Tennesse Code Relevant law:
T. C. A. § 39-14-408: A person is guilty of vandalism if you cause property damage in any way without the effective consent of the property owner.
On the matter of restitution and punishment, subsection (c) of the same section prescribes that:
1) Restitution for Vandalism is to be determined as listed in T. C. A. § 39-11-106(a)(36), which basically (with exception) just says the value of the restitution you have to pay is approximated by the $$ needed to return the vandalized property to its pre-vandalism condition (see above graffiti example).
2) Punishment for Vandalism (and offense grading) will be based on the TN statute for Theft at T. C. A § 39-14-105.
Punishment and offense grading for vandalism (theft) is highly dependent on the value of the damage. Also, if you damaged property belonging to more than one person, a) you may be charged with one count of vandalism/theft for EVERY victim; and b) the grading of the offense in case of multiple victims is to be based on the aggregated value of damage.
So basically your possible punishment/criminal record will include:
Lowest: Damage/restitution Less than $500; Class A misdemeanor.Note: this is the ONLY class of the offense that is not a felony and even a Class A misdemeanor is very seriousAll charges resulting from MORE than $500 in damage can be charged as a felony.
As the value of the damage goes up, the degree of felony goes up.
Hopefully you didn't do more than $500 in damage, which if true, would limit your crime to a misdemeanor. It is so so important that you get an experienced criminal attorney in your area ASAP, the crime of vandalism in TN is actually relatively very serious (compared to other states such as PA).
Theoretically, for vandalism under $500 you could receive "not greater than eleven (11) months twenty-nine (29) days in jail or a fine not to exceed two thousand five hundred dollars ($2,500), or both, unless otherwise provided by statute."- As authorized under T. C. A. § 40-35-111(e)(1). Penalties grow much much more serious if crime is a felony because the value of damage is higher.
