How a Johnson County sex offender search works. Three things that make a search accurate.
Johnson County sex offender search by address: checking an address in Johnson County. Start from the street you care about, not the whole county.
A county is a big area; the useful question is usually one street. Start from the address you care about — a home you are buying or renting, a school, a daycare, a relative’s house — or its ZIP code, and set the radius to match: a few blocks for one home, a mile or two for a neighborhood.
Each result is the full registry record — photograph, offenses, the address last reported and the official record link. Radius search sees registrants whose published address we have placed on a map coordinate, so search a name as well when you are checking a particular person.

Johnson County sex offender records: reading a Johnson County result. What a record tells you, and what it does not.
Each Johnson County result is one registry record: the registrant’s name and aliases, a photograph, the address they last reported, the offenses that carry a registration duty and their current registration status, usually with a physical description and often a risk level or tier.
Two things it is not. It is not a full criminal history — offenses that never required registration do not appear, which is what a criminal record search covers. And the address is where the person last reported living, not proof of where they are today, so check the record date and confirm the photograph before acting on it.

How many registered sex offenders are in Johnson County?
As of October 2026, we index approximately 238 registrants with a Johnson County, IA address — about 15.6 per 10,000 residents, or about 1 in 642 residents. Treat the figure as scale rather than a fixed number: the registered population moves continuously as people are added, move, or are released from the requirement. When you need an answer about a specific person, run a search.
How does Johnson County compare with the rest of Iowa?
Johnson County sits at about 15.6 registrants we index per 10,000 residents, against a Iowa average of about 22.5 and a national average of about 47.2. Density varies block by block inside any county, so use the ratio as context — and a search, not an average, to answer about a specific address or person.
How do I check a specific person in Johnson County?
Type their last name and add whatever else you hold — first name, date of birth, or narrow to a Johnson County city or ZIP. You get scored matches with photographs and official record links, and the search covers every US registry at once, so someone now in Johnson County who was registered elsewhere still surfaces. Your first 25 searches are free, no card required.
How do I find sex offenders near a Johnson County address?
Search outward from a street address or ZIP within Johnson County. Each result is the full registry record — photograph, offense history and the official state link — and you can widen the radius from one mile to a hundred to cover a neighborhood or the whole area. It is address-and-radius search rather than a map, and it sees registrants whose published address we hold and have placed on a coordinate.
Is there a Johnson County sex offender list?
Yes — the list for Johnson County is a search: we index about 238 registrants with a Johnson County address, and narrowing a search to the county, one of its cities, or a ZIP code returns them with photographs and official record links. To keep an eye on a specific area rather than read a long list, search outward from an address instead.
Which Johnson County city has the most registered sex offenders?
We publish a page for one Johnson County city or none, so there is no city-by-city comparison here — search the county, a city, or a ZIP for the current picture.
Which counties border Johnson County?
Johnson County borders Cedar, Iowa, Linn, Louisa, Muscatine and Washington counties. A search here is not bounded by the county line: it covers every US registry at once, so someone registered just across a border still surfaces. Linn County has its own page here, with its own count.
Can I get alerts about sex offenders in Johnson County?
Yes. A location monitor watches an address and radius you choose in Johnson County and emails you when someone registered nearby is added or moves in, so you don't have to re-run the same search.
Is this the official Johnson County sex offender registry?
Registries are maintained per state, not per county, so no single official "Johnson County registry" list exists. What you search here is our continuously updated national dataset with every US registry in one place, and each record links back to the official state entry that published it — so you can verify any Johnson County result at its source.
