Building Permit Plans (drawings) requirements for Residential differ from the requirements for Commercial projects. For each application the minimum number of printed sets is three (3). At this time we only accept printed versions. We expect as time goes by to begin accepting digital plans; however, we may still require the printed versions for file retention requirements. Plans that are inadequate may be rejected and be requested to be modified prior to the issuance of a permit. Plan accordingly to prevent delays in the plan review process.
Professional Design Requirements
Residential projects (single family and up to triplex) may or may not require professional engineering depending upon the project. Some complex residential projects may require professional structural design by persons licensed to practice in the State of Alaska. This is usually determined at the time of the application. Plans can generally be designed by the applicant however, there are several competent designers specializing in residential design located within the Kenai Peninsula Borough.
Commercial projects (including residential fourplex and greater) almost always require complete professional design by firms licensed to practice in the State of Alaska (AS 08.48). Minor commercial remodeling and some small commercial projects may be allowed without the need for professional design. Contact the Building Safety Department to discuss this prior to the application.
All wood frame truss designs must be submitted with your building permit. Often this is deferred after the permit has actually been issued. Before you order your trusses obtain the design sheets with engineering seals from the truss manufacturer and submit them. Make sure you request that the trusses be designed to handle all loads including the local 50 pounds per square foot roof snow load (70 pound ground snow load). All trusses require connections to resist uplift and movement (hurricane ties). Girder trusses must be designed to accommodate all loads. Girder hold downs need to be specified by the truss manufacturer to resist uplift and movement. Other trusses connecting to the girder may require additional hardware such as joist hangers and other attachment hardware.
Residential projects do not typically have many deferred submittals. The most common is the wood trusses. Truss design shall show all of the loads and be sealed by a professional engineer licensed to practice in the State of Alaska.
Commercial projects have many deferred submittals. Deferred submittals shall be sealed by a professional engineer licensed to practice in the State of Alaska. The most common submittals are the fire sprinkler systems, fire alarm systems, and kitchen exhaust hoods and their associated fire suppression systems.
