The oversized flag was draped over the east side of the building and will remain on display through the weekend, according to the office of Assembly Speaker Toni Atkins, D-San Diego.
The speaker received permission from Gov. Jerry Brown to display the flag to honor the gay and lesbian community, following the June 26 U.S. Supreme Court decision that legalized same-sex marriage nationwide.
The annual Spirit of Stonewall Rally, which commemorates a 1969 protest against police harassment in New York, is set to begin at 6 p.m. at Marston Point in Balboa Park. The fourth annual Pride of Hillcrest Block Party is scheduled to begin at the same time at the intersection of University Avenue and Normal Street.
The annual pride parade is set for Saturday at 11 a.m. along University Avenue in Hillcrest. A music festival will be held Saturday and Sunday in Balboa Park.
"Pride is for everyone -- whether you're a lesbian or gay or bisexual or transgender or a straight ally, we want everyone there,'' Stephen Whitburn of San Diego Pride said at a City Council meeting earlier this week. ``Pride is about having tens of thousands of people of all different stripes coming together to celebrate who they are and to celebrate each other.''
