Drawing Plan Components

An index of drawings located on the first sheet which must include all occupancy classifications, types of construction, the area in gross square feet for each level, the maximum occupant load and the structural design loads.

Site Plan
A site plan showing to scale the size and location of new construction and all existing structures on the site, including:
  • Setback and side yard dimensions
  • All property and interior lot lines
  • Distances from lot lines and other buildings on the same lot
  • Street names and locations
  • Established street grades
  • Types and sizes of all utility lines
  • Elevations of all proposed finished grades
The site plan must be drawn in accordance with an accurate boundary line survey. In the case of demolitions, the site plan must show construction to be demolished and the location and size of existing structures and construction that are to remain on the site or plot. The building official is authorized to waive or modify requirements for a site plan when the application for approval is for alteration or repair or when otherwise warranted.

Utility Information
The following utility information shall be supplied on the site plan in order to process through the Utility Departments:
  • Electric service, location, voltage, wire and conduit size
  • Total electric loads in KW
  • Total gas loads in BTU
  • Size and location of gas and water service lines and meters
  • Size and location of storm and sanitary lines
Floor Plans
Complete floor plans, including plans of full or partial basements and full or partial attics and penthouses. Floor plans must show all relevant information such as door swings, stairs and ramps, windows, shafts, all portions of the means of egress, etc. and shall be sufficiently dimensioned to describe all relevant space sizes. Wall materials must be described by cross-hatching with explanatory key, by notation or by other clearly understandable method. Spaces must be identified by code appellation. The construction documents must designate the number of occupants to be accommodated on every floor, and in all rooms and spaces.

Cross sections, wall sections, details including typical connections as required to fully describe the building construction showing wall, ceiling, floor and roof materials. Construction documents must describe the exterior wall envelope in sufficient detail to determine compliance with the code. An energy-efficiency analysis of the total building envelope may also be required.

General Building Code Information
The fire resistance ratings of all structural elements as required by the code, data substantiating all required fire resistance ratings including details showing how penetrations will be made for electrical, mechanical, plumbing and communication conduits, pipes and systems and the materials and methods for maintaining the required structural integrity, fire resistance rating and fire stopping.

System Plans & Descriptions
Complete description of the plumbing, HVAC, gas and electrical systems. This includes the location, materials and sizes of all:
  • Piping
  • Fixtures
  • Equipment
  • Schematics
  • Duct work
  • Lighting and power
Fire Alarm & Sprinkler Systems
These drawings are required to be prepared by individuals certified in the state of Ohio to design these systems. The drawings for these will need to be submitted under separate permits.

Statement of Special Inspections
Where structural tests and special inspections are required by the Ohio Building Code, the applicant must submit a statement of special inspections prepared by the registered design professional as a condition for the issuance of the plan approval. This statement will include a complete list of materials and work requiring special inspections; the inspections to be performed; and a list of individuals, approved agencies, or firms intended to be retained for conducting such inspections. Additional drawings or information may be required in order to determine compliance with the applicable state codes.
