Re: Minimum Plan Requirements
1. (2) Complete sets of legible building plans drawn to scale (1/4" or 1/8'=1'),showing conformance to the applicable local & state building codes. Lateral design details & connections must be incorporated into the plans or on a separate full size sheet attached to the plans with cross-references between plan location & details. For approved Master Plans, submit the stamped re-issue set with two additional sets of plans. Include 1 extra floor plan.
2. (2) Site/Plot plans drawn to scale (1" = 20') & the scale used noted on the plot plan. The plan must show: North arrow, lot & building setback dimensions; property corner elevations (if there is more than 1-ft. elevation differential, the site plan must show contour lines at 2-ft. intervals for a distance away from the building); location of easements & driveway, access restrictions, street names, footprint of structure (including decks), location of wells/septic systems, utility locations, any known fill sites or landslide hazard areas, direction indicator, lot area, impervious area, existing structures on site & surface drainage(see Engineering requirements). Please provide the percentage of the slope. Show location(s) and dimensions of driveway approaches and include wings (minimum cut width is 20',maximum is 33' - see back of this form for details).
3. Foundation plan & Cross Section. Show footing & foundation dimensions, size & dept of all enlarged footing s for point loads, anchor bolts, any hold-downs & reinforcing steel, connection details, foundation vent size & location.
4. (3) Floor plans. Show all dimensions, room identification, door & window sizes & locations, location of smoke detectors, water heater, HVAC equipment, ventilation fans, plumbing fixtures, balconies & decks 30 inches above grade, etc.
5. Cross sections(s) & details. Show all framing member sizes & spacing such as floor beams, headers, joists, sub-floor, wall construction, roof construction. More than one cross section may be required to clearly portray construction. Show details of all wall & roof sheathing, roofing, roof slope, ceiling height, siding material, footings and foundation, stairs, fireplace construction, thermal insulation, etc.
6. Elevation view. Provide elevations for new construction; minimum of two elevations for additions & remodels. Exterior elevations must reflect the actual grade. Full size sheet addendums showing foundation elevations with cross-references are acceptable.
7. Wall bracing (prescriptive path) and/or lateral analysis plans. Building plans must show construction details & locations of lateral brace panels; for non -prescriptive path analysis provide specifications & calculations to engineering standards.
8. Floor/roof framing plans are required for all floors/roof assemblies indicating member sizing, spacing & bearing locations, nailing & connection detail. Show location of attic ventilation. For engineered systems, provide manufacture engineer stamped floor/truss design details.
9. Beam calculations. Provide two sets of calculations using current code design values for all beams & multiple joists exceeding prescriptive code requirements, and/or any beam joist carrying a non-uniform load.
10. Compliance with Energy Table N1101(1) and Additional Measure from Table N1101.1(2). Additional Measure# _______. For Commercial please obtain the Building Code Compliance Forms located at
