Sparti Mainline

Average rating: 5 out of 5 starsApril 10, 2017
“Peter Economou is exceptionally professional and does an excellent job on budget and on time. His company totally renovated two bathrooms for us. Not only did he help us with our selection of materials that were appropriate for our project but he took great pride in making sure that the projects turned out as we wished and are both beautiful and functional. Sparti also replaced our deck a couple of years ago. This was also a great project. We highly recommend Sparti Construction.”

Average rating: 5 out of 5 starsJanuary 23, 2018
“I recently remodeled my bathroom and living room with Cedars Construction. The workmanship was excellent and they went out of their way to make it as painless a project as possible. They cleaned up every day to minimize the dust and disorder, and were very knowledgeable and helpful explaining the process as they went along. They notified me when they were coming, and showed up each time. I would recommend this company for home remodeling and I plan to use them again in the near future.”

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 Philadelphia. 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 Philadelphia: 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.
