Medium-stay business rentals are arguably the most profitable and least understood segment of French Guiana’s rental market. While many owners chase nightly tourists, hundreds of Guiana Space Centre subcontractors, Ariane 6 launch-campaign engineers and government agents on assignment are looking for a furnished home for 1 to 10 months — and don’t always find one. After several years managing properties between Cayenne, Kourou and Remire-Montjoly, here is how to pivot toward this clientele, at what rates and within what legal framework.
Why medium-stay business rentals are the real market in French Guiana
Let’s be honest: French Guiana is not Martinique. Tourist traffic remains limited, concentrated in the dry season (mid-July to mid-November) and a few highlights such as launches from Kourou. The territory, however, runs to the rhythm of professional assignments.
In concrete terms, who is looking for a furnished home for several weeks or months in French Guiana?
- Space-industry subcontractors: ArianeGroup, Telespazio, CNES and dozens of SMEs send teams to Kourou for Ariane 6 and Vega launch campaigns — 4 to 8 weeks, often extended by weather-related postponements.
- Government missions: magistrates, gendarmes, teachers, hospital managers from the CHC in Cayenne, generally for 3 to 12 months.
- Construction and energy: EDF worksites, housing programmes in Matoury and Macouria, site managers on long assignments.
- Locum healthcare staff: nurses and substitute doctors seeking studios and one-bedroom flats near Cayenne for 1 to 3 months.
This demand is spread across the whole year, barely affected by the rainy season, and driven by companies that pay well and fast. The ideal tenant profile.
Housing CSG employees: what space-industry companies really look for
Housing for CSG employees follows precise criteria that come up mission after mission. If your property ticks these boxes, you stand out.
Location: the Kourou – Cayenne – Remire-Montjoly triangle
- Kourou remains the ideal base: 10–15 minutes from the Space Centre, with sought-after neighbourhoods around Lake Bois Diable and the seafront. A short home-to-CSG commute makes all the difference for teams working shifted hours, since launch countdowns sometimes run through the night.
- Cayenne and Remire-Montjoly capture administrative and hospital missions, as well as managers who commute to Kourou (60 km, about 50 minutes via the RN1). Remire-Montjoly, with its beaches, is the favourite municipality for long assignments.
- Matoury plays the proximity card with Félix-Éboué airport: handy for rotations to Paris (direct flight, a -5h time difference in winter, -6h in summer).
Non-negotiable amenities
- Air conditioning in every bedroom (not just the living room): the number-one criterion all year round.
- Fibre Wi-Fi: video calls with mainland France happen early in the morning because of the time difference.
- Washing machine: in the rainy season, laundry won’t dry outdoors.
- Secure parking: every tenant arrives with a rental car.
- A proper bed and a real desk: a 2-month stay is not lived on a sofa bed.
- Window mosquito screens: a local detail that reassures first-time arrivals.
A furnished one- or two-bedroom flat that combines all this in Kourou rents for €1,100 to €1,600 per month, utilities included as a medium stay, versus €750 to €950 unfurnished. In Cayenne and Remire-Montjoly, expect €1,200 to €1,800 per month, and up to €2,200 for a villa intended for a manager with family.
The mobility lease in French Guiana: a legal framework tailored to this market
The mobility lease (ELAN law) is the perfect tool for this clientele, and it remains underused here:
- Term of 1 to 10 months, non-renewable: exactly the format of space and administrative missions.
- Reserved for tenants in professional mobility (assignment, transfer, training): your target precisely.
- No security deposit may be required — but the Visale guarantee covers unpaid rent free of charge.
- One-month notice from the tenant, no automatic renewal: you recover your property on a known date.
- Furnished accommodation mandatory within the meaning of the 2015 decree.
In practice, I recommend a hybrid strategy: a mobility lease for stays of 1 to 10 months, and seasonal rental to fill the gaps in the dry season, when visitors come for the Salvation Islands, the Kaw marsh or the Maroni river by pirogue. Our complete French Guiana guide details these tourist highlights.
Company invoicing: the detail that changes everything
Space-industry companies house their teams via purchase orders. To capture this flow, offer a clear monthly invoice, accept 30-day bank transfers and allow flexibility on dates: an Ariane 6 launch postponement can extend a stay by 2 weeks overnight. The owner who says yes that day keeps the client for every subsequent campaign.
Long-term rental in Kourou: rates, returns and pitfalls to avoid
Let’s talk numbers for long-term rental in Kourou, where the pivot is justified or not.
A realistic simulation on a furnished two-bedroom flat in Kourou
- Classic unfurnished rental: €850/month, i.e. €10,200/year, with the risk of unpaid rent and a 3-year lease.
- Medium-stay business: €1,400/month utilities included, a realistic occupancy of 9.5 months out of 12: €13,300/year, solvent tenants, the property handed back between each mission.
- Hybrid medium-stay + seasonal in the dry season (€85–110 per night): €14,500 to €16,000/year.
The extra income is paid for in management: frequent inventory checks, professional cleaning between missions (€60 to €90 per turnover for a two-bedroom), laundry, responsiveness. This is the work of a local concierge service.
The classic mistakes of owners just starting out
- Underestimating wear and tear: a home occupied 11 months out of 12 ages quickly in this climate; budget 5% of rent for upkeep (AC serviced twice a year, about €80 per split unit).
- Neglecting insurance: check that your non-occupant landlord policy covers short- and medium-term furnished rental.
- Ignoring LMNP taxation: the actual-expenses regime with depreciation often wipes out tax on rents for years.
- Staying invisible to companies: principals don’t search on tourist platforms; they go through local contacts and identified managers.

FAQ
What is the maximum duration of a mobility lease in French Guiana?
A mobility lease lasts from 1 to 10 months, with no possible renewal with the same tenant. It applies in French Guiana just as in mainland France, the territory being a French department. Beyond 10 months, you must switch to a classic one-year furnished lease.
What rent should I charge in Kourou to house CSG subcontractors?
In 2026, a well-located furnished and air-conditioned one-bedroom flat in Kourou rents for €1,100 to €1,400 per month utilities included as a medium stay, a two-bedroom for €1,300 to €1,600, and a family villa for €1,800 to €2,200 — provided you offer AC in every bedroom, fibre, parking and a monthly invoice.
Can you combine tourist seasonal rental and medium-stay business?
Yes, and it is in fact the most profitable strategy in French Guiana: reserve the dry season (mid-July to mid-November) for tourists coming for the Space Centre, the Salvation Islands or the turtles of Awala-Yalimapo, and fill the rest of the year with professional missions on a mobility lease.
Do tenants on assignment need to be vaccinated against yellow fever?
Yes, the yellow fever vaccine is mandatory for anyone staying in French Guiana, professionals on assignment included. The employer generally ensures this before departure, but a savvy manager mentions it in the arrival guide, along with the other practical information (dialling code +594, time difference, a car being essential).
