Expert ADU Permitting & Construction in Metro Phoenix & Maricopa County

Adding a casita or accessory dwelling unit to your Chandler property is one of the most practical ways to use your lot. R&M Construction and Development manages the full process: site evaluation, engineered plans, city permit submittal, and construction through final inspection. Chandler's updated zoning code, shaped by Arizona HB 2720 and Ordinance 5113, now allows one attached and one detached ADU by right on single-family lots. Detached units are capped at 1,000 square feet on lots under 10,000 square feet, with five-foot rear and side setbacks required. Many Chandler subdivisions also sit within HOA-governed communities, which may have their own architectural review steps separate from city approval. Getting HOA sign-off before city submittal keeps your project on track. Whether you need space for a family member, a home office, or a rental unit, R&M Construction and Development handles the permitting details and builds to Chandler's current code standards. Call us to review your lot and get started.

R&M Construction and Development did an excellent job painting the exterior of my home. From the beginning, they were transparent about the work that needed to be completed to ensure the best possible results. They were also very accommodating with last-minute changes and provided helpful recommendations throughout the decision-making process. The project was completed ahead of schedule, and I was able to see noticeable progress every day. Overall, I highly recommend R&M Construction and Development for any home improvement project.

Had the best experience with R&M Construction and Development. We redid all of the flooring, full interior paint and remodeled 2 bathrooms with them. The work they did came out amazing. They were very professional. We were not living at the home when the work was done but we went frequently to check on it and every time we went the home was always cleaned up by the time they left. Their team whole very helpful. They helped us with painting samples and explained the different paints. I'm in love with how everything turned out. I would highly recommend them.

R&M Construction and Development did an outstanding job building my spec home in Tonopah, Arizona. From start to finish, their team was professional, organized, and easy to work with. Communication was clear throughout the entire process, and they kept everything moving on schedule while maintaining high-quality workmanship. Their attention to detail really stood out from the finishes to the overall build quality, everything was done right the first time. They were transparent with costs, handled challenges quickly, and made the whole experience smooth and stress-free. If you’re looking for a reliable builder who takes pride in their work and delivers exactly what they promise, I highly recommend Ramiro. I’m excited to keep working with him on the second spec later this year. Jose Romero

I am very happy with the final result of my bathroom remodel by R&M Construction & Development. They have a great team! They communicated with me consistently through out the whole project, answered every question or concern I had immediately (day or night), explained everything in great detail, and reassured me regularly. I trust them completely and will use them when I have another project. I highly recommend them to friends & family,

I remodeled my whole home with R&M and his team. From floors, paint, kitchen, bathrooms, underground plumbing, patio and a few other projects and I cant say enough about them. The team is very competent! They communicate with you throughout the whole project and the quality is top notch. If you’re looking for quality and a great experience overall, this is your contractor.
