"Let me start by saying, this ADU project was for my daughter, Macy. Macy has I/DD and Autism and will likely not be able to live away from us, her parents, unless she is in assisted living of some sort. However, together with her grandma we sought to create an environment for her to live as independently as possible and for her to grow into. This began our search for the perfect contractor who would understand our needs and work with us to build this ADU for Macy. Enter, Jay Bemis with Timeless Builders. After multiple meetings with contractors, many unreturned calls and emails, we met Jay. He immediately sounded interested and returned with a bid in a timely matter. We accepted this bid and began to move forward with this project. As with any construction project, we ran into unexpected situations. I could not have picked a better partner to handle all of these situations. He maintained focus on finding solutions, worked magic to make things happen that we wanted and came up with additional creative ideas when we couldn’t. He is a true craftsman and he employs the most amazing people! The pandemic hit during our project and he was respectful of our request to wear masks when entering our home. They continued the work and Jay was open about end dates and timelines. If you are looking to start a project, I can tell you that Jay Bemis and his team at Timeless Builders is who you want to partner with. Their work exceeded our expectations, their friendliness was an added bonus and the end result blew us away. Don’t think twice, contact Jay with Timeless Builders, he will help you get your project done right."

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."

FAQs for guest house building service projects in Portland, OR

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.
