If you are applying for a building permit, there is a good chance the city or county will ask for a site plan.

For many homeowners, this can feel intimidating at first because they are unsure what a site plan should include or how detailed it needs to be.

The good news is that most residential permit site plans follow a fairly standard layout.

Once you understand the basic structure, it becomes much easier to understand what reviewers expect to see during permit review.

A permit site plan is essentially a scaled overhead drawing of your property that shows existing conditions and proposed construction.

Cities use site plans to verify:

• property layout,
• setbacks,
• structure placement,
• access and driveways,
• zoning compliance,
• overall site organization.

Before starting, homeowners can review the

to understand the property and project information commonly needed.

What Is a Site Plan for a Building Permit?

Step 1: Gather Property Information

Before drawing the site plan, gather as much property information as possible.

This often includes:

• property survey or plat map,
• lot dimensions,
• existing structures,
• driveway layout,
• setback requirements,
• easement information,
• local zoning requirements.

The more accurate your starting information is, the easier it becomes to prepare a cleaner and more reliable site plan.

Many homeowners use property surveys because they already contain lot dimensions and property boundary information.

A drafted site plan is not the same as a licensed boundary survey. Our guide comparing a

site plan and property survey

explains the role of each document and when certified boundary information may be required.

Step 2: Draw the Property Lines

The first major step is outlining the property boundaries.

Your site plan should clearly show:

• front property line,
• rear property line,
• side property lines,
• overall lot dimensions.

Property lines are extremely important because reviewers use them to verify setbacks and zoning compliance.

If the lot shape or dimensions are incorrect, the rest of the site plan may become unreliable.

Do not automatically treat a fence, hedge, driveway edge, or landscape border as the legal property line. Those visible features may not follow the recorded boundary exactly.

Step 3: Add Existing Structures

After drawing the property boundaries, add the structures that already exist on the property.

This may include:

• existing house,
• garage,
• shed,
• pool,
• deck or patio,
• driveway,
• walkways,
• fences.

Cities need to understand the current site conditions before reviewing the proposed project.

This helps reviewers evaluate spacing, setbacks, access, and overall lot layout.

Label existing structures clearly. If a structure will be demolished or removed as part of the project, identify it separately so the reviewer can distinguish existing, removed, and proposed work.

Step 4: Add the Proposed Project

Next, draw the proposed construction clearly on the site plan.

This could include:

• home additions,
• garages,
• sheds,
• decks,
• pools,
• fences,
• driveway extensions,
• ADUs.

The proposed work should be clearly labeled so reviewers can immediately understand what is being built.

Include the proposed project’s length, width, footprint, and location. Depending on the project, the plan may also need to show stairs, posts, gates, roof overhangs, equipment pads, parking areas, or utility connections.

One of the most common permit mistakes is failing to distinguish proposed work from existing conditions.

Step 5: Show Setbacks and Dimensions

Setbacks are one of the most important parts of the site plan.

Most cities want to see the distance between the proposed structure and the property lines.

Common setback measurements include:

• front setback,
• rear setback,
• side setbacks,
• distance between structures.

The plan may also need to show dimensions from roof overhangs, steps, decks, equipment, pavement, or other project elements when they extend beyond the main structure footprint.

Missing setback dimensions are one of the most common reasons permit applications get delayed.

Reviewers rely heavily on these measurements during zoning review.

Step 6: Add Easements and Utilities When Required

Some permit applications also require easements and utility areas to be shown.

This may include:

• utility easements,
• drainage easements,
• access easements,
• power lines,
• water or sewer connections.

Structures placed inside easements can trigger permit corrections or additional review.

That is why many cities require easements to be shown clearly on the site plan.

Use a survey, subdivision plat, title document, utility record, or other available property document to identify known easements. Utility locations should be treated as approximate unless they have been professionally located or verified in the field.

Step 7: Show Driveways, Streets, and Access

A complete site plan should help reviewers understand how people and vehicles reach the property and proposed project.

Depending on the project, show:

• existing driveway,
• proposed driveway or paved extension,
• sidewalk,
• street name,
• alley access,
• walkways,
• gates,
• parking or turnaround areas.

Driveway and access details are particularly important for garages, carports, ADUs, parking pads, and projects that affect the curb or public right-of-way.

Step 8: Include a North Arrow and Drawing Scale

Most permit-ready site plans include:

• a north arrow,
• a drawing scale.

These technical details help reviewers understand orientation and proportion.

Even simple residential site plans usually include these items because they are standard drafting requirements.

Missing scale or orientation is another common reason plans get flagged during review.

Choose a scale that allows the entire property and all necessary dimensions to fit clearly on the drawing sheet. Text and measurements should remain readable after the plan is converted to PDF and uploaded.

Step 9: Label Everything Clearly

Readability matters more than many homeowners realize.

Your site plan should clearly label:

• property lines,
• existing structures,
• proposed construction,
• setbacks,
• street name,
• dimensions,
• driveways and access points.

If the reviewer struggles to understand the drawing quickly, the permit review process often slows down.

A clean, organized layout helps reviewers process the application much faster.

Use consistent line styles, text sizes, dimension arrows, and labels. Existing and proposed features should be easy to distinguish without relying on guesswork.

Step 10: Compare the Drawing With the Permit Checklist

Before submitting, compare the completed site plan with the checklist provided by your city, county, or HOA.

Check that the drawing includes:

• correct property address,
• property boundaries and dimensions,
• existing structures,
• proposed work and project dimensions,
• setback measurements,
• driveway and access information,
• known easements and utilities,
• north arrow and scale,
• clear existing and proposed labels.

A checklist review can catch small omissions before they become formal correction comments.

for another practical submission review.

What Reviewers Usually Check First

When reviewers first open a site plan, they usually check:

• property boundaries,
• project placement,
• setbacks,
• existing structures,
• overall clarity.

They may then review access, easements, drainage, utilities, lot coverage, and project-specific information.

If those items are easy to understand, the permit review process usually moves faster.

If they are missing or unclear, correction comments often follow.

Can You Draw Your Own Site Plan?

Some jurisdictions allow homeowners to prepare their own site plans for straightforward residential projects.

Whether a homeowner-prepared plan is accepted depends on:

• the local permit office,
• the type and size of the project,
• the property conditions,
• the accuracy of the available information,
• whether licensed or stamped documents are required.

A hand-drawn plan may be accepted in some situations if it is accurate, scaled, complete, and readable. Other jurisdictions require a more formal digital drawing, survey, engineered plan, or architect-prepared document.

Common Site Plan Problems to Avoid

Even a visually attractive site plan can be returned if it does not provide the information needed for review.

Common problems include:

• incorrect or missing property lines,
• unlabelled proposed work,
• missing project dimensions,
• missing setbacks,
• existing structures left off the plan,
• driveways, streets, or alleys not shown,
• easements ignored,
• no north arrow or scale,
• blurry or cropped PDF files,
• information that conflicts with the survey or permit application.

Final Thoughts

Learning how to draw a site plan for a permit helps homeowners better understand the permit process and the information cities expect before approval.

A clear site plan helps reviewers evaluate setbacks, property layout, structure placement, access, easements, and zoning compliance more efficiently.

Whether you create the site plan yourself or use a professional service, the goal is the same: provide a clean, readable layout that helps the permit review process move smoothly.

A site plan can support the application, but it does not guarantee permit approval and does not replace a licensed survey, engineering, architectural drawings, or other documents required by the local authority.

The clearer and more organized the site plan is, the easier the permit process usually becomes.
