      Please save these files in your phone or computer so you can read or print them any time you want.

      Building codes

      These blueprints will meet building codes in most cases. But sometimes additional information is required that can usually be hand written on the blueprints with the guidance of your local building department staff.

      Most of the time just a few hand written changes or additions is all it takes to make the building department happy. They are usually pretty understanding with homeowners with little or no experience in the building permit process and will tell you exactly what they want in order to approve the plans.

      Additional Engineering

      If your building department requires engineering for the trusses or custom header that is typically built into the price of the trusses or header.

      Additional engineering might be required if you live in an area with extreme weather like lots of rain, snow, humidity, wind or seismic activity.

      Blueprint size and format

      The printed size of the blueprints are 36″x24″.

      Blueprints are in PDF format so you will have to print them out yourself. You can open them in a standard PDF reader and print them out in 8.5×11 size.

      But you will have to go to a print shop to have them printed out in full 36″x24″ size. Most print and blueprint shops can do this for about $1-$2 per copy. They can even re-scan them back into PDF format after you have marked them up to your specifications.
