Town and Country Planning Approval in Trinidad & Tobago: A Homeowner's Guide

What planning permission is

Planning permission is the government's approval to develop a particular piece of land in a particular way. In Trinidad & Tobago it is governed by the Town and Country Planning Act and granted through the Town and Country Planning Division (TCPD) on behalf of the Minister responsible for planning.

Its purpose is to check that what you propose fits the land-use policy and development standards for that location — the use, the density, the setbacks from boundaries and roads, access, drainage and so on. It is not a check of how the building is constructed; that comes later, at the building permit stage.

When you need it

The Act requires permission for development, which it defines broadly: carrying out building, engineering, mining or other operations on land, making a material change in the use of buildings or land, or subdividing land.

In practice, that includes:

• Building a new house or any other new building
• Structural additions and extensions
• Alterations or renovations that change a building's external appearance, size or use
• Changing the use of a building or land — for example, from residential to commercial
• Dividing a parcel of land into lots

The Act lists some things that are not development — for example, works that affect only the interior of a building or do not materially affect its external appearance, and using land around a house for purposes incidental to living in it. Whether a specific piece of work falls inside or outside the definition can depend on the details, so check before assuming an exemption applies.

DevelopTT: applying online

DevelopTT (opens in a new tab) is the government's online portal for development permitting. Launched in 2020, it replaced the paper-based system for planning permission, building permits and completion certificates. It is run through the Ministry of Planning, Economic Affairs and Development.

According to the Ministry, DevelopTT lets several agencies process an application at the same time and lets applicants track the status of their application online. As of September 2026 the Ministry reports that Regional Corporations, WASA and the Drainage Division use the platform, and that DevelopTT's services are available online at no cost to the public.

Outline application or full planning permission?

There are two kinds of application for planning permission:

An outline application is useful when you want to know whether a proposal is likely to be acceptable before spending money on detailed design — for example, before buying land or committing to a particular use.

What an application typically includes

DevelopTT publishes a document checklist for each type of application. At a high level:

For an outline application

• Deed or Certificate of Title
• Survey plan or cadastral sheet
• Location sketch
• A description of the proposal
• A conceptual plan — optional for simple developments, required for complex ones

For planning permission for a building

• Site plan
• Floor plans
• Elevations, showing ground level, all faces, colours and materials, and heights
• A section showing floor and roof heights
• Roof plan or roof details
• Topographical information — for hillside development and steeply sloping sites
• Deed

The checklist asks for a lot of detail on the site plan, including boundaries and dimensions, setbacks, adjoining roads, driveways and parking, drainage, water supply and sewage disposal, and the location of any septic tank. It also notes that a Certificate of Comfort is not accepted in place of a deed or certificate of title, that all pages of the deed must be submitted, and that survey plans must be signed by a licensed land surveyor.

Missing or incomplete documents can lead to your application being queried and delayed. Always work from the current checklist on DevelopTT — our guide to the drawings needed to build a house explains what each drawing is for.

How other agencies become involved

Planning decisions take account of input from other government bodies. Which ones are involved depends on the project and the site. DevelopTT lists agencies that may issue approvals or give advice, including:

• Municipal Corporations — building permits and completion certificates
• Drainage Division — drainage design, flood-prone areas and river setbacks
• Highways Division — road access and road setbacks
• County Medical Officers of Health — public health approval
• Fire Services — fire approvals and inspections, where required
• Environmental Management Authority — Certificates of Environmental Clearance, where required
• T&TEC — setbacks from high-voltage lines
• WASA — water and wastewater matters (see our WASA approval guide)

A straightforward house on an approved lot will not involve all of these. A sloping site near a river, or a commercial building, may involve several.

Planning permission is not a building permit

These are two different approvals from two different bodies, and you need both:

• Planning permission (TCPD) approves the use and development of the land.
• Building approval (your Municipal Corporation) approves the building plans themselves. Under the Municipal Corporations Act, it is an offence to erect or alter a building without having its plans approved by the Council, or to build contrary to the approved plans.

Through DevelopTT, once TCPD approves an application it is forwarded to the relevant Municipal Corporation, which handles the building permit, inspections and, at the end, the completion certificate. Construction should not begin until the building permit is issued. Building permit fees are set by the Municipal Corporation.

What happens after you submit

1. Completeness checkThe application is checked for the required documents and may be queried if something is missing.
2. AssessmentPlanners consider land-use policy, development plans, site standards, the design, nearby permissions and site investigations.
3. Agency inputOther agencies review or advise where the project requires it.
4. DecisionPermission may be granted, granted with conditions, or refused. Reasons must be given in writing for a refusal or for conditions.
5. Building permitAn approved application moves to the Municipal Corporation for building approval before construction.

The General Development Order sets a two-month period for a decision, which can be extended by agreement in writing. How long a particular application takes depends on its complexity, the agencies involved and whether anything is queried — no one can promise a timeframe.

Build what was approved. If the finished building differs from the approved plans, the permission may no longer cover it, and a new application may be needed.

If an application is refused

You can revise the proposal to address the reasons given and submit again. The Town and Country Planning Division also describes a route for requesting a Ministerial review of a decision, through the Advisory Town Planning Panel.

A note on Tobago

The Town and Country Planning Division has a Tobago Regional Office, and DevelopTT has been used for planning applications processed there since 2023. Divisions of the Tobago House of Assembly handle approvals similar to those of the Municipal Corporations in Trinidad, including building permits and public health approval. If you are building in Tobago, confirm the current process with the Tobago office.

Why every project is different

Two houses of the same size can follow quite different approval paths. The land's approved use, whether it is part of an approved subdivision, its slope, its drainage, its access, and whether it is state or private land can all change what's required. This guide explains the general process; it isn't a substitute for checking the requirements for your own site.
