Certificate of Occupancy
Definition
A certificate of occupancy (CO) is an official document issued by the local building department certifying that a building complies with building codes and is safe for occupancy. It is required before a building can be legally occupied.
Example
After completing construction of a new office building, the developer requests a final inspection. The building inspector verifies everything meets code and issues a certificate of occupancy. Only then can tenants move in and begin using the space.
Exam Tip
The CO comes AFTER construction is complete and final inspection is passed — not before. The exam tests the sequence: permit → construction → inspections → CO. Remember that a change in use (like converting a warehouse to apartments) also requires a new CO.

Zoning is the government's division of land into districts with specific permitted uses such as residential, commercial, industrial, or agricultural. It is the most common exercise of police power over private property.
Variance
A variance is an authorized deviation from the existing zoning ordinance granted to a property owner who demonstrates unique hardship. It allows a use or structure that would otherwise violate the current zoning rules.
Conditional Use Permit
A conditional use permit (also called a special use permit) allows a land use that is not automatically permitted by zoning but may be allowed under certain conditions. The use must be compatible with the surrounding area.
Nonconforming Use (Grandfathered)
A nonconforming use is a property use that was legally established before a zoning change but no longer complies with the current zoning ordinance. It is commonly called a "grandfathered" use.

Eminent domain is the government's constitutional right to take private property for public use, provided the owner receives just compensation. It is also known as condemnation.
