No, landlords generally cannot force you to remove a legitimate service dog simply due to a "no pets" policy, breed/weight restrictions, or preference. Service dogs qualify as a reasonable accommodation for disabilities, requiring housing providers to allow them in most rentals (with limited exemptions, such as certain small owner-occupied buildings). No pet fees, deposits, or extra rent apply.
A landlord can require removal only in limited cases:
The dog poses a direct threat to the health/safety of others (based on specific behavior, not breed stereotypes or speculation).
The dog causes substantial property damage that cannot be mitigated.
The accommodation imposes an undue financial or administrative burden (very rare for service dogs).
If your disability or the dog's trained tasks are obvious (e.g., a guide dog), no further documentation is needed. If not obvious, landlords may request reliable verification of your disability and the dog's necessity—but they cannot demand certification, registration, or task demonstrations.
