Step 1: Preparation

Find zoning information for the property on the city’s assessor site. You will need that information to determine what will be needed for the building permit.

• City of Madison Assessor's Property Lookup
• Property Class: classification of building; commercial or residential
• Zoning:
• CC, CC-T, SR-V1, TR-C1.... - commercial or residential category
• PD – Planned Development
• HIS – Historic District
• UDC – Urban Design Commission
• In case of commercial building, find out the volume in ft³ (larger or smaller than 50,000 ft³
• In case of residential building, determine if it has more than two family dwelling units.
• In case of PD, HIS or UDC you will need to provide additional documents (see step 3) and it might require more time. Please consider that in your construction schedule.

Step 2: Produce documents for electrical,
plumbing, and heating permits

Electrical, plumbing, and heating permits require the typical documentation to prove that all codes and requirements are met. This should not be a problem for a contractor who is in the business of installing solar systems. Documents needed include but are not limited to:

• Plumbing (for domestic hot water): A catalog cut sheet of the device. Proof that the transfer fluid is either non-toxic or the device has a double walled heat exchanger.

• Electrical: A catalog cut sheet of the electrical photovoltaic device that shows it is UL listed.
• Heating: Information that shows compliance with MGO 30.05. All materials that are used in the system must be listed.
• Proof that applicant holds all necessary licenses.

Step 3: Produce documents for building permit

You will need to pay applicable fees to obtain all the permits.  Staff can tell you the exact amount for your specific project at time of application.

Step 4: Application

In case your property is in a PD, Urban Design district, or historic district, contact the appropriate staff (s. step 3) to make special arrangements prior to your application. These staff might not be available if you show up unannounced and the process might require more days.

In cases where the PD, Urban Design district, or historic issues are resolved or not applicable, show up at the permit office during business hours with all your documents and be prepared to pay the fees. If all documents are complete and acceptable, you will receive your permit right away.

You may call the Zoning and Building Inspection Staff prior visiting the zoning counter to double-check if you are unsure about any of the requirements.

Step 5: Approval

Once approved you will receive the permits, which need to be displayed at the construction site. The permit will include contact information for the inspector(s) who can answer more questions. You will need to schedule for inspections during and after construction. Work needs to be inspected before you may proceed with the next step. After completion there will be a final inspection. You are responsible to arrange those inspections with the inspector.
