State of Nebraska Board of Engineers and Architects

Do I need an architect or professional engineer on my project?

Licensed architects and professional engineers are required to provide design and construction phase services for all projects regulated under the Nebraska Engineers and Architects Regulation Act.

These include:

  • Design services including the preparation of drawings, plans, specifications, and other documents that show the features and detail of the project to be constructed.

  • Preparation of plans required for the permitting process. These plans must include a seal, the design professional's signature, and date. Failure to obtain the proper seal with date and signature will delay your project.

  • Construction services including visits to the project site to determine that the project is being built as designed and that the processing of technical submissions required of the contractor is being completed.

The practice of architecture and engineering is defined in the E&A Regulation Act as well as requirements for organizational practice and coordinating professionals.

 

Please use our flowcharts for new construction and renovations and additions to help determine if you need a licensed professional on your next project. 


When the E&A Regulation Act is not followed:

  • Property owners and developers may be liable if a structure was in violation of the act when built.

  • Projects may encounter extensive delays and cost over-runs.

  • Architects and professional engineers risk disciplinary actions, including public reprimands, fines, and license suspension or revocation.

  • Property owners may be subject to fines and civil penalties authorized by state statute. In addition, expenses related to compliance enforcement may be levied.

  • Remediation costs may be substantial, including post-construction design review, documentation, and construction revisions.


Many small-scale, one-story building projects in Nebraska may be designed by persons who are not licensed as architects or professional engineers. The size limit on buildings that can be designed by non-licensed persons is based on three factors:

1) The size of the project in square feet.

2) The occupancy classification of the project as defined in the state building code.

3) The occupant load of the project as calculated in the state building code

Nebraska state law requires that any structure that will exceed the square footages defined in the E&A Regulation Act and Board Rules must be designed by an architect and/or professional engineer. What follows is a summary of the square footage definitions. Occupancy definitions and examples are taken from the State Building Code (The State Building Code references the International Building Code (IBC), International Residential Code (IRC), and International Existing Building Code, 2012 editions). Other local city and county requirements may also apply. There are numerous exceptions and additions not included in this summary. We encourage you to talk with an architect or professional engineer and consult with your local building officials and inspectors to make sure your project meets all state and local requirements.
