Local Intelligence
What Corpus Christi Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Corpus Christi — Development Services Department will not accept a permit application without them. Corpus Christi's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Corpus Christi currently requires owner-occupancy on the primary parcel — meaning one of the units (the main home or the ADU/conversion) must be your primary residence.
Homeowners in Corpus Christi who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $993/month.
Permit Process & Fees
Development Services Department permit fees for this project type typically range from $864 to $2,712 depending on project valuation and scope. Plan check runs approximately 6 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Development Services Department as part of a permit application must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus if structural changes are involved, a licensed engineer must stamp the structural drawings.
Visit Development Services Department ↗Construction Cost Context
Corpus Christi's adu / renovation construction costs run $210–$350 per square foot — a wide range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.
⚠ Common Pitfall in Corpus Christi
Since most of Corpus Christi's older neighborhoods sit within the Coastal Management Zone, your ADU plans will need a Coastal Development Permit from the city on top of the standard building permit — this alone can tack on 4-6 weeks because it routes through a separate review tied to the Texas General Land Office's coastal boundary rules. Add to that the fact that many lots east of Ocean Drive and near the bayfront have older clay or cast-iron sewer laterals that the Development Services Department will require you to camera-inspect before approving a new sewer tap, and homeowners often get blindsided by a $2,000-$5,000 repair bill they didn't budget for. Because Nueces County flood maps got redrawn after Hurricane Harvey, you'll also want to double check your elevation certificate before finalizing ADU foundation height, since some parcels quietly shifted flood zones and now require raised slab construction that wasn't needed even five years ago.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 6-week timeline and $300/sqft figure are Corpus Christi state-level estimates, not gospel — I'd get a couple of local contractor quotes and call the Development Services Department directly before penciling in a schedule, especially since your parcel's coastal overlay means the CDP review alone can tack on several additional weeks that a clean plan check timeline doesn't account for."

Common Questions
Corpus Christi Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Corpus Christi? +
You need accurate floor plans for: permit applications (required by Corpus Christi's building department for any structural work), refinancing or home equity loans, selling your home (accurate square footage documentation), renovation contractor bidding, HOA design review submissions, and insurance claims. Our as-built drawings capture your home's exact current dimensions.
What is an as-built floor plan and why do I need one in Corpus Christi? +
An as-built floor plan documents your home as it currently exists — including all room dimensions, door and window locations, wall thicknesses, and square footage. These are required when the original permit drawings are unavailable or the home was modified without permits. Corpus Christi's building department requires accurate as-builts when you apply for renovation or addition permits on older homes.
How much does floor plan drafting cost in Corpus Christi? +
Our floor plan drafting packages for Corpus Christi start at $997 for a standard residential home. This includes measured floor plans for all levels, room labels, door and window schedules, and verified square footage. Local drafting services typically charge $1,500–$4,000 for the same work. We deliver within 10 business days with a 14-day money-back guarantee.
How do you create floor plans remotely for my Corpus Christi home? +
You provide basic measurements (room dimensions, door/window sizes) and photos of each room. Our drafting team converts these into accurate CAD drawings with precise dimensions, wall thicknesses, and notations. For permit-grade as-built drawings, we may request additional measurements or a site visit from a local partner. We serve all Corpus Christi neighborhoods remotely.
What format are the floor plan drawings delivered in? +
We deliver drawings in PDF (for printing and permit submission) and DWG/DXF (AutoCAD-compatible format for contractors, engineers, and architects to work from). All drawings are formatted to Corpus Christi building department standards and include title block, scale, and code notations required for permit submission.
Can you draft floor plans for a rental property or multi-unit building in Corpus Christi? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Corpus Christi. Multi-unit buildings are priced based on the total number of units and floors. Contact us for a custom quote if your property has more than 4 units.
Will accurate floor plans increase my home's value in Corpus Christi? +
In Corpus Christi, where median home values are around $185,000, inaccurate or missing square footage records can suppress list price and appraisal value. Professional as-built drawings establish defensible square footage for appraisers and buyers. Unpermitted additions documented and legitimized through permit drawings can recover thousands in appraised value.
Do I need floor plans to get an ADU or addition permit in Corpus Christi? +
Yes — Corpus Christi's building department requires accurate floor plans as part of any ADU, garage conversion, or addition permit application. Our packages combine floor plan drafting with the full permit-ready drawing set (site plan, elevations, electrical, Title 24) needed for plan check submittal. If you only need the floor plans themselves, our Starter package covers that.
Can you draft floor plans from old blueprints or photos in Corpus Christi? +
Yes — we can redraft from original blueprints, scans of old permit sets, hand-drawn sketches, or room photos combined with your measurements. We regularize old drawings to current CAD standards and update them to reflect any modifications made since original construction. This is a common service for Corpus Christi homes built before the 1990s.
