Manufactured homes are typically purchased from a retail sales Sentry Box company, initially assembled by a local contracting company, and follow-up repairs performed by the manufactured home company under warranty.

A manufactured home, once assembled, goes through a ‘settling-in’ period, where the home will settle into its location. During this period, some drywall cracking may appear, and any incorrectly installed appliances, wiring or plumbing should be repaired, hopefully under warranty. If not covered under warranty, the costs will be borne by the consumer. For this reason, it is important that the consumer ensure that a reputable and honest contractor is used for the initial set-up. If any repairs are not completed by the initial set-up crew, the manufacturer will send repair crews to repair anything covered by the warranty. The secondary repair team must be scheduled, and may not be available immediately for most repairs. Just because a manufactured home has been assembled does not mean it is immediately habitable; appropriate ventilation, heating, plumbing, and electrical systems must be installed by a set-up crew, otherwise, the buyer must wait for the manufacturer repair team or do it themselves.

Prefabricated home and movable structure: The first prefabricated homes and movable structures were invented in 16th century in India by Akbar. These structures were reported by Arif Qandahari in 1579.[1] It can be proved that the first mention of a prefabricated building was in 1160 to 1170 by Wace* as confirmed by Monsieur Pierre Bouet an historian who published the book "Hastings" (publisher Tallandier, 2014). He spoke of a castle transported in 'kit' form in an article in the French magazine Historia's special May/June 2015 edition featuring the Vikings (the Normans, who invaded England in 1066, descended from Vikings). Monsieur Bouet says that in Wace's epic poem, Roman de Rou, verses 6,516–6,526, it says as follows: They took out of the ship beams of wood and dragged them to the ground. Then the Count (Earl) who brought them, (the beams) already pierced and planed, carved and trimmed, the pegs (raw-plugs/dowels) already trimmed and transported in barrels, erected a castle, had a moat dug around it and thus had constructed a big fortress during the night. (*see Wikipea Wace 'Roman de Rou')

There is no pan-EU housing standard for this kind of home construction, as regulation has historically been at the national government level. There are however many EU directives that do apply to housing construction and design, but these directives do not directly affect the inter-EU modular home sector due to inter-EU free trade considerations. However, each modular home is legally expected or obliged to be integrated into the local building regulations once the final construction is finished.

There are a small number of prefab home builders in Australia. In the overall housing sector, Mobile Toilet housing construction is very small as the overall rate of housing construction has been very low due to slow population growth.
