Black residents, and they struggled to rebuild after the violence. Willows, the regional director of the Red Cross, noted this in his report, explaining his slow initial progress to facilitate the rehabilitation of the refugees. The fire code was officially intended to prevent another tragedy by banning wooden frame construction houses in place of previously burnt homes. A concession was granted to allow temporary wooden frame dwellings while a new building, which would meet the more restrictive fire code, was being constructed. This was quickly halted as residents within two weeks had started to erect full-sized wooden frame dwellings in contravention of the agreement. It took a further two-month delay to secure the court decision to reinstate the previous fire code. Willows heavily criticized the Tulsa city officials for interfering with his efforts, for their role in the Public Welfare Committee which first sought to rezone the "burned area" as industrial, and for constructing a union station in its place with no consideration for the refugees. Then he criticized them again for the dissolution of the Public Welfare Committee in favor of the formation of the Reconstruction Committee which failed to formulate a single plan, leaving the displaced residents prohibited from beginning reconstruction efforts for several months.

Tulsa's main industries at the time of the riot were banking (BOK Financial Corporation), administrative (PennWell, Oklahoma Natural Gas Company), and petroleum engineering services (Skelly Oil), earning Tulsa the title of "Oil Capital of the World". Joshua Cosden is also regarded as a founder of the city, having constructed the tallest building in Tulsa, the Cosden Building. The construction of the Cosden Building and Union Depot was overseen by the Manhattan Construction Company, which was based in Tulsa. Francis Rooney is the great-grandson and beneficiary of the estate of Laurence H. Rooney, founder of the Manhattan Construction Company. City planners immediately saw the fire that destroyed homes and businesses across Greenwood as a fortunate event for advancing their objectives, meanwhile showing a disregard for the welfare of affected residents.
