Study Notes
Building Codes and Standards
- Emergency Escape and Rescue Openings: Maximum sill height is 44 inches.
- Ice Barriers: Regions prone to ice formation require two layers of underlayment.
- Window Wells: Minimum horizontal area is 9 square feet, and width is 36 inches.
- Ground Slopes: Ground surface around a building's perimeter (first 10 feet) should slope 6 inches.
- Exterior Caulking: Silicone rubber and urethane caulks generally provide the best performance.
- Basement Finishes: Avoid low permeability vapor retarders (like polyethylene, vinyl) on the interior of basement finishes in some climates due to moisture trapping.
- Floor Finishes on Slabs-on-Grade: Carpet and wood-based finishes can be applied directly to slabs-on-grade if the slab or finish surface temperature is near room temperature.
- Composition Shingle Roofs: Minimum roof slope is 2:12.
- Deck Loads: Decks distribute load through posts and deck-to-house connections, not just posts alone.
- Deck Posts: Minimum post dimensions are 6 inches by 6 inches, with cross-bracing; higher posts are allowed with additional support.
- Air Conditioner Temperature Drop: The air temperature drop across the evaporator coil should be 20 degrees when running.
- Gas Piping: Black iron is a common gas pipe material.
- Dew Point: The dew point is the temperature at which air must be cooled to reach saturation; below the dew point, moisture condensation occurs.
- Intermediate Rails/Balusters: Must withstand 50 pounds distributed over 1 square foot of area.
- Residential Frame Construction: Platform framing is the common residential method.
- Roof Types: A roof without a gable is called a hip roof
- NACHI Member Restrictions: InterNACHI members cannot perform repairs on structures they've inspected within 12 months.
- Chimney Storm Collars: Storm collars divert rainwater away from the chimney flue.
- Chimney Height (3-2-10 Rule): Masonry chimneys must extend 3 feet above the roof and 2 feet above any nearby.
- Chimney Flue Size: Determined by the area of the fireplace opening, not the chimney height or material.
- Air Conditioning System Operation: Do not operate air conditioners below 60°F.
- Dishwasher/Sink/Grinder: Dishwasher, food grinder, and kitchen sink can use a 1.5-inch waste drain, but must use separate pipes if exceeding that size.
- Flat Roof Venting: Flat roofs use passive venting systems, which can be prone to ponding.
- Sloped Roof Venting: Combination of soffit and ridge vents is best for asphalt shingles.
- Furnace Efficiency: Mid-efficiency furnaces typically have an AFUE rating of 78-82% and use intermittent-pilot ignition.
- Plumb Bob: Used to create a vertical reference line.
- Egress Door Minimums: Minimum egress door size is 2 feet wide by 6 feet tall.
