Avery Construction is a construction company, that is based in Grand Theft Auto: Vice City and Grand Theft Auto: San Andreas. The company may likely be based in San Andreas as the company is working out of Blueberry, Red County, San Andreas. Its unknown if the company may be linked to Avery Carrington as the name has the word "Avery" in it and a billboard of Carrington on it can be seen in Las Venturas.
In GTA Vice City, its possible that the business is runned from Avery's building that is under construction in Vice Point.
