In order for the City to issue a permit to install a wider window or door in an existing opening you would need to provide a completed building permit application with a detailed plan.
The plan must indicate the following;
- Type, size and thickness of the header.
- The span of the new header and also the new opening for the new window or door.
- Indicate if the header will be supporting a floor and a roof, or just a roof, or just the gable end (with the height of the wall above it).
- If supporting a floor and a roof, what is the total span of the floor and the span of the complete roof; or
- If supporting just a roof, what is the span of the complete roof.
- The total weight that will be bearing on the new header will be carried down to the foundation. Please indicate how this will be accomplished.
Plans must be submitted with a completed building permit application.
