How much you can increase rent for an extra tenant depends heavily on local laws (like rent control in LA or San Jose, which might cap it at 5-10%) versus general market rules, but common methods are a flat fee ($20-$100/month) or a percentage (10-20%), often requiring a new lease or agreement to formalize, with landlords citing increased wear and tear as justification.
