- The brokerage logo must appear near the top of the site. Footer-only placement is not acceptable.
Intermountain MLS
When adding the Intermountain MLS feed to an already active and live account:
- Intermountain MLS may grant temporary approval so the site can undergo compliance review.

- The feed may remain active, or
- The feed must be disabled until compliance adjustments are completed.
Important Notes
- Compliance requirements may change at the discretion of the MLS.
- Some MLSs may require additional revisions before final approval.
- If unsure whether a staging domain is acceptable, verify with the MLS before submitting for review.
