What documents a permit application needs
Permit applications are refused at intake far more often than they are refused at review, and nearly always for the same reason: the package is incomplete. Intake staff are not assessing your project, they are checking a list. Meeting that list is entirely within your control.
Required on essentially every application
- The completed application form for the correct permit type — using the current version, downloaded the day you submit.
- Property address and, more usefully, the parcel or assessor number.
- A written scope of work describing exactly what will be done. Vague scopes are the most common intake rejection.
- Declared valuation including labour and materials.
- Owner authorisation, or an owner-builder declaration if you are doing the work yourself.
- Contractor licence details, liability insurance and workers compensation certificates.
What each scope adds
- Structural work — drawings showing existing and proposed conditions, details for any changed load path, and an engineer or architect stamp where the jurisdiction or the scope requires one.
- New footprint — a site plan with property lines, existing structures, the proposed work and setback dimensions, plus lot coverage calculations.
- Ground disturbance — grading, drainage or erosion control plans.
- New or altered conditioned space — energy code compliance forms for the climate zone, with assembly R-values and window U-factors.
- Trade work — electrical load calculations and panel schedules, plumbing fixture counts and drain-waste-vent layouts, mechanical equipment specifications with combustion air and venting.
- Flood zone — elevation certificate, and a substantial improvement calculation comparing project cost against market value.
- Historic district — certificate of appropriateness or design review approval, which is usually a separate approval obtained before the building permit.
- Commercial — sealed drawings across architectural, structural, mechanical, electrical and plumbing, accessibility documentation, and fire and life-safety plans.
Drawings that get accepted
Drawings do not have to be beautiful, but they do have to be legible, dimensioned and to a stated scale. Show what exists and what is proposed as separate views rather than one annotated hybrid — reviewers need to see the difference. Label rooms by use, mark egress windows and doors, and dimension anything a setback or a clearance depends on.
Use the jurisdiction's own forms
Application forms are revised regularly and offices reject superseded versions. Download the form on the day you submit rather than reusing one from a previous project, and never use a form found on a third-party site. This is why we link to each jurisdiction's forms page rather than hosting copies of the forms ourselves — a cached form is a liability, not a convenience.
If you are unsure whether your package is complete, ask for a pre-application review. Many offices offer one, most will answer a specific question at the counter or by email, and fifteen minutes there routinely saves a fortnight of resubmission.
Questions people ask about this
Do I need an architect or engineer to submit drawings?
It depends on the scope and the jurisdiction. Structural changes, commercial work and anything above a size or complexity threshold generally require a stamp. Straightforward residential work often does not. Ask the office before paying for drawings you may not need — or worse, submitting unstamped ones that will be rejected.
Can I submit hand-drawn plans?
In many jurisdictions yes, for simple residential work, provided they are legible, dimensioned and to scale. Ask first, because some offices require CAD or PDF at a specific size.
What is a scope of work and why does it matter so much?
A plain description of exactly what will be done. It determines which permit type applies, which reviews are triggered and what the inspector will check. A vague scope produces a wrong permit type, which surfaces at inspection when it is expensive to fix.
How long are approved plans valid?
Approved plans are tied to the permit, so they lapse when the permit does. If a permit expires and cannot be reinstated, the replacement is reviewed against the current code edition, which can mean redrawing.
