All rights or remedies are expressly saved as to any and all violations of any previous zoning ordinance or amendments thereto that have accrued at the time of the effective date of this Chapter; and as to such accrued violations the court shall have all the powers that existed prior to the effective date of this Chapter; and that all existing violations of previous zoning ordinances, which would otherwise become non-conforming uses under this Chapter, shall not become legal non-conforming uses under this Chapter, but shall be considered as violations of this Chapter in the same manner that they were violations of prior Zoning Ordinances of the City.
