Road adoption on new housing developments

When new housing developments are built, road adoptions can take many years before the local authority takes responsibility. The process for this is explained below:

What is road adoption?
Road adoption is the legal process through which a road becomes a publicly maintained highway. Once adopted, the local highway authority becomes responsible for maintaining the road at public expense.

Before adoption takes place, the roads usually remain the responsibility of the developer.

Why are roads not adopted immediately?
Roads on new developments must first be built to the standards required by the highway authority. This includes:
• Road construction
• Drainage systems
• Street lighting
• Footways and kerbs
• Traffic signs and markings
• Utility coordination
The developer must complete the works and demonstrate that the roads meet the required standards before adoption can happen.

What is a Section 38 Agreement?
Most new estate roads are adopted through a legal agreement known as a Section 38 Agreement under the Highways Act 1980.

This agreement is made between:

• The developer
• The local highway authority

The agreement sets out:
• The roads to be adopted
• Construction standards
• Inspection requirements
• Financial guarantees (bond/security)

Typical stages of the adoption process

1. Planning approval

The development receives planning permission, and road layouts are approved.

2. Section 38 Agreement signed

The developer enters into a legal agreement with the highway authority.

3. Roads constructed

Roads are built in phases as the development progresses.

4. Initial inspection

The highway authority inspects the roads to ensure they meet standards.

5. Provisional adoption

Once substantially complete, roads may enter a maintenance period.

6. Maintenance period

The developer remains responsible for repairs and defects, usually for 12 months.

7. Final adoption

After all outstanding issues are resolved, the roads are formally adopted by the council.

Final adoption
After all outstanding issues are resolved, the roads are formally adopted by the council.

Who maintains the roads before adoption?
Until adoption is completed:
• The developer is usually responsible for maintenance
• Residents may experience temporary road surfaces or unfinished landscaping
• Some street lighting or parking controls may not yet be fully operational

What should residents expect?
During the development phase, residents may notice:
• Ongoing construction traffic
• Temporary road surfaces
• Delays in final surfacing
• Incomplete footpaths or landscaping
• Utility works
These are common during phased developments and do not necessarily mean adoption will not take place.
How can residents check if a road is adopted?
Residents can:
• Contact the local highway authority
• Request a highways search
• Check council online highway records where available

Frequently Asked Questions

Will council tax pay for maintenance before adoption?
No. Before adoption, maintenance is generally funded by the developer.
Can residents force adoption?
Residents cannot usually force immediate adoption, but concerns can be raised with the developer and highway authority.
Why does adoption take so long?
The process can take several years because roads must be fully completed, inspected, and maintained defect-free before final adoption.
