How does a new presidential administration change federal regulations?

Administration transitions reshape the regulatory landscape predictably. Three near-immediate actions typically follow inauguration: (1) a "regulatory freeze" memo halting rules that haven't yet been published in the Federal Register and delaying effective dates of recently published rules, (2) withdrawal of pending rules from OIRA review, and (3) reissuance or revocation of executive orders governing the rulemaking process itself (e.g., EO 12866, EO 13771, EO 14094, EO 13891).

Slower-track changes: the new Unified Agenda (typically published 90–120 days after inauguration) reveals new priorities; political appointees take 6–12 months to confirm and staff up; agency rescissions and replacements require new notice-and-comment rulemaking, which takes 12–24 months minimum.

The Congressional Review Act gives Congress 60 legislative days from a final rule's submission to pass a joint resolution of disapproval — sweeping out late-term rules from the prior administration. CRA resolutions need only a simple Senate majority (no filibuster) and presidential signature. The "lookback window" for late-term rules typically extends 60 legislative days back from inauguration.

For small businesses: expect significant policy direction shifts in EPA, DOL, FTC, NLRB, CFPB, and SEC enforcement; relatively less change in technical rules at FDA, FAA, FCC, and FMCSA. Track the new president's "Day One" executive orders — they signal which categories of rules will move fastest.
