A scaled drawing is one that shows the object with accurate size reduction or enlargement by a certain amount and can be measured with a common architectural or engineer scale.
A common scale for floor plans is 1/4" = 1’-0” (one quarter inch is equal to one foot).
If you are hand drawing your plans, use graph paper to make it easier to draw to scale.
Graph paper comes in various sizes, including a size where each square measures 1/4" (one quarter inch), making it easy for each square to represent 1’-0” (one foot).
Our review staff uses both architectural and engineering scales for measuring plans to check they meet code requirements.
These scales are similar to rulers and can be purchased at office supply, hobby shops, and at some reprographic companies.
If staff cannot verify a measurement, this will lead to delays in the plan review process.
You can find websites and videos online to help you use and read an architectural or engineering scale.
