About Clay County
Clay County lies south of Duval County along the west bank of the St. Johns River in Northeast Florida, and the federal government counts it as part of the Jacksonville metropolitan area. Orange Park, a town with its own government, sits closest to Jacksonville, Green Cove Springs is the county seat, and Keystone Heights and Penney Farms lie in the interior. Most residents live outside the four municipalities, in unincorporated communities such as Fleming Island, Oakleaf Plantation, Middleburg and Lakeside.
The interior is lake and forest country. Lakes Brooklyn and Geneva lie beside Keystone Heights, Jennings State Forest covers part of the north near Orange Park, and Camp Blanding, a Florida National Guard training center, sits in Clay County about eleven miles east of Starke on State Road 16. That makes the county relevant to Guard members and other military buyers, though VA eligibility depends on service and not on where a home is.
Flood maps are the live local issue. FEMA released a preliminary flood insurance rate map for Clay County in May 2025, and a 90-day appeal period opened in August 2026, with a target of summer 2027 for the new map to take effect. Rivers in the county also reached major or record flood stages during Hurricane Irma in 2017. Before buying, look up the address on both the current and the preliminary map.

Housing in Clay County
Clay County is mostly detached single-family housing, according to the Census Bureau's 2020 to 2024 American Community Survey, and a notable share of the stock was built in the 2000s. The northern end around Orange Park, Fleming Island and Oakleaf Plantation works as suburban Jacksonville, while Green Cove Springs has a historic core by the river, Keystone Heights is a lake-region city, and the interior is more rural. Townhomes and small apartment buildings exist but are a modest part of the market.
Manufactured homes are a smaller but real part of the stock. Waterfront buyers should weigh two separate water questions: flood zones along the river and creeks, and lake levels in the Keystone Heights chain, where a 2021 St. Johns River Water Management District technical report found Lakes Brooklyn and Geneva not meeting the minimum levels the district proposed and called for a recovery strategy. Inside Orange Park, the town runs its own building division, so confirm whether the town or the county issues permits for an address.
Financing in Clay County
VA loans
VA home loan eligibility depends on a borrower's service, not on where the home is. Camp Blanding is in Clay County, and Guard members, other service members and veterans can ask a loan officer how their service counts. A Clay County home can be considered when the borrower is eligible and the home meets VA property rules.
USDA loans
USDA decides eligibility address by address with its property eligibility map. Clay County is largely suburban near the river, so many addresses there may not be eligible, while some interior addresses may be. Look up the exact parcel on the map before assuming anything, and ask a loan officer which income and property conditions the program applies.
Flood zones and flood insurance
FEMA's preliminary flood insurance rate map for Clay County was released in May 2025, and the City of Green Cove Springs reported an appeal period that opened in August 2026, with a target of summer 2027 for the new map to take effect. Comments and appeals go through local officials, and dates can change. Look up a property on both the current and the preliminary map in FEMA's Map Service Center before making an offer.
Homeowners insurance
Once a new flood map takes effect, federal law requires flood insurance for most mortgages on a building in a Special Flood Hazard Area, including a home newly mapped into one. FEMA says a Newly Mapped discount may be available for a policy bought or renewed within 12 months of the map update, and that most homeowners policies do not cover flood. Ask an insurance agent for quotes under the current and the proposed map before settling on a purchase.
Homestead exemption
Homestead applications go to the Clay County Property Appraiser, with a March 1 filing deadline for owners who held and lived in the home on January 1. Because Orange Park is a separate town government, ask the property appraiser or tax collector which taxing authorities appear on a specific parcel's bill, and review the first bill carefully, since a newly purchased home can show the seller's benefits for the first year.
Local homebuyer assistance
Florida Housing's listing says lenders and real estate agents may take part in Clay County's SHIP program if they follow the county's SHIP guidelines, which are posted on the county website. Ask the county's SHIP office for the current guidelines and funding status, since assistance depends on available funds and the household's eligibility and is not guaranteed.

Clay County: common questions
6 questions
Is Clay County's flood map changing?
Yes, per a City of Green Cove Springs notice from August 2026. FEMA released a preliminary map in May 2025, and a 90-day appeal period began in August 2026. The target date for the new map is summer 2027, and dates can change. Look up the address on both maps in FEMA's Map Service Center, and ask an insurance agent how a change could matter.
Which county is Camp Blanding in?
Camp Blanding uses a Starke mailing address. The Museum of Florida History places it in Clay County, about eleven miles east of Starke on State Road 16. VA home loan eligibility depends on a borrower's service, not on where the home is. A Clay County home can be considered if the borrower is eligible and the home meets VA property rules.
What happens if a Clay County home lands in a high-risk zone on the new flood map?
After the new map takes effect, a home newly placed in a high-risk zone falls under the federal rule that requires flood insurance for most mortgages. FEMA says a Newly Mapped discount may be available if a policy is bought or renewed within the first 12 months after the map update. Clay's map is still preliminary, so details can change. Ask an insurance agent for quotes under both maps.
Does the Town of Orange Park issue its own permits?
Orange Park is an incorporated town with its own government, and its website lists a Building Division and a code of ordinances. For an address inside the town, start with the town. For the unincorporated areas around Fleming Island, Oakleaf Plantation and Middleburg, start with Clay County. A parcel near a boundary should be checked with the property appraiser first.
Do lake levels matter for a home near Lake Geneva or Lake Brooklyn?
They can. A 2021 St. Johns River Water Management District technical report found both lakes, which sit beside Keystone Heights, not meeting the minimum levels the district proposed, and it called for a recovery strategy built around projects and added water supply options. Shorelines move with water levels, so ask for dated photos, inspect docks and shoreline in person, and ask the district for current information before relying on a lake view.
Can any lender or real estate agent work with Clay County's SHIP program?
Florida Housing's listing says lenders and real estate agents may take part if they follow the county's SHIP guidelines, which are posted on the county website. A buyer should confirm that the professionals involved are comfortable with those guidelines before relying on the program. Assistance is not guaranteed and depends on funds, so contact the county's SHIP office for the current guidelines.
