Investing in rental property in Bayonne in 2026
In short
Bayonne is the most tightly regulated market in this guide. Rents are capped twice over — Basque Country reference rents and the tight-market cap on increases — and letting a second home to tourists requires a floor-area compensation, a scheme upheld by the Conseil d'État in June 2026. The result: around €4,300/m² in the older stock for a gross yield of 3.5% to 4.5%. The ranges below are orders of magnitude — cross-check them against official data before any decision.
The rental market in Bayonne
Below are order-of-magnitude ranges for Bayonne. They are indicative and must be cross-checked against official data (DVF, ANIL rent observatory) before any decision.
| Metric | Indicative range (order of magnitude) |
|---|---|
| Purchase price (existing stock) | 3,200 – 5,300 €/m² |
| Rent (incl. charges) | 11 – 15 €/m² |
| Gross yield | 3.5 – 4.5 % |
| Population (approx.) | ≈ 54 000 inhabitants |
The city-wide average sits at around 4,300 €/m² for existing stock. The purchase-price range above is wider because it spans every neighbourhood, from the most affordable to the city centre — read it as the spread between areas, not as a bracket around the average.
Reference neighbourhoods
Within Bayonne, prices and yields vary widely from one area to another. A few reference points:
- Arènes / Allées Marines — the most expensive, along the Adour towards Anglet, families and executives
- Beyris / Polo-Beyris – Saint-Amand — suburban south, the only clearly rising area, social pockets to distinguish
- Saint-Léon / Marracq — near the Nive campus and secondary schools, students and young professionals
- Mousserolles — residential east, the widest gap between sources — treat the price with care
- Grand Bayonne — pedestrian historic core, protected heritage area, constrained works
- Petit-Bayonne — 77% tenants, the city's most rental-driven area, night-time noise
- Saint-Bernard — quiet residential area, low tenant turnover
- Saint-Esprit — right bank around the station, target of the Adour right-bank project
- Sainte-Croix / Saint-Frédéric — the cheapest area, extreme price dispersion, select street by street

The strongest rental markets in Bayonne
In Bayonne the regulatory framework matters more than the choice of product: it sets the achievable rent and closes off an entire strategy. Here is what that changes, segment by segment.
Basque Country rent caps: Bayonne is covered
Bayonne is one of the 24 municipalities of the Basque Country agglomeration subject to rent-level caps since 25 November 2024. The prefectoral order in force, published on 28 October 2025, applies to leases signed or renewed from 25 November 2025 to 24 November 2026. Each year the prefect sets, by sector, property type, number of rooms, construction period and furnished or unfurnished status: a reference rent, a reference rent increased by 20% which forms the legal ceiling, and a reference rent reduced by 30%. A rent supplement is possible only above the ceiling, for exceptional location or comfort features, and must be justified in the lease. Penalties reach €5,000 for an individual and €15,000 for a company, with repayment of rent wrongly collected. Ceilings can be checked on the official simulator hosted by the agglomeration.
Tourist lets: the compensation rule was upheld by the Conseil d'État
Since 1 March 2023 in Bayonne, letting a second home as a tourist rental requires a change-of-use authorisation together with a compensation: converting a non-residential premises of at least equivalent floor area into housing in the same municipality, or buying commercial-use rights. The ratio is one to one. On 11 June 2026 the Conseil d'État dismissed the appeals brought by FNAIM and ULMT 64, finding an overriding reason of general interest and judging the scheme proportionate: legal remedies are exhausted. Two exemptions remain: the owner's main residence, for two years and a single property, and above all the mixed lease combining a nine-month student let with a three-month tourist let, under a renewable annual authorisation. That is currently the only workable tourist arrangement in Bayonne for an investor.
Broad, year-round rental demand
Bayonne has 61.5% tenants and only 4.4% second homes: it is a primary-residence city, not a seaside resort, unlike Biarritz. It concentrates 36,345 jobs for 54,000 residents, an employment concentration index of 147.5 — it attracts one and a half times more workers than it houses. The industrial base sits at the city gates: Safran Helicopter Engines in Tarnos, Dassault Aviation in Anglet with 900 employees, Celsa France at the port, plus the Côte Basque hospital, the largest public employer. The port of Bayonne handled 2.16 million tonnes in 2025, up 2.3%. This permanent demand is the real foundation of the local rental market.
Students and the right bank: the two identifiable pockets
The Nive campus, in the city centre, brings together the UPPA's European and international studies college, the business administration institute and the Bayonne IUT, within a Basque university network that approached 8,000 students when the Campus Pays Basque initiative launched in 2023. No recent official figure broken down by site is published: caution is warranted on enrolment. Demand concentrates on Grand Bayonne, Petit-Bayonne and Saint-Léon–Marracq. In parallel, the Adour right-bank project covers 17 hectares between the Saint-Esprit and Henri-Grenet bridges, with a master plan delivered in late 2024 and first transitional buildings in 2026. It is the only documented upgrading lever for Saint-Esprit, today the cheapest sector — but the horizon is a decade and no housing programme has been quantified.
Regulatory framework: tight-market zone and the November 2026 deadline
Bayonne is also a tight-market zone: tenant notice reduced to one month, vacant-housing tax, possible surcharge on second-home council tax, and a cap on rent increases at re-letting. The two schemes stack: the tighter constraint applies. One point to know before buying: the rent-level experiment, created by the ELAN act and extended by the 3DS act, expires on 23 November 2026. Three scenarios are open — permanence, voted by the National Assembly in December 2025 but stalled in the Senate; abolition, sought by landlord organisations; or a transitional two-year extension limited to territories already engaged, announced by the government in late June 2026 and seen as the most likely. Nothing has been enacted to date: a financing plan in Bayonne should assume neither the survival nor the disappearance of the cap.
These reference points are an analysis and a decision-making aid, for information only. They replace neither the net-net yield calculation for a specific property, nor the support of a professional (chartered accountant, notary).
What net yield can you expect?
The gross yield is only a starting point. The net yield (after running costs) and the net-net yield (after tax) are what actually matter — and they depend on your tax regime, not on the city.
The right regime depends on your situation: bare or furnished letting, rent level, presence of a loan. RentValo compares every applicable regime for your property and shows the most advantageous one.

FAQ
What rental yield can you expect in Bayonne?
As an order of magnitude, gross yield sits in an indicative range of 3.5% to 4.5%, centred around 3.5-4%. Watch out for the most common calculation bias in this city: listing portals show prices 10-11% above the median of actual transactions and rents around 30% above the accredited observatory. Combining the two mechanically inflates yield. In Bayonne an advertised rent is not necessarily lawful either: it must be checked against the increased reference rent.
Are tourist lets still possible in Bayonne?
For a second home, they require a change-of-use authorisation with equivalent floor-area compensation in the same municipality, which is economically prohibitive. The Conseil d'État upheld the scheme on 11 June 2026: legal remedies are exhausted. Two routes remain without compensation: the owner's main residence, limited to one property and two years, and the mixed lease combining nine months of student letting with three months of tourist letting, under a renewable annual authorisation. A standard main residence may also be let up to 120 nights a year.
Which tax regime should you choose for a property in Bayonne?
The tax regime does not depend on the city but on your situation: letting type (bare or furnished), rent amount, presence of a loan, level of costs. In Grand Bayonne and Petit-Bayonne, old stock in a protected heritage area where works are heavy and constrained, the actual-expenses foncier regime and the déficit foncier are significant levers. On the mixed student lease, LMNP is the natural regime. RentValo compares every applicable regime and quantifies the gap for your specific project.
