Results
The candidates for mayor and vice mayor with the highest number of votes wins the seat; they are voted separately, therefore, they may be of different parties when elected.

1st District
Vincent "Bingbong" Crisologo is the incumbent representative of the first district of Quezon City.

Crisologo filed a case in the Metropolitan Trial Court of Quezon City for the exclusion of candidate Vivienne Tan from the voter's list of the district, on the grounds that she was not a Filipino citizen when she registered as a voter, and she failed to meet the residency requirements under the law. Tan, the daughter of business magnate Lucio Tan, migrated to the United States and became a naturalized American citizen on January 19, 1993. She returned to the Philippines in 1996 and has resided here since. The court ruled in favor of Crisologo. Tan appealed and won in the Regional Trial Court (RTC), but Crisologo appealed to the Court of Appeals, which disqualified Tan as "Not being a Filipino citizen at the time of her application to be registered as a voter on October 26, 2009 or at the time when her said application was approved by the [Commission on Elections] on November 16, 2009, Tan's inclusion in the voter’s list of Precinct 0853-A, Barangay Santo Domingo, Quezon City, is therefore, highly irregular and downright invalid." The CA ruled in favor of Congressman Bingbong Crisologo. Further, Immigration Commissioner Marcelino Libanan certified that Tan re-acquired her Filipino citizenship only on December 1. On November 8, 2017, the Supreme Court of the Philippines affirmed the ruling of the Court of Appeals. The Supreme Court ruled that Tan was not a Filipino Citizenship at the time when she registered as a voter and thus her inclusion in the voter's list was highly irregular. Tan registered as a voter on October 26, 2009, before taking her Oath of Allegiance to the Republic of the Philippines on November 40, 2009. Under Philippine law, to be able to run for Congress, a candidate is required, among others, to be a natural born citizen of the Philippines, a registered voter in the district in which he or she shall be elected, and a resident thereof for a period of not less than one year immediately preceding the day of the election. The Supreme Court stated that she could not have been a registered voter since when she registered as a voter, she was not a Filipino Citizen. Thus it follows, that Tan could not be a candidate for Congress since she was not a registered voter in the district where she intended to run.
