A system and method is disclosed for providing conditional access control using a parametric-based conditional access code. The parametric-based access code is generated by a access grantor, such as a homeowner, parent, employer, rental company, etc., from a set of parameter values associated with an access control device. Such parameters can include date and time, location, purchase amount, type of purchase, etc. Once a parametric-based access code is generated, it can be used by the grantee, i.e., the person seeking access, at the appropriate access control device. The access control device extracts the conditional parameter values and compares them to current parameter values of the access control device. Access is granted only when the conditional parameter values match the current parameter values.
