How to Draw a Site Plan for a Shed Permit (Complete Guide)

By Site Plan Creator Team • March 8, 2026

Why Your Shed Permit Needs a Professional Site Plan

You've picked out the perfect shed. You know exactly where you want it — tucked into the back corner of your yard, close enough to the garden to be useful, out of the way enough to keep the neighbors happy. You head to your local building department to pull a permit, and that's when it happens: the clerk slides a checklist across the counter and points to item number three. Site plan required.

For many homeowners, this is where the process grinds to a halt. A shed seems like such a simple project — four walls, a roof, maybe a set of double doors. Why does it need a formal drawing? The answer is straightforward: your municipality needs to verify that your proposed shed complies with local zoning regulations before construction begins. That means confirming setbacks from property lines, checking that the structure won't encroach on easements, and ensuring the total lot coverage stays within legal limits.

The good news is that a shed site plan doesn't need to be an architectural masterpiece. It does, however, need to be accurate, clearly labeled, and drawn to scale. This guide will walk you through every element of a compliant shed permit site plan — from understanding what information to include, to the tools you can use to create a professional drawing without hiring a surveyor or architect.

What Is a Shed Site Plan and Why Do Municipalities Require It

A shed site plan (sometimes called a shed permit diagram or shed permit drawing) is a bird's-eye view drawing of your property that shows the location of your proposed shed in relation to your property boundaries, existing structures, and other relevant features.

Think of it as a map of your lot. From above, a reviewer at the building department can instantly see:

- Where your property lines are
- Where your house, driveway, and other existing structures sit
- Exactly where the new shed will be placed
- The distances (setbacks) from the shed to each property line
- Whether the shed falls within any easements or restricted zones

Without this drawing, a permit reviewer has no way to evaluate whether your project complies with local zoning codes. Even if your shed is perfectly legal, the permit cannot be issued without documented proof of compliance. That's why nearly every jurisdiction in the United States — and most in Canada and the UK — requires a site plan as part of a shed permit application.

When Is a Shed Permit Required?

Permit requirements vary by location, but as a general rule, you'll need a building permit for a shed if it:

- Exceeds a certain square footage (commonly 100–200 sq ft, though this varies widely)
- Has a permanent foundation
- Has electrical or plumbing connections
- Is located in a regulated zone such as a flood plain or historic district

Even if your shed falls below the permit threshold, some municipalities still require a zoning approval or administrative review — and a site plan is almost always part of that process. When in doubt, call your local building department before you start construction.

What to Include in a Shed Permit Site Plan

This is the section that most homeowners get wrong. They submit a rough sketch of their backyard, get rejected, and then wonder why. A compliant shed site plan for a permit application needs to include specific elements, presented clearly and accurately.

1. Property Boundaries and Lot Dimensions

Every site plan starts with the outline of your property. This is not the outline of your yard — it's the legal boundary of your lot as recorded in your property deed and survey documents.

- Show all four (or more) property lines with their dimensions labeled in feet
- Include a north arrow so the reviewer can orient the drawing
- Note the street name and address on the plan
- If your lot is irregular, show all angles and dimensions clearly

Your property survey is the best source for this information. If you don't have one, check your deed, your title insurance documents, or contact your county assessor's office — many jurisdictions have parcel maps available online.

2. Existing Structures and Features

The site plan needs to show everything that already exists on the property, not just the new shed. This typically includes:

- Your primary dwelling (house) with its footprint dimensions
- Attached and detached garages
- Driveways and parking areas
- Patios, decks, and pools
- Fences and walls
- Utility boxes, meters, and AC units
- Any existing sheds or outbuildings

Label each structure clearly. You don't need interior floor plans — just the outline (footprint) of each structure as seen from above.

3. Proposed Shed Location and Dimensions

This is the star of your drawing. The proposed shed should be shown as a rectangle (or whatever shape it is) with:

- Overall dimensions labeled (length × width)
- Its position clearly shown relative to the house and property lines
- A label identifying it as "Proposed Shed" or "New Storage Structure"
- The finished floor elevation if required by your jurisdiction

4. Setback Dimensions — The Most Critical Element

Setbacks are the minimum required distances between a structure and the property lines. This is the information your permit reviewer cares about most, and it's the reason your shed site plan needs to be drawn accurately.

A shed setback diagram should show:

- The distance from the shed to the rear property line
- The distance from the shed to each side property line
- The distance from the shed to the front property line (if applicable)
- The distance from the shed to the primary dwelling (some codes require a minimum separation)

These dimensions should be shown with dimension lines — arrows or tick marks pointing from the shed to the property line, with the measurement labeled in between. Don't just write the number in a note somewhere; show it graphically on the drawing.

Typical residential setback requirements for sheds range from 3 to 10 feet from side and rear property lines, but your local zoning ordinance governs this. Look up your zone designation and find the accessory structure setback requirements before you finalize the shed location.

5. Easements and Utility Lines

If your property has recorded easements — utility easements, drainage easements, access easements — they must be shown on the site plan. Building a shed within an easement is almost always prohibited, and the permit reviewer will check for this.

Common easements to watch for:

- Utility easements along the rear or side of the property (often 10–20 feet wide)
- Drainage or stormwater easements
- Shared driveway or access easements

Your property survey or deed should list any recorded easements. If you're unsure, contact your county recorder's office.

6. Scale and North Arrow

A site plan must be drawn to scale. This means the distances on the drawing are proportionally accurate to real-world distances. Common scales for residential site plans include 1" = 10', 1" = 20', or 1" = 30'.

Always include:

- A written scale (e.g., "Scale: 1" = 20'")
- A graphic scale bar
- A north arrow

If your drawing isn't to scale, a permit reviewer cannot verify your setback dimensions visually, and many jurisdictions will reject the application outright.

7. Title Block and Project Information

In the corner of your site plan, include a simple title block with:

- Property address
- Owner name
- Date of drawing
- Drawing scale
- Revision number (if applicable)

This information helps the building department file your permit documents correctly and makes it easier to track revisions if changes are needed.

Step-by-Step: How to Draw a Shed Site Plan

Now that you know what needs to be on the plan, let's walk through the process of actually creating it.

Step 1: Gather Your Property Documents

Before you draw anything, collect the following:

- Your property survey or plat map
- Your deed (for lot dimensions and easement information)
- Your local zoning ordinance (specifically the section on accessory structures)
- Any HOA guidelines if applicable

Many county assessor websites now publish parcel maps with lot dimensions that you can use as a starting reference, though a recorded survey is always more authoritative.

Step 2: Determine Your Setback Requirements

Look up your property's zoning designation and find the setback requirements for accessory structures. Write these numbers down:

- Rear setback: _____ feet
- Side setback: _____ feet
- Front setback: _____ feet
- Separation from primary structure: _____ feet

These numbers will determine where you can legally place your shed.

Step 3: Measure Your Existing Property Features

Go outside with a measuring tape and record:

- The distance from your house to the rear property line
- The distance from your house to each side property line
- The location of any existing structures relative to the house and property lines
- The location of utility boxes, meters, and other fixed features

If you have a survey, you can pull most of these dimensions directly from the survey document. Field measurements are useful for confirming or supplementing survey data.

Step 4: Decide on Shed Placement

Using your setback requirements and your measurements, identify the buildable area of your lot — the zone where a shed can legally be placed. Mark this area out in your yard if it helps you visualize it.

Choose a location for your shed that:

- Meets all setback requirements with a comfortable margin
- Avoids all easements
- Doesn't conflict with utility lines (call 811 before digging)
- Works practically for your intended use

Step 5: Choose Your Drawing Method

This is where many homeowners face a decision. There are several ways to create a shed permit drawing:

Option A: Hand Drawing
Using graph paper, a ruler, and a pencil, you can draw a site plan by hand. This works, but it's time-consuming, difficult to keep accurate, and hard to revise. If you make a mistake, you may need to start over. Hand-drawn plans are accepted by most jurisdictions, but they often look unprofessional and can raise questions from reviewers.

Option B: General-Purpose CAD or Design Software
Programs like AutoCAD or SketchUp can produce professional drawings, but they have steep learning curves and are overkill for a simple shed site plan. Most homeowners don't have access to these tools or the time to learn them.

Option C: Browser-Based Site Plan Tools
This is the most practical option for most homeowners. Tools like Site Plan Creator are specifically designed for creating permit-ready site plans without CAD training. You can draw your property boundaries, place structures, add setback dimensions, and export a scaled, professional PDF — all in your browser, without installing any software.

Site Plan Creator includes built-in tools for drawing property lines, placing building footprints, adding dimension lines, and labeling features — everything you need to produce a compliant shed permit site plan in a fraction of the time it would take to draw by hand.

Step 6: Draw the Property Boundary

Start your drawing with the property outline. Using your lot dimensions from the survey or plat map, draw each property line to scale. Label each line with its dimension.

If your lot is a standard rectangle, this is straightforward. If your lot has an irregular shape — a curved front boundary, a pie-shaped lot, or multiple angles — take extra care to represent each segment accurately.

Step 7: Add Existing Structures

Using your field measurements, place the existing house footprint on the drawing, positioned correctly relative to the property lines. Add the garage, driveway, patio, and any other existing features.

Label everything clearly. Use simple text labels: "House," "Attached Garage," "Concrete Driveway," "Wood Deck."

Step 8: Place the Proposed Shed

Add the shed footprint to the drawing at your chosen location. Label it "Proposed Shed" and include its dimensions.

Now add your setback dimension lines. Draw a line from the edge of the shed to the nearest property line on each side, and label the distance. This is your shed setback diagram — the visual proof that your shed meets the required setbacks.

Step 9: Add Easements, North Arrow, and Scale

If your property has easements, draw them on the plan as dashed or hatched zones with a label identifying the type of easement.

Add your north arrow, scale notation, and title block. Review the drawing one more time against the checklist of required elements.

Step 10: Export and Submit

Print or export your site plan as a PDF. Most building departments accept digital submissions, though some still require paper copies. Check with your local department for their preferred format and any specific size requirements (11"×17" is common for residential site plans).

Common Mistakes That Get Shed Site Plans Rejected

After reviewing what goes into a compliant plan, it's worth understanding what causes rejections — because these mistakes are extremely common.

1. No scale or incorrect scale — The drawing looks right but the dimensions don't add up when a reviewer checks them.
2. Missing setback dimensions — The shed is shown on the plan, but the distances to property lines aren't labeled.
3. Incorrect property line locations — The homeowner drew the fence line instead of the actual property line. These are often not the same.
4. Omitting easements — A shed is placed directly in a utility easement, which is an automatic rejection.
5. Incomplete title block — Missing the property address or date.
6. Not showing all existing structures — The permit reviewer needs to calculate total lot coverage, which requires knowing all existing impervious surfaces.
7. Shed placed in a front yard — Many zoning codes prohibit accessory structures in the front yard setback.

Shed Setback Requirements: What to Expect by Jurisdiction Type

Setback requirements vary enormously by location. Here's a general overview to help you understand what you might be dealing with:

Urban and Suburban Municipalities

In densely developed areas, setbacks are typically tighter. Side and rear setbacks for sheds commonly range from 3 to 5 feet. Some jurisdictions allow sheds to be placed up to the property line if they meet specific fire-resistance requirements.

Rural Counties

Rural areas often have more relaxed regulations. Setbacks of 10 to 25 feet from property lines are common, but there may be fewer restrictions on shed size.

HOA-Governed Communities

If you live in an HOA community, you may face additional restrictions on top of municipal zoning requirements — including rules about shed appearance, color, and placement. Always check your CC&Rs before designing your shed.

Flood Zones

Properties in FEMA-designated flood zones face additional requirements, including elevation requirements for any new structure. A shed site plan for a flood zone property may need to include finished floor elevation data and may require review by a licensed engineer.

Shed Site Plan Examples: What a Good One Looks Like

A well-drawn shed permit plan example will typically show:

- A clean, scaled outline of the lot with dimensions on all sides
- The house centered (or offset as appropriate) within the lot, with its footprint dimensions labeled
- Driveway, garage, and other existing features shown and labeled
- The proposed shed shown as a solid rectangle in the intended location
- Four dimension lines showing the distance from the shed to each relevant property line
- A north arrow in the upper right corner
- A scale bar and written scale
- A title block with the address, owner name, and date
- Any easements shown as dashed lines with labels

If your plan has all of these elements and the dimensions are accurate, you have a strong foundation for permit approval.

Frequently Asked Questions

Do I need a professional surveyor to draw a shed site plan?

In most cases, no. While a licensed surveyor is required to produce a legal boundary survey, a shed site plan for a permit application can typically be prepared by the property owner. You do need accurate lot dimensions, which you can get from an existing survey, your deed, or your county's parcel map records. If you don't have a recent survey and your property lines are unclear, it may be worth hiring a surveyor before you build — not necessarily for the permit drawing, but to avoid placing your shed on a neighbor's property.

What scale should I use for a shed site plan?

The most common scales for residential site plans are 1" = 10', 1" = 20', and 1" = 30'. The right scale depends on your lot size and the paper size you're working with. For a typical suburban lot, 1" = 20' works well on a standard 11"×17" sheet. The goal is to make the drawing large enough to read clearly while fitting all the information on the page.

Can I draw my shed site plan by hand?

Yes, hand-drawn site plans are accepted by most building departments, provided they are drawn to scale, clearly labeled, and include all required information. However, hand-drawn plans are harder to revise, more difficult to keep accurate, and often look less professional than digitally produced plans. Using a browser-based tool like Site Plan Creator produces a cleaner, more accurate result with significantly less effort.

What if my shed doesn't meet the setback requirements?

If your proposed shed location doesn't meet the required setbacks, you have a few options. First, reposition the shed to a compliant location. Second, apply for a variance from your local zoning board — this is a formal process that allows exceptions to zoning rules under specific circumstances, but it takes time and isn't guaranteed. Third, consider a smaller shed that may qualify for a permit exemption in your jurisdiction. Always explore repositioning first, as it's the fastest path to approval.

How long does it take to get a shed permit approved?

Permit timelines vary widely. In some jurisdictions, over-the-counter permits for simple sheds can be issued the same day if your application is complete and compliant. In others, especially in larger cities or during busy seasons, review can take 2–6 weeks. Having a complete, accurate site plan is one of the best ways to avoid delays caused by requests for additional information.

Does my shed site plan need to show utilities?

Most residential shed site plans don't require detailed utility mapping, but you should show utility easements if they exist on your property. If your shed will have electrical service, some jurisdictions may require a separate electrical plan. Always call 811 (in the US) before digging to locate underground utilities, regardless of what your site plan shows.

What's the difference between a site plan and a floor plan for a shed permit?

A site plan shows the property from above — where the shed sits on the lot relative to property lines and other structures. A floor plan shows the interior layout of the shed itself. Some permit applications require both; others only require the site plan. Check with your local building department to confirm exactly what drawings are required for your specific project.

Can I use Google Maps or Google Earth to create my shed site plan?

Google Maps and Google Earth imagery can be useful as a visual reference, but they should not be used as the sole basis for a permit site plan. Satellite imagery is not drawn to a consistent scale, property lines are not shown, and the imagery may be outdated. Use your property survey and field measurements as your primary data sources, and use satellite imagery only to help you visualize the layout.
