The council has adopted a number of Supplementary Planning Documents (SPDs), including the Design of Residential Extensions, the Urban Design Guide, the Sutton Garden Suburb Conservation Area Management Plan and on Planning Obligations.

The council has also produced non-adopted guidance notes, including the Interim Guidance Note on Biodiversity Net Gain (BNG) published in April 2025. This sets out the London Borough of Sutton's approach to applying the national mandate for BNG introduced by the Government in February 2024 and will apply until such time as Sutton's new Local Plan is adopted in around late 2026.
