Stadiums and locations
1 SpVgg Bayreuth will initially play their evening home matches at the Steigerwaldstadion since their home stadium, the Hans-Walter-Wild-Stadion, currently lacks floodlights. The club aims to fix this by the beginning of the season. 2 VfB Oldenburg will initially play their evening and winter home matches at the Heinz von Heiden-Arena since their home stadium, the Marschweg-Stadion, currently lacks floodlights and a heated pitch and is bound to noise regulation ordinances for matches after 18:30. The club aims to fix these problems and move back to Oldenburg as soon as possible. 3 SC Verl will play their home matches at the Home Deluxe Arena since their home stadium, the Sportclub Arena in Verl, does not meet 3. Liga standards.
