When you rent an apartment in Paris there will probably be a small clause that defines a yearly rent increase. It’s your responsibility to keep track of this and increase your rent payments on the anniversary of your apartment rental.
Most people, like myself, discover this the hard way when they move and find a bill for the backdated rent increase.
This is actually a pretty reasonable function. It removes the arbitrary rental increases and uses a schedule developed by the French government. My apartment that cost 1,250 euros/month had a rent increase last year of 55 euros/month. I’m not sure how that relates to other cities, but I thought it was reasonable and similar to what you’d pay in California.
