Updated October 11, 2022: We are providing updates to provide you with additional information. Thank you for your patience.
We would like to provide clarification on the enforcement of maximum count of lists and libraries per site. As described in the SharePoint limits - Service Descriptions, the service limit is 2,000 lists and libraries combined per site collection (including the main site and any subsites). Beginning February 2023, we will enforce the limit of 2,000 lists and libraries independently at the main (root) site and the subsite level. For instance, a site collection can have 2,000 subsites (including the main site) and each subsite (including the main site) could have 2,000 lists and libraries (including the hidden and default out of the box libraries).
These limits may get further re-aligned based on the service description in the future, but the timeline is TBD. In the meantime, we still recommend customers to follow the limits defined in the service description to achieve the best performance and service reliability.
SharePoint recommends a maximum of 2,000 lists and libraries per site, and 2,000 subsites per site. These have been long standing limits for SharePoint but have not been formally enforced.

There have been cases where some sites exceeded these limits, resulting in poor site performance and low-quality viewing experience. One of the most impacted areas is the API performance that degrades significantly when users access data on the sites that exceed their recommended limits. The API calls may time out or get throttled, blocking the users from opening the site or resulting in unexpected failures. In some extreme cases, the issue can impact functionalities beyond these sites.
To ensure site performance and help customers have the best possible experience, Microsoft will implement a safeguard to prevent customers from exceeding these limits.
[When will this happen:]
The change will only impact the creation of new lists, libraries or subsites outside the approved limits starting in February 2023 (previously early November) and will be completely enforced by late April (previously late December).

It is uncommon for the organic growth of site to reach these limits. However, there is a possibility that custom solutions can generate a high volume of lists and libraries. In that situation, our recommendation is to work with their solution providers to prepare an alternative solution in order to stay compliant with these limits.
