Plenty of Forney families are in the house they want and simply out of room. Between settled Forney ISD school zones and today's rates, moving rarely pencils out — so the question becomes how to add square footage that reads as if it were always there. A room addition, a second story, or an accessory suite: which one fits depends on your lot, your HOA, and how the new space ties into a house on North Texas clay. We serve Forney from our Allen studio about 35 miles west, so the honest first step is a visit to your actual lot.
The ADU question, answered honestly for Forney
If you've read about California backyard cottages or a "granny flat" ordinance, hold that loosely here. Whether a fully detached, independently rentable accessory dwelling is allowed on your single-family lot is a zoning question — one to confirm against current City of Forney code, not assume from headlines. What's reliably available are the attached paths: a bump-out or full room addition, a second story, or an in-law suite under the main roof. We confirm your zoning and deed restrictions first, then design to what your lot permits.
Build out or build up, and tie into the clay
Building out at grade is cheaper per square foot, but it spends lot coverage and leans on your setbacks. Forney's neighborhoods vary widely: the larger lots in established Windmill Farms, Diamond Creek, or Fox Hollow — and the genuine acreage on the county's rural edges toward Talty and Terrell — may have room to push out, while the tighter master-planned lots in Gateway Parks or Clements Ranch often make building up the smarter move. Either way the connection is structural. An addition marries a new slab to one settled on Blackland Prairie clay for years, so it must be engineered and doweled into the original, and a second story needs an engineer to confirm the existing structure can carry the load.
Permits, registration, and the HOA
Any change to square footage needs a building permit — including enclosing a patio or converting a garage. In Forney every contractor must first register through the city's MyGov portal (public.mygov.us/tx_forney) before a permit can be issued; the state-licensed trades pull their own permits for plumbing, electrical, and HVAC, so those registrations get confirmed before we apply. Layer the HOA's architectural review on top in Devonshire, Gateway Parks, and Clements Ranch, and you have two tracks to sequence before framing.
One team owns the seam
The whole promise of an addition is that it looks like it was always there — a coordination problem, not a single trade's task. Foundation tie-in, framing, roofline marriage, brick-and-mortar match, and drainage all have to meet at one seam and disappear. Matching brick to a wall weathered for years, and sequencing the engineer and trades under one plan, is what a general contractor exists to own. The Remo Guys adds onto homes across Forney from our Allen base — insured and bonded, since 2019 — treating the join between old and new as the whole job.

Home Additions & ADUs in Forney — FAQ
- Do I need a permit for home additions & ADUs in Forney, TX?
- Yes — home additions & ADUs in Forney is permitted work. It's filed through City of Forney Building Inspections Division (101 E. Main St) using MyGov online portal (public.mygov.us/tx_forney). Contractors must register through the MyGov portal before any permit is issued — general, electrical, mechanical, and plumbing contractors register at no charge, while only irrigation contractors pay a $30 fee; inspection requests go to a separate voicemail line (972-564-7380). We pull the permit and carry the project through every inspection.
- What does home additions & ADUs in Forney include?
- A home additions & ADUs project with us covers build-out (ground level) & build-up (second story); accessory dwelling units & in-law suites; foundation & drainage tie-ins on expansive clay; structural engineering & stamped plans; MEP extension & load checks; permits, setbacks & HOA review. Because we're design-build, one team owns design, engineering for North Texas's expansive clay soil, Forney's permitting, and construction — so nothing falls between a separate designer, builder, and stack of subcontractors.
- How much does home additions & ADUs cost in Forney?
- It depends on the size of the project, the finishes, and any structural or foundation work, so we scope and price each Forney project individually rather than quote a flat rate. To plan around typical DFW ranges, use our cost estimator or the free remodel cost & permit guide.
- Is The Remo Guys licensed and insured?
- Texas doesn't issue a statewide license for residential general contractors, so the real assurance is one accountable team that's insured and bonded — which The Remo Guys has been since 2019. The state-licensed electrical, plumbing, and HVAC trades on your project each pull and inspect their own permits under the build.
