Planning Permission in Plymouth
Unitary Authority in South West · Last updated April 2026
Plymouth is a major city and naval port on the south Devon coast, with 15 conservation areas, one Article 4 direction, and 785 listed buildings. The city's planning context is shaped by its maritime heritage, post-war reconstruction, and the dramatic setting between Dartmoor and the sea.
The council processes around 700 applications annually with a 93.4% approval rate — one of the higher rates in the South West. Plymouth's diverse neighbourhoods range from the Georgian and Regency terraces of the Barbican and Stonehouse to the post-war city centre and suburban estates, each requiring different planning approaches.
Homeowners should check whether their property falls within any of Plymouth's local plan designations before starting work, particularly the conservation areas around the Barbican, Stonehouse, and Devonport.

Permitted development in Plymouth
Plymouth's 15 conservation areas and single Article 4 direction cover the most historically significant parts of the city, including the Barbican, Royal William Yard, Stonehouse, and parts of Devonport. Outside these areas, standard permitted development rights apply to the majority of Plymouth's residential properties. The absence of Green Belt and the relatively modest number of conservation areas compared to other authorities means that most homeowners have full PD rights for typical extensions and alterations.

Local Plan: Plymouth Plan 2014–2034
Plymouth City Council adopted its Plymouth Plan in April 2019. As the largest city in the south-west, Plymouth is a major growth location with policies for housing regeneration, the Ocean City economy and transport. The plan works alongside the South Hams and West Devon Joint Local Plan for the wider Plymouth sub-region.
Emerging / replacement plan
Plymouth is preparing a new Local Plan. A Regulation 18 consultation ran in 2022–2023, with a Regulation 19 Pre-Submission plan anticipated in 2025 and adoption targeted for 2026.
93.4% approval rate
Plymouth approves 93.4% of planning applications, above the national average of 86.9%. Well-designed residential applications in this area tend to have a good chance of success.
Conservation areas in Plymouth
15 designated conservation areas
Plymouth's 15 conservation areas protect the city's most important historic environments, from the medieval Barbican — one of the best-preserved harbour quarters in England — to the Georgian terraces of Stonehouse and the naval heritage of Devonport. Properties within these areas face restrictions on extensions, dormers, and external alterations. The council pays particular attention to maintaining the character of the waterfront areas and the distinctive Plymouth limestone and stucco building traditions.

Listed buildings in Plymouth
There are 785 listed buildings in Plymouth. If your property is listed, permitted development rights are significantly restricted.

Always check with Plymouth's conservation team before starting any work on a listed property.
Planning application statistics

Plymouth received 699 planning applications and decided 699 in the year ending September 2025. The approval rate of 93.4% is above the national average of 86.9%. Major applications are expected to be decided within 13 weeks, while householder and other non-major applications have an 8-week target. The “in time” figures include decisions made within agreed extensions of time.
Plymouth City Council handled 699 planning applications in the year ending September 2025, with a 93.4% approval rate across 699 decisions. The council processed 328 householder applications. The city's high approval rate reflects Plymouth's generally supportive approach to development within the framework of the Joint Local Plan. The council operates with a high delegation rate, with most decisions made by planning officers.
If your project complies with permitted development rules, you don't need to worry about approval rates — a Lawful Development Certificate is a factual assessment, not a judgment call.

Housing delivery in Plymouth
Housing Delivery Test 2023 measurement | Source: MHCLG
Plymouth delivered 3,917 homes against a requirement of 3,477 over the three-year measurement period, giving a Housing Delivery Test score of 113%. This is above the 95% threshold, which means there are no government-imposed consequences for housing under-delivery. Planning applications in Plymouth are assessed on their own merits under standard planning policies.
Lawful Development Certificates in Plymouth
A Lawful Development Certificate (LDC) is formal confirmation from Plymouth that your project is lawful under permitted development rules. It is not legally required before you build, but it is the only official document that proves your project did not need planning permission. Most solicitors will ask for one when you come to sell, remortgage, or insure your property.
Plymouth decided 328 householder applications in the year ending september 2025. Their 8-week performance of 96% is above the national average of 93%, which suggests LDC applications are likely to be processed on time. LDC applications follow the same 8-week statutory determination period as householder planning applications.
How to apply for an LDC in Plymouth
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Plymouth's website. You will need to submit:
- A completed application form (available on the Planning Portal)
- A site location plan at 1:1250 or 1:2500 scale
- Existing and proposed floor plans and elevations
- A written description of the proposed works and how they comply with the GPDO 2015
- The application fee of £258
Plymouth must issue a decision within 8 weeks. If the application is approved, the certificate is a permanent legal record that the development is lawful. If refused, you can appeal to the Planning Inspectorate or amend your project and reapply.
