Is it permissible to repartition an inheritance whose real estate assets—lands—have differed in value from what they were at the time of partition due to the issuance of laws that prohibited construction on them and designated them for agriculture only?

The heirs may re-divide the inheritance if they mutually agree to it. However, they are not compelled to nullify the initial division due to a change in the land's value after the division, because ownership has been established for each heir. A claim of unfairness in a voluntary division is not considered. The questioner is advised to refer to the Sharia court or trustworthy scholars for these matters.
