Modular ADU vs Stick-Built ADU in Jacksonville, FL | Which Is Better?

Which Works Best for Larger Lots and Faster Growth?

Jacksonville’s size and growth create a different ADU equation than other Florida cities.

Lot Size & Access in Jacksonville

Many Jacksonville properties offer:

• Easier backyard access

• Larger setbacks

• Fewer space constraints

This gives both construction methods room to work — but timelines still matter.

Construction Speed & ROI

Jacksonville homeowners often build ADUs for:

• Rental income

• Multigenerational housing

Modular ADUs

• Faster completion

• Quicker rental readiness

• More predictable budgets

Stick-built ADUs

• Greater design freedom

• Longer timelines

• More exposure to cost overruns

Weather & Scheduling

Even with more space, Jacksonville still experiences:

• Rain delays

• Heat-related slowdowns

• Trade scheduling conflicts

Modular construction minimizes these issues.

Jacksonville Verdict

For homeowners focused on speed, rental income, and cost certainty, modular ADUs are often the better choice. Stick-built works well for custom designs where time is less critical.
