Home Additions & ADUs in Lewisville, TX

Home Additions & ADUs in Lewisville

Much of Lewisville was built out as single-story living. The ranch homes of Lewisville Valley and the established subdivisions from the city's 1970s and '80s boom sit on generous, mature-tree lots — and plenty of those families have outgrown the original footprint without wanting to leave the neighborhood, the schools, or the shade. That's the classic setup for an addition: build out or up rather than pack up and move.

Additions for the way Lewisville lives

The most common request in these older neighborhoods is a primary-suite addition, a bumped-out or bumped-back kitchen, or a second living area grafted onto a single-story ranch that's simply short on room. Rear-entry-garage lots often leave usable backyard depth to work with. The craft is in making an addition look like it was always there — matching the brick, the roofline, and the window proportions of a 1975 home rather than bolting on something that announces itself from the curb. We confirm setbacks, easements, and lot coverage before design gets expensive, because those limits shape what the footprint can actually be.

ADUs and multi-generational space

Detached ADUs, garage conversions, and garage apartments are a growing ask in Lewisville — a place for an aging parent, an adult child, or a home office that isn't in the house. What a given lot allows depends on its zoning, size, and setbacks, and whether a separate utility connection is required, so the first job is always confirming what the city will approve on your specific parcel. We'd rather answer that honestly up front than design something that can't be permitted.

Permitting through MGO Connect

An addition or a detached ADU is real structural work — foundation, framing, and its own electrical, plumbing, and mechanical rough-ins, each pulled by the state-licensed trade doing it. Lewisville handles every bit of that through one channel: the city's Building Services division at 151 W. Church Street runs residential permitting through the MGO Connect (MyGovernmentOnline) portal, where the application, fees, permit tracking, and inspection requests all live. The city also requires the contractor to be registered in MGO Connect before it will issue a permit — we keep that registration current and file under our own MGO account, so the paperwork isn't your problem. If you'd like to follow along, you can create an MGO account and watch the inspections clear in real time.

Building it right

The Remo Guys is an insured and bonded design-build based in Allen, working throughout Lewisville and the wider metroplex. We build additions to match the house they're attached to rather than announcing themselves as an afterthought, and if you're weighing an ADU as multi-generational or rental space, we'll talk through the real construction cost and the permit path plainly before anyone commits.
