What constitutes a Vested Right in property development?

1. A developer's intention without any legal backing

2. An informal agreement with local authority

3. A developer having substantial investment and permits to develop

4. A property owner’s understanding of zoning laws

The correct answer is: A developer having substantial investment and permits to develop

A vested right in property development refers to the legal entitlement of a developer or property owner to proceed with a project or use the property in a certain way, based on certain established criteria. This typically includes having made a substantial investment in the project, which demonstrates a commitment to the development. Additionally, having the necessary permits is crucial, as these documents provide assurance that the proposed development complies with local laws and regulations. By obtaining permits and investing significant resources in the project, the developer essentially locks in their right to go forward with the development as planned, even if local regulations change after those rights have been established. This principle is designed to protect developers from retroactive enforcement of land use regulations that could invalidate or delay their plans after considerable resources have already been expended. The other options do not accurately represent the concept of vested rights. Intention without legal backing lacks the necessary foundation, an informal agreement is not sufficient to establish a vested right, and an understanding of zoning laws does not constitute a vested right unless it is coupled with formal approvals and substantial investments.
