Fine Line Home Design LLC
ADU Contractors in Williamson
Average rating: 5 out of 5 starsApril 1, 2014
“I have been working with Tracy on designing a custom home for a property in Dickerson, MD. She has been an absolute pleasure to work with. She is very professional and extremely helpful in putting my ideas down on paper. She understands what the client desires and is able to offer suggestions that fit with their vision of the project. Tracy is also able to communicate well with the different parties involved with a project, from the structural engineer to the builder and everyone in between. I highly recommend her for any project!”

“I had an unfinished basement project and contacted THH. Cody and his team did a FANTASTIC job executing my vision! He reworked the layout, plumbing, electric, ventilation system, drywall and painting. Cody gave me new ideas and solutions to make the space more efficient! I highly recommend this company! So far I've had numerous friends contact him as well after seeing my finished space! I'm still in AWE of my space and the quality and professionalism THH provided!!!”

Alair Homes Hunt Country
ADU Contractors in Williamson
Average rating: 5 out of 5 starsFebruary 6, 2013
“We selected J&B over 4 other contractors to finish our basement and create a bonus room (laundry/craft/sewing room) over our garage. From beginning to end, J&B were consummate professionals - they were continuously available regardless of the day or time of day, they were courteous in both word and action and they were highly respectful of our home's private space. In addition to these important client sensitivities, J&B did exceptional work in our basement and bonus room - the attention to detail and workmanship was extraordinary; we frequently receive compliments about our basement and bonus from guests. While there were a couple issues along the way, J&B rapidly corrected the situation and made good on the work. J&B is a values-based company that is extraordinarily competent with fair and reasonable prices - I would hire them again in a minute! Superb!”

“Everything went perfectly. Megan took our house with ZERO curb appeal and turned it into one of the cutest houses in Ocean Pines, MD. The house turned out exactly as she presented it, as shown in the rendering. We could not be happier with the results.”
TML Construction

Average rating: 5 out of 5 starsSeptember 9, 2020
“TML installed a large deck and patio for us. We are so pleased with the finished product; both spaces look amazing!! We shared our ideas with Jeff for the spaces and he was able to conceptualize that into a project plan to include all the things we wanted. Jeff and his crew are knowledgeable, skilled and professional. They took great care in the detail work of both projects. Jeff was very easy to work with and prompt in his responses with us. They stayed on target for the time and the budget. Such a great company to work with!”

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 Williamson. 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 Williamson: 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.
