A Hanford seller preparing disclosures for a listing near the county fairgrounds types "airport noise disclosure Kings County" into a search bar and gets pages about F/A-18 Super Hornets, CNEL noise contours, and a Navy base that hosts the Pacific Fleet's entire strike fighter wing. None of it explains why their own transfer disclosure packet still carries a line about airport proximity. The seller closes the tab more confused than when they opened it.
The confusion is understandable. Naval Air Station Lemoore is the loudest, largest, most-discussed airfield in Kings County, and it dominates every search result. But NAS Lemoore sits roughly 14 to 19 miles west of Hanford, and the county's own zoning documents place its noise-sensitive Military Influence Area in "the northwest portion of the County," a description that lines up with Stratford and the rural land closest to the runways, not with residential Hanford. The airport that actually reaches into a Hanford disclosure packet most often is a different one entirely: Hanford Municipal Airport, a small general-aviation field on the city's own southeast edge.
Fourteen Miles Is Farther Than It Sounds
Kings County's general plan noise element is specific about where NAS Lemoore's jet noise actually lands. The county's most recent noise contour update for the base describes it as the most significant noise change in the county since the 1993 general plan, and it identifies Stratford as an area that may be almost entirely covered by 60 to 65 CNEL noise levels, a threshold that triggers mandatory mitigation for any new home built there. That's meaningful for property near the base. It's a different market than central Hanford, which sits well outside that contour.
The county's Military Influence Area tied to NAS Lemoore is described in the same planning documents as covering most of the northwest county, coordinated directly with base officials to manage land use around the runways. That geography puts the heaviest regulatory weight on Lemoore, Stratford, and the unincorporated farmland between them and the base, not on the city of Hanford itself.
The Airport That's a Few Minutes From Downtown
Hanford has its own airport, and it's nothing like NAS Lemoore. Hanford Municipal Airport, identified by the code HJO, sits on the southeast edge of the city and is owned and operated by the city itself. It's a general aviation facility with no commercial flights, home to roughly 70 based aircraft, including crop dusters that the county's own planning documents note can't land there while carrying agricultural chemicals due to environmental restrictions on chemical dumping. It is, by any measure, a quiet neighbor compared to a master jet base.
Because it's inside city limits, though, it's the airport whose compatibility zone actually overlaps with residential Hanford parcels. Kings County's development code creates a separate overlay for it, the Aviation Land Use Compatibility Overlay Zone, distinct from the overlay built around NAS Lemoore. The county code states plainly that this zone is applied within the compatibility areas around the Hanford Airport, a designation NAS Lemoore's overlay does not reach.
| NAS Lemoore | Hanford Municipal Airport (HJO) | |
|---|---|---|
| Distance from Hanford | Roughly 14 to 19 miles west | Inside city limits, southeast edge |
| Aircraft | F/A-18 Super Hornets, F-35C Lightning II | General aviation aircraft, including crop dusters |
| County overlay zone | Aviation Overlay Zone tied to the Military Influence Area | Aviation Land Use Compatibility Overlay Zone |
| Area most affected | Stratford and rural northwest county | Parcels near the airport's southeast edge |
| Public use | Military installation | City-owned, general aviation only |
What Actually Gets Recorded Against a Parcel
The mechanics that show up in escrow aren't tied to a specific airport's name. They're tied to noise contour math. Kings County's noise element prohibits new residential development outright inside a 70 CNEL or greater contour for any military airfield, airport, or helipad in the county. Inside the band between 60 and 70 CNEL, new residential construction is still allowed, but it comes with conditions: interior noise insulation to a minimum of 45 dB CNEL, a disclosure statement to prospective buyers that the parcel sits in an area that may see frequent aircraft noise events such as arrivals, departures, overflights, and engine run-ups, and an avigation easement recorded with the county on a newly created parcel or when a building permit is issued.
Read plainly, that toolkit isn't written to single out NAS Lemoore. It applies to whichever airport's noise contour actually reaches a given parcel. For most of Hanford, if that toolkit ever gets triggered, it's more likely to be triggered by the small general-aviation field a few minutes from downtown than by a Navy base 14 miles away.
An avigation easement, when one shows up on a title report, isn't a red flag about the home itself. It's simply a recorded right that allows aircraft, civilian or military, to fly over the property as part of normal airport operations. It doesn't affect ownership or use of the home beyond that.
The State-Level Disclosure Duty Underneath
Separate from anything Kings County requires locally, California law treats proximity to an airport as a material fact that must be disclosed in every residential resale. The state's Transfer Disclosure Statement calls out adjacency to an airport as a major neighborhood disturbance a seller has to address, and the standard is written to travel with the Natural Hazard Disclosure report rather than live only in the TDS itself.
The rule that decides when the "Notice of Airport in Vicinity" language gets triggered comes from legislation that established a fallback standard: if a formal airport influence area map exists, that map governs; if it doesn't, the law defaults to a two-statute-mile radius around any airport. That means a Hanford property doesn't need to sit inside a county overlay zone to see an airport disclosure. Being within two miles of Hanford Municipal Airport, or of NAS Lemoore for that matter, can be enough on its own under the state's default standard.
What to Actually Check Before You List or Write an Offer
- Ask the Kings County Community Development Agency which overlay zone, if any, covers the specific parcel. The agency's office sits at the Kings County Government Center on West Lacey Boulevard in Hanford, and zone boundaries are shown on the official county zoning map.
- Pull the preliminary title report early and look for a recorded avigation easement. If one exists, it's already part of the property's history and doesn't require new action, just accurate disclosure.
- Don't assume the absence of any mention of NAS Lemoore means no airport disclosure applies at all. The state's two-mile default and Hanford's own municipal airport can each trigger a disclosure independent of anything tied to the Navy base.
- If the transaction involves new construction or a fresh building permit near either airport, budget time for the interior noise insulation requirement if the parcel falls inside a 60 to 70 CNEL contour. That's a construction detail, not just paperwork.
A Short FAQ
Does this mean Hanford has a fighter jet noise problem? No. NAS Lemoore's noise contours are concentrated around Stratford and the rural county closer to the base itself, well outside most of Hanford's residential footprint.
Which part of Hanford sits closest to an airport overlay zone? The southeast edge of the city, nearest Hanford Municipal Airport, is where the city's own aviation compatibility zone applies.
Is an avigation easement something I should be worried about as a buyer? It's a recorded property right, not a defect. It simply confirms aircraft have the right to fly over the parcel as part of normal airport operations.
Does the disclosure requirement only apply to new homes? The avigation easement and noise insulation standards are tied to new parcels and building permits. The disclosure duty itself, both the county's and the state's, applies more broadly whenever a property sits within the relevant distance or contour, regardless of the home's age.
Who do I contact to confirm which zone applies to a specific address? The Kings County Community Development Agency, located at the Kings County Government Center, 1400 W. Lacey Blvd., Engineering Building 6, in Hanford, maintains the official zoning maps for both overlay zones.
