Overview

A four-page guide from the City of London's Building Division, Planning and Economic Development, on building permits for modular homes. It explains what a modular home is, then lists the items that accompany an application for a prefabricated modular home built off-site, for on-site installation, and for a CSA A277 modular home, including the Schedule 1 designer form, owner authorization letter, plot plan and drawings. It closes with additional resources and requirements, and is linked from the Additional Residential Units page.
