Room Additions & Extensions Experts

Room additions and extensions involve building new living space onto your existing home — whether that's an extra bedroom, a larger living area, a sunroom, a home office, or a full second-story addition. Maya Construction designs and builds room additions for Orange County homeowners from the ground up, handling everything from foundation work and framing to electrical, plumbing, drywall, painting, and final finish work. The result is a seamlessly integrated addition that looks and functions like it was always part of your home — because our team knows how to match existing materials, rooflines, and architectural details.



Room additions become necessary when your family has outgrown your current home but you love your neighborhood and don't want to move. They're also a smart investment when you need dedicated space for a home office, a guest suite, or an in-law unit, and when moving to a larger home would cost far more than expanding the one you already have. Many Orange County homeowners also explore room additions as an alternative to ADUs (Accessory Dwelling Units) for multigenerational living or rental income potential. If your home feels cramped but your lot has room to grow, an addition from Maya Construction may be the best investment you can make.

Room additions require architectural plans, city permits, foundation work, framing, MEP (mechanical, electrical, plumbing) rough-in, inspections at multiple stages, and final finish work — all coordinated by a licensed general contractor. Maya Construction manages every phase of your room addition project, from the initial design consultation and permit application through final city inspection and punch-list completion. We have extensive experience navigating Orange County's building departments and know what's required to get your project approved and completed without costly delays or rework.

"Mo replaced my 10-year-old water heater in under two hours, while another contractor previously took over four hours. He was incredibly efficient and responded to my call incredibly fast. Highly recommend him to anyone needing a water heater replacement."
"Mostafa's work and service were excellent. He was very responsive, accommodating, friendly, helpful, and knowledgeable. He arrived on time and completed the job quickly and efficiently. The quality of his work exceeded my expectations. I would definitely hire him again!"
"Mostafa did a great job with our bath vanity installation. The side splash we bought was the wrong size, but he took time to make a custom cut and tried different options — now it looks like it came with the vanity itself! Excellent quality of work and a true professional. Five stars!"
"I want to give a huge shoutout to Mostafa for coming to my rescue when my main contractor left me in a tough spot. I found him on a Sunday and within an hour we agreed on an appointment. He saved my project. Could not have asked for a better experience!"
"Mostafa was fantastic. Helped us install an outdoor shower and pergola. He worked within our budget and went above and beyond to make sure we were satisfied and got exactly what we were hoping for. Will hire again!"
