France 2026: The DPE Glow-Up, the Short-Term Rental Paperwork Party, and the Métro That Wants You to Move (Just a Little)

By Jay Corless, edited by Adrian Leeds

France has a unique way of starting the new year. The croissants stay the same, but the paperwork quietly changes overnight. Suddenly, everyone in the property market is talking about a coefficient, a registration number, or a Métro line that is “opening soon.”

Here’s our January 2026 reality check for expats, focusing on what really matters for your next move.

The first update is surprisingly interesting: the DPE (energy performance diagnostic) has been improved. Starting January 1, 2026, the electricity conversion factor in the DPE drops from 2.3 to 1.9. Simply put, homes with electric heating can now look much better on paper, even if nothing has changed in the apartment. If you’ve ever visited a cozy top-floor apartment and wondered, “This is adorable, but will it bankrupt me in winter?,” that question still matters, but the label might now show a different result than last year.

There’s another practical change that often surprises buyers: now, entire buildings are being examined, not just individual apartments. Since January 1, 2026, buildings with 50 units or fewer must meet the mandatory DPE “collectif” requirement, which already applied to larger buildings. If you’re looking at older Parisian properties, especially those built before 2013, expect more discussions about building-wide diagnostics and planned renovations, as these are now part of responsible ownership.

The second update is about short-term rentals. Many expats like the idea of occasionally renting out their place on Airbnb (or other short-term rental platform), either to help with costs or to stay connected to two places. However, France is making the rules stricter, and in 2026 this will be clear in two main ways. First, by May 20, 2026, every town hall must have an official registration process for “meublés de tourisme,” giving a registration number to declared units (Visit this website for Paris).

This doesn’t mean you can do short-term rentals just anywhere, but it does mean tracking and enforcement will be more consistent.

Second, the tax rules are now less favorable for some tourist rentals. For non-classified “meublés de tourisme,” the micro-BIC* threshold drops sharply to €15,000 (for income earned in 2025 and declared in 2026), with a lower allowance. If you were counting on the old ‘simple and lightly taxed’ approach, 2026 is the time to review your numbers, as the state has changed the calculations.

The third update is about Paris expanding its reach. The “Grand Paris Express” is one of the biggest projects changing how people live in the city. Official timelines still show new lines opening in stages from 2026, with Line 18 starting partial service this year and other lines following later. However, there have been some delays, including for Line 15 South and the first parts of Lines 16 and 17. For expats, this is less about commuting details and more about new possibilities: areas that once seemed too far away may now be great options, often offering more space and quieter streets for the same price.

Let’s talk about money, since it’s 2026 and no one likes surprises. Mortgage rates are not as low as they once were, but things are stable rather than unpredictable. As of January 6, 2026, one major rate source (CAFPI, or courtier en prêt immobilier et rachat de crédit) shows a 25-year average around 3.35%, and Meilleurtaux reports similar averages for January. Shorter terms are a bit lower, and longer terms a bit higher. These are not guaranteed rates—banks will still decide based on your profile—but for many buyers, the best approach is to have a strong application rather than wait for rates to drop.

Finally, here’s a reality check that is changing the rental market: energy rules are now being enforced. Since January 1, 2025, the worst-rated “passoires thermiques” (especially G-rated homes) face restrictions that often prevent them from being newly rented. This doesn’t mean tenants are forced out, but it does mean landlords are being pushed to upgrade or sell. If you’re renting, ask for documents early; if you’re buying, consider energy performance as a negotiation point, not just a formality.

So what’s the main takeaway, beyond all the paperwork? In 2026, the expat who succeeds in France isn’t the one who tries to time the market perfectly. It’s the one who pays attention to the details, uses the new rules to their advantage, and keeps an open mind during the first visit. Enjoy the lifestyle, but make sure the apartment is truly worth it.

If you’re visiting properties this month, try this simple approach: After asking yourself, “Do I love it,” ask “Will this place be good to me, on heating costs, paperwork, and resale?”

In 2026, that’s what separates a great experience from a pile of paperwork.

*Micro-BIC is a simplified French tax regime for people who earn commercial income (Bénéfices Industriels et Commerciaux—BIC), mainly from:

• Furnished rentals (locations meublées),
• Seasonal / short-term rentals (Airbnb, etc.),
• Small commercial activities (shops, services not classified as professional liberal). It allows you to declare gross turnover and benefit from a flat automatic deduction, instead of tracking and deducting real expenses.
