Stop dedicating in-house staff to solar permit documentation. Outsource your solar PV permit drawings to Permit Design — and get complete, NEC 2017-compliant plan sets delivered in 24–48 hours for any Wisconsin AHJ.
Producing solar permit drawings and plan sets in-house creates fixed overhead, staffing bottlenecks, and code compliance risk. Here's why 150+ Wisconsin solar companies outsource to Permit Design.
Wisconsin is the #28 residential solar market nationally — and average AHJ review times of 11 business days at Milwaukee Building Inspections mean permit documentation quality directly impacts your project schedule. The Focus on Energy Solar Incentive is actively pulling new homeowners into the market, increasing installer workloads. Most growing Wisconsin 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 Wisconsin team delivers complete plan sets in 24–48 hours — regardless of your project volume. Same-day rush available.
We know what Milwaukee Building Inspections, Dane County Permits, and every Wisconsin 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 Wisconsin permit drawings to Permit Design scales perfectly with your project volume.
Staying current with NEC 2017 & Wisconsin Uniform Dwelling Code and local Wisconsin amendments is a full-time job. Our team maintains continuous knowledge of every Wisconsin code update — you never have to worry about using the wrong edition.
Wisconsin Electric Power (WEC) and Wisconsin Public Service (WEC) each have specific interconnection documentation requirements. Our Wisconsin plan sets cover both — no separate utility package, no extra steps.
If your Wisconsin 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.
Wisconsin is the #28 solar market nationally for residential solar installations. With approximately 142 MW of residential solar installed in 2024 and average AHJ review times of 11 business days at Milwaukee Building Inspections, getting your permit documentation right on the first submission directly impacts project profitability. The Focus on Energy Solar Incentive is the primary state-level financial incentive driving installer activity in Wisconsin.
For Wisconsin 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 11 days is the average at Milwaukee Building Inspections. Jurisdictions that receive complete, AHJ-ready plan sets on first submission consistently process permits faster than the average. An incomplete first submission at Milwaukee Building Inspections can add another 11 days or more to your project timeline, pushing installation and PTO out by weeks.
Our Wisconsin solar permit drawing service is purpose-built for this reality. Every plan set we produce for Wisconsin projects is prepared to Milwaukee Building Inspections's specific checklist — not a generic national template. That means our Wisconsin clients average first-pass approval rates well above the statewide average, and spend far less time chasing corrections, resubmitting paperwork, or explaining documentation to Wisconsin reviewers.

Wisconsin uses NEC 2017 under the Wisconsin Uniform Dwelling Code. We Energies, WPS, Alliant Energy, and MGE each have specific solar permit drawing requirements. Wisconsin's cold climate means snow load structural documentation is often required in solar permit plan sets.
