Corpus Christi Site Plan for Permit: When You Need One

Planning a new home, room addition, garage, shed, deck, patio cover, swimming pool or driveway project in Corpus Christi? A site plan may be one of the main drawings required with your permit application.

A site plan gives permit and zoning reviewers a top-down view of the property. It shows what is already on the lot, what you want to build and how the proposed work relates to property lines, streets, easements and required setbacks.

Projects that commonly require a site plan

When a site plan may not be necessary

Not every home project changes the site. For example, Corpus Christi’s current guidance for an interior remodel generally lists a floor plan, scope of work and any required engineered repair information rather than a site plan.^[2]

A site plan may not normally be needed when the work is completely inside the existing building and does not change:

• The exterior building footprint
• The location of doors, stairs or exterior landings
• The driveway or access from the street
• The position of accessory structures
• Grading, drainage or floodplain conditions
• Utilities or construction within the public right-of-way

What should a Corpus Christi site plan show?

A clear site plan should allow reviewers to understand the complete property layout without relying on a rough sketch or verbal explanation.

Site plan versus property survey

A site plan and a property survey are related, but they are not the same document.

Corpus Christi describes a plat as a map showing the important features of a subdivision and explains that the final plat is recorded with the appropriate county clerk. A recorded plat can provide useful lot and easement information, but it does not necessarily show the current house or other improvements.^[8]

A permit site plan can often use an available survey, recorded plat and other reliable property records as references. When boundaries are uncertain or a project is very close to a setback, a licensed land surveyor may be needed.

Why setbacks matter

A setback is the required separation between a building or structure and a property line, street or other regulated feature. Setbacks help determine the part of the lot where construction may be permitted.

Corpus Christi’s Unified Development Code establishes development standards for properties within the city and its extraterritorial jurisdiction. The UDC is updated over time, so homeowners should confirm the current zoning district and standards for their address.^[4]

Do not copy setback measurements from another property. Requirements can vary because of:

• The zoning district
• The type and size of structure
• Front, side and rear lot conditions
• Corner-lot street frontage
• Utility or drainage easements
• Recorded plats or special approvals
• Floodplain or coastal-development requirements

New homes and additions

Corpus Christi’s new-residential-building guidance says a complete submission for a new home or addition includes a site plan, floor plan, engineered foundation plan, exterior elevations, roof plan, building section, energy documentation and windstorm information.^[1]

On the site plan, the proposed home or addition should be clearly separated from existing construction. Include its complete outside dimensions and distances from the nearest property lines.

An elevation certificate may also be required when the property is within a floodplain. The City recommends contacting Development Services for current FEMA information when the flood status is uncertain.

Garages, sheds, decks and patio covers

Corpus Christi groups garages, carports, storage buildings, porches, gazebos, patio covers, decks and docks under accessory construction and remodeling. The City’s current submission list includes a site plan, existing-and-proposed floor plans, a foundation plan and windstorm documentation.^[2]

The site plan should show the entire project footprint, including stairs, landings, roofed areas and structural projections that may extend beyond the main walls or deck platform.

Useful information for an accessory project

• The overall width and length
• The distance to each nearby lot line
• The distance between the project and the house
• Existing garages, sheds, decks or pools
• The driveway or access route
• Known easements and drainage areas
• The foundation, slab or footing location

Pools and spas

Swimming pools and spas are included in the City’s accessory construction and remodeling guidance. A complete application may involve a site plan, foundation information, windstorm documents and any necessary electrical or plumbing permits.^[2]

A pool site plan should normally show the pool shell, surrounding deck, existing house, equipment location, property boundaries and distances to the relevant lot lines.

Driveways, sidewalks and the public right-of-way

Corpus Christi lists an existing-and-proposed site plan for driveway and sidewalk permit work located within the public right-of-way.^[2]

The public right-of-way includes streets, sidewalks and areas behind the curb extending toward the property lines. The City’s Public Works Department regulates construction and other activities within this area.^[6]

A driveway site plan may need to show:

• The existing and proposed driveway
• Driveway width and pavement limits
• The street and curb connection
• Sidewalk crossings
• Property boundaries
• Nearby utilities or drainage features

Floodplain and coastal considerations

Corpus Christi’s development guidance emphasizes that development must comply with applicable permits and floodplain rules. Properties within mapped flood areas may require elevation information or additional review.^[5]

The City also notes that beachfront construction may require a Beachfront Construction Certificate or, for certain Kleberg County projects, a Dune Protection Permit.^[1][2]

How the permit process generally works

1. Define the project.
   Record what you plan to build, its proposed dimensions and the preferred location.
2. Check the property zoning.
   Confirm the zoning district and the placement standards that apply to the project.
3. Gather property documents.
   Locate an available survey, recorded plat, legal description or previous permit drawing.
4. Prepare the site plan.
   Show the property boundaries, existing structures, proposed work, dimensions, setbacks and easements.
5. Prepare construction documents.
   Add the floor plans, foundation plans, elevations, structural details and windstorm information required for the project.
6. Submit through the Dynamic Portal.
   The City’s online portal allows users to apply for permits, upload documents, review comments, pay fees and view inspection results.^[3]
7. Respond to comments.
   Revise the plans when reviewers request clearer dimensions, additional documents or a different project location.
8. Obtain approval and schedule inspections.
   Begin permit-required work only after the permit is issued and complete the required inspections as construction progresses.

Common site-plan mistakes

• The proposed project is not clearly labeled.
• The property boundaries are missing.
• The project dimensions are incomplete.
• Distances to property lines are not shown.
• A fence is treated as the confirmed legal boundary.
• Existing garages, sheds, decks or pools are omitted.
• Easements are not shown.
• The site plan and construction plans contain different dimensions.
• The driveway or public right-of-way is not identified.
• Floodplain or windstorm documents are missing.

Can an aerial-based site plan be used?

An aerial-based site plan can provide a clear, easy-to-read layout for many residential projects. It can show the house, driveway, yard, existing structures and proposed construction in one drawing.

However, aerial imagery does not legally establish property boundaries. When exact boundary information is necessary, use an existing survey or consult a Texas licensed land surveyor.
