PIKES PEAK REGIONAL BUILDING DEPARTMENTResidential Deck Plan CheckThe following items are required for all deck plan reviews; covered decks require additional information. Walk-through plancheck is limited to 15 minutes. If more time is required, the plans are checked in at the front counter for a 3-day review period.PLOT PLANDrawn to scale and includes:Complete street address.Legal description of property.Property lines and dimensions.Include side, front and rear yards.All site improvements, including existing and proposednew construction (deck, patio enclosure, garage, etc.)Show window well locations and clearances.Egress window well requires 24” clearance between top ofwindow well and bottom of deck framing. Egress windowwell opening through the deck must be protected with aguardrail or approved grate cover that requires 30 lbs orless to open. Non-egress window well must have an 18”clearance between top of window well and bottom of deckframing for light and ventilation.DECK STRUCTUAL FRAMING PLAN & OVERVIEW PLANDrawn to scale (1/4” preferred), fully dimensioned, includes:Framing material.Joists and beams must be Hem Fir #2 or better. Use treatedmaterial for joists less than 18” and beams 12” from ground.Joist sizes and spacing of all repetitive framing materials.Beam sizes. All beams must have full bearing. Engineeredbeam products for exterior use must be of wolmanizedmaterial or properly weather protected.No bolting through joists and beams without approvalstamp of a Colorado licensed design professional or RBDPlan Check approval.Beam splices must be directly over post; mid-spansplices are not allowed unless engineered.Ledger. Ledger boards must be weather protected by anapproved method; usually 2 - flashing or spacing. Ledgerscannot be attached to a cantilever, brick veneer or manufacturedhome without the approval stamp of state of Coloradolicensed design professional. Information must include:SizeConnection type:Size and quantity of lag bolts,Lag screws and/or nailsSupporting material:RimStudConcreteConcrete masonry unitSpecify hangers usedPosts. Information must include:Material Size HeightDECK MATERIALSpecify material and thickness of decking. Code allows anytype of wood that is “naturally resistent to decay.” Redwood iscommonly used. Composite materials must be ICC approved.Review the ICC Evaluation Reports - a link is available on ourweb site under Plan Check/Handouts & Drawings. Installationsof composite deck materials must comply with the ICC evaluationreports; reports must be on site at inspection.FOUNDATION PLANSoil bearing capacity stated as shown on the soilsreport. If unknown, 1,500 psf will be assumed.Location of piers shown.Diameter of piers specified.Footing detail provided, (see RBD handout).Hot tub location and dimensions indicated, if any.Detached decks less than 30” above grade may beplaced on piers with a 12” depth or other approved methodsuch as bearing directly on an existing concrete slab.STAIR SECTIONSStringers: Material, Size, and SpacingRise/Run dimensions: 8” maximum rise, 9” minimum run.GUARDRAIL & HANDRAIL SYSTEMSStairs with 4 or more risers require handrails installed between34 – 38” above landing and nosing of the stair treads.The grip of the handrail cannot be less than 1 ¼” or more than2” in diameter. The 2003 International Residential Code allowshandrails to be constructed of 2 x 3 or greater material (2 x 4,2 x 6, etc.) placed on end and provided with a graspable fingerrecess area on both sides of the handrail profile. For specificinformation, refer to R311.5.6.3 of the 2003 IRC.Decks more than 30” above grade require a minimum guardrailheight of 36” and maximum 4” spacing between balusters.Composite materials must be ICC approved. Please review theICC Evaluation Reports - a link is available on our web siteunder Plan Check/Handouts & Drawings. Installations of compositeguardrail and handrail systems must comply with theICC evaluation reports; reports must be on site at the time ofinspection. (Note: If the composite guardrail differs from theICC approved installation, stamped engineering drawings arerequired. Please call our office for detailed requirements.)NAIL/SCREW USAGEWood screws can be used on decking planks, but only nailsare acceptable for hangers. End nailing or toe nailing of joists isnot allowed; use full height hangers for all connections.Contact RBD regarding specific applications of screws/nails.2880 International Circle, Colorado Springs, Colorado 80910 Telephone 719-327-2880 Web site www.pprbd.org091306/011006
