What Is Police power in Real Estate?
Police power is the government authority to regulate the use of private land to protect public health, safety and general welfare. Zoning, building codes and environmental rules all rest on it, and because the owner keeps title no compensation is owed.

1. Which of the following is NOT one of the four government powers over real estate?
Why: The four powers are Police power, Eminent domain, Taxation and Escheat (PETE). Novation is a contract concept — substituting a new party or agreement.
2. Zoning ordinances and building codes are exercises of which government power?
Why: Police power regulates land use to protect public health, safety and welfare, and requires no compensation because nothing is taken. Eminent domain takes property and must pay for it.
3. Recorded subdivision covenants limiting building height and exterior materials are:
Why: Recorded covenants, conditions, and restrictions are private encumbrances that bind every lot in the subdivision and pass to later buyers. Police power regulations such as zoning come from government rather than from a private declaration.
4. Zoning ordinances, building codes, and environmental regulations are exercises of:
Why: Police power allows government to regulate land use to protect public health, safety, and welfare without paying compensation. Eminent domain differs because it takes the property itself and requires just compensation.
5. A city adopts an ordinance limiting an entire district to single-family homes. Which governmental power authorizes that restriction on privately owned land?
Why: Zoning is an exercise of the police power, the authority to regulate land for public health, safety and general welfare, and owners are not paid for the limits imposed. Eminent domain is different because it acquires title or an interest and therefore requires just compensation.
6. A state acquires a 20-foot strip from the front yard of a home to widen a road, and the same owner is separately told a new ordinance bars building within 25 feet of the street. Which statement is accurate?
Why: Acquiring the strip is eminent domain, so the owner must be paid, while the setback is police power regulation that leaves the owner a use and pays nothing. Treating both as compensable ignores that ordinary land-use regulation is uncompensated.
7. A county amends its map so land that allowed 12 dwelling units per acre now allows only two. The amendment is best described as:
Why: Reducing the permitted intensity or density of development is downzoning, and it is generally valid police power even though land values may fall. Upzoning moves in the opposite direction by allowing more intensive development.
8. A developer offers to deed a park strip and cap building heights if the council will rezone a tract for apartments. An arrangement trading the map amendment for those promises is known as:
Why: Bargaining a rezoning in exchange for promises from the applicant is contract or conditional rezoning, which many courts restrict because a legislature may not sell its police power. Cumulative zoning merely describes districts that stack permitted uses.
