How to Get a Plot Plan in Texas for a Building Permit

A plot plan—also commonly called a site plan—is an overhead drawing showing how buildings and exterior improvements fit within a property.

A residential permit reviewer may use the drawing to understand:

• Which property is being developed
• What buildings and improvements already exist
• What work is proposed
• The project’s size and intended location
• Distances to property boundaries
• Distances between existing and proposed structures
• Whether building lines or easements affect the project
• How the property connects to a street or alley
• Whether drainage, floodplain, septic, tree, or utility review applies
• Whether the plot plan agrees with the other permit drawings

A clear plot plan cannot guarantee permit approval. It provides measurable property and project information for review under the rules applying to that jurisdiction and property.

What Is a Texas Plot Plan?

A Texas plot plan is a scaled or fully dimensioned drawing of a property as viewed from above.

It commonly identifies:

• Property address
• Lot, block, subdivision, or parcel information
• Complete property boundaries
• Available lot dimensions
• Existing house or principal building
• Garages, carports, sheds, and accessory structures
• Decks, patios, pools, and exterior improvements
• Driveways, parking areas, and walkways
• Proposed construction
• Project length and width
• Distances to property lines
• Distances between structures
• Recorded easements
• Platted or recorded building lines
• Adjoining streets and alleys
• North arrow and drawing scale

Additional information may be required for properties involving:

• Floodplains
• Private wells or septic systems
• Sloping land
• Drainage changes
• Protected trees
• Public right-of-way work
• Historic or conservation districts
• Utility or pipeline easements

A plot plan is different from a floor plan.

A floor plan shows rooms, walls, doors, and interior spaces. A plot plan shows where the building and exterior improvements sit within the property.

Texas Does Not Use One Local Permit System

Texas homeowners do not submit every residential project through one statewide building-permit portal.

Permit applications and plot-plan requirements are administered by the authority responsible for the property and project.

That authority may be:

• An incorporated city
• A county office
• A floodplain administrator
• A public works or transportation department
• An onsite-sewage or environmental authority
• A utility or special district
• More than one participating agency

Austin, Dallas, Houston, and San Antonio each publish separate residential applications, checklists, and submission procedures.

A drawing accepted for a project in one Texas city should not automatically be assumed sufficient for another.

City Limits, ETJs, and Unincorporated Properties

Before ordering or drawing a plot plan, determine whether the property is:

• Inside incorporated city limits
• Within a city’s extraterritorial jurisdiction, commonly called an ETJ
• In an unincorporated county area
• Inside another municipality
• Within a special district or utility service area

Do not assume that an ETJ automatically follows the same building-permit process as property inside city limits.

An ETJ can affect matters such as:

• Subdivision or platting review
• Development agreements
• Utility service
• Roadway access
• Floodplain administration

The specific authority depends on the location and project.

For an unincorporated property, separate reviews can still apply to:

• Floodplain development
• Onsite sewage facilities
• Driveways connecting to county or state roads
• Subdivision or platting
• Water and utility service
• Special districts
• Deed restrictions

Confirm the requirements directly with the city, county, and other agencies responsible for the property.

Where to Get a Plot Plan in Texas

There are several ways to obtain the base property information needed for a residential plot plan.

1. Look for the survey from your home purchase

Many Texas homeowners received a survey during the purchase or financing of their property.

Check:

• Closing documents
• Title-company records
• Mortgage or lender documents
• Property-owner files
• Documents supplied by the previous owner

An existing survey may show:

• Property boundaries
• Boundary dimensions
• Existing house
• Garage or accessory structures
• Driveway
• Easements
• Building lines
• Fences or other improvements

Review the survey carefully before using it.

An older survey may not show a later:

• Home addition
• Garage or carport
• Shed
• Pool
• Deck or patio
• Driveway extension
• Fence or retaining wall

The local permit authority may require a newer survey or additional property information depending on the project.

2. Obtain the recorded subdivision plat

A recorded subdivision plat can be especially useful when the property is identified by a lot and block within a named subdivision.

A plat may show:

• Lot number
• Block number
• Subdivision name
• Lot dimensions
• Street and alley layout
• Utility easements
• Drainage easements
• Building lines
• Other recorded notes

Recorded plats are commonly available from the county clerk, county records office, or local development department.

A subdivision plat usually does not show the complete current house footprint or every later improvement. It may need to be combined with a survey, previous plan, photographs, and field measurements.

3. Check previous permit records

A previous approved plot plan can provide useful property and building information.

Search for permit records relating to:

• Original home construction
• Previous additions
• Garages and carports
• Pools
• Accessory buildings
• Driveways
• Other exterior improvements

Verify that the previous plan still matches the property.

Do not reuse an old plan without checking:

• Current structures
• Current paving
• Recorded easements
• Property dimensions
• Drawing scale
• Legibility

4. Use appraisal-district records for research—not as a survey

A county appraisal district can help locate:

• Parcel identification
• Owner and tax information
• Approximate parcel shape
• Lot size
• Recorded deed references
• Approximate building outlines
• City or district information

These records can be useful during preliminary research.

They should not automatically be treated as professionally surveyed property boundaries.

Dallas Central Appraisal District states that its GIS products:

• Are provided for informational purposes
• May not be suitable for legal, engineering, or surveying purposes
• Do not represent an on-the-ground survey
• Show only the approximate relative location of property boundaries

Other Texas appraisal districts publish similar GIS limitations.

5. Hire a Texas land surveyor when certified property information is required

A Texas-registered professional land surveyor may be needed when:

• No reliable survey is available
• Property corners cannot be found
• The proposed work is close to a property line
• The lot has an irregular shape
• Available property documents conflict
• An easement location is uncertain
• Certified elevations are required
• The property is in a flood hazard area
• The permit checklist specifically requires a survey
• A boundary dispute exists

A drafter cannot independently locate or legally certify property boundaries.

6. Have the proposed work added to a reliable base plan

Once reliable property information is available, the proposed project can be added to the drawing.

Provide:

• Project length and width
• Proposed height when relevant
• Preferred location
• Measurements to property lines
• Measurements to existing structures
• Floor plans or manufacturer drawings
• Photographs
• A marked survey or hand sketch

The completed plot plan should clearly distinguish existing conditions from proposed construction.

Plot Plan vs Survey vs Construction Drawings

A residential permit application can require more than one of these documents.

For example, an addition application may require:

• Survey or survey-based plot plan
• Proposed site layout
• Foundation plan
• Floor plan
• Exterior elevations
• Framing plans
• Energy documents
• Structural engineering

What a Texas Permit Plot Plan Should Show

Property identification

Include:

• Complete property address
• Parcel or tax identification number when required
• Lot and block when available
• Subdivision name when available
• Project title
• Brief scope description
• Drawing or revision date

The property information should agree with the permit application and supporting records.

Complete property boundaries

Show:

• Front property line
• Left-side property line
• Right-side property line
• Rear property line
• Street-side boundary on a corner lot
• Curved, angled, or irregular segments
• Available boundary dimensions
• Adjoining streets and alleys

Do not automatically use a fence, hedge, retaining wall, pavement edge, or GIS line as the legal boundary.

Existing structures and improvements

Show relevant existing features, including:

• Main house
• Existing additions
• Attached and detached garages
• Carports
• Sheds and workshops
• Accessory dwellings
• Decks and porches
• Patios and walkways
• Swimming pools and spas
• Driveways and parking areas
• Retaining walls
• Fences and gates when relevant

An omitted improvement can affect setbacks, lot coverage, access, drainage, and building separation.

Proposed work

Clearly distinguish the proposed project from existing conditions.

Use:

• A clear “PROPOSED” label
• Different hatching
• A heavier outline
• A distinct line style
• An existing-and-proposed legend

Show the complete proposed footprint, including relevant:

• Exterior walls
• Foundation outline
• Supporting posts
• Deck or porch platforms
• Stairs and landings
• Roof or eave projections
• Pool or equipment pads
• New driveway or paving
• Structures proposed for removal

Project dimensions

Show the project’s overall length and width.

Irregular projects should include enough measurements to define the complete proposed shape.

The dimensions should agree with:

• Permit application
• Foundation plan
• Floor plans
• Exterior elevations
• Structural plans
• Manufacturer or contractor drawings

Actual distances to property lines

Show the shortest relevant distance from the proposed project to:

• Front property line
• Both side property lines
• Rear property line
• Street-side line on a corner lot
• Platted building line
• Known easement boundary

Do not expect the reviewer to calculate the distance using the drawing scale.

Texas setbacks vary by jurisdiction, zoning district, planned development, subdivision plat, project type, height, and property conditions.

Distance between structures

Show the distance between the proposed work and relevant existing buildings.

This can include separation from:

• Main house
• Detached garage
• Carport
• Shed
• Accessory dwelling
• Deck or porch
• Other structures

Building separation can affect fire resistance, zoning, access, and structure classification.

Easements and building lines

Show known:

• Utility easements
• Drainage easements
• Sanitary sewer easements
• Access easements
• Shared-driveway easements
• Pipeline easements
• Platted building lines
• Other recorded restrictions

A structure can satisfy a normal zoning setback and still conflict with an easement or recorded building line.

Easement information may be found on:

• Property survey
• Recorded plat
• Title documents
• Previous approved plans
• Recorded easement instrument

Driveways, streets, and access

Show relevant:

• Adjoining street name
• Public alley
• Existing and proposed driveway
• Parking area
• Garage entrance
• Public sidewalk
• Curb or roadside ditch
• Pedestrian walkway
• Vehicle and pedestrian gates

Construction within a public right-of-way may require a separate driveway, public works, or transportation permit.

Utilities, septic systems, and wells

Project-specific utility information may include:

• Water line and meter
• Sanitary sewer
• Sewer cleanout
• Gas service
• Electrical service
• Overhead utility lines
• Septic tank
• Drain field
• Private well
• Stormwater facilities

Properties using a private well or onsite sewage system may require separate review before the building permit can proceed.

Drainage, grading, and floodplain information

Additional information may be required when the project:

• Changes existing grades
• Adds substantial roof or paving
• Uses fill
• Includes a retaining wall
• Affects a drainage easement
• Redirects surface runoff
• Is located in a flood hazard area

The permit package may require:

• Existing and proposed elevations
• Contour lines
• Drainage arrows
• Cut-and-fill information
• Finished-floor elevation
• Swales
• Floodplain boundaries
• Elevation certificates
• Engineering calculations

A standard drafted plot plan does not replace civil, drainage, floodplain, or geotechnical engineering when professional design is required.

North arrow, scale, and labels

Include:

• North arrow
• Written drawing scale
• Graphic scale bar when useful
• Readable dimensions
• Clearly identified measurement units
• Existing and proposed labels
• A legend for line types and symbols

How to Get a Texas Plot Plan Step by Step

Can You Draw a Texas Plot Plan Yourself?

Some Texas jurisdictions allow homeowners, contractors, or other responsible parties to prepare plot plans for certain residential projects.

Acceptance depends on:

• Project type
• Property conditions
• Permit checklist
• Quality of the property records
• Distance from construction to property lines
• Whether certified information is required

A do-it-yourself plot plan should still be:

• Accurate
• Scaled or fully dimensioned
• Readable
• Complete
• Consistent with the remaining drawings

Common DIY problems include:

• Showing only part of the property
• Using an online parcel line as a surveyed boundary
• Omitting existing structures
• Failing to dimension the proposed work
• Leaving out property-line distances
• Ignoring easements or building lines
• Using different project dimensions on different drawings

A homeowner-prepared drawing cannot replace a licensed survey, structural engineering, drainage design, or professionally sealed plan when one is required.

How Our Texas Plot Plan Drafting Service Works

1. Place your order. Select the site-plan option matching the requested level of detail.
2. Provide the property address. Confirm the city, county, or other reviewing authority.
3. Upload property documents. Send the survey, recorded plat, previous plan, or permit comments.
4. Describe the proposed project. Include its dimensions, height, use, and basic scope.
5. Mark the intended location. Send a marked survey, sketch, photographs, or construction drawing.
6. Review the completed draft. Check the project location, dimensions, labels, and property relationships.
7. Confirm the complete application. Obtain any separate survey, architecture, engineering, floodplain, or trade documents required locally.

The usefulness and accuracy of the completed plot plan depend on the surveys, plats, measurements, photographs, and project information supplied.

USA Site Plans provides drafting services. Standard drawings are not signed or sealed by a Texas-registered professional land surveyor, architect, or engineer.

Common Reasons Texas Plot Plans Receive Corrections

• The wrong reviewing jurisdiction is used
• An outdated permit checklist is followed
• Only the immediate project area is shown
• Property boundaries are missing or uncertain
• A fence or GIS line is treated as the legal boundary
• Lot dimensions are incomplete
• An existing garage, shed, deck, or pool is omitted
• The proposed project is not clearly labeled
• Project dimensions are missing
• Property-line distances are unclear
• Distance between buildings is omitted
• A platted building line is missing
• An easement is not shown
• The driveway or alley is omitted
• Private well or septic information is missing
• Drainage or floodplain conditions are overlooked
• The plot plan conflicts with the floor plans
• The drawing is cropped, blurry, or unreadable
• A drafted plan is submitted where a survey is required
• Required engineering or construction drawings are missing

A complete drawing cannot eliminate every review comment, but it can avoid corrections caused solely by missing, unclear, or inconsistent plot-plan information.

Frequently Asked Questions

Where can I get a plot plan for my Texas property?

Start with the property survey from closing, a recorded subdivision plat, or a previous approved permit plan. Appraisal-district records can support research but should not automatically be treated as a boundary survey.

Does Texas have one statewide plot-plan requirement?

No. Residential permit requirements are administered through the city, county, or other authority responsible for the property and project.

Does every Texas building permit require a plot plan?

No. Interior-only work and certain exempt repairs may not require one. Projects involving new buildings, additions, pools, garages, sheds, decks, driveways, and other exterior changes are more likely to require site information.

Can a county appraisal map be used as my property survey?

No. Appraisal-district GIS data is generally intended for informational and tax-appraisal purposes. It does not independently locate or certify legal property boundaries.

Can I use the survey from when I bought my home?

It may be a useful base document if it is readable and still accurately shows the property. The local permit authority may request an updated survey or additional information depending on the project.

What should a Texas plot plan show?

It commonly shows the complete property, existing structures, proposed work, dimensions, property-line distances, streets, access, easements, building lines, north arrow, and scale. Additional information depends on the project and jurisdiction.

Does the plot plan need to be drawn to scale?

Many Texas authorities require a scaled drawing. Some may accept a fully dimensioned plan for certain minor projects. Follow the current local checklist.

Do I need to show every setback?

Show the actual proposed distances to the property lines and other restrictions relevant to the project. Do not rely only on a generic setback line.

Do easements need to appear on the plot plan?

Known easements should be shown when they affect the property or proposed construction. The authority may request the recorded instrument or a licensed survey.

Can I draw the plot plan myself?

Some jurisdictions allow homeowner- or contractor-prepared drawings for certain residential projects. The drawing must still satisfy the applicable requirements, and licensed surveying or engineering must be obtained when required.

When do I need a Texas land surveyor?

A surveyor may be needed when boundaries are uncertain, the project is close to a property line, certified elevations are required, an easement location is unclear, or the local checklist expressly requires professionally verified information.

Are deed restrictions and HOA approval part of the building permit?

Not necessarily. Private deed restrictions or HOA review can apply separately from the government permit. One approval does not automatically replace the other.

Are USA Site Plans drawings signed or sealed?

No. USA Site Plans provides drafting services. Licensed surveying, architecture, engineering, and professional seals must be obtained separately when required.

Will a Texas plot plan guarantee permit approval?

No. The reviewing authority controls the permit decision and may request corrections, a licensed survey, engineering, construction drawings, or other supporting documents.
