- Residential Stock Plans

Residential Stock Plans for New Homes
When the same home design will be built at least three times with limited variations, a stock plan design or master plan can be submitted for a single review and then built multiple times and connected to a site specific permit.
For example: Imagine a grab-and-go style restaurant (where you place an order, take a number and find a table). The stock plan is like the menu, and the site specific permit is like you order and table number.
