Can residence and commercial be in same building with c3 zoning?

Yes, in many jurisdictions, C3 zoning allows for a mix of residential and commercial uses within the same building. This typically includes ground-floor commercial spaces with residential units above. However, specific regulations and requirements can vary by locality, so it is essential to check the zoning regulations for the specific area in question. Always consult local zoning ordinances or a planning official for accurate guidance.
