Frequently asked questions

What investment for a B&B in Saint-Denis?

Total investment 92K €-460K € €: property acquisition (60-75 %), renovation and compliance (15-25 %), fit-out and decoration (5-10 %), equipment (bedding, bathrooms, appliances) and launch marketing. Regional tourism aid and property tax breaks significantly reduce net cost.

What occupancy rate to reach in Saint-Denis?

Target: 50-60 % at cruise (200-220 nights/year per room). Strong seasonality (high season +30-50 %, low season -40-60 %). Multichannel distribution (Airbnb, Booking, Gîtes de France, direct site) smooths occupancy. Reaching 70 %+ implies repositioning toward business or events.

What legal obligations for a B&B?

Town hall declaration, optional prefecture classification (1-5 stars), private labels (Gîtes de France, Clévacances), professional liability insurance, ERP standards above 5 rooms, tourist tax remitted to municipality, income reporting under business or property income depending on activity level.

Which legal structure to favor?

1-2 rooms: passive rental income (favorable tax). 3+ rooms or primary activity: sole proprietorship, single-member LLC, or family real-estate company. Family LLC is interesting for estate transfer.
