"Do I need a permit for a deck" doesn't have one answer in this market, it depends on which of nine towns and two counties your address falls in, and the answer changes the fee, the footing spec, and who you actually call. Here's the real breakdown by jurisdiction, sourced directly from each building department, not a generic national answer that happens to be wrong for your address.
Springfield has adopted the 2018 International Building Code and International Model Codes. Permits are required for essentially all building-related construction inside city limits. Unlike a flat fee, Springfield calculates permit cost by a size-based formula (square footage run through a construction-factor calculation), not a single number, so the fee scales with your deck's footprint. Exemption thresholds for small or low decks vary by jurisdiction, so don't assume yours is exempt without checking. Contact Building Development Services directly at (417) 864-1585 for your specific project's fee and to confirm whether a permit is required, the office is at 840 Boonville Ave., 1st Floor.
It would be simpler to say "Republic, Battlefield, Willard, Rogersville, and Strafford all follow Greene County's rules," and that was our first assumption too, until we checked each city directly and found it's wrong. Every one of these five towns runs its own building/permitting department, separate from Greene County, the same way Nixa and Ozark do in Christian County. Greene County's own detailed deck requirements document (footings minimum 16" diameter, 8" thick, 18" deep from finished grade; guardrails above 30" floor height; engineered design required past 14 feet of depth) is real and useful as a reference standard, but it's Greene County's rule for its own unincorporated area, not automatically the rule inside any of these five city limits.
Republic publishes its own full deck construction guide, and it differs from Greene County's in real ways: footings run 18" round or 16" square with depth tied to local frost depth rather than a flat 18", joist spans are calculated slightly differently, and a required site plan carries a 6-foot minimum side-yard setback. One rule worth knowing before you buy anything: a pre-fabricated composite or plastic guardrail system from a home center requires a full plan submission unless it's specifically listed by an accredited testing agency, not something most homeowners expect when picking up a rail kit.

Willard runs its own Planning and Development Department (City Hall, 224 W. Jackson St., (417) 742-5302) and has adopted the 2018 International Building Code and 2017 NEC, a newer code cycle than Greene County's own 2012 adoption just down the road.
Battlefield, Rogersville, and Strafford each run their own permit process as well (Battlefield's own department; Rogersville City Hall at (417) 753-2884; Strafford's Building Development Services at [email protected] or (417) 736-2154). Footing and guardrail specifics are set by each city individually, confirm those directly with the relevant department before finalizing a design rather than assuming a neighboring jurisdiction's numbers apply.
This is where a lot of homeowners get tripped up: these four towns are in Christian County, not Greene County, and the rules aren't identical.
Assuming your deck follows "the Springfield rule" when you're actually in Nixa, or assuming Greene County's footing spec applies inside Republic city limits when Republic runs its own separate standard, is exactly the kind of mistake that gets a project stopped mid-build for a failed inspection. A local builder who already knows which jurisdiction your address falls in, and pulls the correct permit the first time, saves real time versus finding out the hard way.
At minimum, you risk a stop-work order and having to open up finished work for inspection after the fact. It can also become a real problem at resale, an unpermitted structure is something a home inspector or buyer's agent will flag. It's not worth the shortcut.
It varies by jurisdiction, across nine different towns there's no single answer. Ask directly when you apply, and build the wait into your project timeline rather than assuming construction can start immediately.
The permit fee itself goes to the city or county regardless of who applies for it. Many builders include pulling the permit and scheduling inspections as part of their quoted price, worth confirming that's included before you sign anything.
