Remodel or Renew Home Improvement Inc. is a family owned team of contracting professionals helping homeowners throughout Massachusetts. Brothers Mike and Tom teamed to form RORHI in 2017 combining their years of experience as general contractors. We provide services in all aspects of home improvement but tend to specialize in decks, siding, paver, patio, and basement remodeling and installation. RORHI has been awarded the #1 Trex deck installers for the last 4 yrs.

"I was with the contractor that made me think that because my good credit I was getting a good financing interest around 7% and he did not tell me that my granite steps had to be removed, he told me after the loan went through at a rate of almost 14% at this moment I would like to cancel the project, I am under a lot of stress and having back issues I am afraid that because I take time off from work I am not going to be able to pay for this high interest loan."

"I took a chance on hiring a young construction company to do some serious work around my house. Overall, their work ethic and professionalism just blew me away. Build Simple Inc.’s. Four-man team arrived every day and worked from 8:00 A.M. to about 6:30 P.M. every day. There work was impressive. In eight days they: • repaired rotting wood on garage • replaces seven existing windows and an entrance door • vinyl sided the garage • installed new gutters • demolished front porch and installed a new composite deck The workers were friendly and kept me informed as the project progressed. Everything came out amazing and I would recommend Build Simple in in a heartbeat."

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.
