T.C.A. §§ 6-1-101 et seq.
There are no clear-cut purchasing requirements in the mayor-aldermanic (general law) charter. Since there are no provisions in the charter regulating competitive bidding and public advertisement, the 1983 Municipal Purchasing Law applies. However, the governing body of the municipality is authorized to increase or decrease the amount specified in the law concerning public advertising and competitive bidding.
All acquisitions made under this law must be purchased within the limits of the approved budget and appropriations for the department, office or agency for which the purchase is made.
