USA Site Plans
Residential permit drawing guide
Many site-plan corrections are caused by information that is missing, difficult to read, inconsistent with other drawings, or unsupported by reliable property documents. A careful pre-submission review can help prevent those avoidable problems.
Order Your Site Plan Site Plan Checklist Permit Site Plan GuidePermit timing depends on the reviewing jurisdiction, project type, application volume, zoning compliance, required agency reviews and the completeness of the entire submission. A clear site plan can help reviewers understand the proposal and avoid corrections caused solely by missing or unclear site information.
A permit reviewer should be able to identify the property, understand the proposed work and locate the important measurements without having to interpret an incomplete sketch.
A well-prepared site plan commonly answers these questions:
- Which property is being developed?
- What buildings and improvements already exist?
- What construction is proposed?
- How large is the proposed project?
- Where will it be located within the property?
- How far is it from the property boundaries?
- Does it affect an easement, driveway, utility or drainage feature?
- Does the site plan agree with the application and construction drawings?
When the drawing does not answer these questions clearly, the reviewing authority may request revisions, supporting records, a survey or additional professional documents.

Permit applications can be returned for many reasons. Some involve the project itself, while others involve the quality or completeness of the submitted documents.
Common document-related problems include:
- Property boundaries are missing or unclear
- Lot dimensions are incomplete
- Existing structures are omitted
- The proposed work is not clearly distinguished
- Project dimensions are missing
- Distances to property lines are not shown
- The site plan conflicts with the floor plans
- Known easements are omitted
- Driveways, alleys or access routes are missing
- The drawing is blurry, cropped or difficult to read
- A basic drafted plan is submitted where a survey or licensed design is required
A correction request does not necessarily mean that the project has been denied. It often means that the reviewer needs additional or revised information before completing the review.

The Eight Essentials of a Reviewable Site Plan
How to Avoid Preventable Site Plan Permit Delays
1. Confirm the Correct Reviewing Jurisdiction
A postal address does not always identify the correct permit authority.
A property can be:
- Inside a city or town
- In an unincorporated county area
- Within an extraterritorial jurisdiction
- Inside a special district
- Subject to review by more than one agency
The wrong jurisdiction can mean the wrong:
- Permit application
- Site-plan checklist
- Zoning regulations
- Submission portal
- Fee schedule
- Review process
Confirm the jurisdiction before preparing the final plan set.
2. Use the Current Project-Specific Checklist
Do not assume that one general checklist applies to every project.
A shed, pool, addition, driveway and accessory dwelling can have different requirements.
A project-specific checklist may request:
- A certified survey
- A basic dimensioned site plan
- Topographic information
- Impervious-area calculations
- Tree information
- Drainage or grading plans
- Floodplain documents
- Professionally signed and sealed plans
Use the current checklist issued by the authority reviewing the application. Older forms and third-party summaries can be incomplete or outdated.
3. Show the Complete Property
A permit site plan should normally show the complete lot rather than only the immediate construction area.
Include:
- Front property line
- Both side property lines
- Rear property line
- Street-side line on a corner lot
- Angled or irregular boundary segments
- Available lot-line dimensions
- Adjoining streets and alleys
The full property can be important for reviewing:
- Setbacks
- Lot coverage
- Accessory-structure limits
- Parking
- Vehicle access
- Easements
- Environmental conditions
A fence, hedge, retaining wall or pavement edge should not automatically be treated as the legal property boundary.
4. Use Reliable Property Information
Every project location and setback measurement depends on the property information used for the drawing.
Useful sources can include:
- Licensed boundary survey
- Recorded subdivision plat
- House-location survey
- Previous approved site plan
- Deed or legal description
- Official parcel records
Aerial imagery and GIS maps can support preliminary research, but they do not independently establish legal boundaries.
A licensed surveyor may be needed when:
- Property corners cannot be located
- The proposed work is close to a boundary
- The lot is irregular
- Available documents conflict
- Certified elevations are required
- The permit checklist specifically requires a survey
5. Show Every Relevant Existing Improvement
The proposed project cannot be reviewed accurately when important existing conditions are missing.
Depending on the property, show:
- Main house or principal building
- Existing additions
- Attached and detached garages
- Carports
- Sheds and workshops
- Decks and porches
- Patios and walkways
- Swimming pools and spas
- Driveways and parking
- Retaining walls
- Fences and gates when relevant
An omitted structure can affect building separation, coverage calculations, access and the amount of space available for new construction.
6. Make the Proposed Work Easy to Identify
A reviewer should not have to guess which part of the drawing is proposed.
Use:
- A clear “PROPOSED” label
- A distinct hatch pattern
- A heavier outline
- A different 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-equipment pads
- New paving
- Structures proposed for demolition
A vague circle, arrow or approximate shaded area is rarely a substitute for a dimensioned project footprint.
7. Dimension the Proposed Project
Show the complete proposed length and width.
An irregular project should include enough dimensions to define the full shape.
The site-plan dimensions should agree with:
- Permit application
- Foundation plan
- Floor plan
- Exterior elevations
- Structural drawings
- Manufacturer or contractor plans
A 12-by-16-foot addition on the site plan should not become a 12-by-18-foot addition on the foundation drawing.
Review every sheet as one coordinated permit package.
8. Show Actual Property-Line Distances
Do not show only a generic zoning setback line.
Dimension the actual proposed distance from the project to the relevant:
- Front property line
- Left-side property line
- Right-side property line
- Rear property line
- Street-side boundary on a corner lot
- Recorded building line
- Easement boundary
Use the shortest relevant distance.
Do not expect the reviewer to calculate the setback from the drawing scale.
Setback requirements can depend on:
- Zoning district
- Project type
- Structure height
- Lot configuration
- Corner-lot status
- Roof projections
- Overlay districts
- Previous zoning approvals
Read Setbacks and Zoning: How to Find the Rules for Your Property and Property Setbacks Explained for Homeowners .
9. Show Building Separation
Property-line setbacks are not the only important distances.
The plan may also need to show the distance between the proposed project and:
- Main house
- Detached garage
- Shed
- Accessory dwelling unit
- Deck or porch
- Other buildings
Building separation can affect:
- Fire resistance
- Access
- Structure classification
- Zoning compliance
- Utility clearances
10. Include Streets, Driveways and Access
A site plan should explain how the property connects to the public way and how the proposed project will be accessed.
Show relevant:
- Adjoining street name
- Public alley
- Driveway
- Parking area
- Garage entrance
- Public sidewalk
- Curb or roadside ditch
- Pedestrian walkway
- Vehicle and pedestrian gates
A garage or carport application without a driveway connection can leave a major part of the proposal unexplained.
Work inside a public right-of-way can require a separate public works or transportation permit.
11. Identify Known Easements and Restrictions
A proposed structure can satisfy its zoning setback and still conflict with a recorded easement.
Show known:
- Utility easements
- Drainage easements
- Sewer easements
- Access easements
- Shared-driveway easements
- Conservation easements
- Recorded building lines
- Environmental buffers
Easement information may be found on:
- Property survey
- Recorded plat
- Title documents
- Recorded easement instrument
- Previous approved plans
The easement holder or reviewing authority may require a separate approval for work proposed inside an easement.
12. Add Project-Specific Site Information
Some information is required only for particular properties or projects.
This may include:
- Existing and proposed impervious area
- Lot or building coverage calculations
- Existing and proposed elevations
- Contour lines
- Drainage direction
- Floodplain boundaries
- Private well and septic systems
- Protected trees
- Wetlands, streams and buffers
- Retaining walls
- Utility locations
Do not overload a simple drawing with irrelevant information, but do not omit details specifically requested by the local checklist.
13. Keep the Drawing Readable
The plan should remain understandable at the submitted sheet size.
Use:
- Readable text
- Consistent line weights
- Clear dimension strings
- A logical drawing scale
- Enough space between labels
- A north arrow
- A written scale
- A graphic scale bar when useful
Avoid:
- Overlapping dimensions
- Blurry screenshots
- Cropped property boundaries
- Text placed over structures
- Unexplained abbreviations
- Multiple conflicting project versions
For more guidance, read Site Plan Design for Permit Applications .
14. Compare the Site Plan With Every Other Drawing
The permit package should describe one consistent project.
Compare the site plan with:
- Permit application
- Floor plans
- Exterior elevations
- Foundation plans
- Roof plans
- Structural drawings
- Manufacturer plans
- Engineering documents
Check:
- Project length and width
- Building orientation
- Stair location
- Door and garage-door direction
- Roof projections
- Structures being removed
- Revision dates
When one sheet changes, review every affected drawing before resubmission.
15. Submit the Correct Type of Professional Document
A drafted site plan is not interchangeable with every property or construction document.
Submitting a basic drafted plan where a licensed survey, topographic plan or sealed engineering drawing is required will usually result in a request for the correct document.
Incomplete vs Reviewable Site Plans
| Incomplete or unclear submission | Reviewable submission |
|---|---|
| Only the backyard or project area is shown | The complete property and adjoining public ways are shown |
| The proposed project is marked approximately | The complete footprint is clearly identified and dimensioned |
| A fence or GIS line is used as the boundary | Reliable property documents are used and limitations are recognized |
| Setbacks are left for the reviewer to estimate | Actual proposed distances are dimensioned |
| Existing garage, shed or deck is omitted | Relevant existing improvements are included |
| The site plan and floor plan show different sizes | All sheets describe the same project |
| Easements and access are ignored | Known restrictions and access routes are identified |
| Text and dimensions overlap | Labels and measurements remain readable at the submitted scale |
| A drafted plan is used instead of a required survey | The correct licensed or certified document is included |
A Practical Pre-Submission Workflow
What to Do When You Receive Permit Comments
Read the entire correction notice before changing the drawings.
A useful response process is:
- List every comment. Do not address only the first issue.
- Identify every affected document. One correction may require changes to several sheets.
- Confirm the requested standard. Review the cited checklist, code section or department instruction.
- Update the drawing consistently. Correct dimensions, labels and notes across the permit set.
- Use the required revision method. Follow the portal’s naming, clouding or revision-date requirements.
- Review before resubmitting. Make sure the correction did not create a new conflict elsewhere.
Do not erase or change a dimension on one drawing while leaving the original measurement elsewhere in the package.
What a Site Plan Cannot Fix
A clean drawing cannot make a noncompliant project compliant.
A permit application may still need:
- A revised project location
- A smaller structure
- Zoning relief or a variance
- Historic-district approval
- Floodplain review
- Tree-removal approval
- Public right-of-way approval
- A licensed survey
- Architectural or engineering plans
- Additional agency approval
The role of the site plan is to communicate the actual proposal clearly. It does not replace the regulations or professional services applying to the project.

Frequently Asked Questions
Can a complete site plan guarantee permit approval?
No. Approval depends on the project, property, applicable regulations and complete permit package. The reviewing authority may still request revisions or additional supporting documents.
Can a clear site plan shorten the review time?
Review timing is controlled by the permit authority. A clear drawing can help prevent corrections caused solely by missing, unclear or inconsistent site information, but it cannot guarantee a particular review period.
What is the most common site-plan problem?
Common problems include missing property-line distances, incomplete boundaries, omitted existing structures, unclear proposed work and conflicts between the site plan and construction drawings.
Should the complete property be shown?
Many reviewing authorities expect the complete lot because setbacks, coverage, access, easements and other conditions can depend on the overall property layout.
Do I need to show actual setbacks?
Show the actual proposed distances from the project to the relevant property lines. Do not rely only on a generic setback line or expect the reviewer to calculate the distance from scale.
Can I use a fence as the property boundary?
Not automatically. Fences are sometimes offset from legal boundaries. Use reliable property documents and obtain a licensed survey when certified boundary information is required.
Do existing sheds and garages need to be shown?
Relevant existing structures should generally be shown because they can affect building separation, lot coverage, access and the available location for the proposed work.
What happens when the site plan and floor plan show different dimensions?
The reviewing authority may request coordinated revisions. Every plan sheet should describe the same project size, orientation and location.
Do easements need to be shown?
Known easements should be shown when they affect the property or proposed work. The authority may also request the recorded easement document or a licensed survey.
Can an online map replace a survey?
No. Online maps can support preliminary research but do not independently locate or certify legal property boundaries.
Can I draw a site plan myself?
Some jurisdictions allow homeowners or other responsible parties to prepare site plans for certain projects. The drawing must still satisfy local requirements. Licensed surveying, architecture and engineering must be obtained separately when required.
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.
