It is the responsibility of the applicant to ensure all information is complete, accurate and up to date  \nIntroduction  \nThis guide is for informational purposes only. It is the responsibility of the  \nApplicant/Designer to review the building code and ensure all information is complete, accurate, and up to date.  \nImportant Notes  \nThe design and construction of a deck and/or Porch must comply with the Municipality of Port Hope’s Zoning By-Law as well as the Ontario Building Code (OBC) .  \nSpecial consideration must be taken if a deck is to support a hot tub or similar structures due to increased load.  \nDefinitions  \nDeck: A raised platform that is attached to a dwelling. A deck will generally require a Building Permit and will require protective guards if the walking surface is greater than 24”(610mm) above finished grade.  \nPorch: A covered structure (enclosed or unenclosed_ that usually forms part of the entrance of a dwelling. Any Porch requires a Building Permit and will require protective guards if the walking surface is greater than 24”(610mm) above finished grade.  \nPatio: A platform at grade level that is usually constructed of concrete or stone. A Patio generally does not require a Building Permit unless it interferes with an existing structure.  \nJoist: Dimensional lumber places perpendicular to beam that frames the floor system  \nBeam: Laminated dimensional lumber that supports the joists  \nBuilding Permit Checklist  \n☐Complete Application for a Permit to Construct or Demolish ☐Complete Schedule 1: Designer Information (or Commitment to Review)☐Confirm with Planning proposed location meets setback requirements  \nSite Survey showing: (Refer to Figure 9 on page 9)  \n☐Location of deck in relation to the house ☐Dimensions of proposed deck ☐Distance to property line(s)  \n☐Other buildings i.e. detached garage, shed and/or septic  \nPlans & Section Drawings showing: (Refer to Figures 10 & 11 on page 10)☐Footing & Foundation construction  \n☐Location, depth, size and spacing of piers ☐Framing material size, span, locations, and spacing ☐Height from finished grade  \n☐Method of attachment to dwelling  \n☐Details of guards, stairs, and handrails (if applicable)  \nFigure 1-Deck Detail  \nPiers  \nPiers shall not be less than 10” in diameter. Under most circumstances it may be preferable to expand the lower portion of a smaller pier to achieve the required bearing area rather than use a larger pier. (Refer to Figure 2)  \nFigure 2-Footing Options  \nSize  \nRefer to the table on the next page for minimum footing sizes. The values in Table 1 are based on a soil bearing capacity of 10.9 psi (75 kPa) . NOTE: Minimum required bearing area must be double where the soil bearing capacity is affected by a high-water table.  \nConcrete [OBC [9.3.1.6](9.3.1.6)]  \nPiers shall consist of poured concrete with a minimum compressive strength of 5 MPa (2200psi) after 28 days  \nHeight [OBC [9.15.2.3](9.15.2.3).(3)]  \nPiers shall not extend more than 3 times their width/diameter above grade  \nDepth [OBC [9.12.2.2](9.12.2.2)]  \nWhere a deck or porch is attached to a dwelling or required a guard, the minimum footing depth shall be 48”(1 . 2m) . Frost protection for footings is not required if the deck meets all the following conditions:  \na) The deck is less than 24”(600 mm) in height,  \nb) Is not attached to any structure,  \nc) Is not supporting a roof (which includes a pergola/trellis), and  \nd) The area of the deck is not more than 592 ft2 (55m2)  \n\n| MINIMUM REQUIRED FOOTING AREA (ft2) |  |  |  |  |  |  |  |  |\n| --- | --- | --- | --- | --- | --- | --- | --- | --- |\n|  |  | SUPPORTED JOIST LENGTH* (ft) |  |  |  |  |  |  |\n|  |  | 4’-0” | 5’-0” | 6’-0” | 7’-0” | 8’-0” | 9’-0” | 10’-0” |\n| BEAM LENGTH (ft) | 4’-0” | 8” x 8”\u003Cbr>(10” dia.) | 9” x 9”\u003Cbr>(10” dia.) | 10” x 10”\u003Cbr>(12” dia","cbCaiiSF4v2bvSmZ","https://ap.wps.com/l/cbCaiiSF4v2bvSmZ","pdf",1102067,11,"English","# Introduction\n## Important Notes\n## Definitions\n## Building Permit Checklist\n## Piers\n## Size","[{\"question\":\"What are the key requirements for deck or porch piers and footings?\",\"answer\":\"Piers must be at least 10 inches in diameter and typically use poured concrete with a minimum compressive strength of 5 MPa after 28 days.
