Tamil Nadu Housing Board (TNHB) allots plots, flats, and houses through two structured digital systems:

1. Online Lottery System -Units are allotted through a computerized random draw among eligible applicants after the application period closes.
2. Online First Come First Serve (FCFS) System – Units are allotted instantly to the applicant who books and pays the initial amount first, subject to eligibility verification.

Both systems are governed by reservation norms, income classifications, and defined time schedules.
