A daycare is the simpler start: most states ask only for a shop or trade registration, so the standard to build to is the Ministry of Women and Child Development's national creche guidelines, which set up to 30 children a unit, one adult for every 10 children under 3 and every 20 aged 3 to 6 plus a helper, 10 to 12 sq ft per child, a ground-floor space, and police verification of guards. The steadiest customers are employers: the 2017 Maternity Benefit amendment made a creche mandatory for any establishment with 50 or more employees, within 500 metres of the workplace, so a daycare near offices can sell seats to companies. A preschool adds teaching: base it on NCERT's National Curriculum Framework for the Foundational Stage (ages 3 to 8) and check your state's rules, since some states require preschools to register with the education department. One safety incident ends most, so hire, verify and train staff before you enrol a child.

A law firm's summary of why employers need creches: the 2017 amendment to the Maternity Benefit Act made a creche mandatory for any establishment employing 50 or more people, at or within 500 metres of the workplace, which is the demand a corporate daycare sells to.
