Biango Construction strives on giving all of our customers the best quality craftsmanship and pricing in the industry. Locally owned operated. We guarantee your satisfaction! Free estimates.
"I had Biango Construction complete a full gut renovation of my main floor powder room and laundry room/mudroom. This included a major change in layouts and moving walls, doors, HVAC, plumbing, gas lines, and electrical. I also had custom cabinets and hall tree built for the space. The final result is exceptional (see photos). While the time ended up taking longer than originally expected, it was worth it to have a trusted pro do the work and to deal with the permit process. The company was easy to work with, professional, and maintained a clean workspace across my house. All individuals working on my house with Nick Biango paid high attention to detail throughout the entire process. I would highly recommend Biango Construction to anyone doing renovations or wanting built-ins added to their home."

"Larry and his team were absolutely the best. We had some repair work that needed to be done as well as electrical and installation of a bathroom with tiling and plumbing. Larry is VERY good with communication before, during, and after the work was completed. He and Dave went over and above what we expected and were extremely competitive with pricing for us. They even went so far as to fix some issues that only added to our enjoyment of our new basement and bathroom. We had a terrible experience with a former contractor and were a bit shy about hiring another but I am so glad we did! From top to bottom, they performed like professionals and completed the project in exactly the time they specified. I will hire these guys any day of the week and would recommend them to others in a heartbeat."

"What can I say about Dan and crew? If there were six stars, I would have given them all of those! Our powder room job was also flooring for the hallway and laundry room, plus a utility sink. It was a total gut job in the bathroom. Dan could not have been nicer, quoted us a more than fair price and the job was finished in record time. He was very responsive to any questions we had (ok mostly me). Also, his workers (2) were fantastic. I'm not sure if I should name them, so I won't. They were efficient and professional, asked questions when needed and cleaned up the site and their work space (our garage) every single day. They treated our home with care, as well as our old appliances and new fixtures. We could not have been happier with all of it."

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.
