A local government permit that confirms a business can legally operate at a particular location under the applicable zoning rules.
A zoning permit (or zoning clearance) confirms that a business use is permitted in a specific location under local zoning laws. Local governments divide land into zones — commercial, residential, industrial, mixed-use — and specify what types of businesses can operate in each zone. Running a business in a zone that doesn't permit your use can result in fines, forced closure, or loss of business licenses.
Home-based businesses are subject to zoning rules too. Many residential zones allow limited business activity (a professional working from a home office) but prohibit retail traffic, employees coming to your home, or commercial signage. Operating a daycare, salon, or manufacturing operation from a residentially zoned home is often restricted or requires a special use permit.
If you're signing a commercial lease or purchasing property for a business, verify the zoning before committing. Check with your local planning department — most jurisdictions have online zoning maps. For certain business types (childcare, food service, retail), you may need specific zoning clearance as part of the licensing process.
