Differentiate Land Use Controls — Differentiate governmental powers and private land use restrictions. - National Real Estate Exam

SECTION 1

Historical Context & Motivation

The idea that a landowner possesses absolute dominion over property — the right to use it in any manner whatsoever — has never been fully realized in practice. Even under early English common law, courts recognized that one owner's use could harm a neighbor's quiet enjoyment, giving rise to the doctrine of nuisance. As American cities industrialized and populations concentrated, the tension between individual property rights and community welfare intensified, compelling both governments and private parties to develop formal mechanisms for controlling land use. These mechanisms evolved along two parallel tracks: public (governmental) controls rooted in sovereign authority, and private land use restrictions arising from voluntary agreements among property owners.

1916 • New York City Zoning Resolution

New York City adopts the nation's first comprehensive zoning ordinance, separating residential, commercial, and industrial districts to protect property values and public health.

1926 • Village of Euclid v. Ambler Realty Co.

The U.S. Supreme Court upholds municipal zoning as a valid exercise of police power, establishing the constitutional foundation for governmental land use regulation across the country.

1948 • Shelley v. Kraemer

The Supreme Court rules that racially restrictive covenants, while technically private agreements, cannot be enforced by courts because judicial enforcement constitutes state action violating the Fourteenth Amendment.

1978 • Penn Central v. New York City

The Court establishes the modern balancing test for regulatory takings, clarifying that government regulation of land use becomes unconstitutional when it goes 'too far' in diminishing property value without just compensation.

2005 • Kelo v. City of New London

The Court controversially upholds the use of eminent domain for economic development purposes, sparking nationwide legislative reforms limiting governmental taking authority.

This historical trajectory raises the central question for real estate professionals: How do governmental powers and private restrictions differ in their legal origins, scope, enforcement mechanisms, and durability? Mastering this distinction is essential for the National Real Estate Exam and, more broadly, for advising clients on the bundle of rights they actually acquire when purchasing property.

SECTION 2

Core Principles & Definitions

Land use controls divide into two fundamental categories based on their legal source. Governmental (public) land use controls derive from the sovereign powers of the state — police power, eminent domain, taxation, and escheat — and are imposed involuntarily on all property owners within a jurisdiction. Private land use restrictions originate from voluntary agreements between private parties, typically through deed covenants, conditions, restrictions (CC&Rs), or easements. While both categories limit how an owner may use property, they differ fundamentally in purpose, enforceability, and the remedies available when they are violated.

Police Power

The inherent authority of government to enact laws protecting public health, safety, morals, and general welfare. Zoning, building codes, and environmental regulations all stem from this power. No compensation is required unless the regulation constitutes a taking.

Eminent Domain

The government's power to take private property for public use upon payment of just compensation. The legal process is called condemnation. Unlike police power, eminent domain always requires the government to pay the owner fair market value.

Taxation & Escheat

Governments levy ad valorem property taxes and special assessments that create a lien on the property. Escheat allows the state to claim ownership of property when an owner dies intestate with no heirs, preventing land from becoming ownerless.

Deed Restrictions (CC&Rs)

Private covenants, conditions, and restrictions recorded in deeds or plat maps. These run with the land and bind future owners. Typical examples include minimum lot sizes, architectural standards, and limitations on commercial activity within a subdivision.

Easements & Equitable Servitudes

An easement grants a non-possessory right to use another's land for a specific purpose (e.g., a shared driveway). An equitable servitude is a promise about land use enforceable in equity even without privity of estate. Both are private, voluntary encumbrances.

✦

KEY TAKEAWAY

Think of governmental land use controls as the rules of the road set by the Department of Transportation — speed limits, traffic signals, lane markings — that apply to every driver regardless of consent. Private land use restrictions are more like the bylaws of a private country club: they apply only because the members voluntarily agreed to them when they joined, and enforcement comes from fellow members, not the police. The key mnemonic for the exam is PETE — Police power, Eminent domain, Taxation, and Escheat — representing the four governmental powers over real property.

SECTION 3

Visual Explanation — The Two Tracks of Land Use Control

The diagram contrasts the two tracks of land use control. On the left, governmental powers (remembered via the PETE mnemonic) operate involuntarily under sovereign authority. On the right, private restrictions originate from voluntary agreements and are enforced through civil litigation rather than governmental action. Note that governmental controls always supersede conflicting private restrictions.

The visual makes a critical distinction that appears frequently on the National Real Estate Exam: governmental controls are involuntary encumbrances that require no owner consent, whereas private restrictions are voluntary encumbrances that initially arise from the owner's own acts — recording a restrictive covenant, granting an easement, or purchasing property within a development governed by CC&Rs. However, once a private restriction 'runs with the land,' it binds subsequent purchasers who never personally consented, creating a practical similarity to governmental controls that can confuse exam candidates. The distinguishing factor remains the source of authority: sovereign power versus private contract.

SECTION 4

How Each Control Mechanism Works

Governmental Powers in Depth

Police power is the broadest governmental authority and the legal basis for zoning ordinances, building codes, health regulations, subdivision regulations, and environmental protection laws. When a municipality creates a zoning map dividing land into residential (R-1, R-2), commercial (C-1), and industrial (M-1) districts, it exercises police power. The constitutional test, established in Euclid v. Ambler (1926), asks whether the regulation bears a rational relationship to a legitimate governmental interest. Importantly, police power regulation does not require the government to compensate the property owner — unlike eminent domain — unless the regulation effectively deprives the owner of all economically beneficial use, which would constitute a regulatory taking under the Fifth Amendment.

Eminent domain operates through a formal legal proceeding called condemnation. The government must demonstrate that the taking serves a public use (or public purpose, post-Kelo) and must pay the owner just compensation, typically measured as the property's fair market value on the date of the taking. This is the only governmental power that constitutionally mandates payment to the owner. Inverse condemnation occurs when a government action effectively takes property without filing a formal condemnation proceeding, and the owner sues to recover compensation.

Taxation creates an automatic, superior lien on real property. Ad valorem taxes are based on the assessed value of the property, while special assessments are levied to fund specific local improvements (sidewalks, sewers) that directly benefit the property. Tax liens generally take priority over all other liens, including mortgages. Failure to pay property taxes can lead to a tax sale, in which the government sells the property to satisfy the outstanding tax obligation.

Private Restrictions in Depth

Private land use restrictions typically take three forms. Restrictive covenants are promises contained in deeds or recorded declarations that limit what owners may do with their property — for example, prohibiting commercial use in a residential subdivision or requiring homes to meet a minimum square footage. A condition is stronger: it specifies that ownership will revert to the grantor (or a designated third party) if the condition is violated, creating a defeasible fee estate. For a covenant to 'run with the land' and bind subsequent owners, courts historically require: (1) intent that it run, (2) touch and concern the land, (3) privity of estate, and (4) notice to the subsequent purchaser (constructive notice through recording satisfies this element).

Easements grant a non-possessory interest in another's land. The property benefiting from the easement is the dominant tenement, and the property burdened is the servient tenement. Easements may be created by express grant, implication, necessity, or prescription (similar to adverse possession). While not technically a 'restriction' in the same sense as a covenant, an easement limits the servient owner's use of the burdened area.

⚠

Conflict Rule

When a governmental regulation and a private restriction conflict, the more restrictive standard prevails — provided neither violates law. If zoning allows commercial use but a CC&R limits the parcel to residential use only, the CC&R controls because it imposes a tighter restriction. However, if a private covenant violates constitutional rights (e.g., racial discrimination), courts will not enforce it.

SECTION 5

Detailed Classification — Comparing Public and Private Controls

This composite diagram shows the spectrum of land use controls from the most coercive governmental powers (eminent domain) to voluntary private agreements, along with comparison dimensions and the hierarchy courts use to resolve conflicts. The more-restrictive-rule is a frequently tested concept: between a zoning ordinance and a private covenant, whichever imposes the tighter limitation on property use will control.

Dimension	Governmental Controls	Private Restrictions
Legal Source	Constitutional sovereign powers (police power, eminent domain, taxation, escheat)	Deed covenants, plat restrictions, private contracts, HOA declarations
Consent	Imposed unilaterally — owner consent is not required	Originally voluntary; subsequent purchasers bound if covenant runs with the land
Compensation	Only eminent domain requires just compensation; police power does not (absent a regulatory taking)	No compensation — parties voluntarily assumed restrictions
Enforcement	Government agencies, courts, fines, criminal penalties	Private lawsuit by affected owners or HOA; remedies include injunction or damages
Duration	Indefinite; changed only by legislative action or court ruling	May be time-limited, released by agreement, or abandoned; may expire or be deemed unenforceable
Scope	Applies to all property within the jurisdiction	Applies only to parcels whose chain of title includes the restriction

SECTION 6

Worked Example — Identifying and Resolving a Land Use Control Conflict

Consider the following fact pattern, representative of a common National Real Estate Exam question: Sarah purchases a parcel in Oak Ridge Estates, a planned subdivision. The subdivision's recorded CC&Rs limit all lots to single-family residential use with a maximum building height of 30 feet. The county zoning ordinance classifies the area as R-2 (residential, two-family), which permits single-family and duplex residences up to 35 feet in height. Sarah wants to build a duplex that is 32 feet tall. Can she do so?

Resolving a Zoning vs. CC&R Conflict

1
Step 1 — Identify All Applicable Controls

Two controls govern Sarah's property. The governmental control is the county R-2 zoning ordinance (permitting duplexes up to 35 feet). The private restriction is the recorded CC&R (limiting use to single-family and height to 30 feet).
2
Step 2 — Determine if the CC&R Is Valid and Enforceable

The CC&R was recorded in the chain of title before Sarah's purchase, providing constructive notice. It does not violate constitutional provisions or public policy (no discriminatory provisions). The restriction touches and concerns the land and was intended to run with the land.

The CC&R is valid and enforceable against Sarah.
3
Step 3 — Identify the Conflict

Zoning permits a duplex up to 35 feet; the CC&R limits use to single-family only and height to 30 feet. The CC&R is more restrictive on both dimensions — building type and height.
4
Step 4 — Apply the More-Restrictive Rule

When a valid private restriction is more restrictive than a governmental regulation, the private restriction prevails. The CC&R is not preempted by zoning because it does not contradict the zoning ordinance — it merely imposes additional limitations.

Sarah may NOT build a duplex and may NOT exceed 30 feet. The CC&R controls.
5
Step 5 — Consider Sarah's Options

Sarah could: (a) build a single-family home under 30 feet; (b) petition the HOA or lot owners to amend or release the CC&R (typically requires a supermajority vote per the declaration); or (c) argue in court that the restriction has been abandoned due to widespread non-enforcement, though this defense is difficult to establish.

SECTION 7

Strengths, Limitations, and Pitfalls

Control Type	Strengths	Limitations / Pitfalls
Zoning (Police Power)	Comprehensive, applies uniformly across districts; democratically enacted; protects community character and property values	Can be inflexible; variances and special use permits create exceptions; may constitute a regulatory taking if too burdensome
Eminent Domain	Enables essential public infrastructure (roads, schools); requires constitutional compensation	Potentially subject to abuse for economic development (post-Kelo); fair market value may not fully compensate owner for subjective value
CC&Rs / Deed Restrictions	Highly customizable; maintain neighborhood aesthetics and value; enforceable across owner generations	May become outdated; enforcement depends on private initiative (cost burden); courts may strike unreasonable restrictions; historically used for discriminatory purposes
Easements	Enable practical solutions (shared driveways, utility access); can be precisely tailored to need	May diminish servient property value; disputes over scope are common; prescriptive easements may arise without owner's knowledge

KEY TAKEAWAY

From a finance perspective, land use controls function like constraints on a portfolio's investable universe. Governmental regulations set the baseline 'regulatory floor' — analogous to SEC regulations that all market participants must follow — while private restrictions are like an investment fund's internal guidelines that further narrow permissible investments. A property's highest and best use analysis must account for both layers of constraints, because the effective restriction on the property is always the intersection (the tighter standard) of all applicable controls.

SECTION 8

Connections to Advanced Real Estate Concepts

The distinction between public and private land use controls connects directly to several advanced real estate concepts that appear on the National Real Estate Exam and in professional practice. Understanding these connections deepens your analytical framework and prepares you for exam questions that require synthesis across topics.

Foundational Concept	Advanced Extension	Connection
Police Power → Zoning	Nonconforming Use	A pre-existing use that does not conform to a new zoning ordinance is typically 'grandfathered in' but cannot be expanded. This illustrates police power's prospective nature.
Eminent Domain	Regulatory Taking (Inverse Condemnation)	When police power regulation goes 'too far,' it crosses into a taking requiring compensation — blending two governmental powers.
CC&Rs / Deed Restrictions	Equitable Servitude Doctrine	When traditional privity requirements for covenants running with the land are not met, equity may still enforce the restriction as an equitable servitude if the subsequent owner had notice.
Easements	Profit à Prendre	A profit is a type of easement that additionally allows the holder to remove resources (timber, minerals) from the servient land — a private restriction with economic extraction rights.
Conflict Resolution	Highest and Best Use Analysis	Appraisers must consider both public controls and private restrictions when determining a property's legally permissible uses — the first test in the highest and best use framework.

How foundational land use control concepts extend into advanced topics

For finance-oriented professionals, the most important advanced connection is to highest and best use analysis. In property valuation, the first criterion asks whether a proposed use is legally permissible — a determination that requires examining every layer of both governmental and private restrictions. A parcel zoned for commercial use but burdened by a residential-only CC&R cannot legally be developed for commercial purposes unless the CC&R is modified or released, directly affecting the property's estimated market value and investment return.

SECTION 9

Practice Problems

Question 1: CONCEPTUAL

A city passes an ordinance prohibiting the operation of auto body shops within 500 feet of a school. The city does not compensate any affected shop owners. Which governmental power is the city exercising, and why is compensation not required?

Show answer

The city is exercising its police power, which authorizes regulation to protect public health, safety, and welfare — in this case, protecting schoolchildren from noise, fumes, and hazardous materials. Compensation is not required under police power because the regulation does not physically take the property; it merely restricts its use for a legitimate public purpose. As long as the regulation does not deprive the owner of all economically beneficial use (a regulatory taking), the government need not pay compensation. The shop owners may still use their property for other lawful purposes permitted by the zoning ordinance.

Question 2: BASIC CALCULATION

A county assesses a residential property at $320,000. The local ad valorem tax rate (mill rate) is 28 mills. What is the annual property tax? If the owner fails to pay, what type of lien attaches to the property, and what is its priority relative to a first mortgage?

Show answer

Annual property tax = Assessed Value × Mill Rate = $320,000 × 0.028 = $8,960. (One mill equals $0.001, so 28 mills = $0.028 per dollar of assessed value.) The unpaid tax creates a tax lien, which is a governmental, involuntary, specific lien on the property. Tax liens generally take priority over all other liens, including a first mortgage. This superior priority reflects the government's taxation power, one of the four governmental controls (PETE).

Question 3: INTERMEDIATE

A developer records a subdivision plat with CC&Rs limiting lots to single-family residences with a minimum lot size of one acre. Ten years later, the county rezones the subdivision to R-3 (multi-family residential, minimum lot size 6,000 sq ft). A new lot buyer wants to build a fourplex. Analyze whether the buyer may proceed.

Show answer

The buyer may not proceed with a fourplex. Although the governmental zoning now permits multi-family development, the recorded CC&R is a valid private restriction that limits use to single-family residences with a minimum lot size of one acre. Under the more-restrictive rule, the CC&R controls because it imposes tighter limitations than the zoning ordinance. The CC&R was recorded before the buyer's purchase and provides constructive notice through the chain of title. Unless the CC&R has been released, amended by the required vote of lot owners, or successfully challenged as abandoned or unreasonable, the private restriction prevails over the less restrictive governmental zoning.

Question 4: APPLIED

You are a real estate analyst evaluating a commercial property for acquisition. The property is zoned C-2 (general commercial), but a title search reveals a deed restriction limiting the property to 'office and professional use only.' Your client wants to develop a retail shopping center. Explain how this affects your highest and best use analysis and your recommended due diligence steps.

Show answer

The deed restriction materially affects the legal permissibility prong of highest and best use analysis. Although zoning permits general commercial use (including retail), the private covenant restricts the property to office and professional use only. Under the more-restrictive rule, the deed restriction controls, meaning retail development is not legally permissible without removing the restriction. Recommended due diligence: (1) Determine who holds enforcement rights — the original grantor, adjacent lot owners, or an HOA; (2) Research whether the restriction has a stated expiration date; (3) Investigate whether surrounding properties have similar restrictions or whether widespread violations suggest abandonment; (4) Estimate the cost and probability of obtaining a release or court order extinguishing the restriction; (5) Model two scenarios — one assuming the restriction is lifted and one assuming it remains — to quantify the difference in property value and investment return.

Question 5: CRITICAL THINKING

A state government designates a privately owned historic building as a protected landmark, prohibiting any exterior modifications without approval from a preservation commission. The owner argues this constitutes a taking requiring just compensation under the Fifth Amendment. Analyze this claim, drawing on the distinction between police power and eminent domain, and discuss what factors a court would consider.

Show answer

This scenario sits at the intersection of police power and eminent domain — the regulatory taking doctrine. The landmark designation is an exercise of police power because it aims to preserve the public interest in historic resources. However, under Penn Central Transportation Co. v. New York City (1978), courts apply a multi-factor balancing test to determine whether a regulation has crossed the line into a compensable taking: (1) the economic impact of the regulation — does the owner retain reasonable economic use?; (2) the extent to which the regulation interferes with distinct investment-backed expectations — did the owner purchase knowing about the historic character?; and (3) the character of the government action — is it a physical invasion or merely a use restriction? If the building can still be used as offices, apartments, or retail, the owner likely retains economically viable use, and the designation would be upheld as valid police power regulation without compensation. Only if the regulation deprives the owner of essentially all economic benefit (per Lucas v. South Carolina Coastal Council, 1992) would it constitute a per se taking requiring just compensation.

SUMMARY

Summary

Land use controls divide into two fundamental categories. Governmental (public) controls — remembered through the PETE mnemonic (Police power, Eminent domain, Taxation, Escheat) — derive from sovereign authority, apply involuntarily to all owners within a jurisdiction, and are enforced by governmental agencies. Only eminent domain requires just compensation; police power regulation does not, unless it constitutes a regulatory taking.

Private land use restrictions — including deed covenants (CC&Rs), easements, and equitable servitudes — originate from voluntary agreements, are recorded in the chain of title, may run with the land to bind future owners, and are enforced through private civil litigation. When public and private controls conflict, the more restrictive standard prevails — provided the private restriction does not violate constitutional rights or public policy. This dual framework is essential for highest and best use analysis, title examination, and advising clients on what they can and cannot do with real property.
