Find Addition to existing structure builders in Rancho Cucamonga

"Overall my experience with this company was great! The work that was done was really really good! Our contractor who assisted us was Jose. We added a living space and master bedroom to our home. The additions done look as if they were part of my house this whole time. Honestly it looks way better than I expected. The only reason I rated the company a 4.5 was because there was always some kind of miscommunication between our contractor and his workers. Don t get me wrong, things were always resolved, Jose was great at that. But my recommendation to is to make sure communication is #1. That way the customer is not confused or left wondering what will happen next. There was an issue with his floor guy though, he was rude and unprofessional. BUT the reason I am mentioning this is not to put down the company but let you know that we expressed concern for this issue and it was resolved professionally by Jose and it never became an issue again. The quality of work was top notch! His workers were all pretty cool guys and we always felt comfortable of who was coming into our home to do the work. I highly recommend this company for your next big project😊👍🏼"

FREE estimates and 10% off for Angi's List members! A.G.A Construction, Inc. is a licensed, bonded and insured, full-service construction company. We offer services in both residential and commercial remodeling including, but not limited to, new construction, room additions, kitchen and bathroom remodeling. Our mission at A.G.A Construction is to provide excellent customer satisfaction and top-quality work. We work hard to maintain high standards of exceptional customer service and superiority that has become expected of us over the years. Whatever your remodeling needs are, we take the necessary time to discuss with you the wide variety of options, products, styles, specification and your desired budget available in order to make your vision a reality. When working with our team you can be sure that your remodeling project will exceed your expectations. With any remodeling job, a project is only as good as its foundation. The same is true for our company, which is built on a foundation of trust and strong relationships with our clients. As our saying goes “When we are done, you will be happy, and until you are happy, we are not done.”

"We started the process of building our detached ADU at the beginning of 2022. We hired an Architect, who drew up a plan to build a 1200 sq ft, 3 bedroom 2.5 bathroom house. After 14 months of waiting and addressing revisions required by the Los Angeles Department of Building and Safety we got our permit in “Ready to Issue” status. While waiting for city approval, we all started looking for a fair, reliable and honest contractor who would do good/solid construction. We started the process of interviewing contractors and getting bids for the job. After several meetings and several bids, we met Micky Kanian with “AGA Construction”. We found Micky on Yelp. One of his references took us thru an ADU that Micky and team built for his elderly mother-in-law to live in. This family could not say enough good things about Micky and team. They took us thru the property and explained their experience in great detail. We saw another beautiful AGA project, a 5k sq ft + project that was in progress and really knew that day that we’d found our contractor. We weren’t quite ready to pull the trigger for personal reasons, so we put the project on hold. Meanwhile, we continued to collect a couple of other bids that were already in progress. During this process, AGA kept in touch with us. They checked in every few weeks or so, without being pushy or intrusive. After a delay of about 9 months, we decided to move forward with AGA construction. No one is a tougher critic than me. I was dreading this project because of the amount of stress that I knew we’d be under. Both financially and mentally. We’ve all heard and/or lived thru the horror of a construction project gone wrong. I won’t bury the lead any further. We love our ADU!!!!! We started the project on Jan 31st of 2024. We were told that the project would take 6-8 months. We lost the first 6 weeks or so with the heavy rains from last year, but even with that delay, we were mostly done with the project by the middle of August. We ran into the “expected” unknowns and surprises – all dealt with fairly and quickly by Micky and team. I would like to call out Joachin who was amazing. We always felt like we were in the best of qualified hands during this entire process. All inspections were signed off, the last checks were written, and we now have a gorgeous new home behind the main house on that property. We were so happy with the project and trusted Micky and Joachin so much, that we immediately launched a second project of gutting and renovating a very large master bathroom for my In-Laws. That job started on September 23rd and was done the first or second week of November as promised. It would’ve been done sooner, but we had a little “client indecision” that cost us about a week or two. All in all, I would highly recommend Micky and his crew, and we plan to use them for as long as they are in business or until my family and I run out of projects."

"Jorge, Andy and their team at A1-Builders were knowledgeable, honest, reliable and above all always available to answer any questions we had. They helped build a 2 bed 1 bath 600sqft addition to our home during the lean months over the pandemic. We had multiple projects (pool, patio, retaining wall) going on at the same time with other contractors and the crew from A1-Builders were by far the most professional. They always made sure that they left their work site clean after each dayâ s work. Jorge will definitely be the first person I call for our next home project because I know that even if he does not have the time to do the work, he will always guide me in the right direction.

FAQs for addition to existing structure building service projects in Rancho Cucamonga, CA

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
