UnionMain Homes Buyer FAQ: Semi-Custom Changes, East-Side Communities and What to Check in DFW

​

UnionMain Homes is a homebuilder that builds across Dallas-Fort Worth and Atlanta, with most of its North Texas communities on the eastern and outer edges of the metroplex, in Celina, Melissa, Lavon, Fate, Royse City, Forney, Justin, Rhome and Waxahachie. It takes a semi-custom approach, letting buyers start from a base floor plan and make structural and finish decisions with a builder and sales counselor before construction. This page answers the questions buyers most often ask before buying a UnionMain home, including how far plans can change, what to confirm in its communities, and what to verify about a specific lot. It is written by an independent buyer's agent, not by the builder, and was updated in September 2026.

About the builder

Who is UnionMain Homes?

UnionMain Homes builds new construction homes in Dallas-Fort Worth and Atlanta, currently across roughly eighteen communities, and describes its leadership as bringing decades of combined homebuilding experience. It emphasizes a semi-custom process and amenity-focused communities, and its home types range from townhomes to larger single-family plans.

Where does UnionMain build in DFW?

Its DFW communities run from Celina and Melissa in the north to Waxahachie in the south, with Lavon, Royse City, Forney, Fate, Justin and Rhome in between. That places much of its activity east of US-75 and on the outer ring of the metroplex, where land costs less than in Frisco or Flower Mound and buyers typically get more square footage for the money, in exchange for a longer commute to central Dallas. Test that commute at the hour you would actually drive it before committing.

​

The semi-custom process

How much can I change a UnionMain floor plan?

UnionMain describes starting from a base floor plan and adding from there, with buyers choosing finishes such as cabinetry and trim and meeting with a builder and sales counselor to review options, blueprints and the homesite. Structural decisions have to be made early, before the foundation is poured, so ask which structural options are available on your plan and lot and get each one priced in writing before you sign.

Which decisions should I prioritize?

Spend first on what is expensive or impossible to change later: structural options, ceiling heights, window placement, electrical rough-in, plumbing locations and built-ins. Paint, fixtures, hardware and many finishes can be changed after closing. Set a total budget before the first design appointment.

How does the build process work?

The builder describes a sequence of choosing a plan, making selections, meeting with the builder and sales counselor to review options and blueprints, then construction with a walkthrough before handover. Ask at the start who your construction manager will be and how often you will receive updates, and keep every agreed change in writing as a signed change order.

What to verify in UnionMain communities

Do UnionMain communities have special districts?

Some do. Elevon, in the City of Lavon, where UnionMain builds, is a public improvement district, which means an assessment on top of city taxes for lots within it. Confirm special district status for the specific lot through the county appraisal district's taxing-unit list and the tax certificate before signing. The MUD versus PID explainer covers what each district means for the monthly payment.

Which school district serves these communities?

It depends on the address, and the answer is often not the nearest town's district. Communities in Lavon, including Elevon and Lake Breeze, are served by Community ISD, which also covers Copeville, Josephine and Nevada, and Elevon's assigned campuses sit in two different cities. In Celina, some communities are served by Prosper ISD rather than Celina ISD. Confirm the district and the specific campuses with the district before signing. The master-planned community guide covers these checks for many DFW communities.

Which county am I in?

UnionMain's DFW footprint spans several counties, including Collin, Rockwall, Kaufman, Denton, Wise and Ellis. The county determines which appraisal district values the home, where the homestead exemption is filed and which county tax rate applies, so confirm it for the specific lot.

Before your first visit

Do I need a real estate agent to buy a UnionMain home?

No, you can buy directly. The builder's sales counselors represent the builder. A buyer's agent is the one party working only for you, from contract review and lot and district verification through the financing comparison and the final walkthrough. On a semi-custom build, where more decisions are priced individually, having someone reviewing what is and is not in the written price matters more.

When should I involve my agent?

Before your first visit to a UnionMain model. Builders commonly have registration policies that tie agent recognition to the buyer's first visit, and a buyer who tours alone first may find an agent introduced later is not recognized.

Do I have to use the builder's preferred lender?

You are generally free to choose your own lender, though incentives are often conditioned on using a preferred lender. Compare total loan cost against independent quotes taken the same day. If a lender is affiliated with the builder, you should receive a written disclosure of that affiliation.

​

​

Contract, inspection and warranty

Is the UnionMain purchase agreement the standard Texas contract?

Builders generally use their own purchase agreements, drafted by the builder's attorneys, rather than the standard Texas Real Estate Commission resale contract. Terms governing deposits, selection deadlines, change orders, completion timing, warranty administration and dispute resolution are set by the builder's document. Read it before signing and have it reviewed. The builder contracts guide covers the categories that matter most.

Should I get an independent inspection?

Yes. Municipal inspections check code compliance, which is not the same as an independent inspection on your behalf. On a home built to your selections, the most useful stages are pre-drywall, when framing, plumbing and electrical are visible, and before the final walkthrough, with a further inspection shortly before the first-year workmanship coverage ends.

What does the warranty cover?

Coverage, exclusions and claim procedures are set by the warranty document in your contract, and structural terms in particular vary between builders. Ask how long structural coverage lasts and what it covers, read the document before signing, calendar the deadlines and submit requests in writing.
