Looking to remodel your kitchen or bathroom? Look no further than 5 Star Home Renovations LLC. With over 15 years of experience in bathroom remodeling, we are your go-to experts. Contact us today for a free estimate!

"Started out well. Job started earlier than originally planned which was fine. Paid a third down to start job with understanding that rest would be paid in full upon completion. Everything was going fine until near the end of the job. After shower fixtures were installed I noticed they were the wrong finish from what we agreed on for the estimate. Took a week for Joel to reorder & replace. When the frameless glass shower panel was going in, the installer realized it was the wrong size, and had to be redone. The grout on the stone shower floor was very sloppily applied. Bits of dried grit are stuck on the stones. Before job was finished Joel was asking for full payment as he was running tight of money. I insisted on paying him in full only when job was complete. He wasn't very happy. Overall, the tile shower walls & bathroom floor tile look great. I only wish there had been more attention paid to the other details."

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.
