Does Grandville have zoning, and what does it mean for a small home?

Grandville has its own zoning ordinance, so a parcel inside city limits must be evaluated under city rules.2 Grandville Community Development handles planning and zoning questions; ask the department to identify the parcel’s district before choosing a house design.5

Grandville permits accessory dwelling units in R1-A, R1-B and R1-C, subject to additional requirements, but does not permit them in R2-A under the residential use table.6 We could not confirm a separate tiny-home occupancy rule; ask Community Development about the proposed dwelling, lot dimensions and setbacks.5

Do you need a building permit in Grandville, and who issues it?

Grandville requires a building permit before excavation for construction, construction of a building, structure or parking area, or structural changes to an existing building.1 Grandville contracts building permits and inspections to Professional Code Inspections; contact PCI for building, electrical, mechanical, plumbing and sign inquiries.3

A Grandville building-permit application must demonstrate compliance with the zoning ordinance and building code.1 Grandville requires inspection and approval for occupancy before an altered, extended or newly erected structure is used.9 City Council sets required permit fees by resolution; ask PCI for the fee applicable to your proposed work.103

How do septic permits and well permits work inside Grandville?

For private sewage works where public sewer is unavailable, Grandville requires a permit signed by the City Manager, and Kent County Health Department also requires an onsite-sewage permit.4 Ask the city about sewer availability before planning a private system.4 A Kent County septic application for new construction must include a detailed site plan and floorplans.11

Grandville requires the permit holder to request inspection of underground sewage appurtenances before covering them.12 An onsite water-supply well installation in Grandville requires a Kent County Health Department permit.7 These health approvals are separate from the building permits and inspections handled by PCI.473

Can you live in an RV or tiny home on your Grandville land?

We could not confirm permission to occupy an RV or a tiny home on private land in Grandville; ask Community Development for a determination on the proposed use before relying on temporary housing during construction.5 Grandville’s prohibition on camping or sleeping on city-owned property and street rights-of-way does not establish a prohibition on all private-property camping.13

An accessory dwelling is a different zoning question: Grandville allows accessory dwelling units with additional requirements in specified single-family districts.6 A newly erected or altered Grandville structure must be inspected and approved for occupancy before use, so obtain that approval before moving into a proposed small dwelling.9

What are the steps before building a home in Grandville?

Start with Grandville Community Development: request the zoning district and review of the proposed residential use.5 Next, contact PCI about the building-permit application and the building, electrical, mechanical and plumbing work involved.3 Grandville requires building-code and zoning compliance in the application before construction begins.1

Where private sewage works are proposed, arrange city approval and Kent County Health Department septic approval; include the detailed site plan and floorplans for new construction.411 Obtain the county well permit if installing an onsite well.7 Finish with the required inspection and occupancy approval before using the home.9

What stays with Kent County, and what should you check before buying?

Kent County Health Department remains involved in Grandville onsite septic and well approvals, even though Grandville has city zoning and uses PCI for building permits.14723 Kent County septic permits and site evaluations are valid for 2 years and are non-transferrable; do not assume a seller’s approval transfers with the property.15

For applicable river, stream or drain floodplains, Michigan EGLE regulates development and prohibits new residential construction in the floodway.16 Ask Community Development about the parcel’s development constraints before committing to a design.5 For land outside Grandville, use the Kent County guide to understand the county’s separate health approvals and locally administered zoning.1718

Watch-outs

  • A Grandville building permit does not replace the city and county approvals required for private sewage works.4
  • Michigan’s owner-builder licensing exemption does not remove building-permit, inspection, zoning or utility requirements.8
  • We could not confirm private-land RV occupancy or tiny-home occupancy in Grandville; ask Community Development before planning to live onsite during construction.5
  • Kent County Health Department announces a convenience fee for credit and debit card transactions effective October 1, 2026; ask about payment options when applying for septic or well services.11
