Parking in Mozambique is generally unregulated and you’ll only find restrictions in the major cities like Maputo.
In the larger cities you are likely to come across car parking lots run by the owners of the land as well as the odd one or two parking garages. Near the central business districts, parking is restricted and monitored by the police.
There is little need for parking enforcement in Mozambique but the police do patrol the streets of the centre of the capital and other big cities looking for obstructions caused by cars being parked carelessly. If your car is one of them, expect it to be towed and to suffer a long period of frustration and cost before getting it returned.
There are many disabled Mozambicans thanks to the civil war of the latter parts of the 20th century but there are no concessions for parking for the disabled. Most people will be sympathetic and offer to help so you should find an attended parking lot and ask for help.
