Key ADU Restrictions in Orange Park
These are the rules that most often catch homeowners by surprise. Read them carefully before engaging an architect.
- Most of what's called 'Orange Park' is unincorporated Clay County — confirm jurisdiction before contacting the Town of Orange Park building department
- HOA communities are common throughout Clay County's planned neighborhoods (Oakleaf Plantation, Fleming Island) — check CC&Rs before planning
- Clay County has a mixed permit workload — review times can vary; plan for potential 6–10 week review periods
Common Mistakes to Avoid in Orange Park
- NAS Jacksonville BAH (Basic Allowance for Housing) drives a reliable LTR market for E-4 through O-3 ranks — ADUs priced at $950–$1,400/month fill quickly with military tenants
- Fleming Island (south of Orange Park in Clay County) is a more affluent sub-market with higher rents and newer construction — worth considering for a premium ADU build
- Orange Park area has mostly flat terrain and shallow water tables — drainage planning is important for ADU foundations, especially in older neighborhoods

Orange Park ADU — Frequently Asked Questions
These are the questions we hear most often from Orange Park homeowners. If yours isn't here, our ADU Zoning Experts can answer it directly.
Is Orange Park's rental market strong enough to justify an ADU build?
Orange Park offers reliable, stable rental income rather than high yields. The military tenant base from NAS Jacksonville (15,000+ personnel) creates structural demand for quality rental housing in the $950–$1,400/month range. Orange Park Medical Center and the growth of the Clay County school system also drive healthcare and teacher demand. If your goal is low-risk, low-vacancy LTR income, Orange Park delivers. If you're targeting STR yields, this is not the market.
