Overview
Land use and zoning is a high-priority topic on the California Real Estate Salesperson Exam, covering how local, state, and federal governments regulate private property. This guide covers zoning classifications, government powers, the planning process, subdivision law, and development controls — all critical areas tested on the exam.

1. Zoning Basics
What Zoning Does
Zoning ordinances divide a municipality into districts and specify:
• Permitted land uses (residential, commercial, industrial)
• Building size and height limits
• Lot coverage and density
• Setbacks and yard requirements
Common Zoning Classifications
| Classification | Typical Uses |
|---|---|
| R-1 | Single-family residential |
| R-2 / R-3 | Multi-family (apartments, condos, duplexes) |
| C-1 / C-2 | Commercial (retail, office) |
| M-1 / M-2 | Industrial / Manufacturing |
| A-1 | Agricultural |
Key Concepts
• Spot Zoning — Rezoning a single parcel differently from surrounding land to benefit one owner. Generally disfavored and often ruled arbitrary or illegal because it conflicts with the general plan.
• Buffer Zone — A transitional area (open space, low-density land) placed between incompatible uses (e.g., industrial vs. residential) to reduce conflict.
• Setback Requirement — Minimum distance a structure must be located from a property line or street. Regulates front, side, and rear yards.
• Downzoning — Rezoning to a less intensive use (e.g., commercial → residential). Generally decreases property value by limiting profitable uses.
Key Terms
• Zoning Ordinance — Local law regulating land use within a jurisdiction
• Density — Number of dwelling units permitted per acre
• Lot Coverage — Maximum percentage of a lot that may be covered by structures
• Use Classification — The category of permitted activity on a parcel
> Watch Out For: Spot zoning questions often test whether the rezoning benefits one owner and conflicts with the general plan — both are red flags that make it illegal.

2. Zoning Variances & Exceptions
Variance
An official permission to deviate from zoning requirements. To obtain one, the property owner must prove:
1. Strict application causes undue hardship
2. The hardship is due to unique physical characteristics of the property
3. The hardship is not self-created
Two Types of Variances
| Type | What It Changes |
|---|---|
| Use Variance | Permits a land use not allowed in the zone |
| Area Variance | Permits relief from dimensional requirements (setbacks, height, lot coverage) without changing the permitted use |
Conditional Use Permit (CUP)
Allows a use not permitted by right under current zoning, but allowed with conditions imposed by the local planning authority to mitigate impacts.
• Examples: churches, schools, or gas stations in a residential zone
• Conditions might include landscaping buffers, traffic studies, or limited hours of operation
Nonconforming Use
A use or structure legally established before a zoning ordinance was enacted that no longer complies with current regulations.
Rules for nonconforming uses:
• Generally allowed to continue (protected as a vested right)
• Cannot be expanded
• If a nonconforming structure is destroyed by more than 50% of its value, it typically must be rebuilt to current zoning standards in most California jurisdictions
Key Terms
• Variance — Permission to deviate from zoning without changing the ordinance itself
• Conditional Use Permit (CUP) — Discretionary approval allowing a conditional use with restrictions
• Nonconforming Use — Legal pre-existing use that doesn't meet current zoning
• Vested Right — A property right established by prior lawful use
> Watch Out For: A variance requires unique hardship from the property itself — an owner wanting a different use for economic reasons alone does not qualify. Also distinguish a CUP (use allowed with conditions) from a variance (deviation from requirements).

3. General Plan & the Planning Process
The General Plan
A long-term, comprehensive policy document guiding a city or county's physical development.
• Required by California Government Code for every city and county
• Adopted by the local legislative body (city council or board of supervisors)
• Zoning ordinances must be consistent with the general plan — if they conflict, the general plan controls
The Seven Mandatory Elements (Memorize These!)
| Element | Focus |
|---|---|
| 1. Land Use | Distribution of land uses across the jurisdiction |
| 2. Circulation | Transportation systems, roads, transit |
| 3. Housing | Adequate housing for all income levels |
| 4. Conservation | Natural resources, watersheds, wildlife |
| 5. Open Space | Parks, recreation, agriculture |
| 6. Noise | Noise exposure and mitigation |
| 7. Safety | Seismic, flood, fire, and other hazards |
> Memory Tip: Use the acronym "LC-H CONS" — Land Use, Circulation, Housing, COnservation, Noise, Safety (open Space).
Environmental Impact Report (EIR)
• Required under the California Environmental Quality Act (CEQA)
• A detailed document analyzing significant environmental effects of a proposed project
• Required when a project may have a significant impact on the environment
• Purpose: Inform decision-makers and the public before approval
Key Terms
• General Plan — Comprehensive long-term land use policy document
• CEQA — California Environmental Quality Act; governs environmental review
• EIR — Environmental Impact Report; required for projects with significant environmental impact
• Consistency Requirement — Zoning must match the general plan
> Watch Out For: Zoning controls how land is used day-to-day; the general plan is the policy blueprint. Zoning must never conflict with the general plan — this is heavily tested.

4. Eminent Domain & Governmental Powers
The Four Government Powers Affecting Land Use (PETE)
| Power | Description |
|---|---|
| Police Power | Regulates use for public health, safety, welfare (zoning, building codes) — no compensation required |
| Eminent Domain | Takes private property for public use; just compensation required |
| Taxation | Property taxes; failure to pay can lead to government seizure |
| Escheat | Title reverts to the state if owner dies without heirs or a will |
> Memory Tip: PETE — Police Power, Eminent Domain, Taxation, Escheat.
Eminent Domain
• Government's power to take private property for public use
• Fifth Amendment (applied to states via the Fourteenth Amendment) requires just compensation (typically fair market value)
• The formal process of taking property is called condemnation
Inverse Condemnation
• Occurs when government action substantially damages or takes private property without formal condemnation proceedings
• The property owner initiates the legal action to compel just compensation
• Example: Government construction causes flooding on adjacent private land
Regulatory Taking
• Occurs when a regulation deprives the owner of all or substantially all economic use of the property
• Requires just compensation even without physical seizure
• Key test: Does the regulation go "too far"?
• Example: A zoning change that renders a parcel completely undevelopable
Key Terms
• Eminent Domain — Government's right to take private property for public use with compensation
• Condemnation — The formal legal process of exercising eminent domain
• Just Compensation — Fair market value paid to a property owner upon taking
• Inverse Condemnation — Owner-initiated action when government damages property without formal proceedings
• Regulatory Taking — Regulation so restrictive it effectively "takes" the property
> Watch Out For: Police power (zoning, building codes) requires no compensation. Eminent domain always requires just compensation. Regulatory takings are the gray area — compensation is owed only when the owner is deprived of all or substantially all economic use.

5. Subdivisions & Development Controls
California Subdivision Map Act
Governs the division of land into parcels for sale, lease, or financing.
| Number of Parcels | Required Map |
|---|---|
| 2–4 parcels | Parcel Map |
| 5 or more parcels | Tentative Map + Final Map |
• Applies to any division of land into 2 or more parcels
• Local government review ensures compliance with the general plan
Dedication
• The transfer of private land or improvements (streets, parks, utilities) to a public agency
• Required as a condition of subdivision approval
• Examples: Developer dedicates roads, sidewalks, or a park to the city
Planned Unit Development (PUD)
• Allows flexibility in design within a single development
• Permits a mix of land uses, varied lot sizes, and clustered buildings
• Overall density and design must meet zoning goals
• Encourages creative site planning not possible under standard zoning
• Common in master-planned communities
Downzoning Recap
• Rezoning to a less intensive use
• Generally reduces property value
• May constitute a regulatory taking if it eliminates all economic use
Key Terms
• Subdivision Map Act — California law governing land division
• Tentative Map — Preliminary map submitted for local government review (5+ parcels)
• Final Map — Recorded map following approval of tentative map
• Parcel Map — Simplified map for divisions of 2–4 parcels
• Dedication — Transfer of private land/improvements to public agency as condition of approval
• PUD — Planned Unit Development; flexible zoning for mixed-use or creative site design
• Setback — Minimum distance from property line to structure
> Watch Out For: The Subdivision Map Act triggers at 2 or more parcels — but the type of map required changes at 5 parcels. Many students confuse these thresholds. Also remember: a PUD is about design flexibility, not exemption from zoning rules.
