US law has no general deemed-permit doctrine
Korean and Japanese administrative law lets a main permit carry related permits with it, and treats silence by a consulted agency as consent. United States federal law has no equivalent general rule. Each permit is applied for separately, and agency silence normally means nothing at all. The closest federal analogue is the wireless facility shot clock, where Congress and the FCC fixed review periods and, in one case, an automatic grant.
What the presets mean. Under 47 U.S.C. ยง1455(a) an eligible facilities request to modify an existing wireless tower must be approved within 60 days or it is deemed granted once the applicant gives written notice. Under 47 C.F.R. ยง1.6003 the FCC treats 90 days for a collocation and 150 days for new construction as presumptively reasonable; missing those clocks is a failure to act that the applicant challenges in court rather than an automatic approval. Some states have their own shot-clock or deemed-approved statutes for building and land use permits.
How the clock is counted. Counting starts the day after a complete application is filed, and the expiry date, total days and days remaining all use that same starting point. A timely incompleteness notice tolls the clock, so days you spend supplying missing material are added at the end. Figures are current as of September 2026 and should be checked against current FCC rules and your state code.

Frequently Asked Questions
No. Only the eligible facilities request route carries an automatic deemed grant. The other clocks create a presumption of unreasonable delay that is enforced in court.
A timely notice that the application is incomplete tolls it until the applicant supplies what was requested. This tool adds those tolled days to the end of the review period.
