Bradford Bulls will play their “home” games at Dewsbury Rams' Tetley’s Stadium for the 2020 and 2021 seasons.
Subject to RFL approval the Bulls will leave Odsal, their home ground for 85 years, on September 1.
Chairman Andrew Chalmers blamed the cost of rates, rent and maintenance for the decision in a statement, and said the club are in discussions about potential sites for a new-build stadium in Bradford.
In the meantime, the Bulls will move their matchday operations to Dewsbury's 5,100-capacity stadium.
Rams chairman Mark Sawyer said: “It is important that we help such an iconic club as Bradford through this transitional period. We have negotiated mutually acceptable terms for the use of the Tetley’s Stadium as well as protecting our own interests in this two-year period.
“Our current capacity is capable of coping with the demands of Championship rugby league and should the Bulls be successful in obtaining promotion then we already have plans on how the ground capacity can be increased to meet Super League standards.”
“We hope our own supporters will welcome this move since it helps to underpin what we are doing here at Dewsbury as well as providing a sustainable basis for Bradford.”
Ironically, the Rams' next home game is against Bradford on Sunday (3pm).
The Rugby Football League own the leasehold for Osdal Stadium following the Bradford club's financial collapse in 2012.
Bulls chairman Andrew Chalmers said in a statement: "I believe this decision is firmly in the best long-term interests of the club.
"[It] provides financial sustainability, protects the history and legacy of the Bradford Bulls, and allows the Bulls to focus on developing young rugby talent through our Tong high performance academy, under the careful eye of our coaching and development staff.
"The fact that no deal was able to be agreed with the Bradford City Council and the Rugby Football League, isn't a reflection on the hard working efforts of the executive officers of both organisations. But the fact remains as I clearly outlined - that doing the same thing over and over again and expecting a different result, wasn't going to happen."
An RFL statement read: "Bradford's request to use the Tetley's Stadium as a home ground remains subject to the approval of the RFL Board, who are charged with making a decision in the best interests of the sport.
"We have not received an application, and it would be inappropriate for us to comment until we do."
