About section 106 agreements and unilateral undertakings
Section 106 Agreements (S106) and unilateral undertakings (UU) are types of planning obligation under Section 106 of the Town and Country Planning Act 1990.
They are legal agreements between the local authority and the developer. The agreements aim to balance the extra pressure a new develoment creates with improvements to the surrounding area. The improvements ensure the new development makes a positive contribution to the local area and community.
A planning obligation can:
- restrict the development or use of land
- mean you must carry out specific operations or activities on the land
- mean you can only use land in a certain way
- require the payment of financial contributions
Types of obligation commonly include provision of:
- affordable housing
- open spaces and recreational facilities including enhancement and maintenance
- play equipment
- art provision
- travel plans
