Steps involved in the process

Mighty buildings will help you in every step of the process. They begin by running an initial compliance and feasibility check to evaluate the unique characteristics of your property as well as the regulatory requirements in your jurisdiction. Mighty Buildings then develop site-specific design documentation to apply for the permits. Once permits are approved, it will take approximately 30 days for their partners to prepare the yard for delivery and installation while they manufacture the unit in their facility. Lastly, they will ship the unit fully finished and ready to install with only minor on-site work.

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
