Average rating: 5 out of 5 starsOctober 26, 2023
“Our kitchen looks gorgeous- we absolutely love it. The foreman, Stevo, is incredible and we recommend him to everyone who is looking for a remodel. He is detail oriented, asks great questions to help ensure that we want what we are asking for and provides excellent advice/thinks through what we really want and what the most cost efficient solution is. We trust him and his gorgeous work speaks for itself. The communication is slow before a job/to get quotes but during the job but he is 100% invested in that job and highly communicative.”

KD Builders LLC
ADU Contractors in Chester County
Average rating: 5 out of 5 starsDecember 11, 2020
“I think most people write reviews when the work is just finished or even during the process. I wanted people to know that I purchased my new home about a year ago and taking care of various issues after the sale is done is extremely important to us. Kevin and his teams not only built our home, but they are also there for us when we need them. Some of these issues were not the responsibility of KD Builders but they took the time to help us solve these problems and in one case fixed it without charging us. Beyond their impressive expertise, every member of Kevin's team is friendly and a pleasure to work with. They proficiently address the issues and are able to clearly explain the process to a layman. In short, they are skilled, knowledgeable, and they really care about their clients. We highly recommend that you if you have a project for your home that you give them a call.”

Hazley Builders
ADU Contractors in Chester County
Average rating: 5 out of 5 starsJune 27, 2013
“There isn't enough space here to tell you how happy we are with the professionalism, attention to detail, willingness to stand by their work and easy-to-work with qualities of Hazley Builders. This is a father and sons business and Mike Hazley Sr. believes keeping customers happy, even after they have completed the job, sets them apart from other contractors. He is right about that. They constructed a new addition for us that is handicap accessible (new sitting room, bathroom, dressing room and closet) and it is beautiful. They went the extra mile with so many things, like reinforced beams, extra insulation, etc. When we had a problem with the new toilet about 6 months after the renovation was completed, Mike's crew was here to solve the problem, which was a manufacturer's flaw. His workers were careful about heeling in bushes and other plants that I wanted to preserve which they had to dig up to pour a new foundation for the addition. They replanted them once construction was done and everything lived and is thriving. I could go on and on. My best recommendation is the number of times I have recommended Hazley Builders to friends, relatives and acquaintances.”
Jibe Design
ADU Contractors in Chester County
Average rating: 5 out of 5 starsSeptember 13, 2017
“The centerpiece of our home renovation was a floating, black walnut spiral staircase envisioned by Jibe Design principal Juliet Whelan. It is breathtaking, and brings architectural distinctiveness as well as light into our row home. The project also gave us several more feet of precious space thanks to the removal of a chimney we did not realize was behind a wall. Whelan came into our space and saw all kinds of fresh possibilities, but also succeeded at learning and honoring our aesthetic. It was a pleasure to work with Jibe Design. From start to finish, we appreciated the design sophistication, professionalism and good communication.”

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 Chester County. 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 Chester County: 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.
