What is a domestic property and a residential property with regard to fire sprinkler regulations?

Domestic or Residential Property?

Domestic or Residential Property?

domestic property in BS 9251:2005 is defined as dwelling that has no more than one family unit. This could be a house, individual flats and maisonettes. BS 9251:2005 requires that a sprinkler system must be designed to ensure that two sprinkler heads can be fed by a water supply for at least 10 minutes. With the introduction of the BS9251:2014 all are regarded as residential properties and fire sprinkler systems are divided into categories 1, 2 and 3. Catagory 1 residential sprinklers are broadly equivalent to what previously domestic fire sprinklers or home fire sprinklers.

residential property in BS 9251:2005 is classed as a care home, nursing homes, blocks of flats, home of multiple occupancy (HMOs). BS 9251: 2005 requires that a sprinkler system must be designed to ensure that four  sprinkler heads can be fed by a water supply for at least 30 minutes.

A residential system is different from a commercial system. It is therefore important to specify the terminology clearly.
