Loss of Access in California Eminent Domain

Access as a property right

An owner whose land abuts a public road has a right of reasonable access to it. That right is part of the property. Where a public project substantially impairs it, the loss can be compensable, either as severance damages in a condemnation case or as an inverse condemnation claim where no land is taken at all.

What a change in access looks like

• A driveway closed, narrowed or moved to a less useful position.
• A raised median that removes left turns into a site.
• A frontage road or a grade change that lengthens the approach.
• A signal or channelisation that makes entry difficult from one direction.
• Circuity of travel, where customers must now go a longer way round.

Where the line falls

Not every change is compensable. California distinguishes a substantial impairment of the right of access, which can be compensable, from a mere inconvenience or a diversion of traffic, which generally is not. The distinction turns on facts: what access remains, how it functions, and what the property needs.

Businesses that depend on approach

For a fuel station, a drive through, a motel or a retail site with impulse traffic, access is not a convenience but the business model. Where a change in access causes a loss of business goodwill, Code of Civil Procedure section 1263.510 may provide a separate route to compensation.
