      Optional Requirement

      This section of the approved document deals with the following optional requirement from Part M of Schedule 1 to the Building Regulations 2010. Requirement Optional requirement Part M access to and use of buildings Category 2 – accessible and adaptable dwellings M4(2) optional requirement (1) Reasonable provision must be made for people to— (a) gain access to; and (b) use, the dwelling and its (2) The provision made must be sufficient to— (a) meet the needs of occupants with differing needs, including some older or disabled people; and (b) to allow adaptation of the dwelling to meet the changing needs of occupants over time. Limits on application Optional requirement M4(2)— (a) may apply only in relation to a dwelling that is erected; (b) will apply in substitution for requirement M4(1); (c) does not apply where optional requirement M4(3) applies; (d) does not apply to any part of a building that is used solely to enable the building or any service or fitting in the building to be inspected, repaired or maintained. Performance In the Secretary of State’s view, optional requirement M4(2) will be met where a new dwelling makes reasonable provision for most people to access the dwelling and incorporates features that make it potentially suitable for a wide range of occupants, including older people, those with reduced mobility and some wheelchair users. Reasonable provision is made if the dwelling complies with all of the following. a. Within the curtilage of the dwelling, or of the building containing the dwelling, it is possible to approach and gain step-free access to the dwelling and to any associated parking space and communal facilities intended for the occupants to use. b. There is step-free access to the WC and other accommodation within the entrance storey, and to any associated private outdoor space directly connected to the entrance storey. c. A wide range of people, including older and disabled people and some wheelchair users, are able to use the accommodation and its sanitary facilities. d. Features are provided to enable common adaptations to be carried out in future to increase the accessibility and functionality of the dwelling. e.
