This summer, we built a new house with one of the Vlymhust manufacturers where we opted for a finished upper floor.
In one of the upstairs bedrooms, the ceiling is made of wood fiber boards, and the last row (about 50 cm wide) slopes down towards the exterior wall by about 1 cm. It is very noticeable and was reported.
According to the inspector, you must accept a slope according to the AMA table 27.E/35 of ceiling L/300 with a minimum of +/- 12 mm and a maximum of +/- 20 mm.
I can't find these tolerances anywhere when I search. When the house manufacturer's technicians checked it the other day, they said "it looks terrible and must be fixed" and were about to tear down the ceiling but were stopped by the manager at the house manufacturer, who referred to it being within tolerance.
The entire ceiling is straight, but the last half meter slopes so it's very noticeable. If the slope were across the entire ceiling, it wouldn't be so obvious.
Does anyone know what applies in this case?
It should be noted that it is a wooden house, prefab ground floor but finished upper floor on site.
