How do I mail letters to my landlord?

Put repair requests, rent disputes, move-out notices, and deposit claims in writing and send them so you can prove delivery. For anything friendly or routine, regular mail is fine; for anything contentious: withheld deposits, ignored repairs, rent-increase fights: use tracked mail (US Certified Mail or Canada Registered Mail) and keep a copy of exactly what you sent.

Why does a paper trail matter with a landlord?

Phone calls and hallway conversations evaporate. Six months later, when your deposit is short $400 for "cleaning," your memory of a verbal promise is worth nothing and the landlord's memory will conveniently differ. A dated letter creates a record that exists outside anyone's memory, and in many jurisdictions, a landlord's legal clock for fixing a problem or returning a deposit starts running when they receive your written notice, not when you first mentioned it out loud.

Tracked mail adds the second half: proof the notice arrived. A landlord who ignores your letter cannot later claim they never got it when you hold a signed delivery receipt. That single piece of paper is often what turns a ignored complaint into a settled one, because it signals you are building a file, not just venting.

Which letters should you always put in writing?

What details make a landlord letter effective?

Three small habits separate letters that work from letters that get filed away. First, date the letter itself, not just the envelope: envelopes get thrown out, and an undated letter is much weaker evidence. Second, state your unit number and the property address; landlords with multiple buildings route mail by unit, and a letter without one can sit on a desk for weeks. Third, for move-out and deposit letters, include your forwarding address in the letter body. It closes the classic excuse: "I didn't know where to send the deposit": before it can be used.

One timing trap: notice periods usually run by the rental period, not the calendar month. If your tenancy runs from the 1st and you give notice on the 5th, many jurisdictions count that as notice for the following month: costing you a full extra month of rent. Check your lease and your local rules before you pick the date on the letter.

Do the rules vary by province or state?

Yes: substantially. Notice periods, deposit limits and return deadlines, repair obligations, and even whether email counts as valid notice all differ across provinces and states, and some places require specific government forms for certain notices. Rules vary by province/state: check yours before you rely on any deadline mentioned here. Your province or state's tenancy board or attorney general's tenant guide is the authoritative source, and most publish plain-language versions online.

This is general information, not legal advice.
