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."

FAQs for second story addition building service projects in Rimforest, CA

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
