Iowa will accept a VA certification of disability in place of a physician statement for a disability parking permit. A veteran who received a vehicle through the VA automobile grant needs no permit at all, because the free regular plates carry the parking rights, but taking a military special plate instead gives that up.
Also called: Iowa Code 321L, 321L.2, disability parking, persons with disabilities parking permit, windshield placard, parking sticker, VA certification of disability, 321.105.
Two things in chapter 321L matter to a veteran and neither is obvious from the chapter's title.
VA certification can replace a physician statement. Section 321L.2, subsection 1 ordinarily requires a statement from a physician, physician assistant, advanced registered nurse practitioner, chiropractor, occupational therapist or physical therapist. Then: "The department may accept a certification of disability from the United States department of veterans affairs in lieu of a statement from a physician, physician assistant, advanced registered nurse practitioner, chiropractor, occupational therapist, or physical therapist. The department may adopt rules pursuant to chapter 17A detailing the requirements for an acceptable certification of disability."
That saves an appointment. It is permissive, so the Department of Transportation is not compelled to take your VA letter, and the rules govern what form of certification is acceptable. Ask before you pay for a provider visit.
The three permit forms. Subsection 1, paragraph "a" offers persons with disabilities registration plates ordered under section 321.34; a persons with disabilities parking sticker affixed to plates you already hold, bearing the international symbol of accessibility, available to an applicant who has plates under section 321.34 "or registration plates as a seriously disabled veteran under section 321.105"; and a removable windshield placard, temporary for up to six months or standard for five years, as the provider statement determines. A temporary placard must be renewed within thirty days of expiration.
The automobile grant route, and the trade-off. Section 321L.2, subsection 5: "A seriously disabled veteran who has been provided with an automobile or other vehicle by the United States government under the provisions of 38 U.S.C. §3901 – 3904 is not required to apply for a persons with disabilities parking permit under this section unless the veteran has been issued special registration plates or personalized plates for the vehicle. The regular registration plates issued for the disabled veteran's vehicle without fee pursuant to section 321.105 entitle the disabled veteran to all of the rights and privileges associated with persons with disabilities parking permits under this chapter."
Read the exception clause. The parking entitlement travels with the free regular plates. Order a Purple Heart plate, a veteran plate, or any personalized plate for that vehicle and the sentence turns off: you are then "required to apply for a persons with disabilities parking permit under this section" like anyone else. You do not lose the right to disability parking, because you can still apply. You lose the automatic entitlement and have to go and get a permit.
This is a real choice and it is made silently at the county treasurer's counter. A veteran with an automobile grant vehicle who wants a military plate should get the permit first, or get the parking sticker under paragraph "a" subparagraph (2), which is expressly available to a holder of section 321.105 plates.
Iowa is the fourth state in this catalog to draw the plate-and-parking line differently. Nevada grants free public parking to both the disabled veteran plate and the ex-prisoner of war plate under NRS 482.377, subsection 5. New Hampshire expressly denies free parking to its former prisoner of war, Purple Heart and Pearl Harbor plates under RSA 261:86, II while granting it to its amputee, paraplegic, permanently and totally disabled and total blindness plates. South Carolina grants it to its valour, Purple Heart, prisoner of war and Gold Star plates and, from October 6, 2026, denies it to its disability plate, when 2026 Act No. 115 repeals the older municipal meter exemption in S.C. Code § 56-5-2585. Iowa neither grants nor denies by valour: it attaches the entitlement to one specific fee-exempt plate and removes it if you swap. Four states, four rules, and the only one you can rely on is the one where you park.
What the permit does not get you. Chapter 321L is about designated parking spaces and the placard rules that go with them, not about free metered parking; section 321L.2, subsection 4 requires a removable placard to be displayed only when parked in a persons with disabilities parking space, entirely visible through the windshield, and removed from the mirror before driving. Municipal meter policy in Iowa is local.
One cross-reference worth checking against your own facts: a veteran who does not hold an automobile grant vehicle reaches disability parking the ordinary way, and the VA certification route in subsection 1 is what makes that straightforward. Rating percentage is not the test in chapter 321L; functional disability is.

Rule
A VA certification of disability may replace a provider statement
Iowa Code § 321L.2(1): the department "may accept a certification of disability from the United States department of veterans affairs" in lieu of a physician or other provider statement, subject to rules on acceptable form. It is permissive, so confirm before relying on it.
A VA automobile grant vehicle needs no permit, unless you order a special plate
Iowa Code § 321L.2(5). The free regular plates issued under § 321.105 carry all parking rights and privileges, but the entitlement turns off if special registration plates or personalized plates are issued for that vehicle.
A parking sticker is available to a § 321.105 plate holder
Iowa Code § 321L.2(1)(a)(2) allows a persons with disabilities parking sticker bearing the international symbol of accessibility to be affixed to plates issued under § 321.34 or to registration plates issued as a seriously disabled veteran under § 321.105.
No rating percentage is used in chapter 321L
The chapter turns on functional disability established by a provider statement or an accepted VA certification, not on a combined rating.
