Frequently Asked Questions
CTAC is aimed at anyone involved in a commercial project, including the owner, developer, engineer, architect or contractor. It is not intended to be a second opinion on a code interpretation already given by a plan reviewer or inspector. Questions can be answered before the permitting process begins. After you've entered into the preliminary code review or permit application process, the interpretations of your reviewer or inspector prevail.
For commercial code interpretation questions, visit or call CTAC at 704-432-4668.

Commercial Sub Permits (single trade permits)
Stand-alone permits may be issued for minor work on a case-by-case basis. Commercial Sub-permits are handled through the Commercial Technical Assistance Center (CTAC). Customers are required to come in person to our offices at 700 N Tryon Street, 1st Floor or submit an on-line application through the contractor's dashboard. The appropriate sub-permit application must be completed and signed and accompanied by a completed and signed address verification form. If the sub-permit is for work being performed on a project under construction, please bring a copy of the approved drawings in order to verify the work being permitted. If the work being requested on the sub-permit application requires drawings, the customer will be notified and the customer will need to submit drawings for review, either through OnSchedule Review or CTAC review.
Sub-permits can also be submitted through the TIP program. Mecklenburg County requires contractors to have a permit for certain projects and now it is an easy online process. The contractor Trades Internet Permits (TIP) online process allows you to enter details of the work being performed for projects that do not require a Building permit, pay the permit fee and print the permits.
From major conventions and international sporting events to community-based festivals, parades and athletic activities, the City of Charlotte and Mecklenburg County are proud to host nationally recognized events each year.
It is our goal to enhance the vitality, quality of life, and economic prosperity of Mecklenburg County along with the Towns of Cornelius, Davidson, Huntersville, Matthews, Mint Hill and Pineville.
Please visit the Special Events page for a full program description.

CTAC Electronic Plan Submittal
Beginning November 1, 2012 the complete CTAC process, permitting, plan submittal and plan review can be accomplished from your computer. Code Enforcement customers with an established Contractor account and properly licensed, can submit a permit application and attach the electronic plans in PDF format for projects fitting the CTAC plan submittal project types listed below and according to the Guidelines for Packaging Drawings for CTAC EPS. Click HERE for a brief description of the process. You may also view a FLOWCHART of the CTAC-EPS process. A step by step process may be viewed HERE. Electronic Plan Submittal requirements are as follows:
- Project types are limited to the Project Types listed below
- Project plans shall be compiled into one PDF file including an Appendix B and a table of contents.
- Drawings shall be orientated as Landscape & formatted to scale.
- Drawings shall be bookmarked by page.
- The gate keeper checklist and any other supporting documents shall be separate attachments.
- The electronic permit application must be complete and include all associated trade contractors.
- If the submittal is an RTAP, a copy of the approved project's plans must be included in the submittal as a separate file. RTAP projects that do not require a new permit must currently be submitted through the paper process.
Failure to comply with these requirements will result in cancellation of the project and permit application.
A Step-by-Step Process for Paper Submittal
(This process has changed since the implementation of the electronic process)
Customer must choose to either convert there paper plans into an electronic PDF Format or encounter additional fees for Code Enforcement to manage this process.
Time delays will be encountered during this process.
Submit project to the CTAC Coordinator. You will need to submit the following:
1 sets of drawings (minimum 18" X 24"), bound and stapled, with an Appendix B
1 completed Building Permit application(with contractor/sub-contractors/cost of construction).
1 Letter of Authorization from the General Contractor listed on the permit (when applicable).
1 Address Verification form
1 Plan Submittal for CTAC Plan Review form
1 completed Self-Gatekeeping Checklist
Once project is accepted, the CTAC Coordinator will contact a vendor to pick up the plans to convert them into an electronic PDF format. The vendo will send the electronic file to the CTAC Coordinator along with a bill for the conversion services. This process could add one or more days to the process.
Option: The customer may choose to perform this step themselves to avoid unnecessary time delays and pay for the plan conversion services. The customer may return to our facilities where Code Enforcement staff can assist them in submitting their project using our lobby computers (first time only).
The CTAC Coordinator sets up the project and starts the plan review process
CTAC review is typically a 5-day review process and approved projects will be issued permits at the time of approval, subject to permit application completion.
Disapproved projects will be returned with comments summarizing the defects.
Once the project is approved, additional administration fees of $31.60 per hour plus plan conversion fees from the vendor will be added to the permit/plan review fees for the project.
