The Zoning System: Introduction
2.1. Introduction
🧭 Overview
🧠 One-sentence thesis
State zoning enabling acts empower municipalities to divide their territory into districts with different use, height, and area regulations to promote public health, safety, and general welfare, and these comprehensive zoning schemes—including the exclusion of commercial and industrial uses from residential districts—are constitutionally valid exercises of the police power.
📌 Key points (3–5)
- What zoning enabling acts grant: municipalities receive power to regulate building use, height, lot coverage, and population density by dividing territory into classified districts.
- How districts work: uses are typically cumulative (higher-numbered districts permit all uses from lower-numbered districts plus additional ones), and regulations must be uniform within each district class.
- Key procedural safeguards: public hearings, published notice, zoning commissions for recommendations, and boards of adjustment to hear appeals and grant variances in cases of practical difficulty or unnecessary hardship.
- Constitutional validity: the Supreme Court in Euclid v. Ambler Realty upheld comprehensive zoning, including the exclusion of apartments and businesses from single-family residential zones, as a valid exercise of police power with rational relation to public welfare.
- Common confusion: zoning is not a declaration that excluded uses are nuisances in themselves; rather, it is a territorial allocation plan to prevent congestion, disorder, and incompatible land uses that may harm residential character.
🏛️ Structure of zoning enabling acts
🏛️ Grant of power and purposes
Zoning enabling acts empower municipalities "to regulate and restrict the height, number of stories and size of buildings and other structures, the percentage of lot that may be occupied, the size of yards, courts, and other open spaces, the density of population and the location and use of buildings, structures and land."
- The power is granted "for the purpose of promoting health, safety, morals, or the general welfare of the community."
- Section 3 lists specific purposes: lessen street congestion, secure safety from fire and panic, promote health, provide adequate light and air, prevent overcrowding, avoid undue population concentration, and facilitate provision of infrastructure (transportation, water, sewerage, schools, parks).
- Regulations must be "made in accordance with a comprehensive plan" and consider "the character of the district and its peculiar suitability for particular uses."
🗺️ District classifications
The sample act divides the municipality into three types of overlapping districts:
| District type | What it regulates | Example classes |
|---|---|---|
| Use districts | What activities/buildings are allowed | U-1 (single-family only) through U-6 (industrial) |
| Height districts | Maximum building height | H-1 (2½ stories/35 feet) through H-3 |
| Area districts | Minimum lot sizes, yard setbacks | A-1 (5,000 sq ft interior lots) through A-4 |
- Cumulative structure: U-2 includes all U-1 uses plus two-family dwellings; U-3 includes U-1 and U-2 uses plus apartments, hotels, churches, schools; and so on.
- Don't confuse: a single parcel may fall under multiple overlapping district classifications (e.g., U-5 use + A-4 area + H-2 height).
📋 Procedural requirements
- Public hearings: no regulation or boundary becomes effective until after a public hearing with at least 15 days' published notice.
- Zoning commission: appointed to recommend district boundaries and regulations; must make a preliminary report and hold public hearings before submitting a final report.
- Supermajority for changes: if owners of 20% or more of affected area protest a proposed change, the amendment requires a three-fourths vote of the legislative body.
⚖️ Board of adjustment and variance power
⚖️ Composition and procedures
- Five members appointed for three-year terms, removable for cause after written charges and public hearing.
- All meetings open to the public; minutes and records are public documents.
- Appeals from administrative decisions must be filed within a reasonable time; filing an appeal stays enforcement unless the official certifies that a stay would cause "imminent peril to life or property."
🔧 Powers of the board
The board has three main functions:
- Hear appeals from administrative decisions alleged to be in error.
- Decide special exceptions as specified in the ordinance.
- Authorize variances "in specific cases of practical difficulty or unnecessary hardship" where literal enforcement would cause unnecessary hardship, "so that the spirit of the ordinance shall be observed and substantial justice done."
- Supermajority requirement: four of five board members must concur to reverse an administrative decision, grant a variance, or decide in favor of an applicant.
- Don't confuse: variances are not blanket permissions; they must be "in harmony with [the ordinance's] general purpose and intent" and granted only in specific cases.
🏛️ Judicial review
- Any aggrieved person, taxpayer, or municipal officer/department may petition a court of record within 30 days.
- The court may take evidence or appoint a referee; it may "reverse or affirm, wholly or partly, or may modify the decision."
- Costs are not allowed against the board unless it acted "with gross negligence, or in bad faith, or with malice."
🏛️ Constitutional validity: Euclid v. Ambler Realty
🏛️ The case and the ordinance
- Setting: Village of Euclid, Ohio (population 5,000–10,000, mostly farmland), a suburb of Cleveland, adopted a comprehensive zoning ordinance in 1922.
- Plaintiff's claim: Ambler Realty owned 68 acres zoned partly U-2 (two-family residential), partly U-3 (apartments/hotels/churches), and partly U-6 (industrial); it alleged the ordinance reduced the land's value from $10,000/acre (industrial) to $2,500/acre (residential) and constituted an unconstitutional deprivation of property without due process.
- Lower court: held the ordinance unconstitutional and enjoined enforcement.
⚖️ Supreme Court's reasoning
Justice Sutherland, writing for the Court, upheld the ordinance:
-
Police power evolves with conditions: "Building zone laws are of modern origin… with the great increase and concentration of population, problems have developed… which require additional restrictions in respect of the use and occupation of private lands in urban communities."
- Example: "Regulations… which are now uniformly sustained, a century ago… probably would have been rejected as arbitrary and oppressive."
- "While the meaning of constitutional guaranties never varies, the scope of their application must expand or contract to meet the new and different conditions."
-
Nuisance analogy: "A nuisance may be merely a right thing in the wrong place, like a pig in the parlor instead of the barnyard."
- The question is not whether a use is harmful in the abstract, but "considering it in connection with the circumstances and the locality."
-
Deference to legislative judgment: "If the validity of the legislative classification for zoning purposes be fairly debatable, the legislative judgment must be allowed to control."
🏘️ Rationale for residential-only districts
The Court summarized expert reports and state court decisions supporting the exclusion of businesses and apartments from single-family residential zones:
| Justification | How it promotes public welfare |
|---|---|
| Child safety | Separating dwellings from trade/industry reduces traffic, confusion, and street accidents |
| Fire protection | Easier to provide apparatus suitable to residential character; cheaper street paving without heavy trucks |
| Noise and disorder | Businesses are noisy, disturbing at night, invite loiterers; suppression of disorder is easier |
| Residential character | Apartments act as "parasites," interfering with light/air, monopolizing sun, bringing traffic and parked cars, ultimately destroying the detached-house character |
| Economic efficiency | Confining heavy traffic to business streets reduces street maintenance costs |
- Don't confuse: "The exclusion of places of business from residential districts is not a declaration that such places are nuisances… but it is a part of the general plan by which the city's territory is allotted to different uses."
🔍 Scope of the decision
- The Court emphasized it was ruling only on the ordinance's "general scope and dominant features," not scrutinizing every provision.
- "It is enough for us to determine… that the ordinance in its general scope and dominant features… is a valid exercise of authority, leaving other provisions to be dealt with as cases arise directly involving them."
- The Court acknowledged that "when… the provisions… come to be concretely applied to particular premises… some of them… may be found to be clearly arbitrary and unreasonable," but that was not the question before it.
🔧 Enforcement and remedies
🔧 Criminal and civil penalties
- Violations are declared misdemeanors; municipalities may provide punishment by fine or imprisonment or both.
- Municipalities are also empowered to provide civil penalties.
🚫 Injunctive relief
- In addition to penalties, municipalities may "institute any appropriate action or proceedings to prevent such unlawful erection, construction… to restrain, correct, or abate such violation, to prevent the occupancy of said building, structure, or land, or to prevent any illegal act, conduct, business, or use."
⚖️ Conflict with other laws
- Higher standard governs: wherever the zoning regulations require greater restrictions (e.g., larger yards, lower building height) than other statutes or ordinances, the zoning regulations govern; wherever other laws require greater restrictions, those laws govern.
- This ensures that the most protective standard applies in any given situation.
