We present multi-component decomposition of high-quality $R$-band images of312 disk galaxies from the Carnegie-Irvine Galaxy Survey. In addition to bulgesand disks, we successfully model nuclei, bars, disk breaks, nuclear/innerlenses, and inner rings. Our modeling strategy treats nuclear rings and nuclearbars as part of the bulge component, while other features such as spiral arms,outer lenses, and outer rings are omitted from the fits because they are notcrucial for accurate bulge measurements. The error budget of bulge parametersincludes the uncertainties from sky level measurements and model assumptions.Comparison with multi-component decomposition from the \textit{Spitzer} Surveyof Stellar Structure in Galaxies reveals broad agreement for the majority ofthe overlapping galaxies, but for a considerable fraction of galaxies there aresignificant differences in bulge parameters caused by different strategies inmodel construction. We confirm that on average bulge prominence decreases fromearly to late-type disk galaxies, although the large scatter of bulge-to-totalratios in each morphological bin limits the application of Hubble type as anaccurate predictor of bulge-to-total ratio. In contrast with previous studiesclaiming that barred galaxies host weaker bulges, we find that barred andunbarred spiral galaxies have similar bulge prominence.
