What is a Development Agreement?

A Development Agreement sets out the terms between a property owner and a developer for transforming land or buildings. It covers essential details like construction timelines, planning permissions, and who handles specific responsibilities during the project.

These agreements play a vital role in English property law, especially for complex builds and regeneration schemes. They protect both parties by clearly defining payment structures, quality standards, and what happens if things go wrong. Local authorities often use them to ensure developers deliver community benefits like affordable housing or infrastructure improvements as part of major developments.

Sample clauses: standard wording in a UK development agreement

4. Satisfactory Planning Permission
4.1 The Developer shall at its own cost prepare and submit a detailed planning application for the Development to the Local Planning Authority within [20] Working Days of the date of this Agreement, and shall thereafter use all reasonable endeavours to obtain a Satisfactory Planning Permission.
4.2 A planning permission is a Satisfactory Planning Permission if it permits the Development and is not subject to any condition, or to any obligation under section 106 of the Town and Country Planning Act 1990, which would require the Developer to incur costs exceeding [£250,000] in aggregate or to provide more than [35]% of the residential units as affordable housing.
4.3 The Developer shall supply the Owner with a copy of each application, consultation response and decision notice within [5] Working Days of submission or receipt, and shall not withdraw any application or agree any planning obligation without the Owner's prior written consent, such consent not to be unreasonably withheld or delayed.
4.4 If a Satisfactory Planning Permission has not been granted by the Longstop Date, either party may terminate this Agreement by written notice given at any time before such permission is granted, and neither party shall have any claim against the other save in respect of any prior breach.

9. Practical Completion and Delay
9.1 The Developer shall carry out and complete the Works in a good and workmanlike manner, in accordance with the Approved Plans, the Building Regulations and all Requisite Consents, and shall procure that Practical Completion is achieved by the Target Completion Date.
9.2 Practical Completion occurs only when the Employer's Agent has issued a certificate of practical completion under the Building Contract and the Owner has received the Building Warranty, the collateral warranties listed in Schedule [3] and the health and safety file required by the Construction (Design and Management) Regulations 2015.
9.3 If Practical Completion is not achieved by the Target Completion Date, the Developer shall pay the Owner liquidated damages of [£2,500] per week (or pro rata for part of a week) up to an aggregate cap of [£150,000], which the parties agree is a genuine attempt to pre-estimate the Owner's loss.
9.4 The Target Completion Date shall be extended by such period as is fair and reasonable where delay is caused by an event of Force Majeure, by any act or omission of the Owner, or by a change in statutory requirements after the date of this Agreement.

Frequently Asked Questions

When should you use a Development Agreement?

A Development Agreement becomes essential when undertaking significant property projects, particularly those involving multiple phases or complex planning requirements. Property owners need one before allowing developers to start work on their land, especially for major residential developments, commercial builds, or mixed-use schemes.

It's particularly important when dealing with local authorities in England and Wales, who require formal agreements to secure planning obligations and community benefits. The agreement proves invaluable for managing risk in situations involving substantial investment, multiple stakeholders, or where the development timeline stretches over several years.

What are the different types of Development Agreement?

Site Development Agreement: For physical property and land development projects, covering construction phases, planning permissions, and infrastructure requirements
Software Development Outsourcing Agreement: Used when outsourcing software projects to external developers, with detailed IP rights and delivery milestones
App Development Contract: Specifically tailored for mobile application development, including app store requirements and user interface specifications
Web Developer Contract: Focused on website development projects, covering hosting, maintenance, and content management systems

Who should typically use a Development Agreement?

Property Owners/Landowners: Control the land or buildings being developed and set key requirements for the development
Property Developers: Take on the responsibility for executing the development project and meeting agreed specifications
Local Planning Authorities: Review, approve, and enforce planning conditions attached to Development Agreements
Solicitors: Draft and negotiate terms, ensuring compliance with planning law and protecting client interests
Financial Institutions: Provide funding and require Development Agreements as security for development finance
Architects/Surveyors: Contribute technical specifications and ensure compliance with design requirements

How do you write a Development Agreement?

Project Scope: Define exact development specifications, timelines, and phases of work
Planning Status: Gather all existing permissions, required applications, and local authority requirements
Party Details: Collect full legal names, registered addresses, and authority to sign for all involved parties
Financial Terms: Document payment structures, development costs, and funding arrangements
Site Information: Compile property title details, site surveys, and existing restrictions
Risk Assessment: Identify potential delays, construction risks, and mitigation strategies
Completion Criteria: Specify exact standards and conditions for practical completion

What should be included in a Development Agreement?

Parties and Properties: Full legal names, addresses, and detailed property descriptions with title numbers
Development Obligations: Specific works, standards, and timelines for completion
Planning Conditions: Required permissions, approvals, and compliance with local authority requirements
Financial Terms: Payment schedules, development costs, and funding arrangements
Warranties and Indemnities: Quality guarantees and risk allocation between parties

Dispute Resolution: Process for handling disagreements and applicable jurisdiction

What's the difference between a Development Agreement and a Community Development Agreement?

A Development Agreement differs significantly from a Asset Purchase Agreement in several key ways. While both deal with property transactions, they serve distinct purposes and operate differently under English law.

Timing and Process: Development Agreements focus on future improvements and construction, while Asset Purchase Agreements deal with immediate transfer of existing assets
Scope of Obligations: Development Agreements include ongoing commitments, construction specifications, and phased completion requirements; Asset Purchase Agreements typically involve one-time transfers with minimal ongoing obligations
Risk Distribution: Development Agreements spread construction and planning risks over time between parties; Asset Purchase Agreements usually transfer all risks to the buyer at completion
Planning Elements: Development Agreements often include detailed planning conditions and local authority requirements; Asset Purchase Agreements rarely address future development potential
