Engineering Development Process

Guidance Through the Development Process

All public improvements and infrastructure development or re-development within the City of McKinney requires a development permit prior to the start of any construction. 

To assist you through the development permitting and review process, we have created a guide PDF with valuable information to help you better understand our process. The "Civil Engineering Development Process and Requirements PDF" document outlines and defines the Civil Development process steps for all commercial development projects requiring public improvements including grading, paving and utilities. It also contains the contact information and links to the City of McKinney Design Manuals, Standards and General Notes.

To provide you with the best possible service, use the online Customer Self Service (CSS) portal to apply for your development permits and submit the required documentation for your development projects that require public improvements for grading, paving and utility work.

Please note that for all commercial development projects requiring public improvements and a development permit, commercial building permits may also be required. A separate tree permit application is also required prior to the initiation of construction.  

All applicable fees must be paid before a permit will be issued.
