What Is Zoning in Real Estate?

Every zoning question, answered

Every question above with its correct answer and the reasoning behind it. Read the explanations for the ones you answered correctly too. A lucky guess and knowing the rule look identical on a score report. These are sample questions from our larger bank.

1. 1. Zoning ordinances and building codes are exercises of which government power?

   • AEscheat
   • BTaxation
   • CEminent domain
   • DPolice powercorrect

   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.

   Land use controls

2. 2. Zoning allows a 35-foot building height, but the recorded CC&Rs for the subdivision limit height to 25 feet. What governs the lot?

   • AThe 35-foot zoning limit, because public law always preempts private agreements
   • BThe 25-foot restriction, because the stricter limitation controlscorrect
   • CNeither limit, because they conflict and cancel each other
   • DThe buyer may choose either limit at closing

   Why: Where a public regulation and a private covenant both apply, the owner must satisfy the stricter of the two, here the 25-foot covenant. Zoning states a maximum but does not release an owner from private restrictions.

   Property ownership

3. 3. Zoning ordinances, building codes, and environmental regulations are exercises of:

   • AThe power of taxation
   • BEminent domain
   • CPolice powercorrect
   • DEscheat

   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.

   Property ownership

4. 4. A buyer's contract made closing contingent on the buyer obtaining a zoning variance for a home office. The buyer never applied for the variance and then demanded a refund of the deposit. The seller's strongest response is that:

   • AThe zoning condition became an express warranty by the seller the moment the contract was signed
   • BThe variance requirement was a condition subsequent that had already lapsed
   • CZoning contingencies are unenforceable as a matter of public policy
   • DThe buyer breached the implied duty to make a good faith effort to satisfy the conditioncorrect

   Why: A party who controls a condition must try in good faith, so the buyer breached the implied duty to make a good faith effort to satisfy the condition. Claiming zoning contingencies are unenforceable as a matter of public policy is simply untrue; such contingencies are routine and enforceable.

   Contracts

5. 5. An owner argues a retail use is allowed because the comprehensive plan shows the area as commercial, although the zoning map still shows residential. Which is correct?

   • AThe zoning ordinance controls until it is amendedcorrect
   • BThe owner may build commercially and seek rezoning later
   • CThe plan controls because it is the higher authority
   • DThe more recently adopted document automatically controls

   Why: The zoning ordinance is the operative regulation, so the residential classification governs until the ordinance and map are amended. Treating the plan as controlling confuses long-range planning policy with enforceable regulation.

   Land use controls

6. 6. Under a cumulative or pyramidal zoning scheme, which of the following is permitted?

   • AA residential use is allowed in a commercial districtcorrect
   • BA commercial use is allowed in a residential district
   • CDistricts may be mixed only by variance
   • DEach district permits only the use for which it is named

   Why: Cumulative zoning stacks uses so that a district admits its own use plus every more restricted use above it, which is why housing may go into a commercial zone. Placing commercial activity in a residential zone reverses the pyramid and is not allowed.

   Land use controls

7. 7. The owner of a legally nonconforming duplex in a single-family district wants to add two more units. Most zoning ordinances treat that request as:

   • AAllowed only after the neighbors consent in writing
   • BAllowed, because grandfathered status covers later additions
   • CAllowed if the addition satisfies current setback rules
   • DNot allowed, since the use may not be enlargedcorrect

   Why: Nonconforming status protects the use only at the scale that existed when the ordinance changed, so enlargement is barred. Grandfathering freezes the use rather than approving every future expansion of it.

   Land use controls

8. 8. Which feature most distinguishes a planned unit development from conventional lot-by-lot zoning?

   • AEvery dwelling must satisfy the same setbacks as a detached house
   • BDensity is computed for the entire tract rather than lot by lotcorrect
   • CThe tract is exempt from building codes and permit review
   • DOnly industrial uses may be mixed within the boundary

   Why: A PUD approves one plan for the whole tract, so overall density governs and buildings may be clustered around shared open space with mixed housing types. A PUD never excuses the project from building codes or permits.
