Common Questions
Building a Custom Home in Jacksonville?
Everything Northeast Florida homebuilders need to know before breaking ground.
How much does it cost to build a custom home in Jacksonville?
BuilderK's shared calculator uses Central Florida base planning rates of Standard ($160 to $180/sqft), Midrange ($180 to $220/sqft), and Luxury ($220 to $280+/sqft), last updated July 18, 2026. It returns one combined planning range from the selections entered. Land, financing, government permit and impact fees, utilities, unusual site work, and the calculator's other listed exclusions are not included. Duval or St. Johns County permitting, coastal, flood zone, and site requirements can materially change the range. After we review the plan, scope and site, we send a formal proposal. Use the planning calculator for an early range.
How long does it take to build a custom home in Jacksonville?
A typical custom home in Jacksonville takes 6 to 10 months from permit approval to move in. The full timeline including design, financing, and permitting is usually 9 to 14 months from your first consultation. Builds in beach communities or flood zones may require additional permitting time. BuilderK provides regular progress updates throughout the entire build.
Can I build on my own lot in Duval County or St. Johns County?
Yes. If you own a lot in Duval County, St. Johns County, or Clay County, BuilderK can build your custom home on it. Jacksonville's large lot sizes are ideal for custom construction. Your lot's appraised equity may reduce or replace cash required by a lender, depending on the appraisal, total project cost, borrower qualifications, and loan program. Learn about financing
What permits are required to build a home in Jacksonville?
All new home construction in Jacksonville requires building permits from Duval County or the City of Jacksonville. This includes site plans, engineering, and inspections. Coastal properties near the beaches also need flood zone compliance and wind load certifications. BuilderK handles the entire permitting process so you don't have to navigate any of it yourself.
What credit score do I need for a construction loan in Jacksonville?
Construction loan requirements vary by lender and program. Many programs look for a credit score around 680, while others accept lower scores or are based on assets and weigh the project more than the borrower's credit. BuilderK connects you with lenders who specialize in construction to permanent loans, and we handle all the builder paperwork to streamline your approval. Check your eligibility
