“We contracted with Todd Schulte regarding our upstairs dormer project, which enlarged bedrooms and reconstructed our bathroom. He was responsive and responsible,.

Studio Walker Architects, Inc.
ADU Contractors in Union
Average rating: 5 out of 5 starsMay 3, 2021
“I was looking for someone deeply experienced in technical domains, (architecture, construction, and fabrication) to fit the requirements of my custom home, the Galer Street House. Thomas was tasked with production of the interior custom cabinetry and associated custom woodworking. From our first meeting, Thomas’s communication, experience and broad background gave me confidence that he would understand the complex geometries and be able to deliver the high-end quality needed for this application. From the custom handmade walnut cabinets, custom furniture-like features and being always available to help me when the details needed his attention, he delivered. I was not disappointed. In addition, when challenged by architectural details and budget constraints on the exterior of the home, Thomas, owner of Studio Walker Architects, Inc., was able to take a large burden off my shoulders with his durable design/build approach, which was substantially less expensive and also resulted in a better overall appearance. Thanks, Thomas!”
Rainier Custom Homes

Average rating: 5 out of 5 starsFebruary 6, 2015
“Working with Rainier Custom Homes is a great pleasure. Their team is extremely creative, articulate, and well-vested in the happiness of their clients. What I enjoyed most was the collaborative process that their entire team was willing to participate in to make each phase of the project run smoothly and efficiently. I can't say enough about how well they communicate and meticulously pay attention to detail. And last but not least, they were extremely willing to follow my design plans! I am looking forward to more teamwork with them.”

An accessory dwelling unit (ADU) is a separate living space that can be added to your property. It functions as an additional dwelling on the same land where your main home is located. ADUs have their own amenities and entrance, providing a self-contained living area. Unlike a traditional home, an ADU cannot be sold separately and is considered part of the same property.

ADUs are subject to specific zoning regulations and building codes in Union. These regulations determine where and how an ADU can be constructed, ensuring compliance with local laws and requirements. It’s important to consult with local authorities or a professional contractor who is familiar with ADU regulations in your area to understand the specific legal differences and ensure your ADU meets all necessary criteria.

Consider these options for cost-effective ADU:
  1. Prefabricated ADUs: Affordable and easy to assemble, they’re a practical choice. Many prefab ADUs cost under $100,000.
  2. Traditional Construction: Work with an ADU contractor to find budget-friendly options and make smart choices.
Tips for cost-effective ADU construction:
  1. Define your needs: Determine the purpose of your ADU, whether it’s for family, rental income, or a home office.
  2. Consult a contractor in Union: Their expertise can help with cost-effective materials, designs, and planning.
  3. Prefabricated components: Consider using prefabricated elements like cabinets or bathroom fixtures to save time and money.
  4. Explore financing options: Look for ADU-specific loans or programs to help cover costs.
Ensure compliance with local regulations and seek professional advice. A knowledgeable contractor can make the process smoother and cost-effective.
