Architectural student -turned engineer -turned entrepreneur. As a builder contractor in the field for over 30 years, I understand that honesty and integrity come first. I run a crew of four men, who I conduct on the job everyday and I am always on the job site. I'm now 30 years in business successful and still dedicated to my client's total satisfaction. Trying and succeeding to do a professional job for one important person at a time - you.
"Tanem has a long history of good work. Gene did several projects for me years ago and I was glad to find Paul picked up the same qualities Gene had established. Both are easy to work with, knowledgeable, make lots of helpful suggestions so the project comes out even better than I had thought it would. You tell Paul what you want done, and he, and Gene in an advisory role, find a way to make it even better. They are flexible and just know how to find solutions. Their crews know what they’re doing. Paul keeps checking and keeps you informed as work progresses. I couldn’t be happier to see Paul continuing the Tanem tradition."

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.
