Stop dedicating in-house staff to solar permit documentation. Outsource your professional solar permit plan sets to Permit Design — and get complete, NEC 2020-compliant plan sets delivered in 24–48 hours for any Missouri AHJ.
Producing solar permit drawings and plan sets in-house creates fixed overhead, staffing bottlenecks, and code compliance risk. Here's why 150+ Missouri solar companies outsource to Permit Design.
Missouri is the #29 residential solar market nationally — and average AHJ review times of 10 business days at Kansas City Building Dept mean permit documentation quality directly impacts your project schedule. The Ameren MO Net Metering Program is actively pulling new homeowners into the market, increasing installer workloads. Most growing Missouri solar companies find that outsourcing permit drawings to Permit Design is the fastest path to higher volume without adding fixed in-house drafting overhead.
In-house solar permit documentation often takes 3–5 days. Our Missouri team delivers complete plan sets in 24–48 hours — regardless of your project volume. Same-day rush available.
We know what Kansas City Building Dept, St. Louis Building Division, and every Missouri AHJ expect. Our plan sets don't generate correction requests — because we build them to each AHJ's specific checklist from the start.
Pay only for the plan sets you need. No salary overhead, no benefits, no software licensing. Outsourcing Missouri permit drawings to Permit Design scales perfectly with your project volume.
Staying current with NEC 2020 & Missouri Building Codes and local Missouri amendments is a full-time job. Our team maintains continuous knowledge of every Missouri code update — you never have to worry about using the wrong edition.
Ameren Missouri (Union Electric) and Kansas City Power & Light (Evergy) each have specific interconnection documentation requirements. Our Missouri plan sets cover both — no separate utility package, no extra steps.
If your Missouri AHJ requests changes to any sheet in the plan set, we revise at no charge — same-day for most requests. Your permit approval is our shared goal.
Missouri is the #29 solar market nationally for residential solar installations. With approximately 118 MW of residential solar installed in 2024 and average AHJ review times of 10 business days at Kansas City Building Dept, getting your permit documentation right on the first submission directly impacts project profitability. The Ameren MO Net Metering Program is the primary state-level financial incentive driving installer activity in Missouri.
For Missouri solar installers, permit turnaround time is a direct cost. Every business day a permit sits in AHJ review is a day the project cannot be installed — and 10 days is the average at Kansas City Building Dept. Jurisdictions that receive complete, AHJ-ready plan sets on first submission consistently process permits faster than the average. An incomplete first submission at Kansas City Building Dept can add another 10 days or more to your project timeline, pushing installation and PTO out by weeks.
Our Missouri solar permit drawing service is purpose-built for this reality. Every plan set we produce for Missouri projects is prepared to Kansas City Building Dept's specific checklist — not a generic national template. That means our Missouri clients average first-pass approval rates well above the statewide average, and spend far less time chasing corrections, resubmitting paperwork, or explaining documentation to Missouri reviewers.
