We estimate the stable rank, connected stable rank and general stable rank of the multiplier algebras of $C^{*}$-algebras under some conditions and prove that the ranks of them are infinite. Moreover, we show that for any $\sigma$-unital subhomogeneous $C^{*}$-algebra, its stable rank is equal to that of its multiplier algebra.
