Building Code Consultation

Code Books imagePre Design (establish parameters)

  • Determine Jurisdictions having Authority (zoning and or code(s))
  • Research and summarize zoning regulations
  • Research and summarize applicable code (building (existing), energy conservation, plumbing, accessibility, health, etc.)
  • Obtain survey or documentation of existing conditions (site and/or existing building)
  • Determine if zoning requires appeal or conditional use hearing
  • Establish building code project type (New construction, addition, change of occupancy, alteration level I, II or III)
  • Determine final/resulting occupancy type(s) (A1, A2, A3, A4, A5, B, E, F1, F2, H1, H2, H3, H4, H5, I1, I2, I3, I4, M, R1, R2, R3, R4, S1, S2, U)
  • Determine existing or desired building height (in feet from grade plane to mean roof and stories above grade plane) and area (bound by interior surface of exterior or ‘fire walls’ per story including projection of floor or roof above)

Preliminary analysis (using parameters established in Pre Design)

  • Determine if occupancy requires fire suppression throughout ‘building’ or ‘fire area’
  • Determine if allowable building area may be increased due to an perimeter open by >/= 20’ from building exterior walls to a property line, centerline of a right-of-way, imaginary property line (where more than single building on same lot) or unbuildable easement
  • Determine options for construction type based upon occupancy, building height, building area, if fire suppression present throughout ‘building’, and/or if occupancies are non-separated, separated by ‘fire barriers/horizontal assemblies’ or ‘fire walls’
  • Determine if building could be classified as an ‘unlimited area building’ if appropriate occupancy type, construction type, one or two stories, open perimeter of 60 feet (40 feet for up to 75% of perimeter if meet three conditions) on all sides of building and has zoned fire suppression throughout

Advise/select energy conservation code compliance path option

  • Determine if Residential (R-2, R-3 or R-4 occupancy not more than 3 stories above grade in height), Commercial (other than R-2, R-3 or R-4 occupancy or more than 3 stories above grade in height), or combination building project
  • If a Residential building project, determine which edition of model code (i.e. IECC) or State written code is applicable
  • If a Commercial building project, determine which edition of model code (i.e. IECC or ANSI/ASHRAE/IES Standard 90.1) or State written code is applicable
  • If adopted model code is applicable, select desired compliance path. Note that commercial buildings likely have the option of choosing one of 2 paths within the IECC or one of 3 paths within the ANSI/ASHRAE/IES Standard 90.1.

Outline analysis in .dwg file format (text and graphic file that may be incorporated into designerCode Summary image’s drawings)

  • Obtain copy of preliminary drawings from the designer (minimum of site plan, floor plans, exterior elevations)
  • Develop outline analysis of major aspects of building, accessibility and energy conservation codes that apply to building projects of all sizes/types
  • Note items on outline analysis that have options that must be determined/selected by the designer
  • Add or modify items in outline analysis based upon specific project conditions
  • Complete final version of outline based upon input/decisions made by the designer


Construction Document review (review progress and or final construction documents)

  • Obtain copies of progress and final construction documents from designers (including engineering consultants)
  • Review documents for more specific code related compliance details
  • Correspond with designer via written or graphic comment regarding specific requirements
  • Update outline analysis as more detailed document development requires
  • Authority Having Jurisdiction (AHJ) correspondence (written or verbal)
  • Respond to written or verbal document submission review comments by AHJ’s
  • Provide written, graphic or verbal support to designer during correspondence with AHJ’s

Construction phase

  • Respond to written or verbal questions from designer (re AHJ or contractor RFI’s)
  • Participate in or conduct on site inspections regarding code related issues
