What Is Eminent Domain? When the Government Takes Your Property

7 min • Constitutional Law

Eminent domain is the inherent power of the government to take private property for public use, conditioned upon the payment of 'just compensation.' The power is rooted in the Fifth Amendment's Takings Clause, which states: 'nor shall private property be taken for public use, without just compensation.' This clause applies to the federal government directly and to state and local governments through the Fourteenth Amendment. Every state constitution also contains a takings clause. Eminent domain is not unlimited — the government must satisfy both the 'public use' requirement and the 'just compensation' requirement.

The 'public use' requirement was historically understood narrowly: the government could take land for roads, schools, courthouses, military bases, and other facilities owned and used by the public. However, the Supreme Court dramatically expanded the definition in Kelo v. City of New London, 545 U.S. 469 (2005), holding that 'public use' includes 'public purpose' — meaning the government can take private property and transfer it to private developers if the taking serves an economic development purpose (in Kelo, a Pfizer research facility and surrounding development). The Kelo decision was enormously controversial and prompted a backlash: 46 states passed laws restricting the use of eminent domain for economic development or private-to-private transfers. However, traditional public uses — infrastructure projects (highways, bridges, airports), public utilities (power lines, pipelines, water systems), and government buildings — remain the most common takings.

The 'just compensation' requirement means the government must pay the fair market value of the property taken — what a willing buyer would pay a willing seller in an arm's-length transaction. Fair market value is determined as of the date of the taking, considering the property's 'highest and best use' (not necessarily its current use). For example, if your residential property is zoned for commercial development and would be worth more as a commercial parcel, the government must pay based on the higher commercial value. If only part of your property is taken (a 'partial taking'), you're entitled to the value of the part taken plus 'severance damages' — the reduction in value to your remaining property caused by the taking (e.g., loss of access, reduced visibility, proximity to a highway).

Property owners have the right to challenge the government's valuation and demand a jury trial on the compensation amount. The process typically begins with the government making an offer based on its appraiser's valuation. The property owner should independently hire a qualified real estate appraiser with eminent domain experience — the government's initial offer is often below fair market value. If negotiations fail, the government files a condemnation lawsuit (an 'eminent domain proceeding'), and the court determines the compensation amount. The property owner can present evidence including: appraisals, comparable sales, expert testimony on highest and best use, and evidence of the property's income-generating potential. If the government's final offer is significantly less than the jury's award, most states require the government to pay the property owner's attorney's fees and expert costs.

Beyond direct physical takings, the government can also effect a 'regulatory taking' — where a regulation goes so far in restricting the use of property that it effectively takes the property without physically occupying it. The test comes from Penn Central Transportation Co. v. New York City, 438 U.S. 104 (1978), which established a three-factor balancing test: (1) the economic impact of the regulation on the claimant, (2) the extent to which the regulation interferes with distinct investment-backed expectations, and (3) the character of the government action. A total regulatory taking (where the regulation deprives the owner of all economically beneficial use) is a categorical taking under Lucas v. South Carolina Coastal Council, 505 U.S. 1003 (1992), requiring just compensation. Temporary takings, excessive permit conditions (under Nollan and Dolan), and physical invasion takings (even minimal — Loretto v. Teleprompter Manhattan CATV Corp., 458 U.S. 419 (1982)) also trigger the compensation requirement.

Key Takeaways

• The Fifth Amendment requires both 'public use' and 'just compensation' for any government taking of private property
• Kelo v. New London expanded 'public use' to include economic development — but 46 states have since restricted this through legislation
• Just compensation = fair market value based on highest and best use, including severance damages for partial takings
• Property owners can challenge the government's valuation and demand a jury trial; the government pays attorney's fees in many states if the award significantly exceeds the offer
• Regulatory takings — regulations that go too far — also require compensation under Penn Central and Lucas tests
