Weapons

Players Handbook (page 36)

The choice of weapons used by your character might be circumscribed by the class of your character, but selection is otherwise a matter of your preferences based on various factors presented hereafter. Of course, the initial cost of the weapon might affect your selection at the beginning. Beyond this consideration, there are factors of size and weight. The damage inflicted by the weapon is important, as is the amount of space required to wield it. These details are given hereafter.

House Rule

As defined on Equipping the Character your character will be limited by the weapons he/she carries at the start.
However, the initial number of weapon proficiencies, and penalty for non-proficiency still applies. So you must state the weapons you are proficient with, even though you may not initially possess one.
