew up the plans and searched multiple cabinet shops throughout Orange County only to find that none except for one could provide me with the finished cabinets I hoped to get. Having been a customer of his for as long as he has been in business I should have realized that no one can compare with the craftsmanship that goes into each job that he does.

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.
