Expert ADU Design & Planning in Metro Phoenix & Maricopa County

ADU design and planning in Chandler starts with knowing what your lot can support. R&M Construction and Development walks Chandler homeowners through every step, from site evaluation to construction-ready drawings. We review your lot size, zoning district, and setback requirements before a single line is drawn. Chandler's code ties ADU size directly to lot area. Detached units on lots up to 10,000 square feet are capped at 1,000 square feet. Exterior design must match the primary home or meet the city's stucco and concrete tile roof standard. Getting these details right in the design phase prevents costly revisions later. Whether you want a backyard casita for a family member, a rental unit, or a private guest suite, our team builds a plan that fits Chandler's current rules. Call R&M Construction and Development to schedule your ADU design consultation in Chandler today.

ADU Design & Planning FAQ

Common questions about adu design & planning in Metro Phoenix & Maricopa County.

Yes, Chandler allows one detached ADU by right on any single-family lot under Arizona HB 2720 and Ordinance 5113. R&M Construction and Development can review your Chandler lot to confirm eligibility before design begins.

On lots up to 10,000 square feet in Chandler, a detached ADU is capped at 1,000 square feet. Larger lots may allow more square footage depending on how the unit is classified, so confirming your category with Chandler Development Services is a key first step.

Yes, Chandler requires ADU exteriors to either match the primary residence's materials and style or use stucco walls with a concrete tile roof. R&M Construction and Development factors this into the design phase so your Chandler casita meets city standards from the start.

No, Chandler requires ADUs to share the primary home's water, sewer, and electric service rather than have separate meters. Our design process includes a review of your existing panel capacity to plan for this connection.

Yes, Chandler does not require owner-occupancy, so you can rent the ADU without living in the primary home. This makes ADU planning in Chandler a practical option for homeowners looking to generate rental income.

Our process covers site evaluation, lot and setback review, ADU type classification, and construction-ready drawings that align with Chandler's current code. We handle the planning details so your project moves into the build phase without surprises.

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.
