So a handrail is not necessarily required (DIN and so)?
Then you can also change a handrail (from one side to the other) :cool:
Inside single-family homes, I think no.
For example, the building code NRW, which already mentioned
§ 34 Building Code NRW 2018 – Stairs
(1) Every floor not at ground level and the usable attic space of a building must be accessible via at least one staircase (necessary staircase). Instead of necessary staircases, ramps with a gentle slope are permitted.
(2) Retractable stairs and escalators are not permitted as necessary staircases. In buildings of building classes 1 and 2, retractable stairs and ladders are permitted as access to an attic space without a habitation room.
(3) Necessary staircases must be continuous to all connected floors. They must be directly connected to the stairs to the attic. This does not apply to stairs
[*]1.
in buildings of building classes 1 to 3 and
[*]2.
according to § 35 paragraph 1 sentence 3 number 2.
(4) The load-bearing parts of necessary staircases must
[*]1.
in buildings of building class 5 be fire-resistant and made of non-combustible materials,
[*]2.
in buildings of building class 4 made of non-combustible materials, and
[*]3.
in buildings of building class 3 made of non-combustible materials or fire-resistant
be. Load-bearing parts of exterior stairs according to § 35 paragraph 1 sentence 3 number 3 for buildings of building classes 3 to 5 must consist of non-combustible materials.
(5) The usable width of stair flights and landings of necessary staircases must be sufficient for the greatest expected traffic. Deviating from sentence 1, a retrofitting of stair lifts can be permitted if
the guiding structure of the stair lift is at most 0.20 m wide and 0.50 m high, measured from the lower boundary of the stair's clearance profile,
a continuous remaining walking width of the stair of at least 0.60 m remains during an empty run of the lift, and
the unused lift is in a parking position that restricts the stair run no more than permitted by number 1.
(6) Stairs must have a fixed and grip-safe handrail. For stairs, handrails on both sides and intermediate handrails must be provided as far as traffic safety requires.
(7) A staircase must not begin immediately behind a door that opens in the direction of the staircase. A sufficient stair landing must be arranged between the staircase and the door, which should be at least as deep as the door is wide.
(8) Paragraphs 3 to 6 do not apply to stairs inside apartments.
