We consider a sphere of 7.5 Mpc radius, which contains 355 galaxies with accurately measured distances, to detect the nearest empty volumes. Using a simple void detection algorithm, we found six large (mini)voids in Aquila, Eridanus, Leo, Vela, Cepheus, and Octans, each of more than 30 Mpc³. In addition, 24 middle-sized ``bubbles'' of more than 5 Mpc<sup>3</sup> volume are detected, as well as 52 small ``pores.'' The six largest minivoids occupy 58% of the considered volume. The addition of the bubbles and pores to them increases the total empty volume up to 75% and 81%, respectively. The detected local voids look like oblong potatoes with typical axial ratios b/a=0.75 and c/a=0.62 (in the triaxial ellipsoid approximation). Being arranged by the size of their volume, local voids follow a power law for volume-rank dependence. A correlation Gamma function of the Local Volume galaxies follows a power law with a formally calculated fractal dimension D=1.5. We found that galaxies surrounding the local minivoids do not differ significantly from other nearby galaxies in their luminosity, but have appreciably higher hydrogen mass-to-luminosity ratios and also higher star formation rates. We recognize an effect of the local expansion of a typical minivoid to be ΔH/H₀~(25±15)%.
