What format are MEP plans delivered in?

Your plans are delivered as PDF files formatted for 24" x 36" printing — the standard large-format sheet size California building departments require for permit submittal. The files are ready for both electronic and physical submission, with no reformatting needed on your end.

Why 24" x 36" matters

Most jurisdictions specify a large-format sheet (commonly 24" x 36", sometimes 30" x 42") so reviewers can read every callout, schedule, and note at the proper scale. Delivering at this size means your MEP sheets line up cleanly with the rest of your permit set and won't be bounced for a sheet-size or scale mismatch — a surprisingly common reason packages get returned before substantive review even begins.

Electronic and physical submittal

• Electronic plan review — The PDFs are compatible with California's electronic submittal portals, including systems like ePlanLA, eTRACKiT, and similar platforms used by cities and counties statewide. They upload without conversion.
• Physical submittal — When a counter still wants paper, the same files print at any FedEx Office or large-format print shop without modification.

What's inside each sheet

Every sheet arrives fully formatted and ready to drop into your application:

• Proper sheet labeling (M-1, M-2, E-1, E-2, P-1, P-2) and a sheet index on the cover
• A title block with project address, scale, and code references
• Vector-quality linework that stays crisp when printed at full size
• Schedules, calculations, and notes laid out the way reviewers expect to read them

Revisions and resubmittals

If the city issues corrections, we update the source files and re-deliver clean, resubmittal-ready PDFs — your two included revisions and city corrections are handled at no extra charge. Because the files are vector PDFs rather than scanned images, every revision stays sharp and legible, which keeps the reviewer focused on the design instead of struggling to read it.

How to assemble your full submittal

Your MEP PDFs are designed to combine cleanly with the rest of your permit package. A typical California ADU submittal includes:

• Architectural sheets (A-series)
• Structural sheets (S-series), if your project requires them
• Your MEP sheets (M, E, and P series)
• The Title 24 energy report (CF1R), where applicable

Because every set is delivered at the same standard sheet size, you or your designer can merge them into a single ordered PDF for portal upload, or print them together as one coordinated set for a paper counter — without any sheet resizing or scale conflicts.

Printing and sharing

The PDFs open in any standard viewer, so you can share them with your contractor, lender, or HOA for review before submitting. For construction, the same files print at full 24" x 36" size so your installers can read the schedules and circuit layouts in the field. There is no proprietary software required and no special license to view, mark up, or print your own plans.

The goal of the delivery format is zero friction at the counter: the right size, the right portal compatibility, and the right labeling so your set is accepted on the first upload.
