The city of Samva requires buildings constructed within the city walls to adhere both to certain building standards and to have been consecrated with at least one of the approved building enhancements: Fixity of the Earth, Commandment for the Preservation of All that Exists, Inhuman Strength, etc. — though unlike other cities that require consecration, Samva doesn't require that the casters be preapproved by the city.
More and more cities have instituted mandatory consecration as part of building codes. Both because the number of trained consecrators is higher than in the past, and because buildings are now becoming taller and cities denser, and any building collapsing or being on fire puts everyone else at risk.
Today, some of the buildings are collapsing and on fire.
