Yes, an Airbnb host has the right to refuse a booking request, but their refusal must comply with Airbnb's Non-Discrimination Policy. A host can decline a guest for several "valid" reasons, such as the guest having poor reviews from previous hosts, the guest's profile being incomplete, or the guest's specific needs (like pets or smoking) not aligning with the "House Rules." If a host uses "Instant Book," they can still cancel if they have a "valid safety concern" about the guest. However, it is strictly illegal and against Airbnb's terms to refuse a guest based on race, color, ethnicity, national origin, religion, sexual orientation, gender identity, or marital status. In 2026, Airbnb uses sophisticated AI monitoring to flag hosts who show a pattern of "discriminatory" declines. If a host is found to be refusing guests for discriminatory reasons, they can be permanently banned from the platform. Additionally, in certain jurisdictions, hosts must also follow local laws regarding service animals, which they generally cannot refuse even if they have a "no pets" policy.
