Overview
Land use controls govern how private and public property may be used, developed, and regulated in New York. These controls fall into two broad categories: public controls (zoning, building codes, eminent domain, environmental regulations) and private controls (deed restrictions, restrictive covenants). Understanding how these systems interact is essential for the NY Real Estate Salesperson Exam.

Section 1: Zoning Fundamentals
What Is Zoning?
Zoning is a form of government police power that divides a municipality into districts and regulates land use within each district. The primary goals are to promote public health, safety, and general welfare by ensuring compatible land uses are grouped together.
Types of Zoning
| Zoning Type | Description |
|---|---|
| Euclidean Zoning | Most common; strictly separates uses into distinct districts (residential, commercial, industrial); upheld by U.S. Supreme Court in 1926 (Village of Euclid v. Ambler Realty) |
| Bulk Zoning | Controls the physical size and placement of structures: setbacks, maximum height, lot coverage, floor-area ratios |
| Cluster Zoning | Groups housing units at higher density on part of the land while preserving the remainder as open space; total unit count stays the same |
| Inclusionary Zoning | Requires a percentage of new units to be set aside as affordable housing for low- or moderate-income residents |
Nonconforming Use
• A nonconforming use legally existed before a zoning ordinance was enacted but does not comply with current regulations
• Generally allowed to continue (grandfathered in)
• Cannot be expanded or substantially changed
• May be phased out over time through amortization
Spot Zoning
• Spot zoning = rezoning a single parcel differently from surrounding properties to benefit one owner
• Generally illegal because it is arbitrary and inconsistent with the comprehensive (master) plan
• Courts look for whether the rezoning serves the public interest or only a private one
Key Terms – Zoning Fundamentals
• Zoning Ordinance – local law dividing a municipality into use districts
• Comprehensive Plan – the long-range land use policy document guiding zoning decisions
• Euclidean Zoning – strict separation of uses; named after Euclid, Ohio
• Bulk Zoning – regulates size and placement of structures
• Nonconforming Use – lawful pre-existing use that no longer complies
• Spot Zoning – illegal rezoning benefiting one owner
• Cluster Zoning – higher density on part of a site; open space preserved
• Floor-Area Ratio (FAR) – ratio of total building floor area to lot area
• Setback – minimum distance a structure must be from a property line
⚠️ Watch Out For
• Nonconforming use ≠ variance. A nonconforming use is a pre-existing legal right; a variance is a new permission granted by the ZBA.
• Euclidean zoning is named after a city (Euclid, Ohio), not the mathematician Euclid.
• Spot zoning is illegal because it violates the comprehensive plan, not simply because it differs from neighboring uses.

Section 2: Variances & Special Permits
The Zoning Board of Appeals (ZBA)
The Zoning Board of Appeals (ZBA) is the body in New York municipalities that:
• Hears and decides variance applications
• Interprets zoning ordinances
• Does not create new zoning laws (that is the legislative body's role)
Types of Variances
#### Area Variance
• Permits deviation from dimensional/physical requirements (setbacks, height, lot coverage)
• Lower burden of proof: applicant must show practical difficulties
#### Use Variance
• Allows a use otherwise prohibited in that zoning district
• Higher burden of proof: applicant must demonstrate unnecessary hardship
The "Unnecessary Hardship" Test (New York – Use Variance)
To obtain a use variance in New York, an owner must prove all four of the following:
1. The property cannot yield a reasonable return under current zoning
2. The hardship is unique to the property (not shared by the entire neighborhood)
3. The variance will not change the character of the neighborhood
4. The hardship was not self-created
Special Use Permit (Conditional Use Permit)
• Allows a use that is listed in the ordinance as permissible in a zone but only under specific conditions
• Example: a church, school, or day care in a residential zone
• Requires board approval to verify compatibility
• Not a variance — the use is allowed by right if conditions are met
Cluster Zoning Revisited
• Developer concentrates units on a portion of the land
• Remaining land preserved as open space
• Total number of units allowed does not increase
• Protects natural features (wetlands, forests, hillsides)
Key Terms – Variances & Special Permits
• ZBA (Zoning Board of Appeals) – hears variance and interpretation requests
• Area Variance – relief from dimensional requirements
• Use Variance – permission for a prohibited use; requires unnecessary hardship proof
• Unnecessary Hardship – standard for use variances in NY (four-part test)
• Special Use Permit – allows conditionally permitted use with board approval
• Conditional Use Permit – another name for a special use permit
⚠️ Watch Out For
• Area variance vs. use variance: Area = dimensions; Use = type of use. The hardship standard is stricter for use variances.
• A special use permit is not a variance — the use is already contemplated in the ordinance.
• The ZBA interprets zoning but does not write zoning ordinances.
• Self-created hardship defeats a use variance application.

Section 3: Eminent Domain & Government Powers
The Four Government Powers (PETE)
| Power | Description | Compensation? |
|---|---|---|
| Police Power | Zoning, building codes, health/safety regulations | None |
| Eminent Domain | Taking private property for public use | Yes – just compensation |
| Taxation | Property taxes, special assessments | None |
| Escheat | Property reverts to state when owner dies with no heirs/will | None |
> Memory Tip: PETE — Police power, Eminent domain, Taxation, Escheat
Eminent Domain
• Government's power to take private property for public use
• Constitutional requirement: The Fifth Amendment mandates just compensation (generally = fair market value)
• Applies to federal, state, and local governments
• Must be for public use (roads, schools, parks, utilities)
Condemnation
• The legal process by which the government exercises eminent domain
• Government initiates legal proceedings → court determines just compensation
• Owner may challenge adequacy of the compensation offered
Regulatory Taking
| Type | How It Occurs | Compensation Required? |
|---|---|---|
| Physical Taking | Government directly possesses/occupies property | Yes |
| Regulatory Taking | Regulation so severely restricts use that it deprives owner of all economic value | Yes |
• Key case concept: If a regulation leaves the property with no economically viable use, courts may find a compensable taking even without physical seizure.
Inclusionary Zoning (Police Power)
• Municipalities use police power to require developers to include affordable housing units in new developments
• A percentage of units must be set aside for low- or moderate-income residents
• No compensation paid to developer (it is a condition of approval)
Key Terms – Eminent Domain & Government Powers
• Police Power – government's inherent authority to regulate for public health, safety, welfare
• Eminent Domain – power to take private property for public use with just compensation
• Just Compensation – fair market value paid upon a government taking
• Condemnation – legal process of exercising eminent domain
• Regulatory Taking – regulation that effectively destroys all property value
• Escheat – property reverts to state; no will, no heirs
• Inclusionary Zoning – requiring affordable units in new developments
⚠️ Watch Out For
• Eminent domain is the power; condemnation is the process — don't confuse them.
• Just compensation = fair market value, not replacement cost or sentimental value.
• Taxation does not require compensation, even though the government is taking money from the owner.
• A regulatory taking can trigger compensation even if the government never physically sets foot on the property.

Section 4: Building Codes & Private Controls
Zoning Ordinances vs. Building Codes
| | Zoning Ordinances | Building Codes |
|---|---|---|
| Regulates | Use of land and buildings; placement on lot | Construction standards (structural, electrical, plumbing) |
| Purpose | Compatible land use and community planning | Safety and structural integrity |
| Type of Control | Public / governmental | Public / governmental |
| Enforced by | Local planning/zoning departments | Local building departments |
Certificate of Occupancy (CO)
• Issued by local government certifying a building complies with building codes and is safe to occupy
• Required before a new building or a significantly renovated structure can be legally occupied
• A CO may be required even for change of use in an existing building
Deed Restrictions (Restrictive Covenants)
• Private limitations placed in a deed by a grantor
• Run with the land — bind all future owners of the property
• Enforced by neighboring property owners through civil action (not by the government)
• Examples: prohibiting commercial use, requiring minimum house size, limiting fence height
Deed Restrictions vs. Zoning Laws
| | Deed Restrictions | Zoning Laws |
|---|---|---|
| Type | Private control | Public control |
| Created by | Grantor (seller/developer) | Government (legislature) |
| Enforced by | Neighboring property owners (civil suit) | Government agencies |
| Runs with land? | Yes | Yes (as long as ordinance exists) |
When Deed Restrictions and Zoning Conflict
> The more restrictive provision controls.
• If deed restriction is stricter than zoning → deed restriction governs
• If zoning is stricter than deed restriction → zoning governs
• Owner must comply with both
Key Terms – Building Codes & Private Controls
• Building Code – minimum construction standards for safety
• Certificate of Occupancy (CO) – proof building is code-compliant and safe to occupy
• Deed Restriction – private limitation in a deed running with the land
• Restrictive Covenant – another term for deed restriction
• Runs with the Land – obligation or right that passes to future owners
• Civil Action – private lawsuit used to enforce deed restrictions
⚠️ Watch Out For
• Deed restrictions are private — the government does NOT enforce them.
• An illegal deed restriction (e.g., based on race/religion) is unenforceable under the Fair Housing Act.
• A CO is not the same as a building permit — the permit is obtained before construction; the CO is issued after.
• When zoning and deed restrictions conflict, always apply the more restrictive rule.

Section 5: Environmental & Subdivision Controls
SEQRA – New York State Environmental Quality Review Act
• Requires state and local agencies to assess environmental impacts of proposed actions (including development) before approval
• If significant adverse impacts are identified → an Environmental Impact Statement (EIS) must be prepared
• Applies to governmental actions including permits, approvals, and direct projects
• Purpose: prevent environmental harm before it occurs (proactive, not reactive)
Subdivisions in New York
• Subdivision = division of a parcel into two or more lots for sale or development
• Developers must obtain Planning Board approval of a subdivision plat
• The approved plat is filed with the county clerk
• Planning Board reviews for compliance with zoning, infrastructure, environmental concerns
Subdivision Approval Process (General Steps)
1. Developer submits preliminary plat to Planning Board
2. Planning Board reviews; SEQRA review conducted
3. Final plat approved and signed
4. Plat filed/recorded with county clerk
5. Lots may then be sold
Buffer Zones
• A buffer zone is a neutral strip of land separating incompatible uses
• Examples: green space between industrial and residential areas; landscaping strips along highways
• Reduces negative impacts like noise, pollution, traffic, and visual blight
Key Terms – Environmental & Subdivision Controls
• SEQRA – NY State Environmental Quality Review Act; requires environmental impact assessment
• Environmental Impact Statement (EIS) – detailed analysis of significant environmental impacts
• Subdivision – division of land into two or more lots for sale/development
• Plat – a map/plan of a subdivision showing lot lines, streets, and dimensions
• Planning Board – local body approving subdivision plats and site plans
• Buffer Zone – neutral land area separating incompatible uses
• County Clerk – where approved subdivision plats are filed/recorded
⚠️ Watch Out For
• SEQRA applies to government approvals, not purely private transactions.
• An EIS is only required if significant adverse environmental impacts are identified — not automatically for every project.
• A plat is a map, not a deed — filing the plat does not transfer ownership of lots.
• The Planning Board handles subdivisions and site plans; the ZBA handles variances — these are different bodies.

Final Exam Tips
> 🔑 Remember PETE for the four government powers: Police power, Eminent domain, Taxation, Escheat
> 🔑 ZBA = Variances | Planning Board = Subdivisions & Site Plans — These are different bodies with different functions
> 🔑 More restrictive always wins when deed restrictions and zoning conflict
> 🔑 Condemnation is the process; eminent domain is the power — The exam loves to test this distinction
> 🔑 Nonconforming use ≠ illegal use — It was legal when it started; it just predates current zoning
