Brownsville build questions.

How much does it cost to build a custom home in Brownsville?

It depends on plan, lot, and finish tier. For 2026, Sisu’s range is roughly $108 to $150 per square foot built in Cameron County, with Custom tier quoted per project. Get the RGV Custom Home Cost Guide for the full breakdown.

How long does it take to build a home in Brownsville?

From contract to closing, a typical Sisu custom home in Brownsville takes 22 to 32 weeks. Weather rarely slips the schedule by more than a week. The biggest variable is allowance items like cabinets and tile, where lead times can stretch.

Can you build on a lot I already own in Brownsville?

Yes. About half of our custom builds are on lots the client already owns. Bring us the survey and the soils report (if you have one) and we’ll price the build on your specific lot.

Do you build commercial in Brownsville?

Yes. Sisu is a Texas General Contractor and we take on commercial projects in Brownsville on a case by case basis. See our commercial page.

What’s the difference between Sisu and a production builder?

Production builders work from a fixed plan library and a fixed finish menu, in a fixed subdivision. Sisu builds custom: your plan, your lot, your finishes. The trade off is timeline and decision count. The benefit is a home built specifically for you, by the person who quoted it.
