Building permits are not the most exciting topic in home remodeling, but they might be the most important one you overlook. Permits exist to ensure your remodeling work meets safety codes, protects your family, and preserves the value of your home. Skipping them might seem like a way to save time and money, but the consequences can be severe and long-lasting.
This guide covers which projects require permits in Grand Rapids and the surrounding Kent County area, how the permit process works, what it costs, and why cutting corners on permits is never worth the risk.
Which Remodeling Projects Require a Permit?
The general rule in Grand Rapids and throughout Michigan is that any work involving structural changes, electrical modifications, plumbing alterations, or mechanical system changes requires a permit. Here is a detailed breakdown by project type.
Kitchen Remodeling
A kitchen remodel almost always requires at least one permit, and often multiple permits depending on the scope of work.
- Electrical permit required: Adding, moving, or modifying circuits. Installing new outlets, lighting fixtures, or appliance connections. Upgrading the electrical panel to support new appliances.
- Plumbing permit required: Moving the sink, adding a second sink (island prep sink), relocating the dishwasher, or adding a pot filler. Any modification to water supply or drain lines.
- Building permit required: Removing or modifying walls (especially load-bearing walls), adding or enlarging windows, changing the room's footprint, or adding a kitchen island that requires floor reinforcement.
- Mechanical permit required: Modifying HVAC ductwork, adding range hood venting to the exterior, or changing gas lines for a range or cooktop.
- No permit typically needed: Replacing countertops, installing new cabinets in the same configuration, replacing faucets or fixtures in the same location, painting, or replacing flooring (cosmetic work only).
Bathroom Remodeling
Bathroom remodels follow similar permit requirements to kitchens, with plumbing being the most common trigger.
- Plumbing permit required: Moving the toilet, relocating the shower or tub, adding a new shower where one did not exist, converting a tub to a walk-in shower if drain relocation is needed, and adding a bathroom to an existing space.
- Electrical permit required: Adding GFCI outlets, installing exhaust fans, adding heated flooring, or upgrading the lighting circuit.
- Building permit required: Moving or removing walls, enlarging the bathroom footprint, or modifying the floor structure for a curbless shower installation.
- No permit typically needed: Replacing tile, installing a new vanity in the same footprint, replacing a toilet in the same location, or updating fixtures without moving supply lines.
Home Additions
Home additions require the most comprehensive permitting of any remodeling project. You will need:
- Building permit for all structural work, foundation, framing, roofing, and exterior finish.
- Electrical permit for all wiring in the new space.
- Plumbing permit if the addition includes a bathroom, wet bar, or laundry.
- Mechanical permit for HVAC ductwork, equipment, and ventilation serving the new space.
- Zoning approval to confirm the addition complies with setback requirements, lot coverage limits, and height restrictions for your property.
Additions in Grand Rapids also require a site plan showing the proposed construction relative to property lines. The city enforces minimum setbacks: typically 25 feet from the front property line, 5 feet from side property lines, and 25 feet from the rear in residential zones, though these vary by zoning district.
Basement Finishing
Finishing a basement requires permits in Grand Rapids. The scope of permits depends on what you are adding, but at minimum you will need a building permit for framing and finishing the space.
- Building permit required: Framing walls, installing drywall, adding egress windows (required for any bedroom), and creating any habitable space.
- Electrical permit required: All new wiring, outlets, lighting, and circuits.
- Plumbing permit required: If adding a bathroom, wet bar, or laundry in the basement.
- Mechanical permit required: If extending HVAC to the basement or adding supplemental heating and cooling.
One critical requirement: any basement bedroom must have an egress window that meets code requirements for emergency escape. In Grand Rapids, this means a window opening of at least 5.7 square feet with a minimum width of 20 inches and a minimum height of 24 inches. The window sill cannot be more than 44 inches above the floor. A window well with a ladder or steps is required if the window is below grade.
Whole-Home Remodeling
A comprehensive whole-home remodel typically requires building, electrical, plumbing, and mechanical permits. When the scope of work is extensive enough, the city may require architectural drawings or engineered plans submitted with the permit application.
The Grand Rapids Permit Process Step by Step
Understanding the process helps set realistic expectations for your project timeline. Here is how it works when pulling permits in the City of Grand Rapids.
Step 1: Application Submission
The City of Grand Rapids accepts permit applications through their Community Development Department. Applications can be submitted online or in person at City Hall. The application requires a description of the work, the property address, the contractor's license information, and depending on the project scope, plans or drawings showing the proposed work.
Step 2: Plan Review
For straightforward projects like a bathroom remodel or kitchen renovation, plan review is typically completed within 5 to 10 business days. More complex projects involving structural modifications or additions may require 2 to 4 weeks for review. During this period, the plans examiner reviews your submission for compliance with the Michigan Residential Code, local zoning ordinances, and any applicable specialty codes.
If the reviewer identifies issues, they will issue corrections. Your contractor must address these and resubmit before the permit is issued. This back-and-forth can add time, which is why working with a contractor experienced in local code requirements matters.
Step 3: Permit Issuance
Once plans are approved, the permit is issued and posted at the job site. Work can begin. The permit is valid for 180 days in Grand Rapids. If work does not commence within that period, the permit expires and must be renewed.
Step 4: Inspections
This is where permits deliver their real value. At key stages during construction, a city inspector visits the job site to verify the work meets code. Common inspection points include:
- Foundation inspection (for additions) before concrete is poured
- Framing inspection after walls are framed but before drywall is installed
- Rough-in inspections for electrical, plumbing, and mechanical work before walls are closed
- Insulation inspection before drywall covers the insulation
- Final inspection after all work is complete
Each inspection must pass before the project proceeds to the next phase. If an inspector identifies a deficiency, the contractor must correct it and schedule a re-inspection. This process protects you as the homeowner by ensuring the work inside your walls meets safety standards before it is covered up and invisible.
Step 5: Certificate of Completion
After the final inspection passes, the city issues a certificate of completion (or occupancy, for additions). This document proves the work was done to code and is important for insurance, resale, and your own records.
Permit Costs in the Grand Rapids Area
Permit fees vary by municipality and project scope. At Thornapple Construction, we handle all permit applications as part of every project — permit fees are included in our proposal so there are no surprises. In general:
- Electrical, plumbing, and mechanical permits are each separate fees, typically modest in cost relative to the overall project.
- Building permits for remodels are calculated based on project valuation — larger projects incur higher fees.
- Building permits for additions are based on square footage and valuation, and are higher than remodel permits.
- Plan review fees are charged in addition to permit fees, typically calculated as a percentage of the permit fee.
Permit fees are a small fraction of any project budget and are well worth the protection they provide. Your Thornapple project manager will walk you through the expected permit costs for your specific project during the planning phase.
Permit Requirements by Municipality
If you live outside the City of Grand Rapids, your permits will be handled by your specific municipality or through the Kent County building department. Requirements are generally similar since all jurisdictions enforce the Michigan Residential Code, but there are differences in process, fees, and turnaround times.
Kent County
Unincorporated areas of Kent County are served by the Kent County Building Department. They handle permits for many of the townships surrounding Grand Rapids. The process is similar to the city, with applications, plan review, and inspections. Turnaround times are often slightly faster than the city due to lower volume.
East Grand Rapids
East Grand Rapids has its own building department and is known for thorough review, particularly for exterior changes. If your home is in the Wealthy Street Historic District or other designated areas, additional design review may be required for any visible exterior modifications.
Ada Township
Ada Township uses the Kent County Building Department for permitting. However, Ada has specific zoning requirements, including generous setback requirements in many areas and restrictions on lot coverage percentages. Verify zoning compliance before submitting permit applications.
Cascade Township
Cascade Township also uses Kent County for building permits. Be aware of Cascade's specific zoning districts and requirements, particularly if you are near the Thornapple River corridor where environmental regulations may apply.
Forest Hills / Grand Rapids Township
Grand Rapids Township (which includes much of the Forest Hills area) contracts with Kent County for building inspections. The township has its own zoning ordinance that governs setbacks, lot coverage, and land use.
Rockford
The City of Rockford has its own building department. If your home is in the historic downtown area, additional considerations may apply for exterior modifications. Contact the Rockford Building Department directly for specific requirements.
Byron Center / Byron Township
Byron Township uses Kent County for permitting services. Zoning requirements vary by district, so confirm your property's zoning classification before planning any additions or structures.
The Real Consequences of Skipping Permits
Some homeowners and contractors skip permits to save time and money. This is a serious mistake with consequences that can follow you for years.
Insurance Problems
If unpermitted work causes damage, such as an electrical fire from improperly wired circuits or water damage from incorrectly installed plumbing, your homeowner's insurance company can deny the claim. They may argue that the work was not done to code and therefore the damage was preventable. This can leave you personally responsible for the full cost of repairs — potentially a devastating financial exposure.
Selling Your Home Becomes Complicated
When you sell your home, the buyer's inspector, appraiser, or title company may discover unpermitted work. This can derail a sale entirely, force you to pay for permits and inspections retroactively, or require you to tear out and redo work that does not pass inspection. Unpermitted finished basements and additions are among the most common issues that surface during home sales in the Grand Rapids market.
Fines and Penalties
If the city discovers unpermitted work in progress or after the fact, they can issue stop-work orders, require you to obtain permits retroactively (often at double the normal fee), and impose fines. In some cases, they can require you to open up finished walls so inspectors can see the work that was covered without inspection.
Safety Risks
This is the most important reason permits exist. Inspections catch potentially dangerous conditions: overloaded electrical circuits, improperly supported beams, missing fire blocking, inadequate ventilation, and incorrect plumbing connections. These are not theoretical risks. They are the kinds of problems that cause house fires, structural failures, and water damage. The inspector is there to protect you and your family.

Frequently Asked Questions About Permits
Can I pull my own permits as a homeowner?
Yes. Michigan law allows homeowners to pull permits for work on their own primary residence. However, you become responsible for ensuring the work meets code and passes inspection. If you are hiring a contractor, they should be the one pulling the permit because it ties them to the work and makes them accountable for its quality.
How long does the permit process take?
For simple projects in Grand Rapids, expect 1 to 2 weeks from application to permit issuance. For complex projects requiring detailed plan review, allow 3 to 6 weeks. Your contractor should account for this in the project timeline.
Do I need a permit for replacing windows?
If you are replacing windows with the same size windows in the same openings, a permit is typically not required. However, if you are changing the size or location of a window, or adding a new window, a building permit is needed. Egress windows for basements always require a permit.
What about replacing a water heater or furnace?
Yes, permits are required for water heater and furnace replacements in Grand Rapids and most surrounding municipalities. These are mechanical and plumbing permits that ensure proper installation, venting, and gas connections.
Do cosmetic changes need permits?
Pure cosmetic work does not require permits. Painting, replacing flooring, installing new countertops, updating cabinet hardware, and similar surface-level changes are permit-free. The line is crossed when you start modifying the structure, electrical system, plumbing, or mechanical systems of the home.
The Bottom Line on Permits
Permits are not bureaucratic obstacles designed to slow down your project. They are a system of checks and verifications that ensure your remodeling work is safe, code-compliant, and built to last. The cost is minimal relative to your project budget. The time investment is manageable when properly planned. And the protection they provide, both during construction and for years afterward, is invaluable.
Any contractor who suggests skipping permits to save time or money is not looking out for your best interests. A reputable contractor views permits as a standard, non-negotiable part of the process.
