"Aventus completed a 1600 sqft 2bedroom 1 bath addition (in-law suite)for my home. Communication was excellent. The project manager Brianda worked closely with me throughout the project. The permit process is very lengthy and we had some material back order delays but the process overall was timely and I couldn?t be more pleased with the outcome."

Brown's Construction, Inc., provides the highest quality work at an affordable price. We listen to our customers needs and we execute their ideas to near perfection. Customer satisfaction is our number 1 goal!

"Great work when it is done right, but some mistakes should not be made. To completely frame the whole build crooked and have to tear down and rebuild is ridiculous. I am still dealing with water leak issues from the build. There were other projects i had planned for them, but I have had a change of heart. "

"Miguel and his team were fantastic. His price was very fair, and the quality of his work was top-notch. We had his company remediate my attic flooring system and fix/reinforce a few truss members in the roof. The work required a lot of demo and movement of large materials throughout my house. Nothing in my home was damaged while they worked. The members of the crew were very polite and professional. Miguel kept me informed and communicated effectively. I have dealt with many contractors over the last few years in Indianapolis, and I can say without a doubt that this is the best contractor you can find in the area."

"My family experienced water and wind damage earlier this year. We had to be placed in a hotel. After reaching out to numerous companies, we chose Maynor construction. I am glad we did!! If it wasnâ t for Maynor and his staff, I wouldnâ t have made it. The process was long and depressing because of being away from home. However Maynor and his staff reassured me. They showed patience with me and worked hand and hand with my insurance company with getting my home repaired in a timely manner. Thank you Maynor! I truly feel like we are family!"

FAQs for addition to existing structure building service projects in Indianapolis, IN

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite. 

An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
