Landlords in Northampton who want to covert houses into small HMOs will be required to obtain permission from the council to do so from November.
An Article 4 direction is already in place in some parts of the town, and the new direction will apply to the areas not already covered by this.
A consultation on the new direction ran last year, and the plans were approved last month. The new Article 4 direction will be introduced in Northampton on 13th November 2020.
Landlords are already required to apply for planning permission if they wish to convert a house to a larger HMO, for seven or more unrelated people.
