Adding a second story is one of the most common ways Madison homeowners gain space without giving up the yard. The project starts with drawings: the city needs to see the existing house, the new floor and how the two connect before it issues a permit.

What does the drawing set include?

A second story plan set starts with the house as it stands today: we draft existing floor plans and elevations from your measurements and photos, or from old plans if you have them. Then we draft the proposed second floor, the new stair and how it lands on the first floor, the new roof and updated elevations on all four sides. Building sections show floor-to-floor heights and how the new floor sits on the existing walls. Your structural engineer uses the same files to size beams and footings.

Permits and review in Madison

Wisconsin enforces statewide codes through the Department of Safety and Professional Services, and its uniform dwelling code applies to one and two family homes everywhere in the state, which is unusual.

Who reviews a Madison project, and how the isthmus geography shapes what gets approved. Madison development review runs through the city's Plan Commission and Urban Design Commission, with the latter carrying particular weight for downtown and isthmus-area projects given the genuine physical constraints of building on a narrow strip of land between two lakes. Projects along the Pennsylvania Avenue corridor or near the State Street Campus Garage site face review calibrated to this specific geography, distinct from the more open suburban zoning context common in Madison's outlying neighborhoods. The city's Department of Planning and Community and Economic Development coordinates the broader Downtown Area Plan process, expected to complete by spring 2027, meaning some review standards for larger downtown proposals remain genuinely in flux.

Your local building department sets the final submittal checklist. We draft to the sheet content reviewers ask for and revise if the reviewer issues comments on the drawings we produced.

How does the drafting work?

1. You send photos, measurements or old plans of the house and your wish list.
2. We draft existing conditions and confirm them with you.
3. We draft the proposed second floor, stair, roof and elevations.
4. You and your engineer review; we apply revisions.
5. Final DWG and PDF permit set.

What do you need to send us?

• Photos of every side of the house and the interior rooms
• Measurements or old plans if available
• Wish list: bedrooms, baths, stair location

If you are not sure what you have is enough, send it anyway. We review it the same business day and tell you exactly what is missing, if anything.

How fast is it and what does it cost?

Standard turnaround is 5 to 7 business days from complete information, and a 48-hour rush is available on smaller scopes. Every project gets a fixed quote before drafting starts, based on the number of sheets, the size of the building and how much existing conditions work is needed. There are no hourly surprises: revisions on the drawings we produced are included until the set is ready to submit.

How are the files delivered?

You receive native DWG files on named layers (walls, doors and windows, dimensions, text, existing and new work kept apart), a plotted PDF set at the correct sheet size and scale, and a short sheet index. Your engineer, contractor or permit expediter can open the files without cleanup, add their own sheets and keep working on the same base drawings.
