"Excellent! The Sundogs, crew of 3, did a marvelous job of changing my wet and moist basement into a beautiful apartment. Floor was removed and a subcontractor hired to replace the floor after complicated drainage system and sump pumps were installed. Due to the small crew and the complicated problems, it took longer to finish, but I have now a beautiful apartment in my basement. They are dear and honest people who work hard. Thank you Sundogs!"

Mt. Tabor Construction offers general contracting services including all phases of remodel projects-kitchen, bath, basement, attic, plus, electrical, plumbing, fencing, gates, decks, painting-interior/exterior, drywall and plaster, landscaping, as well as home repair/handyman services.
"I live just down the street from Rob and I had a simple task I asked completed of caulking in the shower. Whether his work was faulty or the product was faulty I don't know, but three times it didn't work. I try not to make assumptions about people. All our conversations have been via text, so I have a full written accounting of what happened. After the last time did not work, he offered to redo it once more or provide a refund and I immediately replied back that I would accept the refund and wish him well. He was going through some family health issues so I didn't press it and I waited to hear from him. Instead of honoring my wish to move forward with the refund he offered, in writing, and I accepted in writing, he tried to schedule a time to redo it. He then says he didn't mean to offer a refund and he refuses to honor it now. He told me I should just file a complaint and "try to ruin his reputation". Just another reason why it's best not to involve neighbors in professional endeavors. I'm sad it turned out this way."

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.
