Abstract
We use Dirac matrix representations of the Clifford algebra to build fracton models on the lattice and their effective Chern-Simons-like theory. As an example we build lattice fractons in odd $D$ spatial dimensions and their $(D+1)$ effective theory. The model possesses an anti-symmetric $K$ matrix resembling that of hierarchical quantum Hall states. The gauge charges are conserved in sub-dimensional manifolds which ensures the fractonic behavior. The construction extends to any lattice fracton model built from commuting projectors and with tensor products of spin-$1/2$ degrees of freedom at the sites.

List of changes
*We have also included in the additional Appendix E the discussion of how theories with different K-matrices are equivalent,
*We have added to the manuscript equations (22) and (23) and a discussion about the compactification of the fields;
*We have included in the manuscript a discussion about the level quantization in Sec. IV A, and
also a new appendix (Appendix D) with further details of the calculation;
*In addition to the major changes required by the referee, we have also addressed all the listed
minor changes.
We thank the referee for the constructive and valuable criticism.
