> Looking to start subletting an apartment? Learn the rules, how to obtain landlord permission, and how to protect yourself legally in this guide.

Subletting an apartment is a common practice, but it is heavily regulated in Sweden. To avoid legal trouble, you must ensure you have a valid reason and the necessary permission from your landlord.

## The process of subletting an apartment
To start subletting an apartment, you must first secure written consent from your landlord. If they refuse without a valid reason, you have the right to appeal to the Rent Tribunal.

### Step 1: Identify a valid reason
Landlords typically approve subletting for reasons like studying abroad, working in another city, or cohabiting with a partner on a trial basis.

### Step 2: Request landlord permission
Always submit your request in writing. Keep a copy of the correspondence for your records.

### Step 3: Draft a legal contract
Ensure the contract covers the rental period, rent amount, and inventory. This protects both parties in case of disputes.

### Step 4: Manage the rental period
Be aware that subletting for more than two years can trigger specific legal protections for the tenant, so be precise with dates.

### Step 5: Set a reasonable rent
You are only allowed to charge the rent you pay yourself, plus a small percentage if the apartment is furnished. Charging more is illegal.

## Common FAQ
### Can I be evicted for unauthorized subletting?
Yes, subletting without permission is a breach of your lease and is grounds for immediate eviction.
### How do I calculate the rent?
Calculate your base rent and add a maximum of 10-15% if the unit is furnished. Do not exceed this to avoid legal issues.
### What is the difference between a subtenant and a lodger?
A subtenant rents the entire apartment while you are away, whereas a lodger lives with you while you are still present in the home.
