Permit Drawings vs Construction Drawings: What Is the Difference?
They overlap, and on small projects they are often the same set. But they are produced for two different readers, and knowing which you are buying prevents an expensive misunderstanding.
Permit drawings are for the plan checker
Their job is to prove compliance. They show the reviewer that the design meets the code: setbacks, egress, occupancy, structural adequacy, energy compliance. They contain what the jurisdiction needs to approve the work, and not much more.
Construction drawings are for the builder
Their job is to get it built correctly. They carry more dimensional detail, assemblies, finishes, schedules and coordination between trades. A builder can price and build from them without constant clarification.
Where people get caught out
On a small residential job, one set usually serves both purposes. On larger work they diverge, and a permit-only set handed to a builder produces a stream of questions, change orders and guesswork on site. If you intend to build from the drawings, say so before the scope is agreed, because it changes the level of detail and the price.
What we deliver
Our standard sets are permit sets: complete, sealed, and prepared for submission to your jurisdiction. Where you need construction-level detail as well, tell us at the quote stage and we scope it in rather than discovering it later.
Frequently asked questions
Can I build from permit drawings?
On simple residential work, usually yes. On anything with trade coordination, you will want construction-level detail or your builder will be making decisions that should have been yours.
Are as-built drawings the same thing?
No. As-builts record what exists today, usually measured from the building. They are often the starting point for a permit set on a renovation, not the output.
Which do I need for a contractor to quote?
Contractors can price from a permit set but their number will carry more contingency, because anything undrawn is a risk they price for. More detail generally means tighter pricing.
