Home Additions & ADUs in Farmers Branch, TX

Farmers Branch is an inner-ring suburb that filled in decades ago, so for most owners the choice isn't move or stay put — it's add the space the 1950s–70s ranch never had. A primary suite the original plan skipped, a bumped-out kitchen, a second living area, or a detached unit in the backyard: an addition keeps you on your lot, near the parks, the DART Green Line, and the I-35E/Tollway commute, instead of restarting somewhere new.

Additions for a mid-century ranch

The common ask across Valwood Park, Kensington Place, and the older streets toward Marsh Lane is a real primary-suite addition — bedroom, bath, and closet built onto a single-story that was drawn without one — or a rear bump-out that finally opens the kitchen to the living space. On the larger Brookhaven lots there's room to add square footage or a second story without crowding the setbacks. Matching a new addition to a sixty-year-old brick ranch so it reads as original, not bolted-on, is its own craft: brick blends, rooflines, and ceiling heights all have to carry across the seam.

ADUs, garage apartments, and rental potential

A detached ADU or a garage-apartment conversion can house an aging parent or a returning student — or a tenant, in a city where the Station Area's transit-oriented apartments and the job base in neighboring Addison keep renters plentiful. Farmers Branch zoning treats accessory dwellings by district and lot, so the first job is confirming what your specific parcel allows: size, setbacks, parking, and whether a separate utility connection is required. We'd rather answer that honestly up front than design something the city won't approve.

Permitting a new structure

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. All of it runs through the City of Farmers Branch Building Inspection Division at 13000 William Dodson Pkwy, filed on the Tyler EnerGov CSS portal (css.fbtx.net). The timing matters: since October 1, 2025 the city enforces the 2024 International Codes, including the 2024 IRC, and the 2023 National Electrical Code — a newer cycle than the 2018 I-Codes and 2020 NEC it previously used — so new construction has to be engineered and wired to the current editions from the first drawing. Getting that right at design saves a redraw at plan review.

Built to match, by one team

The Remo Guys is an Allen-based design-build that serves Farmers Branch, insured and bonded, and we build additions to match the house they attach to rather than announcing themselves as an afterthought. If you're weighing an ADU as a rental, we'll talk through the real construction cost and the permit path plainly before design gets expensive.
