Permitted Development Rights Explained
Permitted development is a national planning permission subject to detailed limitations, conditions and local restrictions.
The essential position
Permitted development rights are a national planning permission granted by the GPDO for defined classes of development. They are not a relaxation of all planning control: the proposal must satisfy every limitation and condition, and the right can be restricted by property type, planning history, Article 4 or designated land.
Key points
- Rights generally apply to houses, not flats or maisonettes.
- Previous additions and the original house baseline are critical.
- Article 4 Directions and planning conditions can remove rights.
- An LDC provides formal confirmation where lawfulness matters.
1. How the rights work
Schedule 2 of the General Permitted Development Order contains classes for house extensions, roof work, porches, outbuildings and other development. Each class has exclusions, numerical limits and conditions.
A proposal is either within the legal right or it is not. Planning officers do not balance benefits against a small breach.
- Identify the correct class.
- Check definitions as well as diagrams.
- Test the complete development, not selected dimensions.
2. Properties and locations with restrictions
Flats and maisonettes do not have the normal Part 1 householder rights. Houses created through certain change-of-use permitted development classes can also be excluded.
Conservation areas, National Parks, the Broads, National Landscapes and World Heritage Sites have additional restrictions. Listed buildings require separate consent for works affecting special interest.
- Confirm the property is a dwellinghouse for the class.
- Check Article 2(3) land.
- Review Article 4 Directions and old conditions.
3. Cumulative development and the original house
Many limits refer to the original dwellinghouse. Earlier extensions, dormers and outbuildings can reduce remaining allowances even if they were built decades ago.
Land ownership does not always equal the planning curtilage. Unusual plots, converted buildings and subdivided gardens need careful analysis.
- Research old maps and approvals.
- Measure previous additions.
- Define the curtilage before calculating coverage.
4. Evidence and Lawful Development Certificates
A homeowner can proceed without an LDC where the development is unquestionably permitted, but a certificate creates a formal record and requires the council to assess the legal tests before construction.
The application should include exact drawings, calculations and planning-history evidence. It does not replace Building Regulations or private consents.
- Apply before work for proposed development.
- Build exactly to certified drawings.
- Keep the certificate for conveyancing.
Questions homeowners commonly ask
Are permitted development rights automatic?
They are granted nationally, but only where the property and proposal satisfy every limitation and condition and no local restriction removes the right.
Do flats have permitted development rights for extensions?
The normal Part 1 householder rights apply to dwellinghouses, not flats or maisonettes.
Can a planning condition remove permitted development rights?
Yes. Conditions on an original or later permission can remove specified rights.
Is prior approval the same as permitted development?
Prior approval is a procedural requirement attached to certain permitted development rights. The development must still comply with the underlying class.
