Pier Footing Permit & Inspection Requirements: What to Expect
Most deck and porch projects need a permit, and most permits come with a footing inspection before you’re allowed to pour — skip either step and you risk a stop-work order or trouble at resale.

Before your inspection, have your planned depth, diameter, and pier count ready — the concrete pier calculator can help you document your concrete volume if asked. This guide covers what the permit and inspection process typically involves.
Typical Permit Requirements by Project Type
| Project Type | Permit Typically Required? | Inspection Typically Required? |
|---|---|---|
| Attached deck, any height | Yes, in most jurisdictions | Yes — footing, framing, and final |
| Freestanding deck, elevated (over ~30 in.) | Yes, in most jurisdictions | Yes — footing at minimum |
| Freestanding deck, low/ground-level | Varies — some jurisdictions exempt low decks | Varies — check locally |
| Porch addition (roofed structure) | Yes, almost universally | Yes — often multiple inspections through the build |
| Repair/repour of an existing failed footing | Often required, especially for structural repairs | Often required |
These are general patterns, not a substitute for checking your specific local requirements — permit and inspection rules vary meaningfully between jurisdictions, sometimes even between neighboring towns.
Why Permits and Inspections Exist
A footing inspection exists specifically to verify, before it’s covered by concrete, that the hole meets the depth, diameter, and soil-bearing requirements your permit was approved for. Once concrete is poured, many of these details become difficult or impossible to verify without destructive testing — which is exactly why the inspection happens at the open-hole stage rather than after the fact. Beyond the immediate safety purpose, a documented, inspected permit history also matters at resale, where an unpermitted structural addition can complicate a home sale or insurance claim.
Permit and Inspection Terminology
| Term | What It Means |
|---|---|
| Building permit | Official approval to perform the construction, typically requiring submitted plans before work begins. |
| Footing inspection | An inspector’s visit to verify open, unpoured footing holes meet approved depth, diameter, and soil conditions. |
| Framing inspection | A later inspection checking the structural framing (posts, beams, joists) after footings are complete. |
| Final inspection | The last inspection confirming the completed structure matches approved plans and code. |
| Certificate of occupancy / completion | Official sign-off that the completed structure has passed all required inspections. |
Typical Inspection Sequence
Permit Application → Plan Review/Approval → Footing (Open Hole) Inspection → Pour Concrete → Framing Inspection → Final Inspection
The footing inspection specifically happens between digging and pouring — pouring before this inspection is completed is one of the most common permit violations on deck projects.
How to Navigate the Permit Process
- Contact your local building department before digging. Confirm whether your specific project needs a permit and what documentation (plans, engineering, soil report) is required to apply.
- Ask specifically about footing inspection timing. Confirm whether the inspector needs to see the open hole before you pour, or whether some jurisdictions allow other verification methods.
- Ask what the inspector will be checking. Depth, diameter, soil condition, rebar presence, and gravel base are common items — knowing this in advance helps you prepare the site properly.
- Check typical inspection scheduling lead time. Some departments need several days’ notice, which affects how you sequence digging multiple piers around a single inspection visit.
Example 1: Standard Attached Deck
- Project: Attached deck, 8 piers
- Permit: Required, submitted with a basic deck plan
- Inspection: Footing inspection scheduled after all 8 holes were dug, before any pouring began
Digging all holes before scheduling a single footing inspection is a common, efficient approach when the local department allows batching multiple footings into one inspection visit.
Example 2: Low Freestanding Deck, Exempt Jurisdiction
- Project: Freestanding deck, 18 in. off grade
- Local rule: Decks under 30 in. and not attached to the house are exempt from permit requirements
- Permit: Not required, confirmed directly with the building department
Exemption thresholds vary significantly by jurisdiction — always confirm the specific local threshold rather than assuming a general rule applies everywhere.
Example 3: Repour After a Failed Footing
- Project: Repouring a heaved pier from an earlier project
- Permit: Required, since this was a structural repair to an existing permitted structure
- Inspection: Footing inspection required on the new, corrected depth before repouring
A repair to a structural element often triggers the same permit and inspection requirements as new construction, even though it’s a smaller-scale fix.
Have your planned dimensions ready for inspection — use the concrete pier calculator to document your concrete volume alongside your depth and diameter for the record.
What Inspectors Commonly Check
| Item | What’s Verified |
|---|---|
| Depth | Meets the approved frost-depth and bearing-depth requirement for the permit |
| Diameter | Matches the approved plan’s specified footing size |
| Soil condition | Bearing soil is firm and undisturbed, not loose fill |
| Rebar (if required) | Correct size, count, and placement per approved plan |
| Gravel base (if required) | Present and of adequate thickness per local code |
| Spacing/layout | Matches the approved deck plan’s pier positions |
Alternative: Owner-Builder Permits vs. Contractor-Pulled Permits
In many jurisdictions, a homeowner doing their own work can pull an “owner-builder” permit directly rather than having a licensed contractor pull it on their behalf. This is worth checking if you’re planning a DIY pier project, since the process, required documentation, and sometimes the fee structure can differ from a contractor-pulled permit. Some jurisdictions require an owner-builder to sign an acknowledgment of responsibility for code compliance — ask your building department about this option specifically if you’re doing the work yourself.
Common Permit Mistakes
- Pouring before the footing inspection is completed. This is one of the most common violations, and correcting it after the fact can mean breaking out already-poured concrete.
- Assuming a low or freestanding deck is automatically exempt. Exemption thresholds vary significantly by jurisdiction — confirm rather than assume.
- Not scheduling inspections with enough lead time. Some departments require several days’ notice, which can delay a project if not planned for.
- Skipping a permit for a “small” project. Even modest additions can trigger permit requirements, particularly if attached to the house.
- Not keeping inspection records. Documentation of passed inspections matters for resale and insurance — keep copies of permit approvals and inspection sign-offs.
- Assuming a repair doesn’t need the same permit process as new construction. Structural repairs, including repouring a failed footing, often require the same permit and inspection steps.
Permit Requirement by Project Type: Decision Table
| Situation | Typical Requirement |
|---|---|
| Attached deck or porch, any height | Permit and inspections required in nearly all jurisdictions |
| Elevated freestanding deck | Permit and footing inspection typically required |
| Low, ground-level freestanding deck | May be exempt — confirm with local building department |
| Structural repair or repour | Often requires the same permit process as new construction |
| Uncertain about your specific project | Contact the building department directly before starting |
Other Factors to Consider
- Local jurisdiction variation. Requirements can differ significantly even between neighboring towns or counties — never assume a rule from one place applies elsewhere.
- Homeowners association rules. Some HOAs have additional approval requirements separate from municipal permits — check both if applicable.
- Insurance implications. Unpermitted structural work can complicate insurance claims related to the structure later.
- Resale disclosure requirements. Many areas require disclosing unpermitted work when selling a home, which can affect buyer negotiations.
- Timeline impact. Permit approval and inspection scheduling both add time to a project — factor this into your overall build schedule.
Navigating Permits and Inspections: Step by Step
- Contact your local building department to confirm whether your project needs a permit.
- Submit required plans and documentation for approval before beginning work.
- Dig your footing holes to the approved depth and diameter.
- Schedule and pass the footing inspection before pouring any concrete.
- Pour concrete once the inspection has cleared you to proceed.
- Calculate your concrete volume with the concrete pier calculator to have documented figures on hand if requested.
- Continue through framing and final inspections as required for your project type.
- Keep copies of all permit and inspection records for future reference.
Frequently Asked Questions
Do all deck projects need a permit?
Not necessarily — some jurisdictions exempt low, freestanding decks below a certain height, but most attached decks and any elevated structure typically require one. Always confirm with your local building department for your specific project.
Can I pour concrete before the footing inspection?
No — pouring before a required footing inspection is one of the most common permit violations, since it makes it difficult or impossible to verify depth and soil condition afterward without breaking out the concrete.
What happens if I skip the permit process entirely?
Consequences vary by jurisdiction but can include stop-work orders, fines, required removal or correction of the work, and complications at resale or with insurance claims related to the unpermitted structure.
Can a homeowner pull their own permit for DIY work?
In many jurisdictions, yes — this is often called an owner-builder permit. Check with your local building department, since the process and any required acknowledgments can differ from a contractor-pulled permit.
How much notice do I need to schedule a footing inspection?
This varies by jurisdiction, from same-day scheduling to several business days’ notice — check with your local building department and plan your digging schedule around their typical lead time.
Does a repair to an existing footing need the same permit process?
Often yes, particularly for structural repairs like repouring a heaved or cracked pier — check with your local building department, since repair permit requirements can differ slightly from new construction.
