Can a Landlord Charge for Smoke Detectors or Batteries?

Smoke detector claims often involve missing units or batteries. Learn what's reasonable, what to ask for, and how to dispute charges that look like maintenance.

1 min readUpdated January 2026

Smoke detectors are safety devices, and landlords sometimes charge tenants for missing detectors, missing covers, or battery replacement. Disputes focus on proof of missing equipment versus routine battery maintenance.

When the charge can be legitimate

  • A detector was removed/missing at move-out (documented)
  • A detector was damaged by tenant actions
  • The charge is for actual replacement cost and is documented

Red flags

  • Charging for battery replacement as a move-out deduction without proof
  • No photos showing missing/damaged detectors
  • Inflated "hardware" charges without receipts

What to ask for

  • Photos showing missing/damaged detector and location
  • Replacement receipt/invoice for detector hardware
  • Inspection notes from move-out walkthrough

How to dispute

  1. Request photos and replacement receipts for any claimed missing detectors.
  2. Dispute routine battery replacement billed as tenant damage.
  3. Attach your move-out photos showing detectors in place (if you have them).

Start with the dispute template, then escalate to a demand letter if the landlord won't correct it.

Tip: Use the Deduction Checker to sanity-check how the landlord calculated the charge.
