1030.1 JURISDICTION, CODES AND EASEMENTS

A. Definitions:

1. Building Codes, in general, refer to sets of requirements governing the design, construction, alteration, maintenance and use of buildings. They specify the minimum requirements to adequately safeguard building occupants� health, safety, and welfare.

2. Model Building Codes refer to minimum design provisions and practices established by nationally recognized coordinating bodies made up of building professionals from all interested organizations. They are developed using consensus processes, they require the use of referenced national consensus standards and specifications, and they can be used as templates for AHJs to use when developing their local ordinances.

3. Authorities Having Jurisdiction (AHJ): AHJs adopt and enforce a comprehensive building code package by ordinance. They can adopt the model codes in their entirety or amend them as necessary depending on their laws and regulations.

4. Federal Basic Design and Construction Policies: Follow nationally recognized model building codes and other applicable nationally recognized codes that govern Federal construction to the maximum extent feasible and consider local building code requirements. (See 40 U.S.C. 3310 and 3312.)

a. 40 U.S. Code § 3312 - Compliance with nationally recognized codes

i. Application:

A) To any project for construction or alteration of a building for which amounts are first appropriated for a fiscal year beginning after September 30, 1989.

ii. Building Codes: Each building constructed or altered by the General Services

Administration or any other federal agency shall be constructed or altered, to the maximum extent feasible as determined by the Administrator or the head of the federal agency, in compliance with one of the nationally recognized model building codes and with other applicable nationally recognized codes, including electrical codes, fire and life safety codes, and plumbing codes, as the Administrator decides is appropriate. In carrying out this subsection, the Administrator or the head of the federal agency shall use the latest edition of the nationally recognized codes.

iii. Zoning Laws: Each building constructed or altered by the Administration, or any other federal agency shall be constructed or altered only after consideration of all requirements (except procedural requirements) of the following laws of a State or a political subdivision of a State, which would apply to the building if it were not a building constructed or altered by a federal agency:

Vale, Oregon

SECTION 1030

PROJECT CRITERIA PAGE 2

A) Zoning laws.

B) Laws relating to landscaping, open space, minimum distance of a building from the property line, maximum height of a building, historic preservation, esthetic qualities of a building, and other similar laws.

a) in preparing plans for the building, consult with appropriate officials of the State or political subdivision of a State, or both, in which the building will be located.

b) on request, submit the plans in a timely manner to the officials for review by the officials for a reasonable period of time not exceeding

30 days: and

c) permit inspection by the officials during construction or alteration of the building, in accordance with the customary schedule of inspections for construction or alteration of buildings in the locality, if the officials provide to the Administrator or the head of the federal agency:

a. a copy of the schedule before construction of the building is begun; and

b. reasonable notice of their intention to conduct any inspection before conducting the inspection.

d) State and Local Government Recommendations: Appropriate officials of a State or political subdivision of a State may make recommendations to the Administrator or the head of the federal agency authorized to construct or alter a building concerning measures necessary to meet the requirements of subsections (b) and (c). The officials also may make recommendations to the

Administrator or the head of the federal agency concerning measures which should be taken in the construction or alteration of the building to consider local conditions. The Administrator or the head of the agency shall give due consideration to the recommendations.

e) Effect of Noncompliance: An action may not be brought against the

Federal Government and a fine or penalty may not be imposed against the Government for failure to meet the requirements of

Vale, Oregon

SECTION 1030

PROJECT CRITERIA PAGE 3

subsection (b), (c), or (d) or for failure to carry out any recommendation under subsection (e).

f) Limitation on Liability: The Government and its contractors shall not be required to pay any amount for any action a State or a political subdivision of a State takes to carry out this section, including reviewing plans, carrying out on-site inspections, issuing building permits, and making recommendations.

B. Authority Having Jurisdiction:
