"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!"

We embrace the uniqueness of each development and we call our projects complete when each of your needs and wants are fulfilled.
"5++ stars! My home's exterior was cracking due to a poor job prior and drainage issues. Tom and Adam and the team not only gave me peace of mind moving forward with drainage, put in gutters, and re-did the entire exterior of my home (stained wood and stucco), but made it beyond beautiful!! They were communicative, timely, so easy to work with, and the end product is gorgeous. I would recommend them to anyone who needs a construction project done and can't wait to use them again on my next project!!"

"We are very pleased with our whole house remodel performed by our contractor, Rick Simmons of Coastline Construction. We received four bids from various contractors which were all competitive. We chose Rick for various reasons including that he was easy to communicate with and that he uses his own very skilled employees, no subcontractors. We completely remodeled the kitchen, the main and secondary bathroom, laundry room and installed new flooring throughout that required grinding and leveling the concrete slab. Every wall and ceiling was retextured and painted. It was a HUGE job. Rick is a hands-on contractor who stopped by the house 3-4 times a week (sometimes everyday!). Rick kept us up to date on scheduling and every addition we made to the scope of work was clearly documented in change orders that we discussed with him. We had a good idea of what we wanted design-wise and the end result reflects that vision."

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.
