Public and private land use controls
Distinguish government powers, planning rules, subdivision regulation, and private restrictions.
- Different authorities
- Local development approval, DRE offering regulation, environmental review, and enforceable private restrictions serve different purposes.
- Different relief
- A variance addresses qualifying property-specific restrictions; a conditional use permit addresses a conditionally authorized use.
- Different CEQA outcomes
- A negative declaration, mitigated negative declaration, and EIR reflect different environmental findings, not different grades of building permit.
Learning objectives
- Compare police power, eminent domain, taxation, and escheat.
- Distinguish general plans, zoning, variances, and conditional use permits.
- Apply public and private restrictions together without assuming either always overrides the other.
Ownership operates within a legal framework
Identify every independent source of a proposed-use restriction; fee-simple ownership does not eliminate public rules, private covenants, or physical constraints.
A buyer may own a parcel in fee simple and still be unable to construct the building desired. Land use can be limited by public law, a recorded private restriction, an easement, or the parcel's physical conditions. These are distinct sources of limits. A building permit does not ordinarily cancel an enforceable private covenant, and an association approval does not excuse violation of a public building code.
The central exam task is to identify the source of authority. Government regulation generally arises under public powers. Restrictions agreed to by private parties arise through deeds, declarations, covenants, and other enforceable instruments. Both can affect the same project.
Fictional workshop approval check
Assume these stipulated limits apply, the private restriction is enforceable, and no overriding law displaces it.
- Public height limit35 feet
The proposed 28-foot workshop clears this one public dimension.
- Recorded covenant24 feet
The same proposal exceeds this independently enforceable restriction by four feet.
- Proposed height28 feet
Passing 35 feet is not permission to ignore 24 feet.
- Changed factPrivate restriction is legally unenforceable
Now reassess the applicable obligations; the phrase stricter always wins is too absolute.
Identify which restrictions are valid and applicable before selecting the practical limiting result.
Four government powers
Distinguish government acquisition, regulation, revenue collection, and succession; the word condemnation can describe different processes depending on the facts.
Police power supports regulation for public health, safety, welfare, and related purposes. Zoning, building codes, and many safety regulations fit this category. It is broader than the work of a police department. A city imposing a lawful setback normally regulates the use of private property without purchasing the setback area.
Eminent domain is the power to acquire private property for public use subject to constitutional requirements, including just compensation. Condemnation is the legal process used to exercise that power. This meaning of condemnation differs from a building official declaring a structure unsafe, which is ordinarily a regulatory action.
An owner alleging that governmental conduct has taken or damaged property without the required compensation may bring an inverse condemnation claim. Not every reduction in property value caused by regulation qualifies as a compensable taking. The existence of a taking is a legal question requiring more than a comparison of before-and-after asking prices.
Taxation funds public functions. An ad valorem property tax relates to assessed value. A special assessment is associated with a specific improvement or benefit under governing law. These are not necessarily calculated on the same basis. California's assessment system and acquisition-value rules are addressed in the transfer and taxation material.
Escheat addresses property without a legally entitled owner or successor under applicable law. In the inheritance setting, property may eventually pass to the state when no qualified heirs or other successors exist. A person dying without a will does not automatically trigger escheat: intestate succession generally identifies heirs first.
Match the government action to its purpose
Imagine four notices concerning different properties. One announces acquisition of a strip for a public transit project. Another requires unsafe wiring to be corrected. A third imposes a lawful assessment for a particular improvement. A fourth concerns succession to property for which no legally entitled successor has been found.
The transit acquisition raises eminent-domain analysis, the wiring requirement illustrates police power, the improvement charge raises assessment rules, and the succession problem may ultimately involve escheat. A single word such as "government" does not distinguish them. Identify whether the government is acquiring, regulating, charging, or receiving property under succession law.
The word condemnation requires the same attention. In an eminent-domain question, it refers to the acquisition process. In a building-safety conversation, a statement that a house was condemned commonly concerns its unsafe condition. An exam stem describing compensation and public acquisition points toward eminent domain; a stem requiring repair of dangerous conditions points toward regulation.
The action and its purpose distinguish four commonly tested powers.
- Police powerpublic regulation
- Zoning and safety codes regulate use for public health, safety, and welfare.
- Eminent domainpublic acquisition
- Acquires private property for public use, subject to constitutional requirements.
- Taxationpublic revenue
- Property taxes and authorized assessments fund public functions or improvements.
- Escheatstate succession
- Can transfer property to the state when no legally entitled successor exists.
General plans, zoning, and building codes
General plans establish policy, zoning regulates development, and building codes address construction; satisfying one does not establish compliance with the others.
California cities and counties adopt general plans, long-term policy frameworks covering land use and required related subjects. These include housing, circulation, conservation, open space, noise, and safety, with additional requirements such as environmental justice where applicable. The general plan describes coordinated development policy rather than giving every owner an individual permit.
Zoning implements land use regulation through districts and standards. It can regulate use, density, height, setbacks, lot coverage, and other development characteristics. Density concerns units or intensity relative to land area. A setback keeps construction a specified distance from a boundary or other reference. Zoning permission alone does not establish compliance with fire, structural, access, utility, or subdivision rules.
Building codes address how structures are designed and built, including safety and habitability standards. A proposed use can comply with zoning while the proposed construction fails a building requirement. Conversely, a structurally sound building can house a use prohibited by zoning.
Rules vary by jurisdiction and can be altered by state housing law. An exam scenario normally supplies the applicable rule. In practice, verify the current rule with the appropriate agency rather than assume that a familiar city standard applies everywhere in California.
Read density and intensity as separate constraints
Assume a local rule allows four dwelling units per acre on a two-acre parcel. The simple density calculation gives eight units. That number is a ceiling under the stated density rule, not proof that eight units can be approved. Setbacks, parking, access, infrastructure, fire requirements, and other applicable standards may reduce the feasible plan.
Likewise, a height limit and a floor-area limit measure different things. A building may be below the allowed height but exceed the stated floor-area ratio. If an exercise specifies a floor-area ratio of 0.50 on a 20,000-square-foot lot, the allowed counted floor area is 10,000 square feet under that exercise's definitions. It is not automatically a 10,000-square-foot footprint on every floor.
These examples teach how restrictions operate together, not statewide density or floor-area standards. Actual local definitions determine which areas count, while state law may impose exceptions or override certain local limits. Use the assumptions given rather than importing a familiar city's rules into an unrelated problem.
Fictional development capacity worksheet
All figures are exercise assumptions. No state density bonus, exception, or other rule changes them.
- Counted site area3 acres
Use the area defined by the stipulated density rule, not an assumed buildable-area substitute.
- Density limit6 units per acre
3 x 6 gives an 18-unit ceiling under this rule alone.
- Independent infrastructure constraintCapacity for 12 units
Assume this is an applicable binding limit for the exercise.
- Combined ceilingAt most 12 units under these two limits
Satisfying the tighter number still does not prove every other approval requirement.
Eighteen is the density answer; twelve is the combined ceiling in the stated case. Neither is an approval certificate.
- 20,000-square-foot lot
- Assume counted lot area is 200 x 100 = 20,000 square feet and FAR is 0.50: 10,000 square feet of total counted floor area.
- 4,000-square-foot building footprint
- Each full story contains 80 x 50 = 4,000 counted square feet under the stated definitions.
Two full stories total 8,000 square feet; three total 12,000 and exceed the 10,000-square-foot FAR limit even with the same footprint.
Fictional project research register
The following agency records are stipulated examples, not an actual city determination.
- General-plan policyNeighborhood-serving development encouraged
A policy direction is not an issued permit for this specific shop.
- Zoning determinationProposed shop use permitted
This addresses the stated use; it does not certify the building design.
- Building reviewRequired fire-egress design unresolved
Use permission does not eliminate the separate construction issue.
The site may support the use in principle while the submitted construction still needs correction.
Relief and existing uses
Match the problem to a variance, conditional permission, or lawful nonconforming status; personal financial hardship does not establish a qualifying variance.
A variance provides relief from a zoning restriction because qualifying special circumstances of the property would otherwise deprive it of privileges enjoyed by similarly situated properties. Examples can involve unusual shape, topography, or location. It is not an automatic reward for financial hardship or personal preference. California's general variance statute does not allow a variance to authorize a use that the zoning regulation does not expressly authorize.
A conditional use permit allows a use already contemplated as conditional in the zoning system if required findings and conditions are met. A district might permit a certain facility only after review of traffic, hours, or compatibility. The permit is not the same as rewriting the entire zoning ordinance.
An issued permit remains subject to its enforceable conditions. Approval requiring a 9 p.m. closing time does not authorize midnight operation just because the facility's general use was approved.
A legal nonconforming use was lawful when established but no longer conforms after a regulatory change. It may continue within the governing limits, which can regulate expansion, abandonment, rebuilding, or termination. An originally illegal use does not become legal nonconforming merely through age. A salesperson should not promise unrestricted rebuilding of a nonconforming structure after a fire.
Compare three different approval paths
| Proposed situation | First concept to identify | Why the other labels can mislead |
|---|---|---|
| Unusual topography makes a standard setback unusually restrictive | Variance, if statutory findings can be met | A variance is not general permission for a prohibited use |
| Zoning allows a use only after specified compatibility findings | Conditional use permit | The use is already contemplated conditionally in the zoning framework |
| A once-lawful use predates a zoning change | Legal nonconforming use | Continued use may be limited, and the status is not created merely by age |
Suppose an owner wants to turn a residential garage into a retail shop, but the district does not authorize that use. Describing the request as a hardship variance does not make it valid under California's general variance statute. A different lawful authorization or change may be needed. The owner cannot establish the required property-specific findings merely by showing that the business could earn money.
A purchaser should also distinguish an approval already granted from an application or favorable informal conversation. Staff encouragement, a conceptual sketch, and an issued permit have different legal significance. An agent who describes an application as an approval changes the buyer's understanding of both risk and timeline.
What fact supports, or defeats, the proposed variance analysis under the ordinary California statute?
- Unusual terrain disadvantages this parcel
- Compare similarly zoned nearby properties and the effect of strict dimensional compliance.Potential variance analysis, if every required finding can actually be supported.
- A larger building would earn more rent
- No qualifying property-specific disparity is established.Profit preference alone does not supply the statutory findings.
- Retail use is not authorized by the zone
- The owner labels the prohibited-use request a variance.The ordinary variance statute does not authorize that use merely by changing the application label.
Use La Puente Municipal Code 10.60.020 as the identified local example. Assume continuing uses and no expansion, abandonment, or rebuilding issue.
- Before the zoning changeShop A lawfully established
Its required use approvals existed under the earlier rules.
- Same periodShop B opened unlawfully
Assume its use violated the governing rules and was never legalized.
- Rules changeCurrent rules do not allow either new shop
A's lawful prior status supports the local nonconforming route; B's mere age does not satisfy it.
The decisive changed fact is lawful establishment, not how old the storefront looks.
Subdivision and environmental review
Separate local subdivision approval from DRE offering requirements, and distinguish CEQA review outcomes without assuming every project needs an EIR.
The Subdivision Map Act primarily regulates the physical division of land through local government processes under state law, generally beginning with divisions into two or more parcels for the covered purposes.
The Subdivided Lands Law, administered by DRE, focuses on specified subdivision offerings and buyer protection, including public reports when required. Its general definition concerns five or more lots or parcels, but exemptions and special categories matter.
These baseline numbers do not answer every condominium, lease, or development case. A simple memory that both laws concern subdivisions must not erase their different purposes and administrators.
A DRE public report discloses material information about a covered subdivision. It is not a warranty of construction, a recommendation to invest, or a substitute for local approvals. Similarly, an approved map does not establish that every marketing claim has received DRE endorsement.
The California Environmental Quality Act, CEQA, requires public agencies to consider environmental effects of covered discretionary projects through the applicable review process. An environmental impact report is not required for every property sale or every permit; exemptions and other review outcomes exist. CEQA is a review and decision-making framework, while zoning determines authorized land uses. A project can raise issues under both.
Different environmental review outcomes
For a nonexempt covered project, a negative declaration reflects a finding that the project would not have a significant environmental effect under the applicable evidence standard. It does not mean the agency rejected the project.
A mitigated negative declaration addresses initially identified potential effects through qualifying revisions before public review, with no substantial evidence of a remaining significant effect. Where substantial evidence supports a possible significant effect under the governing standard, an environmental impact report is required. Public Resources Code section 21080 distinguishes these routes. The document choice does not replace separate land-use approvals or make the project exempt from enforceable private restrictions.
Assume the project is subject to CEQA and no exemption applies. What does the record establish?
- No substantial evidence of a possible significant effect
- Apply the governing whole-record standard.Negative-declaration route; negative does not mean the project was rejected.
- Qualifying revisions eliminate potential significant effects
- Required revisions precede public review, with no substantial evidence of a remaining significant effect.Mitigated-negative-declaration route under the stated conditions.
- Substantial evidence of a possible significant effect remains
- The applicable evidence standard is met; unsupported speculation alone is not the test.Prepare an environmental impact report.
- Ordinary four-lot division
- Assume an ordinary covered division for sale, with no exemption or special category.
- Being below the general five-lot Subdivided Lands Law threshold does not remove local Map Act analysis.
- Change the proposal to six lots
- The same physical-division inquiry remains.
- The general five-or-more offering threshold is now also implicated; check actual coverage and public-report requirements.
- Different work by different authorities
- Local division approval concerns the land-division process.
- DRE offering regulation and required buyer information are not construction warranties or investment endorsements.
Private controls
Apply valid public and private restrictions together while recognizing overriding law; the stricter apparent rule is not automatically legally enforceable.
Recorded CC&Rs can establish use restrictions, architectural review, maintenance duties, and assessment obligations in a development. A homeowners association administers powers granted by governing documents and law. The declaration, bylaws, operating rules, and public law have different roles and cannot be treated as one interchangeable document.
Where valid public and private restrictions differ, the owner ordinarily must satisfy both; the more restrictive practical result often controls. However, a private restriction that conflicts with overriding law may be unenforceable. Racially discriminatory covenants are not enforceable. Other statutes also limit private restrictions, so the phrase "the stricter rule always wins" is too absolute.
An injunction can order a person to stop or take certain action. It differs from a damages award compensating a loss. Enforcement rights and remedies depend on the restriction and law. A licensee should not advise a buyer that a restriction may be ignored because a neighbor appears to violate it.
Evaluate a proposed project in layers
A buyer plans six residential units on a parcel. The zoning appears to allow that use, but the site is part of a development with an architectural-review process and a recorded easement along one boundary. The buyer also intends to divide the property for separate sales. Each fact adds a distinct line of inquiry.
First, verify public use and development rules, including whether the proposed division requires local map approvals. Second, identify applicable DRE offering requirements. Third, read the private declaration and architectural process, recognizing that overriding statutes can limit private restrictions. Fourth, locate and interpret the easement because the building plan may interfere with its purpose. Approval on one layer does not automatically resolve the others.
If the buyer obtains a local building permit but proceeds in violation of an enforceable private covenant, the permit alone may not defeat private enforcement. Conversely, association approval does not authorize a public-code violation. The sound exam answer recognizes both sets of obligations without claiming that every private restriction necessarily remains enforceable forever.
The same reasoning limits what a disclosure document proves. A DRE public report helps buyers evaluate the covered offering but is not a construction warranty. An environmental report identifies and analyzes relevant effects but does not necessarily grant land-use entitlement. A title report addresses interests and exceptions rather than certifying a proposed building's code compliance. Identify the document's purpose before relying on it for a different question.
- Public controlsCheck applicable planning, zoning, building, and environmental rules.
- Private controlsCheck enforceable restrictions, easements, and association documents.
- Parcel feasibilityCheck physical access, utilities, soil, and the proposed design.
Worked scenario and exam review
Identify the proposed act and each necessary authority; a permit, public report, or environmental document answers only its own defined questions.
A buyer wants a 28-foot workshop. Local zoning allows 35 feet, while an enforceable recorded covenant allows only 24 feet. The zoning allowance does not authorize a covenant violation. If the buyer also needs relief from a side setback due to the parcel's unusual shape, that raises a separate variance question. Neither issue is answered by saying the buyer owns fee simple title.
Match police power to regulation, eminent domain to acquisition, taxation to revenue, and escheat to legally ownerless property. Separate a general plan from zoning, and zoning from construction standards. A variance, conditional use permit, and legal nonconforming use solve different problems. Always identify which authority must approve the proposed use and which independent restrictions still apply.
What does a mitigated negative declaration actually establish?
A buyer proposes a small development requiring discretionary local approval. Assume the project is not exempt from CEQA. An initial study identifies potentially significant effects. Before public review, the buyer agrees to revisions that avoid or reduce those effects below significance; the agency determines that no substantial evidence in the whole record indicates a remaining significant effect. Separate map approval and private architectural review are still pending.
An EIR is necessarily required because the first study identified potentially significant effects.
This answer freezes the analysis at the unrevised proposal. Public Resources Code section 21080 recognizes the negative-declaration route when the specified revision and evidence conditions are met. A potential effect in the initial study does not alone require ignoring qualifying mitigation.
A mitigated negative declaration may be appropriate, but it does not replace the other outstanding approvals.
The supplied facts track a mitigated negative declaration: agreed revisions address initially identified effects before review, and the remaining evidence supports no significant effect. The agency still must follow the applicable process; the result does not itself grant the buyer every development right.
The agreed mitigation makes the project ministerial, so CEQA no longer applies.
The question expressly supplies a covered discretionary project. Redesign can affect environmental impacts and the appropriate document without changing the nature of the agency's decision-making authority.
TakeawayName the environmental outcome from the findings, then keep it separate from the project's other approvals. CEQA exemptions and findings are fact-specific; neither an environmental document nor a DRE public report is a blanket project warranty.
Chapter sourcesExam pitfalls
A subdivision map and DRE public report are interchangeable.
The documents come from different regulatory functions and prove different things.
A negative declaration means the project was denied.
The label is an environmental determination, not a denial stamp.
A conditional use permit can authorize any profitable use.
Profitability does not expand the uses legally available through that procedure.
