City of London Regulation required every man to keep clean the front of his own tenement. Regulations for carrying out this edict were made in the reign of Edward I., and in year 1297 with regard to cleaning the streets. It was enacted that everyone should keep clean the front of his own tenement, that so the streets should be delivered from all encumbrances. A week’s grace only was given before the regulation came into force, and after this interval the owner of any house was liable to be fined half a mark. At the same time it was ordered that any swine found in the streets should be forfeited.
In 1309 City of London Regulation prohibited the casting of filth from houses into the streets and lanes of the City. People “ought to have it carried to the Thames or elsewhere out of town”.
