They ARE, however, required to meet land use and zoning requirements.  \n• Building permits are required for all decks that are over 30”above grade at any point.  \n• Decks associated with new construction or modular homes do not need an additional permit provided:  \no Guardrails, handrails, and stairways meet code (see brochure Guardrails & Handrails)  \no All outside deck material is either pressure-treated wood or wood of natural resistance to decay (such as cedar or redwood)  \n• All covered decks need a permit. Before You Design Your Deck  \n• Check with Ketchikan Gateway Borough Planning & Zoning to find your property’s required setbacks. Setbacks from property lines vary depending on lot orientation to streets.  \n• If you live in Shoreline district area you will need to identify the exact location of the property’s septic system components including all drainfield reserve areas.  \nRequired Plan Information A Plans Examiner first reviews your plans and identifies potential problems.  \nIf the plans are incomplete or incorrect, the plans examiner will request additional corrected information. To help the project go smoothly, plans must be complete and show as much information as possible. See the examples below to create the plans and drawings for your project. Your project submittal MUST include:  \n• Permit application;  \n• Site plan;  \n• Floor Plan  \n• Deck cross-sections that show all sides and include structural details;  \n• Stair and railing details; and  \nIf the property is served by a well or onsite septic system, the plans must show that the deck will not encroach into the area served by the well and/or septic system.  \nBuilding Permit/ Plan Review Fees  \nBuilding permit / plan review fees are based on the project’s completed valuation (material and labor) . Incomplete submittals and reinspections may require additional fees.  \nCity of Ketchikan 1 of 8  \nMinimum Required Plan Details  \nRemember, the more information shown on the plans, the more likely your project will be successful. Draw your deck’s plans and details and submit two copies of the drawings. Plans do not need to be professionally drawn, but must include all of the information requested and be neat, legible, and drawn to scale.  \n1. Required Site Plan information (See Figure 1):  \n• Lot Dimensions;  \n• Location and size of existing structure(s);  \n• Location and size of the proposed structure;  \n• Setbacks from property lines of the existing and proposed structure(s) .  \nFigure 1: Site Plan  \n2. Required Floor Plan information (See Figure 2):  \n• Deck dimensions;  \n• Size and spacing of floor joists;  \n• Size of decking material;  \n• Size, location, and spacing of beams; and  \n• Type (both the grade and the species) of lumber  \nFigure 2: Floor Plan  \nCity of Ketchikan 2 of 8  \n3.
