In depth

The full picture.

01

Firm registration

Engineering firms must register with the state engineering board in each state where engineering services are provided. Registration requires: ownership compliance, designated responsible engineer, firm name compliance, sometimes financial bonds or insurance.

02

Ownership requirements

Most states require majority (51%+) ownership by licensed Professional Engineers (PEs). Some states require 100% PE ownership. A few states allow flexible ownership with designated PE on staff.

03

Disciplines covered

Civil, mechanical, electrical, structural, chemical, environmental, manufacturing, software (some states), agricultural, mining, petroleum, nuclear, others. Each discipline has its own state board oversight.

04

Entity structure

PLLC or Professional Corporation typically required. Standard LLC and standard corporation often not permitted for engineering practice.

05

Designated responsible engineer

Each firm typically designates a PE who supervises professional work. This PE signs and seals drawings, calculations, and specifications.

06

NCEES coordination

National Council of Examiners for Engineering and Surveying (NCEES) facilitates multi-state individual PE licensure through reciprocity ("Comity"). NCEES Record simplifies applications.

07

Multi-state firm operations

Firm registration separately in each state. Individual PEs must hold license in each state where they perform engineering. Comity simplifies but does not eliminate state-by-state requirements.

08

PE seal requirements

All engineering work product (drawings, calculations, specifications) must be signed and sealed by a licensed PE. Unsealed work is not legally permissible for many uses.

09

Continuing requirements

Annual firm renewal; individual PE renewal with continuing education (PDH/CEU requirements); periodic board audits; specific discipline updates.
