NGC 4699 is a Seyfert like galaxy with very weak nuclear emission. The galaxy features a bar that is 0.41 arcminutes long and a ring with diameter 1.95 arcminutes. The galaxy features a large bulge which accounts for the 11.3% of the stellar mass of the galaxy and a large disky pseudobulge, which is larger than the strong bar. The disk within the bulge features tightly wrapped spiral arms. There are a lot of HII regions in the disk.  The galaxy has an extended type-III outer disk, with low central surface magnitude and which is thicker than the inner disk.
