Teams
Arenas
Like several Metro Manila-centric leagues, most games are held at arenas within Metro Manila, either the Smart Araneta Coliseum or the Mall of Asia Arena, and sometimes, in the Ynares Center in Antipolo. Games outside this area are called "out-of-town" games, and are usually played on Saturdays. Provincial arenas usually host one game, rarely two; these arenas typically host only once per season, but a league may return within a season if the turnout is satisfactory.
Typically, all playoff games are held in Metro Manila arenas, although playoff and Finals games have been seldom played in the provinces.

Notable events
Pre-season
November 2, 2017: The majority of the PBA Board of Governors passed a resolution stating that they will no longer support or endorse the renewal of Commissioner Chito Narvasa's tenure due to "loss of confidence". Representatives from Alaska, Blackwater, Meralco, NLEX, Rain or Shine, Phoenix and TNT attended a special board meeting on November 2 that passed this resolution. Deputy Commissioner and Technical Head Rickie Santos will be the league's officer-in-charge while the board will still tackle who will replace Narvasa as commissioner. Later in the afternoon, the bloc that composes the three San Miguel Corporation (SMC) teams (San Miguel, Barangay Ginebra and Star) as well as independent teams GlobalPort and Kia stated their continued support with Narvasa. Former PBA chairman Robert Non criticized the move done by the seven board members for making a "whimsical" decision in ousting Narvasa and mentioned that the move was unauthorized and non binding as per the league's by-laws. According to the PBA by-laws, a two-thirds vote of its current membership is necessary to remove or appoint a commissioner. Non also criticized the timing of the meeting when the meeting notice was only sent to all board representatives on Monday, October 30. According to the rules, the board representatives should have been notified seven days before the date set for the meeting. Narvasa later called a press conference at the PBA office in Libis and indicated that he will not resign as the commissioner. He is also requesting the seven teams that will not endorse his term renewal to explain the grounds of their "loss of confidence" to the current commissioner. He also stated that he is willing to resign the commissioner post, but after consultation with his family and lawyers, he will hold on as commissioner, given that any move to oust him should follow the rules stated in the league's by-laws. November 27, 2017: The Star Hotshots changed their name to Magnolia Hotshots. The team's new logo debuted during the team's press launching. December 11, 2017: The NLEX Road Warriors adopted a new logo. The new logo debuted during the team's press launching. December 17, 2017: PBA Commissioner Chito Narvasa officially tendered his resignation. The board of governors have advised Narvasa to stay as commissioner until December 31, 2017 to have a smooth transition to his eventual successor. The board also named Media Bureau chief Willie Marcial as the league's officer-in-charge.
