Permit Packages
Complete jurisdiction-compliant submission sets built against the reviewer's own checklist.
Permit Packages
Permit rejection is rarely about engineering. It is about a missing label detail, a pathway measured to the wrong edge, a structural calculation that does not name the applicable code edition, or a sheet the authority expects in a particular position in the set. Each rejection costs a week.
We build permit packages jurisdiction by jurisdiction. For every authority you submit to we hold a checklist covering adopted code editions, fire setback and access pathway rules, rapid shutdown and labelling requirements, structural attachment and loading documentation, sheet order and any local quirks the review office actually enforces. Where you have submission history with that authority, their past comments go into the checklist too.
Sets are prepared to be signed and sealed by your licensed professional. We do not stamp drawings and we say so clearly — what we do is make sure that when your engineer reads the set, there is nothing left for them to fix.
