"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."

"If you’re on the fence about hiring D2A Construction—don’t hesitate. We just wrapped up a full kitchen remodel, and the experience was night and day compared to past renovation nightmares. Dani was our project manager, and he was not only knowledgeable but honest and straightforward throughout the entire process. What impressed me the most was the communication. Dani gave us weekly updates, coordinated every inspection, and was quick to pivot when we made a few last-minute changes. He helped us find beautiful tile and cabinetry options that fit our aesthetic and budget, which is not easy to do. The workmanship was top-notch. You can tell the team takes pride in what they do—from the smooth finish on the cabinets to the precise tile work around the sink. They finished everything in a timely manner, and there was very little downtime between stages. I’ve already referred them to two coworkers. Dani and his crew are the real deal!"

*Please Call Directly* WE SPECIALIZE IN COMPLETE REMODELING PROJECTS WITH A MINIMUM COST OF $5,000. We are a team of skilled craftsmen each with many years of experience remodeling kitchens and baths in the Orange County area. At Coastal Kitchens Inc. instead of a showroom we use door style, finish and kitchen cabinet samples, as well as photo design books and CAD on laptops to display your kitchen as it is designed. This way we eliminate the need and the cost associated with a showroom business model. This makes the design process more convenient for our customers, and we pass the significant savings on to them as well. Our design process also allows us to spend more time working on our customer’s designs. This is what we enjoy most about our business and it is what makes the difference between an average and a great kitchen design. Why should I work with Coastal Kitchens Inc.? John (the owner) has 34 years of experience in the remodeling field along with his experienced team. Our top priority is ensuring you receive the highest value for your dollars. This means we will sometimes suggest less expensive options for some aspects of your kitchen to accommodate better investments for others. For example, we can often recommend a cabinet door style that will appear identical and cost substantially less leaving you more dollars for your overall renovation. One of our guiding principles at Coastal Kitchens Inc. is that the best investment in your kitchen is always your design first and your door style second. Exceeding expectations, but never your budget. Contact us through email at coastalkitchens@cox.net for faster response. Credit card purchases are welcome however we charge a small convenience fee.
"BEWARE OF COASTAL KITCHENS & BATHS! This review is for a complete remodel of our master bathroom that occurred in early 2024. This business has no BBB rating. This business has no employees. This business has no presence on Houzz, Angi.com, Home Advisor, Yelp or any place else online and no website. Everyone who works for John Bailey is a sub-contractor. His subs vary widely in quality. Some are good and some are not. His idiot painter tracked white paint all over our master bedroom carpet. When I complained to John about that he responded that we were going to replace the carpet anyway and so what! His sub-contractors had to access the bathroom by going through our master bedroom. THEY DIDN'T EVEN PUT DOWN DROP CLOTHs. When I complained to John about that he had them put down tarps that were so filthy that it made our floors even worse than before. When it came time to install the vanity countertop the supplier (Best Cheer Stone) delivered the wrong countertop and John didn't even notice! My wife caught the mistake. John pressured us into accepting the mistake by telling us there would be a 2-3 week delay in the project if we insisted on returning the countertop. He did get us a discount from the supplier but it’s still the wrong countertop. Recently I noticed that one of the bathroom floor tiles had cracked only 10 months after installation so I called John to see if he would replace it. He told me he would talk to his tile guy and get back to me. A week later still no response so I called him back. He clearly did not want to accept responsibility and told me that replacing the tile might damage other tiles. This is nonsense because I have had 3 tile contractors look at the job and none of them said anything about that. When I tried to get John to accept responsibility for the cracked tile he got mad and hung up on me! BEWARE OF COASTAL KITCHENS & BATHS! John Bailey is super sketchy and will blow smoke at you all day long to get your money. He does not guarantee the work and will leave you with a $600 extra charge for tile replacement. I have other complaints too but in the interest of brevity I will stop here."

FAQs for guest house building service projects in Rancho Santa Margarita, CA
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.
