California Bar Takings
Last updated: May 2, 2026
Takings questions are one of the highest-leverage areas to study for the California Bar. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
Under the Fifth Amendment (applied to the states through the Fourteenth), the government may not take private property for public use without just compensation. A taking occurs in four principal ways: (1) a permanent physical occupation, however minor (Loretto); (2) a regulation that denies the owner all economically beneficial use of the land (Lucas); (3) a regulation that, under the multi-factor balancing test of Penn Central, goes 'too far' considering economic impact, interference with investment-backed expectations, and the character of the government action; and (4) an unconstitutional exaction — a permit condition that lacks an essential nexus (Nollan) and rough proportionality (Dolan) to the project's impact, including monetary exactions (Koontz). 'Public use' is read broadly to mean any rational public purpose, including economic development (Kelo).
Elements breakdown
Permanent Physical Occupation (Per Se Taking under Loretto)
Any permanent physical invasion authorized by the government is a per se taking, regardless of how minor the invasion or how great the public benefit.
- Government authorization of a physical invasion
- Invasion is permanent in character
- Invasion occupies private property
- Just compensation owed regardless of size or benefit
Common examples:
- Mandated installation of cable TV equipment on rooftops
- Required public access easement across private beach
- Forced installation of a utility box on private land
Total Regulatory Taking (Per Se Taking under Lucas)
A regulation that deprives the owner of all economically beneficial or productive use of land is a categorical taking unless background principles of state nuisance or property law already prohibited the use.
- Regulation eliminates all economically beneficial use
- Property retains essentially no productive value
- Use was not already barred by background nuisance/property law
- Just compensation owed unless background-principles defense applies
Common examples:
- Coastal-zone statute barring all building on a beachfront lot
- Wetlands rule prohibiting any development on entire parcel
Partial Regulatory Taking (Penn Central Balancing)
When a regulation diminishes value but does not deny all use, courts balance three factors to decide whether the regulation goes 'too far' and effects a taking.
- Economic impact of the regulation on the claimant
- Interference with distinct investment-backed expectations
- Character of the government action (physical-like vs. public program adjusting benefits and burdens)
Common examples:
- Landmark designation barring construction over historic terminal
- Height or setback rules that reduce but do not eliminate value
Unconstitutional Exaction (Nollan/Dolan/Koontz)
A permit condition that requires the owner to give up property or money is a taking unless it satisfies both an essential nexus and rough proportionality to the project's projected impact.
- Government conditions a land-use permit on a dedication or fee
- Essential nexus between condition and a legitimate state interest impacted by the project
- Rough proportionality between condition's scope and project's impact
- Applies to demands for property and to monetary exactions
Common examples:
- Beachfront permit conditioned on public-access easement
- Building permit conditioned on dedicating a bike-path easement
- Permit conditioned on payment toward off-site environmental mitigation
Public Use Requirement (Kelo)
The 'public use' element is satisfied by any taking rationally related to a conceivable public purpose, including economic redevelopment, even if the property is transferred to a private party.
- Government exercises eminent domain or effects a taking
- Taking is rationally related to a conceivable public purpose
- Public use includes public benefit/economic development
- California: Cal. Const. art. I, §19 mirrors federal rule but post-Kelo statutes restrict private-to-private transfers
Common examples:
- Condemnation for a comprehensive economic redevelopment plan
- Condemnation for a public road, park, or utility
Just Compensation
When a taking occurs, the government must pay the fair market value of the property taken at the time of the taking, measured by the loss to the owner, not the gain to the taker.
- Fair market value at the time of the taking
- Measured by loss to the owner
- Includes severance damages where partial taking diminishes remainder
- Temporary takings require compensation for the period of deprivation (First English)
Common examples:
- FMV of fee simple condemned for a highway
- Rental value of property during a moratorium later invalidated as a taking
Common patterns and traps
The Lucas Overreach
The fact pattern shows a regulation that significantly reduces a parcel's value, and a tempting answer choice invokes Lucas. But Lucas is reserved for the rare case where the owner is left with essentially zero economically beneficial use. If any productive use remains — farming, leasing, even a single buildable portion — Lucas is unavailable and the analysis must proceed under Penn Central.
A choice reading 'Yes, because the regulation eliminates the property's most profitable use' — confusing 'most profitable' with 'all economically beneficial.'
The Penn Central Default Win
When a regulation merely diminishes value, candidates often assume the owner wins because the loss is large. In practice, governments win most Penn Central cases because the character of the action is regulatory, not physical, and the owner often cannot show strong distinct investment-backed expectations — especially when the regulation was foreseeable when the property was acquired.
A choice reading 'Yes, because the regulation reduces the property's value by 80%' — a serious diminution that nonetheless typically does not amount to a taking under the three-factor balance.
The Forgotten Monetary Exaction
Pre-Koontz instincts treat money payments as different from land dedications. Koontz held that monetary exactions imposed as conditions on land-use permits are subject to Nollan/Dolan scrutiny. A permit condition demanding off-site mitigation fees must therefore satisfy essential nexus and rough proportionality.
A choice reading 'No, because Nollan and Dolan apply only to demands for real property, not money' — a stale rule rejected by Koontz.
The Public-Use Red Herring
Bar questions sometimes invite candidates to argue that a transfer to a private developer fails the 'public use' requirement. After Kelo, public use is a rational-basis inquiry satisfied by virtually any conceivable public purpose, including economic redevelopment. The real issue is almost always whether a taking occurred and what compensation is owed — not whether the use is public enough.
A choice reading 'No, because transferring the land to a private developer is not a public use' — wrong as a matter of federal constitutional law after Kelo.
The Background-Principles Escape
In a Lucas-style fact pattern, the government may avoid paying compensation by showing that the prohibited use was already barred by background principles of state nuisance or property law. Candidates miss this when the regulation merely codifies a longstanding common-law nuisance prohibition. No compensation is owed because the owner never had the right to engage in the prohibited use.
A choice reading 'No, because the owner never had the right under state nuisance law to engage in the prohibited activity' — the correct answer when background principles apply.
How it works
Start every takings problem by classifying the government action. If a permanent physical invasion is authorized — even a small cable box on a rooftop — stop: that is a Loretto per se taking and just compensation is owed. If instead a regulation merely restricts use, ask whether all economically beneficial use is gone; if so, Lucas controls and compensation is owed unless the use was already barred by state nuisance law. Most regulations do not wipe out all value, so you land in Penn Central, where you balance economic impact, interference with investment-backed expectations, and the character of the action. For permit conditions, switch to the Nollan/Dolan/Koontz exaction track and demand both essential nexus and rough proportionality. Finally, remember Kelo's broad reading of public use: the harder doctrinal fight is almost always 'is this a taking?' — not 'is the purpose public enough?'
Worked examples
Is Reyes likely to prevail on his takings claim?
- A No, because the equipment occupies a de minimis portion of the building and the public interest in broadband access is compelling.
- B No, because Reyes has not shown that the regulation deprives him of all economically beneficial use of the property under Lucas.
- C Yes, because the statute authorizes a permanent physical occupation of his property, which is a per se taking regardless of size or public benefit. ✓ Correct
- D Yes, because the regulation interferes with Reyes's distinct investment-backed expectations under the Penn Central balancing test.
Why C is correct: Under Loretto v. Teleprompter Manhattan CATV Corp., a permanent physical occupation authorized by the government is a per se taking entitling the owner to just compensation, no matter how minor the occupation or how weighty the public benefit. The state-mandated, permanent installation of broadband equipment on the building's exterior is exactly that kind of permanent physical occupation, so Reyes prevails on liability.
Why each wrong choice fails:
- A: Loretto expressly rejected size and public-benefit defenses to permanent physical occupations. The de minimis nature of the intrusion and the importance of the public interest do not defeat liability — they go only to the amount of compensation, which may be small. (The Public-Use Red Herring)
- B: Lucas governs regulatory takings that eliminate all economically beneficial use. This case is a physical occupation, not a use restriction, so the Loretto per se rule applies and there is no need to show total economic wipeout. (The Lucas Overreach)
- D: Penn Central balancing applies to regulatory takings that fall short of a per se rule. Once a permanent physical occupation is shown, courts do not balance — Loretto controls and the taking is established categorically. (The Penn Central Default Win)
Under what theory is Liu most likely to prevail?
- A Permanent physical occupation under Loretto, because the statute permanently prevents Liu from occupying the property with structures.
- B Total regulatory taking under Lucas, because the statute eliminates all economically beneficial use and no background nuisance principle bars the prohibited use. ✓ Correct
- C Partial regulatory taking under Penn Central, because the regulation diminishes the property's value by 95%.
- D Unconstitutional exaction under Nollan and Dolan, because the state demands that Liu surrender development rights without compensation.
Why B is correct: Lucas v. South Carolina Coastal Council recognizes a categorical taking when a regulation deprives an owner of all economically beneficial use of land, unless background principles of state nuisance or property law already prohibited the use. The statute here forbids essentially every productive use of Liu's parcel, leaving only token recreational possibilities, and the state has not shown that residential construction would have been a nuisance. That is the paradigmatic Lucas wipeout.
Why each wrong choice fails:
- A: Loretto requires a permanent physical occupation authorized by government, not merely a regulation prohibiting the owner from building. No third party is occupying Liu's land; the statute is a use restriction, which falls under Lucas or Penn Central.
- C: Penn Central applies when value is diminished but some meaningful economically beneficial use remains. Where, as here, all economically beneficial use is eliminated, Lucas's categorical rule applies and the candidate should not retreat to the harder-to-win three-factor balance. (The Penn Central Default Win)
- D: Nollan/Dolan exactions arise when the government conditions a discretionary land-use permit on a dedication or fee. The statute here is a generally applicable use prohibition, not a permit condition, so the exaction framework does not apply. (The Forgotten Monetary Exaction)
Will Patel likely prevail?
- A No, because monetary conditions on land-use permits are not subject to Nollan and Dolan, which apply only to demanded dedications of real property.
- B No, because the city's interest in mitigating traffic congestion is rationally related to a legitimate public purpose under Kelo.
- C Yes, because the city has not shown an essential nexus and rough proportionality between the $185,000 fee and the traffic impacts of Patel's specific project. ✓ Correct
- D Yes, because any permit condition that costs the applicant money is a per se taking under Loretto.
Why C is correct: Under Nollan, Dolan, and Koontz, a permit condition — including a monetary exaction — must bear an essential nexus to a legitimate state interest affected by the project and must be roughly proportional to the project's projected impact. The city has done neither: the fund targets a distant interchange unconnected to Patel's bookstore traffic, and there is no individualized determination tying the $185,000 to her project's impacts. The exaction therefore fails the Nollan/Dolan/Koontz test.
Why each wrong choice fails:
- A: Koontz v. St. Johns River Water Management District squarely held that monetary exactions imposed as conditions on land-use permits are subject to Nollan/Dolan scrutiny. This choice states a pre-Koontz rule that is no longer good law. (The Forgotten Monetary Exaction)
- B: Kelo's rational-basis 'public use' inquiry governs whether a taking is for a public purpose, not whether a permit condition satisfies the heightened nexus and proportionality requirements. Even a legitimate traffic-mitigation purpose cannot save an exaction that is not roughly proportional to the project's impacts. (The Public-Use Red Herring)
- D: Loretto's per se rule is reserved for permanent physical occupations of property, not monetary fees. Monetary exactions are evaluated under Nollan/Dolan/Koontz, which requires nexus and proportionality — not categorical invalidation.
Memory aid
PEN-LUCK: Physical (Loretto) → Economic-wipeout (Lucas) → Nexus/proportionality (Nollan-Dolan-Koontz) → Loss balancing (Penn Central) → Use is public (Kelo) → Compensation is FMV.
Key distinction
Lucas vs. Penn Central: Lucas applies ONLY when the regulation eliminates ALL economically beneficial use — essentially every dollar of productive value. If the parcel retains any meaningful use or value, you must run the three-factor Penn Central balancing test, where the owner usually loses absent strong investment-backed expectations.
Summary
Classify the government action first — physical invasion, total wipeout, partial regulation, or permit exaction — then apply the matching test; public use is rarely the live issue.
