Public and Private Areas, Shared Jobsites, and Warrants Aimed at One Subcontractor

Attorney Answer

Public versus non-public decides most of it. Areas genuinely open to the public are accessible to agents on the same basis as anyone else; entering them is not a search (Maryland v. Macon), and 8 C.F.R. § 287.8(f)(4) says so expressly. Non-public areas - offices, enclosed work areas, locked containers - are protected: administrative entry into 'the portions of commercial premises which are not open to the public' requires consent or a warrant procedure (See v. City of Seattle; Marshall v. Barlow's), and § 287.8(f)(2) requires 'either a warrant or the consent of the owner or other person in control of the site.' Open ground is different: fences and 'No Trespassing' signs do not by themselves create Fourth Amendment protection in open fields (Oliver v. United States), while the interior of covered buildings is protected (Dow Chemical). Construction sites are not within the farm carve-out in § 287.8(f)(2) or 8 U.S.C. § 1357(e).

On a site controlled by a general contractor or homeowner, a subcontractor has no general veto. The closest case is a multi-contractor construction site: the owner and the other contractors with mutual use of the common areas could consent to an inspection over one contractor's objection, because that contractor 'cannot claim a reasonable expectation of privacy against these parties' (Donovan v. A.A. Beiro Construction). What a subcontractor keeps is its own interest in exclusive structures - its office, change shed, tool trailer, locked container (Mancusi v. DeForte on standing in one's own office). Say 'I do not consent on behalf of [company]' if that is accurate, identify the limits of your authority, and call counsel; do not assume your objection defeats another authorized person's consent or a warrant, and never physically interfere. The present-objector rule of Georgia v. Randolph is limited to a shared dwelling and does not transfer to a jobsite.

A warrant 'aimed at one subcontractor' can still authorize entry into the areas it describes. A judicial warrant for a business search need not name every worker if it is specific as to place, time and scope (Blackie's House of Beef v. Castillo, D.C. Cir.; note that a Ninth Circuit district court declined that decision's relaxed probable-cause standard, so do not present it as settled for Arizona or Nevada). An arrest warrant for a person is not a search warrant for someone else's private premises (Steagald, a home case applied here by analogy), and an ICE administrative warrant raises the issues in the next answer. Ask for a copy, identify the scope, state accurate non-consent, document any overreach, and let counsel litigate it later.
