House Plans and Custom Drafting in Corpus Christi, TX
Service Areas › Texas › Corpus Christi
In Corpus Christi, every new home, addition, or major alteration must be engineered to Texas Department of Insurance windstorm specifications and earn a WPI-8 certificate before it qualifies for TWIA wind insurance. That single requirement changes what a plan set has to be here: drawings for the Coastal Bend are held to a stricter standard than drawings for inland Texas, and a set that ignores that costs you time at the permit counter and leverage with your insurer. Apex Drafting Services produces residential drafting for Corpus Christi projects with that standard in view from the first line.

Plan Sets Built for a TWIA County
Nueces County is one of 14 coastal counties designated by the Texas Windstorm Insurance Association. Inside that zone, windstorm compliance is not an upgrade, it is the entry ticket: new construction, additions, and even re-roofs must be built to TDI windstorm specifications and certified with a WPI-8 Certificate of Compliance to qualify for TWIA wind and hail coverage. For a homeowner, that certificate is often the difference between insurable and uninsurable.
To be clear about roles: we are your drafting team, not your engineer of record or your inspector. Windstorm engineering and the certification itself run through those professionals. Our job is to deliver a plan set with the structural detailing, connection callouts, and documentation they need, so the certification process moves instead of stalling on incomplete drawings. That is the standard we draft to for every Corpus Christi project.
Corpus Christi's Building Market, by the Numbers
The permit series tells a story of consistency: Nueces County was authorized 1,496 new private housing units by building permits in 2025, compared with 1,645 in 2024 and a 2021 peak of 1,950 (U.S. Census Bureau Building Permits Survey). Call it a steady pipeline of roughly 1,500 units a year. The city's population is essentially flat, down 0.3% from the 2020 Census count of 318,278, while the metro area sits near 358,000 and grew 0.85% year over year (Macrotrends). This is a stable coastal market, not a boomtown, and the drafting work reflects that: a dependable flow of new builds alongside owners improving the homes they already have.
The local plan-drawing scene is moderate rather than crowded: a longstanding local drafting firm, a national drafting site with a Corpus Christi page, and design-build builders who keep plan work in-house for their own projects. No dominant standalone residential drafting brand surfaced in our research. If you are not building inside a design-build package, you still need a complete, windstorm-detailed plan set from somewhere, and that is the gap an independent drafting studio fills.
ADU Rules in Corpus Christi and Texas
Texas has no statewide ADU mandate, so accessory dwelling units are regulated entirely city by city. SB 673, a 2025 bill that would have preempted local ADU restrictions statewide, passed the Senate but died in the House on June 2, 2025. The result is a patchwork: Austin's HOME Initiative is the most permissive, with more than 1,200 ADU permits issued in two years, a 340% increase; Dallas is the most restrictive, requiring an ADU Overlay District; Houston has no zoning code at all, so deed restrictions govern; and San Antonio allows ADUs by right with an owner-occupancy affidavit.
For Corpus Christi specifically, our research did not surface a city-specific ADU ordinance. The city's Unified Development Code governs and is currently being updated, per the city's website, so confirm current requirements with the city's development services before you commit to a design. One thing we can say with confidence: a backyard unit here is new construction, which means it carries the same TDI windstorm-specification requirements as a new house. Our ADU plans and design service is built to handle both sides of that, the layout you want and the coastal detailing the county demands.
The Services Corpus Christi Projects Ask For
All eight of our services are available here, but four of them map directly onto what the local data shows.
Permit-Ready Drawings & As-Builts
In a county where insurance eligibility hangs on a WPI-8 certificate, documentation is everything. We produce complete permit-ready sets, and as-built drawings for existing coastal homes that need accurate records before a remodel or certification effort.
Home Additions & Remodel Drafting
With the typical home value at $218,988 and prices up just 0.2% in a year, adding space often makes more sense than trading up. Additions and major alterations in Nueces County must meet the same windstorm specs as new builds, so the drawings have to be right the first time.
Custom House Plans
Roughly 1,500 new housing units are permitted countywide each year. If yours is one of them, a custom plan designed to TDI windstorm specifications from day one beats retrofitting compliance into a design that never considered it.
Stock House Plans
Starting at $799, stock plans are the budget-friendly entry point. For a Corpus Christi lot, we can review and adapt a stock design so its detailing lines up with the windstorm requirements your site will face.
Many clients also pair their plan set with 3D renderings and walkthroughs to review the design before permitting, and coastal clients frequently ask about energy-efficient home design alongside the structural work.
How Remote Drafting Works for Coastal Bend Projects
Apex Drafting Services works fully remotely from Colorado City, Arizona. There is no Corpus Christi office and we will not pretend otherwise: plans are drafted, revised, and delivered digitally, and your builder, engineer, and inspector handle the on-the-ground steps they were always going to handle.

Corpus Christi Drafting FAQs
Do house plans in Corpus Christi have to meet windstorm requirements?
Yes. Nueces County is one of 14 TWIA-designated coastal counties, so new homes, additions, and re-roofs must be built to Texas Department of Insurance windstorm specifications and certified with a WPI-8 Certificate of Compliance to qualify for TWIA wind and hail insurance. Plan sets should be detailed with that certification process in mind from the start.
Can I build an ADU in Corpus Christi?
Texas has no statewide ADU mandate, so rules are set city by city. Our research did not surface a Corpus Christi-specific ADU ordinance; the city's Unified Development Code governs and is currently being updated. Confirm current requirements with the city's development services before you design, and remember that a new backyard unit in Nueces County carries the same windstorm-specification requirements as any new construction.
How much do house plans cost in Corpus Christi?
Stock house plans start at $799. Custom house plans, additions, ADUs, and as-builts are priced by scope, so the honest answer is that it depends on your project. Request a free quote and we will give you a firm number for your specific build.
Is Corpus Christi a good market to build in right now?
The data points to a steady market rather than a boom. Nueces County was authorized 1,496 new private housing units by building permits in 2025, versus 1,645 in 2024 and a 2021 peak of 1,950 (U.S. Census Bureau). Zillow puts the typical Corpus Christi home value at $218,988, up 0.2% over the past year, with homes going pending in about 16 days. That means a consistent construction pipeline without boomtown volatility.
