"Annexation is the process of bringing property into the City limits. An ordinance, which must be approved by the City Council, is required to make an annexation effective." 

The State of Texas grants cities authority to annex territory in two different ways:

• Annexation can be requested by a property owner (voluntary exempted process); and
• the City can annex a property without the consent of the owner (non-voluntary process).

All annexations must be carried out according to State law and the City Code of Ordinances.  As a "home-rule" city of more than 50,000 people, Conroe has the authority to annex property contiguous with and within three and a half miles of its current city limits, following procedures consistent with Chapter 43 of the Texas Local Government Code.
