Permits and endorsements
What building, zoning, and sign permits do businesses need?
Before opening a physical location, a business typically needs zoning approval confirming the use is allowed at the address, a certificate of occupancy for the space, building permits for any construction or alteration, and a sign permit for exterior signage, all issued by the city or county building and planning departments.

Zoning clearance comes first
Every address sits in a zone that permits certain uses. Before signing a lease, confirm the intended use is allowed at that address, permitted outright, or only with a conditional use permit that takes a hearing. Many cities fold this check into the business license application as a zoning clearance step, and a license application can fail solely because the use does not fit the zone.
The certificate of occupancy
A certificate of occupancy certifies that a building or suite is safe and approved for a specific use and occupancy load. A change of use, retail to restaurant is the classic example, usually triggers a new certificate even without construction. Landlords sometimes hold a certificate for the shell only; the tenant's build-out gets its own.
Building permits and the inspection chain
Any structural, electrical, plumbing, or mechanical work in the build-out needs building permits, drawn plans, and inspections at defined stages, with a final inspection releasing the space for occupancy. Restaurants add health department plan review and fire department sign-off for hoods and suppression. The permit chain is sequential, and it is the timeline driver for most physical openings.
Sign permits are their own category
Exterior signage is regulated separately: size, height, illumination, and placement rules vary by zone, and most cities require a sign permit before installation, often filed by the sign contractor. Historic districts and planned developments add design review. Interior signs and window displays are usually exempt below size thresholds.
Where Cornerstone fits
These are local permits issued to the property owner, tenant, or contractor, and the filing runs through the local building department, typically handled by your contractor or architect. We flag them in this library because they gate the opening date, but we do not file them; our work is the state license stack that runs in parallel, covered in our business licensing service.
Frequently asked questions
Do I need a permit to open in a space the previous tenant used the same way?
Often the certificate of occupancy carries over for an identical use with no construction, but many cities still require a new business to confirm zoning and obtain its own certificate. Verify with the building department before assuming the paperwork transfers.
How long do building permits take?
Simple tenant improvements can clear plan review in days to weeks; full build-outs with health and fire review commonly run one to several months. The local review queue sets the pace, which is why experienced operators file early and stage the license stack around it.
Who files these permits, the business or the contractor?
Building and sign permits are usually pulled by the licensed contractor performing the work; zoning clearances and occupancy certificates are typically the tenant's or owner's application. Either way the obligation to have them rests with the business occupying the space.
