The timing of a motion to compel depends largely on whether responses have been served. Here’s a review of the timing in common situations and a handy chart with the time limits.
If no responses served. If the responding party fails to serve any responses at all, there’s no time limit on when the propounding party may file a motion to compel responses. See, e.g., CCP §2030.290(b)–(c).
When responses inadequate. When inadequate responses have been served, a motion to compel further responses must be filed and served within 45 days of service of the responses or any supplemental responses, or on or before any date to which the parties agree in writing. Failure to do so waives the party’s ability to move for further responses. See, e.g., CCP §2030.300(c).
When deponent serves objections to business record subpoena. If the deponent serves objections to a subpoena to produce business records, the 60-day period during which a motion to compel must be filed begins to run when the deponent serves objections on the party that issued the subpoena. Rutledge v Hewlett-Packard Co. (2015) 238 CA4th 1164, 1192.
When deponent fails to appear or produce documents. If a deponent fails to appear or proceed with a deposition or produce things described in the deposition notice, there’s no time limit on when the party noticing the deposition may move to compel. CCP §2025.450(a).
When deponent fails to answer questions. A motion to compel answers at a deposition must be made within 60 days after the completion of the record of the deposition. CCP §2025.480(b).
When party refuses to submit to physical or mental examination. There’s no time limit on when a party may bring a motion to compel compliance with a demand for a physical or mental examination. CCP §2032.410.
Motion must be made no later than 60 days after the completion of the record of the deposition.
Motion must be made within 45 days of the service of the response, or any supplemental response, unless the parties agree in writing to a specific later date.
Motion must be made within 45 days of the service of the verified response, or any verified supplemental response, unless the parties agree in writing to a specific later date.
Keep in mind that all discovery motions must be heard at least 15 days before the date initially set for trial. CCP §2024.020(a).

Another superb post, Julie! Thank you so much! Love these notes.
