41 CFR 302-6.1: -6.1 Temporary quarters and temporary quarters subsistence expenses (TQSE) allowance.

The term temporary quarters refers to lodging obtained for the purpose of temporary occupancy from a private or commercial source incident to an official relocation or temporary change of station. TQSE is a discretionary allowance that an agency may use to reimburse an employee reasonably and equitably for subsistence expenses incurred when it is necessary to occupy temporary quarters. Transportation expenses incurred in the vicinity of the temporary quarters are not TQSE expenses; there is no authority to pay such expenses under TQSE.
