Before starting a construction or improvement project, one important question must be answered: What drawings and documents will your local building department require? A fence, shed, pool, deck, ADU, home addition, or commercial project may each have different permit requirements.
Many homeowners and contractors submit a permit application with incomplete drawings because they assume that one site plan is enough. However, some projects also require floor plans, elevation drawings, structural details, surveys, zoning information, or other supporting documents.
A permit requirement checker helps you understand what your project may need before you submit your application. It can guide you through the main drawing requirements, identify missing information, and help you choose the right permit-ready drawing package.
At Permit For Site Plan, we help homeowners, contractors, developers, and business owners prepare accurate site plans and supporting permit drawings for projects across the United States. This guide explains how permit requirements work, which drawings different projects usually need, and how to reduce avoidable permit delays.
Why Most Homeowners Get Permit Requirements Wrong
The assumption most people bring to a permit application is that any drawing attached to the form is enough to start review. That assumption is the source of most preventable delays.
Building departments across the United States operate under specific checklists. A reviewer sitting with your application is not evaluating your project for the first time with fresh eyes and goodwill. They are running through a standardized list of required elements and marking everything that is absent. The moment one required item is missing a setback distance, a north arrow, a labeled property line the application is flagged. In many jurisdictions, it is placed on hold. In others, it is rejected outright, and the filing fee does not transfer to the resubmission.
The consequences are real and they compound quickly:
- Applications placed on hold can sit for days or weeks while you prepare a corrected drawing
- Rejected applications require a full resubmission with a second filing fee in many cities
- Correction cycles delay your project start date by weeks sometimes months in high-volume permit offices
- Contractors who are scheduled may become unavailable by the time the permit is finally issued
- Financing that is tied to permit approval milestones can be disrupted
What makes this particularly frustrating is that in most cases, the project itself was never the problem. The project was compliant. The drawing simply did not communicate that compliance clearly enough for the reviewer to confirm it. A permit requirement checker addresses this problem before it starts by helping you identify what your city needs to see before you submit anything.
What Is a Permit Requirement Checker for Site Plans?
A permit requirement checker is a tool or guided review process that helps you identify the drawings, documents, and project details that may be required for a building permit.
Instead of guessing which documents to submit, you can review your project type, location, construction scope, and current permit status. The result helps you understand whether you may need a basic site plan, an advanced site plan, a floor plan, elevation drawings, structural drawings, or a complete permit drawing package.
A permit requirement checker may consider questions such as:
- What type of project are you planning?
- Where is the property located?
- Are you applying for a new permit or correcting an existing application?
- Do you already have a survey, old site plan, contractor sketch, or correction notice?
- Will the project change the building footprint, height, exterior appearance, or property coverage?
The exact requirements depend on your city, county, zoning district, and project conditions. Therefore, a permit requirement checker should be used as a planning tool, not as a replacement for your local building department’s official checklist.
Why You Should Check Permit Requirements Before Construction
Permit problems often begin before the application is submitted. A drawing may look complete to a homeowner but still miss information that a plan reviewer needs.
For example, a site plan may show a proposed deck but fail to include setback distances. A pool plan may show the pool location but omit the equipment pad or safety barrier. An ADU application may include a site plan but lack the required floor plan and elevation drawings.
These issues can lead to:
- Correction notices from the building department
- Delayed permit review
- Additional drafting costs
- Resubmission fees
- Delays to contractor scheduling and construction
A pre-submission review gives you the opportunity to identify these issues early. It also helps ensure that your permit application, site plan, and other drawings describe the same project.
What Drawings Are Usually Needed for a Building Permit?
Not every project requires the same drawing package. The required documents depend on the type of work and the rules of your local jurisdiction.
Site Plan for Building Permit
A site plan shows the property from above. It identifies the lot boundaries, existing structures, proposed improvements, setbacks, driveways, easements, utilities, and other relevant site features.
A typical permit-ready site plan may include:
- Property lines and lot dimensions
- Project address and parcel information
- Existing buildings and structures
- Proposed construction or improvement
- Setback distances
- North arrow and drawing scale
- Driveways and site access
- Easements and utilities where applicable
- Lot coverage calculations when required
A building permit site plan helps the reviewing authority understand where the project will be located and whether it may comply with zoning and property restrictions.
Floor Plan
A floor plan shows the interior arrangement of a building from a top-down view. It usually includes rooms, walls, doors, windows, stairs, fixtures, dimensions, and circulation areas.
A floor plan may be required for:
- Home additions
- ADUs
- Garage conversions
- New home construction
- Interior remodeling
- Commercial improvements
The floor plan service can be useful when your project requires more than a site layout. The floor plan should coordinate with the site plan so the building footprint and dimensions match across the drawing package.
Elevation Plan
An elevation plan shows the exterior faces of a building from the front, rear, left, and right sides. It explains the building’s height, roofline, exterior materials, windows, doors, and relationship to finished grade.
Elevation drawings are commonly needed for:
- New construction
- ADUs
- Home additions
- Garage construction
- Exterior remodeling
- Projects that change roof height or building appearance
Learn more about elevation plans and how they support permit review and design approval.
Structural and Technical Drawings
Some projects require additional technical documents, including foundation plans, framing details, retaining wall drawings, structural calculations, or engineering documents.
These requirements are more common for elevated decks, major additions, new construction, retaining walls, commercial buildings, and projects involving structural changes. Depending on the jurisdiction, a licensed architect or engineer may need to prepare or stamp specific documents.
Project Types and Their Common Permit Drawing Requirements
Fence Permit
A fence project may require a basic site plan showing the property boundaries, fence location, fence height, materials, and setback distances.
Corner lots and properties near sidewalks, streets, utility easements, or drainage areas may have additional requirements. Review your local fence rules before assuming that a permit is unnecessary. You can explore the fence permit site plan service for help preparing the required layout.
Shed Permit
A shed permit usually requires a site plan showing the shed footprint, location, dimensions, and distance from property lines. Some jurisdictions exempt small sheds from permits, but exemption limits vary. A shed may still require approval if it includes electrical work, plumbing, a foundation, or a larger footprint.
Deck and Patio Permit
A deck or patio site plan should show the location of the improvement, its dimensions, relationship to the house, and setbacks from property lines.
An elevated deck may also require structural drawings, footing details, framing plans, or elevation drawings. Attached patio covers and pergolas may require additional information about roof height and connections to the existing structure. See the deck permit service for more information.
Swimming Pool Permit
Pool permits often require a detailed site plan showing the pool location, property setbacks, pool dimensions, equipment pad, safety barrier, fencing, and relationship to existing structures.
Some jurisdictions also review drainage, lot coverage, septic system clearances, and utility locations. A pool project may need more than a simple property sketch. Our pool permit site plan service can help organize the required site information.
ADU Permit
An accessory dwelling unit usually requires a more complete permit drawing package. Depending on local rules, this may include:
- Site plan
- ADU floor plan
- Elevation drawings
- Parking information
- Utility connections
- Setback measurements
- Building height and lot coverage details
The ADU site plan service supports projects that need coordinated site and building information.
Home Addition and Garage Permit
A home addition or garage project normally requires the reviewer to understand both the existing property and the proposed changes. The drawing package may include a site plan, floor plan, elevation drawings, and structural details. Existing and proposed work should be clearly labeled so the reviewer can identify what is changing.
For garage projects, the site plan should also show driveway access and the relationship between the garage and other structures. You can review the garage permit service for project-specific support.
Commercial Project
Commercial permit requirements are usually more detailed than residential requirements. Depending on the project, the package may include site plans, floor plans, elevations, parking layouts, accessibility information, landscaping, utilities, fire access, and mechanical, electrical, plumbing, or structural drawings.
Commercial projects may also require professional stamps from a licensed architect or engineer. Before ordering drawings, confirm the submission requirements with the relevant authority.
Site Plan Checklist for Permit Submission
Before submitting your application, check whether your drawing package includes the important information below:
- Property address and parcel identification
- Accurate property lines and lot dimensions
- Existing structures and proposed improvements
- Setback distances from property lines
- North arrow and stated drawing scale
- Driveway, access, easements, and utilities where applicable
- Required floor plans, elevation drawings, or structural documents
The checklist may change based on your project and location. You should always compare your drawing package with the official requirements of your city or county. For additional guidance, review our building permit requirements and residential permit submission checklist.
Common Permit Drawing Mistakes to Avoid
Missing Setback Dimensions
Showing a structure without labeling its distance from property lines can result in a correction notice. Setbacks should be clearly dimensioned for all regulated structures.
Incorrect or Incomplete Property Lines
A drawing based only on memory or rough measurements may not accurately represent the property. Use reliable parcel information, survey data, or other approved sources whenever possible.
No North Arrow or Scale
A permit drawing should communicate orientation and real-world dimensions. Missing scale information or a north arrow can make the plan difficult to review.
Existing and Proposed Work Are Mixed
Clearly separate existing structures from proposed construction. Use labels such as “EXISTING” and “PROPOSED” to avoid confusion.
Required Drawings Are Missing
A site plan alone may not be enough for an ADU, addition, garage, commercial project, or new construction. Check whether floor plans, elevation drawings, or structural details are also required.
Drawings Do Not Match the Application
The project address, dimensions, building footprint, and project description should match across the permit application and drawing package. Inconsistencies can create unnecessary review questions.
If your application has already been rejected, our permit correction plan revision service can help address reviewer comments and prepare revised drawings.
How to Use a Permit Requirement Checker
Start by selecting your project type and identifying the city or county where the property is located. Next, review the documents you already have, such as a survey, old plan, property photographs, contractor sketch, or correction notice.
Then identify whether you need:
- A site plan only
- A site plan with a floor plan
- A site plan with elevation drawings
- A complete permit drawing package
- Revisions to an existing or rejected plan
Once you understand the likely requirements, compare them with the official local checklist. If the project is complex, request a professional review before submitting the application.

Final Thoughts
A permit requirement checker is a useful first step for understanding the documents your project may need. It helps you avoid guesswork, organize your information, and identify possible gaps before submitting your permit application. However, permit requirements vary by location and project type. A checker cannot guarantee approval, and the final decision always belongs to the local building department.
For the best results, prepare a coordinated permit-ready drawing package that includes the correct site plan, floor plan, elevation drawings, and technical documents when required. If you are unsure where to begin, Permit For Site Plan can help you identify the appropriate service and prepare drawings based on your project details.
