Permit-Ready vs Construction Documents: What's Different?

Permit-ready drawings prove code compliance for plan review; construction documents add the full dimensions, details, and coordination needed to price and build the work. Complex projects need both phases; simple ones can combine them.

The concise answer

Permit-ready drawings prove code compliance for plan review; construction documents add the full dimensions, details, and coordination needed to price and build the work. Complex projects need both phases; simple ones can combine them. The permit set's audience is the plan reviewer: it demonstrates structural adequacy through calculations, MEP compliance through layouts and schedules, energy compliance through forms and modeling, and life safety through egress and fire protection design. The construction set's audience is the contractor and the field: enlarged details, exact dimensions, coordination between disciplines, specifications, and the thousand small decisions that turn a compliant design into a buildable one.

What lives in each set

Permit set essentials: code analysis sheets, structural plans with calculations, MEP plans with equipment schedules and load calculations, energy compliance documentation, plumbing fixture counts, egress plans, and accessibility compliance. What's often deferred to construction documents: detailed sections and enlarged plans, full specifications (permit sets may carry outline specs), coordination details between trades, final equipment selections with cut sheets, and construction administration details like phasing and temporary provisions. The specifications deserve emphasis. A permit set might reference performance criteria; construction documents need the prescriptive specs telling the contractor exactly what to buy and install. Owners who bid from spec-light permit sets discover the difference when the submittals arrive.

How to use the distinction strategically

The two-phase approach is a schedule tool when used deliberately:

  • Fast-track: submit the permit set early on long-lead jurisdictions while detailing continues
  • Phased permits: foundations and structure permitted first, interiors later — each phase needs its own permit-ready scope
  • Bid timing: don't bid from the permit set unless it's genuinely construction-grade — under-bidding helps no one
  • Revision control: every change after permit issuance needs a revision — track what changed and why
  • Contractor input: issue construction documents for pre-construction review so the builder's feedback improves the details
  • As-builts: the construction set becomes the baseline for as-built documentation — keep it current through construction

What else do project teams ask?

Can I build from the permit set?
On simple projects, often yes — a straightforward tenant improvement's permit set may be complete enough to build from. On complex projects, no: the permit set typically lacks the detailing, dimensions, and systems coordination the contractor needs. Your engineer should tell you explicitly which one you're getting.
Why do engineers issue a permit set before construction documents are done?
To start the permit clock early. Plan review takes weeks to months, so submitting a code-complete permit set while detailing continues in parallel can save significant schedule. The risk is that review comments or detailing changes force permit revisions — which is why the strategy needs to be deliberate, not accidental.
What is a 'permit set' versus a 'bid set'?
A bid set (or pricing set) is issued to contractors for bidding and falls between the two: more developed than a bare permit set, but not yet the final construction documents. It needs enough detail for accurate pricing. Bidding from an under-detailed permit set is a classic source of low bids followed by expensive change orders.
What should I send for an initial review?
Send the project address, plain-language scope, current drawings at whatever stage they exist, schedule and permit goals, and the authority or code information already available. The responsible engineer will identify gaps.
