Michigan Site Plan Services for Permits and Property Projects

If you are planning a construction or improvement project in Michigan, your city, township, county, HOA, or building department may ask for a site plan before your permit can be approved.

A Michigan site plan is a clear overhead drawing that shows your property layout. It usually includes property lines, the existing house, driveways, proposed work, setback distances, easements, and other important site details.

Whether you are building a deck, adding a shed, installing a pool, expanding a driveway, building a garage, or planning a home addition, a site plan helps reviewers understand where the project will be located and whether it meets local requirements.

At USA Site Plans, we prepare clear, permit-ready site plans for homeowners, contractors, and property owners across Michigan.

What Is a Michigan Site Plan?

A site plan is a scaled drawing of your property from above. It shows existing structures and proposed improvements in relation to property boundaries, streets, driveways, setbacks, and other site features.

Michigan’s state building permit information explains that construction documents are generally required with each permit application, unless the building official determines that compliance can be confirmed from the application description. State of Michigan

For many residential projects, the site plan is one of the most important drawings because it helps the building department or zoning office confirm where the work will be placed on the lot.

A typical Michigan site plan may include:

property lines and lot dimensions;
existing house, garage, deck, shed, pool, or other structures;
proposed work such as a deck, pool, shed, garage, addition, or driveway;
front, side, and rear setback distances;
driveways, walkways, patios, and access points;
easements, utilities, or drainage areas if known;
north arrow and drawing scale;
labels showing what is existing and what is proposed.

Why Michigan Building Departments Ask for Site Plans

Michigan cities and townships use site plans to check whether a proposed project fits on the property and complies with local zoning, setback, and building rules.

The City of Ann Arbor explains that building permits are used to oversee and approve changes to structures, including demolition, renovation, installation, construction, augmentation, or other changes in the use of a building. City of Ann Arbor

Detroit also directs applicants to submit the appropriate required documents for permit and plan review through its Buildings, Safety Engineering, and Environmental Department. City of Detroit

A clear site plan helps reviewers check:

whether the project is inside the property lines;
whether the project meets setback requirements;
whether the proposed work conflicts with easements or utilities;
whether the project affects driveway access or parking;
whether the property already has other structures that matter for review;
whether the drawing gives enough information for zoning and permit approval.

Common Projects That May Need a Michigan Site Plan

Permit rules vary by city, township, and county, but many residential projects may require a site plan or plot plan as part of the application.

Common projects include:

decks and patios;
swimming pools;
sheds and accessory buildings;
garages and carports;
home additions;
driveway expansions;
fences and gates;
porches and covered entries;
demolition and replacement projects;
HOA or architectural review submissions.

Marquette County gives a simple example of what a plot plan may need to show before building. Its guidance says a plot plan should include the size and location of structures on the property, including distances to lot lines, streets, roads, and property lines. Marquette County

What Should Be Included on a Site Plan for Michigan?

A good Michigan site plan should be simple, organized, and easy for the reviewer to read. The goal is to make the project location clear.

Most residential site plans should show:

property address;
property boundaries;
lot dimensions;
existing house location;
existing garage, shed, deck, pool, patio, or other structures;
proposed project location;
project dimensions;
distance from proposed work to property lines;
distance from proposed work to nearby structures;
driveway and access areas;
easements or utility areas if known;
north arrow and scale;
basic notes or legend.

Washtenaw County states that site plans must be scaled at 1 inch equals 40 feet or larger for its plan review process. Washtenaw County

East Grand Rapids also gives a practical example for new construction and additions, stating that the site plan should show setbacks, dimensions, and the area of each component, including the lot and all existing and proposed structures. City of East Grand Rapids

Site Plan vs Plot Plan in Michigan

Some Michigan offices may use the term site plan, while others may use plot plan. For many residential permit applications, the terms are used in a similar way.

In simple terms:

A site plan usually shows the property layout and proposed work for permit or zoning review.
A plot plan often shows the lot, structures, setbacks, and distances to property lines.
A survey is usually prepared by a licensed surveyor and may be required when exact legal boundaries are needed.

If your project is close to a property line, located near an easement, or involves a legal boundary question, your municipality may ask for a survey or additional documentation. For simpler projects, a clear site plan may be enough.

Do You Need a Site Plan for a Deck in Michigan?

Many deck projects need a site plan because the building department may need to confirm the deck location, size, stairs, and setbacks.

A deck site plan should usually show:

the existing house;
the proposed deck footprint;
deck dimensions;
stairs and landings if included;
distance to side and rear property lines;
nearby structures such as fences, sheds, patios, pools, or garages.

Deck requirements can vary by municipality, so always check your local permit instructions before submitting.

Do You Need a Site Plan for a Shed or Accessory Building?

A site plan is commonly needed for sheds, detached garages, carports, and other accessory buildings because these structures affect lot layout, setbacks, and easement areas.

Grand Haven Township’s accessory building permit package states that for certain limited accessory building applications, only a site plan drawing is required, while regular building permit applications may require construction drawings and site plans reviewed for township ordinance and Michigan Residential Code compliance. Grand Haven Township

A shed or accessory building site plan should usually show:

the shed or accessory building location;
the size of the structure;
distance to side and rear lot lines;
distance to the house and other structures;
easements or utility areas if known;
driveway access if the structure is a garage or carport.

Do You Need a Site Plan for a Pool in Michigan?

Pool projects often require a site plan because the reviewer needs to understand where the pool will be placed and how it relates to the house, property lines, fences, and other structures.

A pool site plan may need to show:

pool location and dimensions;
distance from the pool to property lines;
pool equipment location if required;
fence or barrier location;
decking, patio, or paved areas;
nearby structures;
easements, septic systems, or utilities if applicable.

Pool rules can vary by city or township. If your property has a septic system, lakefront condition, easement, or unusual lot shape, extra information may be required.

Do You Need a Site Plan for a Home Addition or Garage?

Yes, in many cases. Additions and garages change the building footprint, so the reviewing office usually needs to confirm where the new construction will sit on the lot.

For example, the City of Sault Ste. Marie’s residential construction guide says that new homes, additions, decks or porches, renovation projects, and garage projects require a completed building permit application, site plan, and building plans submitted to the City Building Department. City of Sault Ste. Marie

An addition or garage site plan should show:

existing house footprint;
proposed addition or garage footprint;
overall project dimensions;
front, side, and rear setbacks;
driveway and parking areas;
other existing structures;
easements or right-of-way areas if known.

Why Site Plans Get Delayed or Rejected

Most site plan delays happen because the drawing does not clearly answer basic review questions. If the reviewer cannot confirm the property lines, setbacks, project size, or location, they may ask for corrections.

Common mistakes include:

missing property lines;
missing setback dimensions;
not showing the existing house;
not labeling the proposed work;
not showing the driveway or access route;
using a rough sketch that is not scaled;
forgetting easements or utilities;
measuring from a fence instead of the legal property line;
not showing other structures on the property.

A clean site plan helps prevent these issues by giving the building department a clear view of the property and proposed project.
