The one-half hour seminar in module 2 that follows, will complete the remainder of chapter 3, building planning, already begun in module 1. 1
This new alternative testing standard for safety glazing, can be used for testing glazing to be placed in locations not required by the federal standard. Typically the consumer product safety commission standard is used for safety glazing in doors and shower enclosures, while this new standard can test safety glazing that will be used in other locations as shown on the following slide. 2
Safety glazing must be identified including which of the testing standards was met. 3
Requirements for safety glazing at hazardous locations subject to human impact have been reorganized in an easy to use format. 4
A new exception has been added to the safety glazing section to indicate that a window panel adjacent to the fixed panel of patio doors does not require safety glazing. 5
Every sleeping room shall have at least one operable emergency escape and rescue opening, including sleeping rooms in basements and habitable attics. Such openings are not required in basements or habitable attics that are not sleeping rooms. 6
The IRC requirement for emergency and rescue openings in basements and has been limited to only those spaces containing sleeping rooms. 7
Replacement windows in existing buildings are not required to comply with the minimum size requirements of the emergency escape and rescue code section. 8
The section for the egress door has been revised to identify that the means of egress ends when the occupant reaches grade at the exterior of the building. There are no requirements beyond that point. Door measurements are shown on next slide. 9
The door width is determined as shown when the door is open to the ninety degree position and the height of the door is from the top of the threshhold to the bottom of the upper stop. 10
Every garage must now have at least one side-hinged door that is at least two feet six inches wide and Six feet eight inches high. An attached garage may use a door directly between the garage and the dwelling for this access door. 11
All finished levels in every dwelling shall have an egress door or they shall be served by a ramp or a stairway that meets the requirements of the code for an egress ramp or stairway. 12
Changes have been made to treads and risers not to their dimensions, but to how those measurements are made. Please note that while carpets are deleted, tile and other permanent coverings must be accounted for. Dimensions are depicted on the next slide. 13
It is not the intent of the code to require carpet or to regulate carpets, so the measurements for the treads and risers are taken without carpets, rugs or runners. 14
In order to maintain the required continuity in handrails at the upper and lower ends, a transition is normal, but the transition may exceed the maximum handrail height. This deviation is now permitted by an exception. 15
The new exception permits the transition fittings used for continuity or terminations of handrails to exceed the maximum handrail height of 38 inches. 16
The methods of measuring distance to grade to determine the necessity for guards in shown on the next slide. While insect screening is not considered a guard, an exception states that a guard is not required when a protective bar is installed on the interior side of porch or deck screening. 17
When determining the need for a guard, the vertical distance from the walking surface to the grade or floor is measured to the lowest point within 36 inches as shown. 18
When determining the maximum height of a guard, fixed seating is considered to be the same as a walking surface, and the height is measured from the seat to the top of the guard, as shown. 19
While sprinkler systems are not required, the code contains requirements for sprinkler systems in the event the owner elects to install. In addition to following NFPA 13, OR 13-R OR 13-D, chapter 29 of the plumbing code also contains code requirements that may be followed for voluntary sprinkler installations. 20
The smoke alarm section has been reorganized creating a new subsection for all power requirements and adds the habitable attic as a location that must have a smoke alarm. 21
If a dwelling contains fuel-fired appliances or has an attached garage, carbon monoxide detectors are required for all new construction outside each sleeping area. In existing dwellings, whenever work requiring a permit takes place, carbon monoxide detectors shall be provided. 22
Carbon monoxide detector devices are to comply with UL 2034 and installation shall be in accordance with the manufacturer s recommendations. 23
Carbon monoxide detectors are to be installed in the areas outside of and adjacent to bedrooms. They are to be provided any time there is work requiring any permit. 24
New item 5 requires protection of wood if minimum clearances are not maintained. (see following slide) 25
Exterior wood siding including wood structural panel sheathing must be maintained a distance not less than six inches from earth and at least two inches from concrete as in a stoop, landing or pato. If those distances can t be maintained, then the wood will have to be protected against decay. 26
The code contains specific requirements for the protection of fasteners and connectors whenever they come in contact with fire-retardant-treated wood, preservative-treated-wood, wood foundations, and wood in wet or damp locations. 27
The fasteners requirements have been expanded to include fasteners and connectors in contact with the preservative treated and fire retardant treated wood. 28
A definition and specific requirements for manufactured wood/ plastic composite materials are introduced into RCO. 29
Code sections specifically permit deck boards, risers, treads, handrail and guards. 30
Steel is now specifically listed as termite resistant and acceptable locations for use of preservative-treated-wood, physical barriers and naturally durable wood are indicated. 31
Building numbers or building identification must be approved and required to be plainly legible and visible from the street or fronting road. 32
Whenever there are four or more dwelling units or sleeping units in a single structure, the accessibility provisions of section 320 will apply. If nonrequired accessibility components are to be installed in exempt dwelling units, these components must still be installed to comply with ICC A117.1 standards. 33
Buildings that will be installed within flood hazard areas, are to be designed and constructed following ASCE 24 flood resistant design and construction. 34
ICC/NSSA STANDARD 500 Provides the requirements for the construction of storm shelters. While such shelters are not required by the code, if they are intended to be installed within a dwelling or as a separate accessory structure, they must comply with the provisions of this section. 35
This code section provides the requirements for accessory structures built as post frame buildings. The initial subsection outlines eight limitations on when such structures can be permitted ranging from no more than a single story to maximum post spacing of 8 feet. 36
A series of details are provided in the code including example drawings depicting various code provisions. Many come from the Post Frame Association s Handbook. Shown is an example of the several details in this code section. 37
