PRB-1 · antenna siting · local zoning · mobile-radio law
Amateur radio is federally licensed, but antennas still live on real property, beside streets, under state statutes, and inside local zoning systems. This page keeps those layers separate instead of pretending one citation magically erases the others.
The useful question is not “Is ham radio legal?” It is “Which rule governs this particular antenna, place, vehicle and use?”
The FCC’s PRB-1 policy is a limited preemption of state and local antenna regulation. Section 97.15(b) says state and local rules may not preclude amateur-service communications; they must reasonably accommodate amateur communications and use the minimum practicable regulation needed to accomplish a legitimate local purpose.
That is a meaningful protection, but it is not a blanket exemption from zoning, setbacks, building and safety rules, public-right-of-way controls, or permitting. PRB-1 also does not itself preempt private deed restrictions or CC&Rs.
State antenna protections
These provisions sit on top of the federal baseline. They do not turn every proposed installation into an automatic permit.
California
City and county antenna ordinances must allow heights and dimensions sufficient for amateur communications, must not preclude those communications, must reasonably accommodate them, and must be the minimum practicable regulation for the local purpose.
California LegislatureCurrent statutory textWashington
Washington separately directs cities/towns and counties to conform amateur-antenna regulation to PRB-1’s reasonable-accommodation and minimum-practicable-regulation standard.
Oregon
Health, safety or aesthetic rules governing placement, screening or height must reasonably accommodate amateur communications and be the minimum practicable regulation. Oregon also bars a 70-foot-or-lower cap unless that restriction is necessary to achieve a clearly defined health, safety or aesthetic objective.
Oregon LegislatureSee ORS 221.295Nevada
Nevada expressly incorporates § 97.15 and PRB-1. Local health, safety or aesthetic siting rules must reasonably accommodate amateur communications and use the minimum practicable level of regulation; a conflicting local action is void, subject to the statute’s historic/architectural-preservation exception.

Local code is where abstract preemption meets an actual lot line, yard and right-of-way.
Chico, California
Chico Municipal Code § 19.78.040 treats a ground-, roof- or building-mounted antenna operated by a federally licensed amateur as exempt from Chapter 19.78 when it is on a previously developed site, does not exceed 40 feet, is not in front or side-yard setbacks, and satisfies the stated RF-compliance conditions.
For detached residential accessory uses, Table 5-9 in § 19.76.020 lists ground-based antennas with a 3-foot side setback, the street-side setback required for the main structure, and a 3-foot rear setback. The same table states that a structure, projection or equipment may not occur beyond the parcel’s property lines.
Separate public-space rules still matter. Chico’s street-tree rule, § 14.40.320, prohibits attaching a rope, wire or other contrivance to a tree or plant. Work or an encroachment in, under or over City right-of-way can also trigger Chapter 14.08 permitting. Those provisions are listed here without converting them into a parcel-specific conclusion.
Bremerton, Washington
Bremerton is subject to Washington’s city/town PRB-1 implementation in RCW 35.21.315. The City’s zoning code and official zoning map were updated in 2025. A review of the current online zoning materials did not surface a dedicated amateur-radio provision equivalent to Chico’s 40-foot exemption, so an installation should be checked against the current parcel zoning and with Community Development rather than inferring a local height or setback that the code search did not establish.
Mobile operation
The radio may be the same when the state line changes. The statute is not.
California
Vehicle Code § 23123.5 prohibits driving while holding and operating a handheld wireless telephone or electronic wireless communications device unless used in the hands-free manner the statute permits. The section does not contain the explicit amateur-radio exclusion found in Washington law. K6RCS therefore uses a driver-first, mounted/managed-control posture and does not publish a categorical California ham-radio exemption.
CVC § 23123.5California LegislatureWashington
RCW 46.61.672 defines “personal electronic device” so that it does not include two-way radio, citizens band radio or amateur radio equipment. The statute also treats temporary stops in traffic as driving; a vehicle safely pulled off the active roadway is treated differently.
RCW 46.61.672Current Washington text, including 2026 amendmentOregon
ORS 811.507 provides an affirmative defense for a driver age 18 or older who holds a valid amateur-radio or other FCC license and was operating an amateur radio. “Affirmative defense” is not the same procedural creature as an activity excluded from the statute’s definition, so the distinction is worth preserving.
ORS 811.507See subsection (4)(e)Nevada
NRS 484B.165 excludes certain two-way-radio devices from its “handheld wireless communications device” definition when the main controls are on a separate transmit/receive unit and only the microphone/PTT is held. Separately, the statute’s express amateur-operator exception applies to disaster or emergency communications, drills/tests/exercises, or communicating public information. Routine mobile operation should not be described as though that emergency-oriented exception were unlimited.
