# Well and septic permits in Wake County

Triangle building

Resolve the wastewater approval before the building permit. Coordinate the well and septic layout on the same site plan, then track their separate inspections.

You are planning a house on a Wake County lot without approved sewer service. Resolve the septic approval before you rely on a building-permit date.

North Carolina generally requires wastewater construction authorization before issuing other construction permits. State law provides alternatives for existing systems and private permitting. [G.S. 130A-338](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_130A/GS_130A-338.html) sets that order.

Plan the well and septic system together, but track each approval separately. Show the house, access, water supply, wastewater system, and repair area on the same plan. Give that same plan to the people responsible for evaluating, permitting, and installing each system.

## Confirm septic approval before the building permit

If you use the local health department, you need an improvement permit and construction authorization. The improvement permit addresses site suitability and the proposed facility. The construction authorization allows installation.

State law prohibits starting the house or wastewater-system construction without those approvals, unless a statutory alternative applies. [G.S. 130A-336](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_130A/GS_130A-336.html) describes those requirements.

Identify the parcel and the office that issues its building permit. Wake's [application guidance](https://www.wake.gov/departments-government/onsite-water-protection/septic-system-permitting/apply-permit) directs applicants to town planning departments for the order of operations. For projects in county jurisdiction, it describes applying through the Permit Portal for wastewater and building or zoning permits.

Check when you can apply as well as when the permit can be issued. Raleigh requires [Wake County approval for property with a private well or septic service before applying to the city](https://raleighnc.gov/permits/services/how-get-residential-permit). Confirm your jurisdiction's instructions before submitting. Our [Wake County building-permit guide](/guides/wake-county-building-permits/) addresses who issues the building permit.

## Know what each septic approval answers

The [improvement-permit and construction-authorization statute](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_130A/GS_130A-336.html) and [operation-permit statute](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_130A/GS_130A-337.html) establish different approvals. Ask the issuer which document you have and which you still need.

| Document | What it addresses | Your next check |
| --- | --- | --- |
| Improvement permit (IP) | Proposed facility, wastewater system and location, design flow, and conditions | Does it match the house and site you intend to build? |
| Construction authorization (CA) | Authorization to install under applicable requirements and conditions | Are conditions resolved and the installer working from the accepted design? |
| Operation permit (OP) | Authorization following the installed-system review | Is the required final approval in the project closeout file? |

Under [G.S. 130A-336](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_130A/GS_130A-336.html), the CA can be issued with the IP. Do not assume a document labeled improvement permit includes it. Ask for both documents, their attached plans, and any conditions.

Before purchasing a lot with an existing approval, send the documents to the issuing office. Ask whether the approval remains valid for your proposed facility and layout. The statute allows the approval to transfer with ownership if its site, facility, and control conditions still hold. If you change the house plan, ask whether the approval still applies.

## Assign the soil evaluation and permitting roles

If you use the county permitting process, the local health department evaluates the site under [G.S. 130A-336](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_130A/GS_130A-336.html). You can also submit qualifying professional evaluations under [G.S. 130A-335](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_130A/GS_130A-335.html). That law describes licensed soil scientist and licensed geologist evaluations within their scopes of practice.

Ask whether the professional will evaluate the site or handle the full private permitting process. Wake describes [private-sector permitting options](https://www.wake.gov/departments-government/onsite-water-protection/septic-system-permitting/apply-permit/private-sector-permitting-options), including an engineered option. Its guidance assigns design modifications and inspections to the engineer for that option. Get the permitting process and the professional's responsibilities in writing.

Before hiring, request these answers:

- Are you evaluating soils, designing the system, administering a private permit path, or providing several services?
- Who submits the application and supporting plans?
- Who issues each approval and responds to comments?
- Who inspects installation before the installer covers the system?
- What documents will you provide, and what conditions will still need to be met?

The [site-evaluation provisions in G.S. 130A-335](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_130A/GS_130A-335.html) identify soil characteristics, topography, wetness, depth, restrictive horizons, and space. Ask the evaluator what access or excavation is needed for this site and its repair area. Do not substitute a soil-map screenshot for the required field evaluation.

## Hand the authorization to the installer before sitework starts

Give the septic installer the accepted design, IP and CA or applicable private-path documents, permit conditions, and current site plan. Ask the installer to identify the revision it will build. Resolve a conflict with the authorizing professional or office before dispatching the crew.

G.S. 130A-335(a7) assigns preconstruction notice to the wastewater contractor and addresses changed site conditions. Its conditions include wetness, grading, and compaction that can affect the evaluation. Confirm the notice recipient and inspection owner for your permit path before mobilization. [Contractor notice and changed-site provisions](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_130A/GS_130A-335.html).

Walk the site with the installer and [excavation crew](/trades/excavation/). Have the authorizing party identify the initial system, repair area, well location, access route, and project-specific no-disturb limits. Mark those areas on the plan distributed to each crew. Ask that party before changing routes, stockpiling, grading, or driving equipment through a protected area.

Use a handoff record like this:

| Handoff item | Confirm before work starts | Named owner to record |
| --- | --- | --- |
| Accepted design | Current drawing, approval documents, system location, and permit conditions | Permit coordinator and installer |
| Protected areas | Initial system and repair area, well location, no-disturb limits, and access route | Authorizing party and site superintendent |
| Excavation boundary | Who excavates, installs components, restores the site, and protects later work | Installer and excavation foreman |
| Inspection hold | Who receives notice, inspects the exposed system, and closes corrections | Inspector or responsible professional for this permit path |
| Release evidence | Required written acceptance and final documents before covering or use | Permit coordinator and authorizing party |

For a county inspection or qualifying private inspection, follow the applicable statutory process before covering the system. G.S. 130A-337 identifies private inspection alternatives and their written records. Ask the county or authorizing professional which route and documents apply. [Inspection and verification provisions](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_130A/GS_130A-337.html).

File this record with the [trade handoff checklist](/tools/trade-handoff-checklist/). Use [Wake County building permits](/guides/wake-county-building-permits/) to establish the building-permit jurisdiction. The [Raleigh](/triangle/raleigh/) and [Wake Forest](/triangle/wake-forest/) market guides help you identify the separate local contacts; they do not replace the wastewater approval.

## Put the site details in one submission package

Use this checklist to prepare, then get the issuer's current submission requirements. You still need the issuer's application form.

1. Identify the parcel, owner, address, and building-permit jurisdiction.
2. Supply the current survey or site plan and the proposed house layout.
3. State the intended bedroom count and any planned additional dwelling or water-using facility.
4. Show the proposed well, driveway, structures, and wastewater areas together.
5. Ask the evaluator to identify the initial system and repair area on the plan you will distribute.
6. Keep the plan revision, application numbers, issuer, and remaining conditions in one project record.

Before moving a driveway, adding a detached structure, or changing the house footprint, send the revised layout back for review. Use the [site-readiness checklist](/guides/site-readiness-checklist/) to communicate protected areas to the sitework crew. Ask the permit issuer to confirm changes before you give the crew a revised instruction.

## Put well approval on the same schedule

A new private drinking-water well requires a local health department construction permit. The department performs a site investigation before issuing it. When a wastewater system is present or proposed, the application needs a plat or site plan. [G.S. 87-97](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_87/GS_87-97.html) establishes those requirements.

Wake says it issues the [well permit with the wastewater permit, using the same site plan](https://www.wake.gov/departments-government/onsite-water-protection/groundwater-protection-and-wells/well-permits-fees-and-approvals), when the project needs both. Confirm the approved location and testing conditions with the well contractor before drilling. Submit any proposed well relocation for review.

Ask the contractor and county to agree on inspection notices, wellhead completion, disinfection, flushing, and sampling. Wake's guidance describes the grout and wellhead inspection steps. State law also provides a conditional [grouting-certification procedure and a variance exception](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_87/GS_87-97.html). Ask the contractor and county which procedure applies to your well.

Reserve time after drilling for completion and water testing. Wake says [water-quality results may take three to four weeks](https://www.wake.gov/departments-government/onsite-water-protection/groundwater-protection-and-wells/well-permits-fees-and-approvals). That is the county's stated wait for lab results. It does not cover the whole project or guarantee a completion date.

## Collect final approvals before the handoff

For the county septic path, state law requires inspection before the system is covered and an operation permit before use. [G.S. 130A-337](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_130A/GS_130A-337.html) sets those requirements. If you use private permitting, get the required final documents from the professional.

For the well, [G.S. 87-97](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_87/GS_87-97.html) requires a certificate of completion before service. It also requires testing within 30 days after the certificate for a newly constructed well. Track completion, test results, and any required follow-up separately in your project record.

Request a closeout package containing the approved plans, installation records, final approvals, test results, and operating instructions. Ask the building-permit office what it needs for its own final review. Put those requirements into your [home-building sequence](/guides/home-building-sequence/) before setting the turnover date.
