Short answer: schedule only when the work is ready, never cover work before its rough-in is approved, keep the permit card and approved plans on site, and make sure the inspector can get in. Ask your building department for its inspection order before work starts; Portland even offers a free pre-construction consultation with the permit.
Passing inspection is not about charming the inspector. It is about having the right work visible (or finished), the permit card posted, approved plans on site, and access that does not waste a truck roll. Failing is expensive in calendar time—and sometimes in reinspection fees.
Everything here happens before the inspector arrives: knowing the order your city expects, getting rough-in and final building permit inspections ready, and making the visit easy. Frisco, Texas and Portland, Oregon publish their checklists in plain language, so they serve as the examples. Your own AHJ’s order and codes win.

Know your sequence before you schedule
Residential projects usually follow a rough-before-cover logic: underground/slab work, then rough plumbing/electrical/mechanical and framing, then insulation/energy, then finishes, then trade finals and building final. Frisco, Texas’s Residential Inspection Checklist & Guide (Form 4032, revised February 2026) publishes an ordered list for new residential construction that includes temporary power, plumbing rough-in, slab, flatwork, plumbing top-out and mechanical rough, framing, insulation, drywall, brick ties, electrical final, plumbing/mechanical final, utility inspection, and certificate of occupancy / building final.
Your remodel will not need every Frisco new-construction step—but the principle holds: do not cover work that still needs eyes. Portland’s electrical pages say the same for rough-in: no insulation, receptacles, or switches until rough is approved.
Book the free consultation first (Portland’s example)
Portland offers something many homeowners never use: a pre-construction consultation inspection. It is included with the approved permit at no extra cost, and the city recommends scheduling it before any work starts. The inspector goes over your approved plans and tells you which inspections you will need. You request it by trade using code 295 for structural, 155 for electrical, 397 for plumbing, or 650 for mechanical. The inspector calls between 7:30 and 8:30 a.m. that day and decides whether the question can be settled by phone or needs a site visit.
Two things to know about it. A consultation does not count as an approved inspection, so every required inspection still has to be scheduled and passed. And Portland lays out the order it wants for interior remodels and conversions: electrical rough-in (105), plumbing rough-in/top-out (310), mechanical rough-in (620), shear wall/framing (260/270) if structure changes, insulation (280), trade finals (199/399/699), then final building/final permit (299/999). All rough trade inspections must be approved before the 270 framing inspection, and every permit needs the 999 Final Permit inspection to close. Even if your city uses different codes, asking for this kind of list up front saves a wasted trip.
Portland's interior remodel inspection order
| Step | Inspection | Portland code |
|---|---|---|
| 1 | Electrical rough-in | 105 |
| 2 | Plumbing rough-in / top-out | 310 |
| 3 | Mechanical rough-in | 620 |
| 4 | Shear wall / framing (if structure changes) | 260 / 270 |
| 5 | Insulation | 280 |
| 6 | Trade finals (electrical, plumbing, mechanical) | 199 / 399 / 699 |
| 7 | Final building / final permit | 299 / 999 |

Rough-in prep checklist
- Permit card posted and visible; approved plans on site
- Address visible from the street
- Safe access path; dogs secured; gate codes shared if needed
- Work exposed: open walls/ceilings as required for the trade
- Nail plates, straps, fireblocking, and supports installed where required
- Tests ready (e.g., plumbing pressure/stack tests per local rules)
- Prior correction items fully addressed
Schedule only when the work is actually ready. “Maybe they’ll pass the parts that are done” is how you burn a reinspection fee.
Final inspection prep checklist
- All prior rough approvals documented
- Life-safety devices installed: smoke/CO alarms, handrails, guards
- Egress windows operable; tempered glazing where required
- Fixtures set; equipment labeled; panels have clear working space
- Site conditions met (address, drainage, required erosion controls on larger jobs)
- Energy features complete if your AHJ inspects them at final
- Permit history clean enough to close—no orphan trade cards
For electrical specifically, Portland requires a final (#199) with covers on, circuits labeled, and equipment energized; without it the permit stays “under inspection,” and more than 180 days between inspections can expire the card. Enter your last passed inspection date in our permit expiration calculator to see when the card could lapse.

If the inspector writes you up
Most fails come down to the same few causes: no access, unfinished work, a code item, or missing papers. The checklists above are meant to head those off. If one gets through anyway, the steps after a fail (sorting the items, reinspection fees, and keeping the permit alive) are in the failed final inspection playbook. If you think the call was wrong, see how to appeal a building inspector’s decision.
Trade-specific reminders
- Electrical — rough before cover; service/panel clearances; final labeling (electrical guide)
- Mechanical — do not operate gas appliances before approval if forbidden; Manual J docs on site when required (HVAC guide)
- Roof — decking checks before covering when sheathing is in scope (roof guide)
- Solar — labeling, grounding, rapid shutdown ready before final (solar guide)
- ADU / garage — egress, smoke/CO, fire separation visible for finals (ADU guide)
Day-of logistics that save the visit
- Confirm the inspection window and type code (many IVR systems need a three-digit code).
- Put the permit packet on the kitchen counter or job box—do not make the inspector hunt.
- Turn on lights / temporary power as needed for visibility.
- Have the responsible person reachable by phone.
- If you must cancel, cancel early—Frisco notes same-day cancellations go through the assigned inspector; utilities may bill if not canceled with enough notice.
After a pass: close the loop
A passed final that never gets recorded as closed is still a headache. Check the portal status, download the result, and keep PDFs with your house records. If you are selling soon, buyers and lenders will look for closed permits—see also expired/open permit cleanup.
Remodel vs new construction sequences
Frisco’s published residential sequence is written for new houses, but remodelers should still map an equivalent path: demolition/site safety, rough trades, framing corrections, insulation, drywall, and finals. Partial permits (electrical-only, mechanical-only) still need their own finals—do not assume a building final closes orphan trade cards.
If you are coordinating a roof, solar, and panel upgrade in one season, sequence inspections so you are not asking for a roof final while the service mast is mid-upgrade. Cross-read the roof, solar, and electrical guides when projects overlap.
Documentation to keep after every visit
Save every result the day it posts, passed ones included. A photo of the open wall next to the approved rough-in result is what proves, years later, that the wiring was seen before drywall. Keep those files with the signed contract.
On a complex job, plan for at least one callback. Good records make that callback short.
Job-site courtesy that inspectors notice
Clear a path, leash pets, silence loud music, and have a knowledgeable adult present. Inspectors are not your design consultants, but they will answer clarifying questions about the written correction list. Arguing code from memory rarely helps; asking “which section should I study for this item?” often does. A tidy site signals that the rest of the work got the same care.
Five habits that pass inspections
- Learn your AHJ’s sequence; never cover before rough approval.
- Schedule only when ready—fails cost time and sometimes fees.
- Post the permit, keep plans on site, and guarantee access.
- Ask for the inspection list (or a consultation) before work starts.
- Verify the portal shows closed after final.

FAQ
What is a rough-in inspection?
It's the inspection of plumbing, electrical, mechanical, or framing work while walls and ceilings are still open. Portland's electrical pages say no insulation, receptacles, or switches until rough-in is approved (Portland.gov).
Is Portland's pre-construction consultation an inspection?
No. It's included with the approved permit at no extra cost, but it doesn't count as an approved inspection, so every required inspection still has to be scheduled and passed (Portland.gov).
Can a permit expire between inspections?
Yes. Portland says more than 180 days between inspections can expire the permit, and an electrical permit without a final stays "under inspection."
Does a building final close my trade permits?
Not necessarily. Electrical-only or mechanical-only permits still need their own finals. Check the portal after each final and save the results.
