Heat Loss Calculations: The heat loss calculations are normally done by your lumber supplier, designer, or heating contractor. REScheck can be downloaded at www.energycodes.gov. Truss Plans including: truss layout and individual truss plans. These plans must be submitted prior to the rough fram- ing inspection and can be obtained by the truss manufacturer. Exterior Wall Bracing: Effective April 1, 2009, the State of Wisconsin Uniform Dwelling Code implemented new Wall Bracing re- quirements. Wall bracing had typically been accomplished by providing 4’ sections of wood structural panels at the corners of the building and spacing the wall panels within each wall section at intervals not to exceed 25’ on center. However, recognizing it may not be possible (or practical) to meet this requirement in all cases, the State Building Code now provides several alternative wall bracing methods. Continuously Sheathed Braced Wall Line Method: This is the most frequently used method when an addition has structural sheathing (OSB) applied to the entire surface of the exterior walls. Most lumber companies and/or designers can provide a wall bracing plan for you to submit when applying for a building permit. Nailing Requirements: When looking at nailing requirements the code requires that common nails be installed. Please refer to the charts below for the required spacing for alternate nails. The following can be substituted for 6d common nails: The following can be substituted for 8d common nails: NOTE: When nailing into treated plates make sure you are using nails that have been properly treated for use in those applications.

This also applies to penetrations of utility services through walls, floor and roof as- semblies, penetrations through the top and bottom plates. Sealing shall be provided at the attic and crawlspace panels, at recessed lights and around all plumbing, electrical and HVAC penetrations. The openings (used and unused) in the electrical boxes located in ceilings (attic areas) or exterior walls also need to be sealed. Smoke and CO alarms: A listed and labeled multiple-station smoke alarm with battery backup shall be installed in all of the following locations: Inside each sleeping room. On floor levels with one or more sleeping rooms smoke and CO alarms shall be installed outside of the rooms and within 21 feet from the centerline of any door opening to a sleeping room, and in the exit path from any sleeping room. On floor levels that do not contain a sleeping area, smoke and CO alarms shall be installed in a common area on each floor level. Smoke and CO alarms shall be continuously powered by the house electrical service and be interconnected. Permanent Weather Resistant Finish: The exterior walls of the addition are required to be covered with a permanent weather resistant finish. There is a misconception in the construction industry that vinyl siding is a permanent weather resistant finish. How- ever the vinyl siding does not protect the osb sheathing from getting wet and is actually constructed with holes in it to let the water shed out due to the fact that it is not weather resistant. Most vinyl siding manufac- turers require a weather barrier behind the siding such as tar paper or house wrap. Please also note that OSB is not an exterior finish material and it shall not be exposed to the elements for longer than required during con- struction even if it is painted. When installing house wrap and/or tar paper please remember to properly lap it so that the water sheds from the top of the structure to the bottom. General Installation Requirements: • Romex (type NM cable) shall be supported within 8 inches of a plastic box and 12 inches of a metal box and every 4-1/2 ft. thereafter (holes in studs are considered support). • Metallic boxes are to be grounded. • Mechanically secure all ground wire splices (green wire nuts, crimps, pigtails with wire nuts, etc.). • All devices are to be grounded, including switches, receptacles, light fixtures, etc. • All 120-volt, single phase, 15 & 20 ampere branch circuits supplying outlets installed in dwelling unit family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, or similar rooms or areas shall be protected by a listed arc-fault circuit interrupter (AFCI), combination-type, installed to provide protection of the branch circuit. Lighting: At least one wall switch-controlled lighting outlet is required in the following locations: • Every habitable room, bathroom, kitchen, etc. • Hallways and stairways (interior stairways require a switch at each floor level where the difference between floor levels is six steps or more). • Attached garages and detached garages with electric power. • Attic, under floor spaces, utility rooms, and basements shall have at least one lighting outlet containing a switch or controlled by a wall switch, at the usual point of entry, if these spaces are used for storage or contain equipment requiring servicing. • On the exterior side of exterior entrances and exits with grade access.
