The guys were professional and polite, answered all my questions, stayed focused on the job at hand, kept things tidy, and arrived and departed on time. I'm so pleased with my bathroom renovation.

Properly licensed & insured construction company located in Northern New Jersey.

"We hired the Mazepa Group to gut and reconfigure our master bath. This was a bigger project than we realized and Devin was helpful at every step. He advised us on different ways to configure the space, offered his experience in working with different materials, and was understanding when we inevitably changed our minds on what we wanted to do as we went along. He is very easy to work with. His crews were friendly, professional, and dedicated to customer satisfaction. They took obvious pride in doing careful work and keeping the work area as tidy as possible. We would gladly use the Mazepa Group again."

"I recently had the pleasure of working with Modern Knight Designs LLC for a kitchen remodel, and I couldn’t be happier with the results. David and his crew were professional and friendly throughout the entire process. David brought samples and walked me through every step, ensuring I was comfortable and informed. The quality of the cabinets and the overall work was exceptional. They even customized a few cabinets to perfectly fit my space, and the craftsmanship was top-notch. We went with modern blue shaker cabinets, which we get lots of compliments on. Additionally, the job was completed on time, which made the experience even more satisfying. I highly recommend Modern Knight Designs LLC for anyone looking for quality and professionalism in their home renovations."

We are masonry contractor company that specializes in the installation of outdoor living areas including paver driveways, walkways, patios, steps, stoops, retaining walls, culture stone, and fire pits. We are fully insured.

"Classical Pavers did a beautiful job replacing my front walkway! It was not a straightforward project because it was built on a steep slope with a curve. The owner Thiago, who oversees the project, was a pleasure to work with -- never used any pressure tactics, was very responsive to any questions, and gave a fair price. The two craftsmen who did the work were amazing! They arrived promptly every day, worked extremely hard, and did absolutely beautiful work. They hauled away all the old materials and tidied everything up when the job was done. We definitely would hire them again for a future project and highly recommend them."

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.
