About Regional Multiple Listing Service
Regional Multiple Listing Service (RMLS) is Portland's MLS and the listing backbone for most of Oregon, reaching across the Columbia into southwest Washington. Regional Multiple Listing Service IDX brings that two-state inventory to an agent's own website, and RMLS IDX searches from Pearl District condos to Hood River orchards all draw from this single system.
RMLS through the years:
- Launched in 1990, when listings still shipped as "The Book," a printed volume that stayed in demand until 1998
- Posted its first electronic listing in May 1991, covering five Portland-area counties at the start
- Grew to serve 21 of Oregon's 36 counties
- Crossed state lines by absorbing the Clark County Multiple Listing Service of Southwest Washington
- Governed by a shareholder board of NAR subscribers, with a Service Advisory Committee representing the wider membership
- Subscribers work in the RMLSweb platform
The Book-to-web arc says it plainly: this MLS has been shipping listing data to Portland agents in whatever format the era demanded for three and a half decades.
Coverage area
Regional Multiple Listing Service serves agents and brokers across:
- Oregon - Portland metro and most of the state: 21 of 36 counties
- Washington - the southwest corner, Clark County and the Vancouver market
Recognizable territory:
- Portland metro: Multnomah, Washington, and Clackamas counties, from St. Johns to Lake Oswego
- Vancouver, Washington: Clark County's commuter cities across the Columbia
- The north Willamette Valley: Yamhill wine country, Newberg, and McMinnville
- The Gorge and Mount Hood corridor: Hood River and the mountain towns
- Salem-adjacent and mid-valley markets where RMLS coverage meets the valley's own board
- Coastal and southern reaches shared with Oregon's regional systems
Central Oregon, the far south, and much of the coast run their own boards, all covered separately here. Seattle and Puget Sound belong to NWMLS, RMLS's northern neighbor.
How to get Regional Multiple Listing Service listings on your website
RMLS keeps a steady, well-worn data program, and CloseDaily manages the vendor side of it:
- Subscribe through RMLS. An active subscription plus broker sign-off is what RMLS needs from your side.
- Authorize your website. The MLS's IDX paperwork gets signed with broker sign-off, naming the site that will display listings.
- CloseDaily pulls the two-state feed. Oregon and southwest Washington listings arrive through one connection, handled on our accounts and agreements.
- Search opens under your brand. Map search, listing pages, and alerts, tuned to RMLS display rules, all delivered by CloseDaily.
The cross-river coverage is the practical prize: a Portland agent's site can serve Vancouver buyers without a second MLS membership, because the feed already speaks both states.
CloseDaily and Regional Multiple Listing Service
CloseDaily supports IDX integration for Regional Multiple Listing Service. RMLS data powers your search pages while the built-in CRM banks inquiries and keeps your follow-up on schedule.
Portland buyers weigh neighborhoods like careers and cross the river when the math says to. A site that searches both sides of the Columbia, and alerts them when a Felida listing hits, is how you hold both halves of that decision.
Monthly pricing starts at $299, and a credit card gets the 7-day free trial going. Once RMLS signs off, our onboarding work puts search live in a few business days.

Frequently asked questions
Does CloseDaily support Regional Multiple Listing Service IDX?
Yes. CloseDaily supports IDX integration for Regional Multiple Listing Service across Oregon and southwest Washington. We handle the authorization paperwork and feed connection during onboarding.
How do I add Regional Multiple Listing Service home search to my website?
Confirm your RMLS subscription, sign the website authorization with your broker, and CloseDaily does the rest. The two-state feed and the site build both land inside onboarding.
What areas does Regional Multiple Listing Service cover?
RMLS covers 21 of Oregon's 36 counties, centered on the Portland metro, plus Clark County in southwest Washington. Central Oregon, the southern counties, and much of the coast operate separate systems.
How long does Regional Multiple Listing Service IDX setup take?
RMLS authorization moves at broker-signature speed, and the feed work follows quickly. Plan on a few business days of onboarding after the MLS's approval.
Does RMLS cover Vancouver, Washington?
Yes. The former Clark County MLS of Southwest Washington merged into RMLS, so Vancouver, Camas, and the county's commuter cities list here rather than in the Seattle-area system. Puget Sound itself belongs to NWMLS.
What was The Book?
Before the web, RMLS published listings as a printed volume agents called The Book, launched with the MLS in 1990 and still in demand as late as 1998. The database your website taps today is the same operation, several formats later.
