2.3 Public Land Use Controls: Police Power, Master Planning, Zoning & Building Codes

Government Rights in Real Property: The PETE Framework

Although private ownership in the United States is rooted in the allodial system, fee simple absolute ownership is subject to four fundamental governmental powers, remembered by the acronym PETE:

1. Police Power: The inherent authority of the state (and municipalities via state enabling legislation) to enact, adopt, and enforce laws and ordinances to protect the public health, safety, morals, and general welfare of the community. Examples include zoning ordinances, building codes, environmental regulations, and subdivision controls.
2. Eminent Domain: The constitutional power of the government to take private real property for a public use or purpose upon payment of just compensation under the Fifth and Fourteenth Amendments of the U.S. Constitution and Article I, Paragraph 20 of the New Jersey State Constitution. The legal process of exercising this power is called condemnation.
3. Taxation: The sovereign authority to levy charges against real estate to fund municipal, county, and state government operations, education, and public infrastructure.
4. Escheat: The statutory reversion of real property to the state (in New Jersey, administered through the State Treasury) when an individual dies intestate (without a valid will) and without any legal heirs discoverable under statutory intestacy laws.

The New Jersey Municipal Land Use Law (MLUL)

In New Jersey, local municipalities possess no inherent constitutional authority to enact zoning or regulate land development. All municipal planning and zoning powers are strictly delegated by the state legislature through the New Jersey Municipal Land Use Law (MLUL, N.J.S.A. 40:55D-1 et seq.).

The Municipal Master Plan

The MLUL mandates that before any municipality can adopt or enforce a valid zoning ordinance, its Planning Board must prepare and adopt a comprehensive Master Plan. The Master Plan serves as the guiding policy blueprint for physical development, conservation, and capital improvement within the township or borough.

• Mandatory Elements: A master plan must contain, at a minimum, a statement of objectives, principles, and policies, a land use element, and a housing plan element that addresses low- and moderate-income housing obligations under New Jersey's landmark Mount Laurel doctrine.
• Periodic Re-examination: Under the MLUL, the municipal planning board must conduct a formal re-examination of the master plan at least once every 10 years (historically 6 years, amended to a 10-year cycle) and adopt a re-examination report identifying major development trends and necessary ordinance revisions.

Planning Board vs. Zoning Board of Adjustment (ZBA)

The MLUL creates a clear division of municipal administrative authority:

Zoning Classifications and Implementation

Zoning divides a municipality into geographical districts or zones, specifying permissible land uses, building heights, setbacks, and density limits. Standard zoning districts include:

• Residential (R): Single-family, two-family, and multi-family dwellings.
• Commercial (C): Retail, office buildings, restaurants, and shopping centers.
• Industrial (I): Light assembly, warehousing, and heavy manufacturing.
• Agricultural / Conservation (A): Farming, forestry, wetlands, and open space preservation.
• Planned Unit Development (PUD): Mixed-use zoning permitting residential, retail, and recreational uses in a unified, master-planned cluster development.

Key zoning metrics include setbacks (required minimum distances from property lines to buildings), buffer zones (landscaping strips separating incompatible uses, like industrial and residential zones), and Floor Area Ratio (FAR) (ratio of total building floor area to total lot square footage).

Nonconforming Uses

A legal nonconforming use (commonly called a "grandfathered" use) is a lawful use of land or a structure that existed legally before the enactment of a new or amended zoning ordinance, but which fails to conform to the new zoning regulations.

Under New Jersey law, property owners have a constitutional and statutory right to continue a legal nonconforming use, but that right is strictly constrained:

• No Expansion or Enlargement: The property owner cannot expand, intensify, or physically enlarge the nonconforming use without obtaining a use variance from the Zoning Board of Adjustment.
• Abandonment: If the owner voluntarily and intentionally ceases the nonconforming use for a sustained period, the grandfathered status is forfeited, and any future use must fully conform to current zoning.
• Destruction: Under New Jersey jurisprudence, if a nonconforming building is completely or substantially destroyed by fire, flood, or casualty, the owner cannot rebuild the nonconforming structure as of right; variance approval is required.

Variances under the MLUL: "C" Bulk vs. "D" Use Variances

A variance is administrative permission granted by a municipal board to depart from the strict literal requirements of a zoning ordinance.

1. "C" Variances: Bulk / Hardship Variances (N.J.S.A. 40:55D-70c)

Bulk variances apply to dimensional and physical zoning requirements (e.g., lot area, frontage, yard setbacks, building height, lot coverage):

• "C(1)" Hardship Variance: The applicant must prove exceptional physical hardship arising from exceptional narrowness, shallowness, or shape of the property, or from unique topographical conditions inherent to the land.
• "C(2)" Flexible Benefits Variance: The applicant demonstrates that granting the deviation advances the purposes of the MLUL and that the benefits of the deviation substantially outweigh any detriment.

2. "D" Variances: Use Variances (N.J.S.A. 40:55D-70d)

Use variances authorize a property use not permitted in the zoning district (e.g., operating a commercial veterinary hospital in a single-family residential zone) or allow substantial deviations in floor area ratio, density, or principal building height. Handled exclusively by the Zoning Board of Adjustment, an applicant must satisfy two demanding legal tests:

• Positive Criteria ("Special Reasons"): The applicant must prove that the site is particularly suited for the proposed use, that the proposal constitutes an "inherently beneficial use" (such as a school, hospital, or public utility), or that denying the variance would impose an undue hardship amounting to an unconstitutional confiscation.
• Negative Criteria: The applicant must prove that the variance can be granted without substantial detriment to the public good and without substantially impairing the intent and purpose of the zone plan and zoning ordinance.
• Supermajority Voting Requirement: Under N.J.S.A. 40:55D-70d, a "D" use variance requires an affirmative vote of at least five (5) members of a full seven-member Zoning Board of Adjustment (a statutory supermajority).

Building Codes and Certificates of Occupancy

While zoning dictates how land and buildings are used, building codes regulate how structures are constructed. New Jersey has adopted the New Jersey Uniform Construction Code (UCC, N.J.A.C. 5:23), establishing uniform technical standards for structural integrity, electrical wiring, plumbing, fire prevention, energy efficiency, and accessibility.

• Building Permits: Required prior to initiating any new construction, structural alteration, demolition, or substantial mechanical upgrade.
• Certificate of Occupancy (CO): Issued by the local construction code official upon successful final inspections, certifying that new construction complies with UCC standards and is safe for occupancy.
• Certificate of Continuing Occupancy (CCO): Many New Jersey municipalities require a CCO or municipal housing transfer certificate prior to the closing of title on resale homes, verifying that existing properties meet minimum local safety, fire, and maintenance standards.

Eminent Domain vs. Inverse Condemnation

• Eminent Domain: The direct, affirmative exercise of governmental power to condemn private property for public use upon payment of just compensation determined by fair market value appraisal.
• Inverse Condemnation (Regulatory Taking): A legal action initiated by a property owner against the government, claiming that a governmental regulation, zoning reclassification, or restriction is so excessively burdensome that it deprives the owner of all economically beneficial or productive use of the land, constituting a de facto taking without compensation under the Fifth Amendment.
