Site Plan Requirements Checklist for Permit Approval

One of the biggest reasons permit applications get delayed is simple: the site plan is missing information reviewers expect to see immediately.

In many cases, the proposed project may be allowed, but the application slows down because the site plan is incomplete, unclear, inconsistent, or missing one of the basic details the reviewing authority needs.

That is why a complete site plan checklist matters. A clear plan helps reviewers understand the property, proposed work, dimensions, setbacks, access, easements, and other relevant site conditions without unnecessary guesswork.

The goal is simple: make the drawing easy to review. Clearly show what is being built, where it will go, and how it relates to the rest of the property.

A frequent permit problem is not necessarily that the project fails review. It is that the site plan does not clearly show enough information for reviewers to evaluate it efficiently.

That can lead to correction notices, resubmittals, additional questions, and unnecessary back-and-forth before the permit can move forward.

This guide explains the core site plan requirements commonly used during residential permit review, what reviewers may look for first, and which checklist items can help prevent avoidable delays.

Quick Site Plan Requirements Checklist

A permit-ready residential site plan commonly includes the following items:

• Property address and basic project information
• Property lines and available lot dimensions
• Street name and property frontage
• North arrow and drawing scale
• Existing structures and site improvements
• Proposed structure or improvement
• Proposed project dimensions
• Setback measurements from property lines
• Distances between relevant structures
• Driveways, walkways, access, and parking areas
• Known easements, utilities, and rights-of-way
• Relevant drainage, grading, or site features
• Clear existing, proposed, and demolition labels
• Title block, notes, dates, and revision information

Not every permit requires every possible site detail. A small fence project may need less information than a home addition, ADU, pool, or detached garage.

The core goal is always the same: give reviewers enough reliable information to understand the property, identify the proposed work, and evaluate how it fits on the site.

Why the Site Plan Is Often Reviewed First

Before a reviewer studies structural details, framing notes, construction specifications, or product information, the site plan often provides the quickest overview of the application.

It helps reviewers understand:

• where the project sits on the property,
• how large the project is,
• how close it is to property lines,
• how it relates to existing structures,
• whether it appears to meet zoning setbacks,
• whether access is available,
• whether easements or restricted areas may be affected,
• whether the application is complete enough for further review.

If the site plan is incomplete or difficult to read, the application may slow down before deeper review begins.

A clear site plan helps reviewers determine whether the application is ready to continue or whether additional information is needed.

What Reviewers Check First on a Site Plan
.

1. Property Information

Every site plan should clearly identify the property and project being reviewed.

Depending on the jurisdiction, this may include:

• property address,
• lot number,
• parcel number or assessor parcel number,
• legal description where required,
• zoning designation where applicable,
• owner or applicant name where required,
• project description or permit type.

Reviewers use this information to confirm that they are evaluating the correct parcel and applying the correct zoning, overlay, development, or property-specific rules.

If basic property information is missing or conflicts with the application form, the permit office may request clarification before continuing.

2. Property Lines and Lot Dimensions

The site plan should clearly show the full property boundary.

Property lines form the basis for setback review, lot coverage, project placement, access, easement review, and overall zoning compliance.

The drawing should show available information such as:

• front property line,
• rear property line,
• side property lines,
• lot width,
• lot depth,
• individual boundary dimensions,
• the overall shape of the parcel,
• street or alley frontage.

A fence, hedge, curb, driveway edge, tree line, or landscape border should not automatically be treated as the legal property boundary. Visible site features do not always follow recorded lot lines.

When precise boundary verification is important, the local authority may require a licensed survey.

Why Accurate Property Lines Matter on a Site Plan

and

Site Plan vs Survey
.

3. Street Name and Property Frontage

The site plan should identify the street, road, alley, or other public access serving the property.

Showing the street frontage helps reviewers understand:

• which property line is the front lot line,
• where vehicle access occurs,
• whether the property is a corner lot,
• whether a secondary street-facing yard applies,
• where sidewalks, curbs, gutters, or rights-of-way are located.

Corner lots and through lots may have more than one street-facing boundary. Those properties may be subject to different setback, fence-height, driveway, or visibility requirements.

4. North Arrow and Drawing Scale

A permit site plan should normally include a clear north arrow and drawing scale.

These elements help reviewers understand orientation, proportion, and the relationship between property features.

A complete drawing may include:

• a north arrow,
• a written scale,
• a graphic scale bar where useful,
• consistent dimensions throughout the plan.

A plan marked “Not to Scale” may not be acceptable when the reviewing authority requires a scaled drawing.

Choose a scale that allows the complete property, project, dimensions, notes, and labels to remain readable when the plan is printed or uploaded as a PDF.

5. Existing Structures and Site Improvements

Reviewers need to understand what is already on the property before they can evaluate the proposed work.

Relevant existing features may include:

• the main house,
• attached or detached garage,
• carport,
• sheds and accessory buildings,
• decks and patios,
• pools and spas,
• driveways and parking areas,
• walkways,
• fences and gates,
• retaining walls,
• other permanent improvements.

Even when those features are not changing, they can affect setbacks, structure separation, access, lot coverage, drainage, parking, and the available building area.

If an existing structure will be removed, clearly label it as proposed demolition or removal rather than simply leaving it off the drawing.

6. Proposed Structure or Improvement

The proposed work should be immediately recognizable.

Reviewers should not have to guess what is new and what already exists.

Common residential projects include:

• decks,
• sheds,
• garages,
• pools,
• home additions,
• driveways,
• fences,
• carports,
• patio covers and pergolas,
• accessory dwelling units.

The proposed project should be clearly labelled and visually distinguished from existing conditions.

Depending on the project, the plan may need to identify:

• proposed footprint,
• length and width,
• roof overhangs,
• stairs and landings,
• posts or supports,
• gates,
• equipment pads,
• foundation or slab outline,
• parking or access areas.

7. Proposed Project Dimensions

Showing the proposed project without its dimensions may not give the reviewer enough information.

The plan should normally identify the overall size of the proposed work.

Depending on the project, this may include:

• structure length and width,
• deck or patio dimensions,
• pool and pool-deck dimensions,
• fence length and height,
• driveway width,
• gate width,
• equipment-pad size,
• roof or eave projections.

The dimensions on the site plan should be consistent with the permit application, floor plan, structural drawing, contractor proposal, and other submitted documents.

8. Setback Measurements

Setbacks are among the most important zoning details shown on a permit site plan.

A setback is generally the distance between a structure or improvement and a property line, street, building, easement, or other regulated feature.

The site plan may need to show distances to:

• front property line,
• rear property line,
• left side property line,
• right side property line,
• corner side or secondary street line,
• existing house,
• other accessory structures,
• easements or restricted areas.

Measurements should be taken from the point required by the jurisdiction. Depending on the project, that may be the wall, foundation, roof overhang, deck edge, stair, equipment pad, pool waterline, or another projecting element.

Missing or incorrectly measured setbacks are a common reason plans are returned for clarification.

For more information, read

Zoning Setbacks: What You Can Build and Where
.

9. Driveways, Access, Walkways, and Parking

Reviewers may also need to understand how people and vehicles enter, move through, and use the property.

Depending on the project, the site plan may need to show:

• existing driveway,
• proposed driveway or paved extension,
• driveway width,
• curb cut or street connection,
• sidewalk, curb, and gutter,
• alley access,
• walkways,
• parking spaces,
• turnaround areas,
• gates and access points.

This information is particularly important for garages, carports, ADUs, parking pads, and projects that change a driveway or access point.

Where paving will be widened, review the guide to

driveway-widening site plan requirements
.

10. Easements, Utilities, and Rights-of-Way

Known easements and utility constraints should be shown when relevant and available.

These may include:

• utility easements,
• drainage easements,
• access easements,
• sewer easements,
• rights-of-way,
• septic tanks and drain fields,
• wells,
• water or sewer service,
• gas or electrical equipment,
• overhead power lines,
• underground utility corridors.

A proposed project that appears to overlap an easement or utility area may require relocation, further documentation, or approval from another agency or utility provider.

Known easements should be based on available surveys, subdivision plats, title documents, recorded records, or other reliable property information.

Utility locations shown on a basic site plan may be approximate unless they have been professionally located or verified in the field.

A permit site plan does not replace underground utility marking before excavation begins.

11. Drainage, Grading, and Site Features

Some projects require important site features or drainage information to be shown.

Depending on the property and project, this may include:

• trees,
• retaining walls,
• fences,
• hardscape,
• landscaping areas,
• slopes or elevation changes,
• swales,
• drainage arrows,
• low points,
• stormwater facilities,
• floodplain or environmentally restricted areas.

Drainage information is particularly important for projects that add roofs, concrete, pavement, pools, patios, additions, or other impervious surfaces.

The reviewing authority may need to determine whether the project could block an existing drainage path, redirect water toward neighboring property, or increase lot coverage beyond local limits.

Projects involving

retaining walls

may also require wall-height, grading, drainage, and structural information beyond the basic site plan.

12. Existing, Proposed, and Demolition Labels

A reviewer should be able to distinguish existing conditions from proposed work immediately.

Use clear labels such as:

• Existing House,
• Existing Garage,
• Existing Driveway,
• Proposed Shed,
• Proposed Addition,
• Proposed Deck,
• Existing Fence to Remain,
• Structure to Be Removed.

Different line weights, shading, hatching, or line styles can also help distinguish existing and proposed features.

Do not rely on color alone, because permit plans may be printed or reviewed in black and white.

13. Title Block, Notes, and Revision Information

A permit-ready site plan should include basic drawing identification.

Depending on local requirements, the title block may include:

• project title,
• property address,
• owner or applicant name,
• drawing date,
• revision date,
• sheet title or number,
• drawing scale,
• notes or legend,
• drafter or preparer information where applicable.

This information helps reviewers identify the drawing and distinguish the current submission from older versions.

When a correction is issued, add revision information so everyone can confirm that the updated plan is the version being reviewed.

14. Readability and PDF Quality

Even a complete site plan can cause problems if it is difficult to read.

Before uploading the drawing, check for:

• cropped property lines,
• blurry text,
• small dimensions,
• overlapping labels,
• faint linework,
• incorrect page orientation,
• missing pages,
• low-resolution screenshots,
• notes hidden beneath other information.

The reviewer should be able to read the address, labels, dimensions, setbacks, notes, and project information without repeatedly zooming, rotating, or guessing.

A clean digital PDF is generally more useful than a poorly lit photograph of a sketch.

15. Consistency With the Permit Application

The site plan should match the permit application and other submitted drawings.

Check that:

• the project name is consistent,
• the proposed dimensions match,
• the structure location is the same on every drawing,
• the permit description matches the plan labels,
• the proposed driveway, deck, pool, shed, or addition has not changed between documents,
• the property address and owner information are correct.

Conflicting information creates immediate questions and may pause review until the documents are corrected.

Common Reasons Site Plans Get Delayed

Many site plan delays result from a familiar group of problems:

• missing or inaccurate property lines,
• missing setback measurements,
• unclear proposed work,
• existing structures omitted,
• project dimensions missing,
• driveways or streets not shown,
• known easements omitted,
• plans not drawn to scale,
• poor PDF quality,
• missing north arrow,
• existing and proposed work not distinguished,
• information that conflicts with the permit application.

What Reviewers Commonly Check Before Approval

Although every jurisdiction reviews permits differently, site-plan reviewers commonly begin with several core questions:

• Does the project fit within the property?
• Are the property lines and dimensions clear?
• Is the proposed work labelled clearly?
• Are the proposed project dimensions shown?
• Are the required setbacks identified?
• Are existing structures shown?
• Are driveways, access areas, and streets clear?
• Are known easements or restricted areas affected?
• Does the project create an obvious drainage or utility conflict?
• Does the site plan match the other application documents?
• Is the drawing complete and readable?

When those questions can be answered directly from the plan, the reviewer can move more efficiently through the remaining permit documents.

For deeper detail, see

What Reviewers Check First on a Site Plan
.

Site Plan Checklist by Project Type

Different projects require different site details. Common examples include:

• Shed permits: shed footprint, height, roof overhangs, foundation, setbacks, existing structures, and easements.
• Fence permits: fence route, height, material, gates, property lines, streets, driveways, and visibility areas.
• Pool permits: pool dimensions, deck area, setbacks, equipment pad, safety barrier, gates, utilities, easements, and drainage.
• Deck permits: deck footprint, stairs, landings, setbacks, height where relevant, and connection to the house.
• Driveway permits: existing and proposed paving, driveway width, access point, curb connection, right-of-way, and drainage.
• Garage permits: garage footprint, driveway access, setbacks, parking, roof overhangs, and separation from other structures.
• Home additions: proposed footprint, roof projections, setbacks, existing house, lot coverage, utilities, access, and drainage.
• ADU permits: proposed dwelling footprint, parking, access, setbacks, utility connections, and relationship to the main house.
• Retaining-wall permits: wall location, height, length, setbacks, grading, drainage, and nearby structures.

The more closely the drawing matches the project type and local permit checklist, the easier it is for the reviewer to understand the proposed work.

Can You Prepare Your Own Site Plan?

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

A homeowner-prepared plan may be accepted when it is:

• accurate,
• drawn to scale,
• clearly labelled,
• complete,
• based on reliable property information,
• consistent with the permit application.

Other jurisdictions may require a professional digital drawing, current survey, architectural plans, engineering, drainage documents, or other licensed work.

What to Provide When Ordering a Site Plan

Providing complete source information helps produce a clearer permit drawing.

Helpful items include:

• property address,
• project type and description,
• proposed project dimensions,
• preferred project location,
• survey or subdivision plat when available,
• parcel map or assessor information,
• photographs of the property,
• contractor drawings or sketches,
• measurements to property lines and structures,
• known easements and utilities,
• local permit checklist,
• correction notice if the project has already been reviewed.

The final permit requirements depend on the jurisdiction, property, and project. A site plan may be only one part of the complete application.

Final Thoughts

A clear site plan is one of the most important parts of many residential permit applications.

It helps reviewers understand the property, identify the proposed work, evaluate setbacks, and determine whether additional information or corrections are needed.

When the plan clearly shows property lines, existing structures, proposed work, dimensions, setbacks, access, known easements, and relevant site constraints, the review process is easier to follow.

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

The easier your site plan is to understand, the smoother the permit review process can be.
