What are the lawful hours for retail sale of alcoholic beverages?

From 6 a.m. to 2 a.m. of the following day. In other words, it is unlawful to sell alcoholic beverages either by the drink or by the package, between the hours of 2 a.m. and 6 a.m. of the same day. It is also unlawful for any person to knowingly purchase any alcoholic beverages between the hours of 2:00 a.m. and 6:00 a.m. (Section 25631) ABC may further restrict the operating hours of licensed premises. Such restrictions may be imposed in the following situations:

1. If grounds exist for the denial of an application for a license or where a protest against the issuance of a license is filed and if ABC finds that those grounds may be removed by imposition of those conditions;
2. Where findings are made by ABC which would justify a suspension or revocation of a license, and where the imposition of a condition is reasonably related to those findings. In the case of a suspension, the conditions may be in lieu of or in addition to the suspension;
3. Where ABC issues an order suspending or revoking only a portion of the privileges to be exercised under the license;
4. Where findings are made by ABC that the licensee has failed to correct objectionable conditions within a reasonable time after receipt of notice to make corrections given pursuant to subdivision (e) of Section 24200.
