Permits and Inspections is how projects get red tagged, deals fall through, and insurance claims get denied. This is the straight guide to when you need a permit, how inspections work, what reviewers look for, and how to keep your project moving. For structural changes that require sizing, shoring, and documented load paths, see our structural carpentry page.
When Permits and Inspections are required
If the work affects structure, life safety, or building systems, assume you need a permit.
| Work type | Permit needed | Notes |
|---|---|---|
| Load bearing wall removal, beams, headers | Yes | Often needs engineer letter and plan sheet |
| New openings, window or door resizing | Yes | Header size and shear transfer reviewed |
| Deck framing, ledgers, stairs, railings | Yes | Setbacks and guard details checked |
| Electrical circuits, panel work | Yes | Separate electrical permit and inspections |
| New plumbing or major reroutes | Yes | Pressure tests and venting reviewed |
| HVAC equipment, duct changes | Yes | Manual J/S, combustion air in some areas |
| Kitchens and baths with layout changes | Yes | Often one master permit plus sub-trades |
| Roofing, siding, windows like for like | Sometimes | Local rules vary for like-for-like |
| Painting, flooring, cabinets only | No | Cosmetic does not require permits |
When in doubt, ask the building department. Getting told to stop mid job is the expensive route.
What goes in your permit packet
Reviewers want to see that the loads are carried and systems are safe.
- Floor plan with dimensions and labeled rooms
- Framing plan for openings, beam sizes, posts, and load path to footing
- Section detail showing how members connect and where bearing occurs
- Mechanical, electrical, and plumbing scope if changed
- Engineer letter or stamped drawings when required
- Product sheets for special items like intumescent coatings or fire rated assemblies
Keep drawings clean and readable. Call out any existing conditions that are not standard.
The Permits and Inspections steps that keeps projects moving
Inspections follow the order of hidden work. Book early to avoid idle days.
- Footing inspection if new pads or foundations are poured
- Rough framing once beams, headers, posts, and fasteners are in
- Rough MEP for electrical, plumbing, HVAC before insulation
- Insulation and air sealing where required
- Final inspection after finishes, trim, and devices are installed
Do not cover work before it passes. Photos rarely substitute for a missed inspection.
How reviewers think
Inspectors check three things every time.
- Load path is continuous from beam to post to footing
- Connections use listed hardware and correct fasteners, not substitutes
- Clearances and fire safety are met around panels, appliances, and penetrations
Meet the code, not opinions. If you disagree, ask for the specific section the note references and fix to that standard.
Common fails that waste time
- No permit card or plans on site
- Posts sitting on slab without a footing
- Missing joist hangers, wrong nails, or skipped straps
- Over notched or over bored joists for plumbing
- Unprotected deck ledgers or missing lateral load connectors
- Covering rough work before the inspection window
Fix these on paper during planning. They are cheap to prevent and costly to correct later.
Engineer letters and when you need one
You need stamped calcs or details when spans are long, loads stack through multiple stories, or the jurisdiction requires it. Removing load bearing walls, hiding beams in ceilings, or altering trusses often triggers engineering. We coordinate with the engineer and build to the stamped details under our structural carpentry scope.
Timelines and fees
- Permit review: a few days to a few weeks depending on jurisdiction and workload
- Inspections: book 24 to 72 hours ahead, some cities allow same day if scheduled early
- Fees: based on scope and valuation, plus trade permits for electrical, plumbing, and HVAC
Plan your start date around approval, not the other way around.
Homeowner responsibilities that keep you compliant
- Post the permit card and keep stamped drawings on site
- Clear access to work and panels on inspection day
- Be present or have someone who can answer scope questions
- Do not make scope changes without updating the permit
- Keep photos and approvals for your records and future resale
Closing out permits
A permit is not finished until the final is signed off.
- Address all inspector notes in writing
- Re-inspect promptly to avoid expiration
- Collect the final sign-off and keep it with your house documents
- If a permit lapses, apply for reactivation before you restart work
Selling a home with unpermitted work
Expect delays, credits at closing, or a requirement to open walls for inspection. Legalizing after the fact often costs more than doing it right the first time.
FAQ
Can I start demo while the permit is in review
Usually no for structural work. Some jurisdictions allow minor prep, but starting early risks a stop work order.
Do I need separate permits for trades
Often yes. Many cities issue one master building permit plus separate electrical, plumbing, and HVAC permits.
What if an inspector asks for something that was not on the plans
Ask for the code reference. If it applies, update the plan and install. If it does not, clarify with the plans examiner.
Will a hidden beam require more inspections
Yes. Expect detailed framing inspection for hangers, fasteners, and blocking before drywall.
