Offices in residential areas

The government may tie up with Rajuk and DCC to enforce suitable residential environment for family life. It is not clear why regulatory monitoring is so lax, and deterrent punishment is virtually absent. Why no action is taken against the landlords? The licences of the NGOs and registered and unregistered private companies may be cancelled for violation of regulations, if warning and reminders are ignored.
Next to the residential building where I stay with my family (in a flat,) there is a big head-office of an industrial company, where factory goods are stored, and dozens of salesman crowd the premises all the time (the landlord-cum-owner lives on the top floor with his family). There is no signboard to indicate business activity!
