Texas Local Government Code - LOC GOV'T § 552.068. Exemptions; Personal Liability for Assessment

(a) All property, including church and school property, is subject to a tax or assessment authorized for local improvements under this subchapter. However, this subchapter does not authorize the municipality or its governing body to fix a lien against any interest in property that is exempt from the lien of a special assessment for local improvements under the constitution of this state at the time the lien takes effect. The owner of such a property is personally liable for any assessment made in connection with the improvement, and the municipality may refuse water or sewer service to the owner until the owner pays the municipality the assessment made against the property or an amount equal to the assessment made against private property of equal or comparable size. The fact that an ordered improvement is omitted as to property, an interest in which is exempt, does not invalidate the lien or liability of assessment made against any other property.

(b) The municipality may enforce a lien created against any property and the personal liability of the owner of the property by an action in a court having jurisdiction or by sale of the assessed property in the manner provided by law or charter in effect in that municipality for the sale of property for municipal property taxes.

(c) As an aid to enforcement of the liability imposed by the assessment, the municipality may refuse to connect or may disconnect water or sewer service to a parcel of benefitted property during the period in which there is a default in the payment of any amount assessed under this subchapter against the parcel or its owner.
