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 New York

New York runs a statewide Uniform Code through the Department of State everywhere except New York City, which enforces its own Building Code and its own Zoning Resolution.

City of Yes changed what New York projects are possible in 2026. The citywide zoning reform known as City of Yes for Housing Opportunity reshaped what can get built across New York, and 2026 is the first full year where the effects show up in a real construction pipeline rather than a policy debate. The reform expanded office-to-residential conversion eligibility from buildings constructed before 1961 to buildings constructed before 1991, added flexibility for mixed-use development, and relaxed rules governing light, air, and unit layout that had made many conversions mathematically impossible under the old code. The first full year under City of Yes produced roughly 23 percent more new homes citywide.

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.
