"If you need work done promptly, with high quality, and for a fair price, HIRE COASTAL C&C!! From start to finish Claudio and his team exceeded my expectations. Claudio asked excellent questions while visiting to prepare a quote, and made a handful of recommendations that ended up saving time and money and producing a better finished product. I received the quote just a day or two later, and it was the only quote out of five different contractors that immediately seemed like a fair price for the work. The whole team; Claudio, Dan, Bruno, and Jameson, were respectful, diligent, tidy, and clearly experienced. They were able to work independently and make good decisions in real time to keep the work moving without delay. As a result, they knocked out in a week what could easily have taken two or more. Communication was very easy. Claudio responded immediately over text, and at several points Claudio or one of the team approached me to request my preference on materials and other choices. I made several comments during the work, for example asking if there was a way to fill in some existing gaps between siding planks, and without hesitation they just took care of it. They even fixed or improved at no extra cost a few existing items that obviously needed doing, but I wasn’t going to ask them to do, just because they had the tools and were already there. I requested a few larger extra items while the work was ongoing, and Claudio offered the same very reasonable pricing for the changes and fit them in with no hassle at all. At the end of the project, the work all looks great, and I couldn’t be happier. I would recommend Coastal Counters and Cabinets to anyone, and without a doubt I would call them first with any future project. And don’t let the name fool you, they can do framing, painting, light electrical, doors/windows, concrete, and I’m sure much more! These guys are the best!"

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.
