Do You Need a Permit to Fill in a Pool? Rules, Costs, and Steps

In many parts of the United States, filling in a swimming pool requires a permit or approval from the local building department. Requirements depend on the pool type, how it will be removed or abandoned, and local rules for grading, drainage, utilities, and construction debris. A permit may be required even when the pool is no longer usable. Before work begins, homeowners should confirm the rules with their city or county and get any required approvals in writing.

Does Filling In a Pool Require a Permit?

Often, yes—but there is no single nationwide rule. Building and demolition permits are generally administered by local governments, which adopt and amend building codes to suit local conditions. The International Residential Code provides a model for residential construction regulations, but the locally adopted code and ordinances determine what applies to a particular property.

Some jurisdictions require a permit to demolish or permanently abandon a pool. Others may treat the work as grading, excavation, drainage, or construction debris removal and require approvals under those rules. A permit may also be necessary if the project affects a retaining wall, fence, electrical system, gas line, plumbing, sewer connection, or protected tree.

Even if a homeowner plans to do the work personally, that does not automatically create a permit exemption. A contractor’s license or professional status also does not replace required permits. The safest first step is to contact the building department for the property’s exact address and describe the intended method—not simply say the pool will be “filled in.”

What “Filling In a Pool” Can Mean

Local officials may distinguish between several approaches, and the distinction can affect the permit, inspections, and future use of the site.

• Partial removal and backfill: The pool shell is opened or partly demolished, and the cavity is filled with approved material. This is sometimes called abandonment or partial demolition.
• Complete removal: The pool structure and associated materials are removed, then the excavation is filled and compacted.
• Conversion: The pool is adapted for another use, such as a pond or water feature. This may involve separate plumbing, safety, electrical, and land-use requirements.
• Temporary closure: The pool remains in place but is drained, covered, or otherwise taken out of service. This is not the same as permanent removal and may still be subject to pool-safety rules.

These terms are not interchangeable in every jurisdiction. A partial-fill method may leave buried concrete and could affect whether the property can later support a house, garage, addition, or other structure. The local building department should confirm what methods it accepts and how the completed work must be documented.

Why Local Authorities Regulate Pool Removal

A swimming pool is a substantial excavation and structure. Removing or abandoning it can affect public safety and the stability and drainage of the property. Permit review helps the jurisdiction check that the work will not create a hazard or interfere with nearby land and infrastructure.

• Ground stability: Poorly compacted fill can settle over time, damaging landscaping, pavement, fences, or future construction.
• Drainage: Improper grading can direct water toward a home, neighboring property, or public right of way.
• Utilities: Pool pumps, lights, heaters, gas lines, and plumbing may need to be safely disconnected or capped.
• Water disposal: Discharging pool water into a storm drain, street, or sewer may be restricted or require specific procedures.
• Environmental and site rules: Flood zones, wetlands, shoreline areas, historic districts, easements, and tree protections can trigger additional reviews.

What Permits and Approvals May Be Needed?

The building department can identify the required approvals, but a pool-fill project may involve more than one agency. Requirements commonly depend on the property’s location and the work plan.

This list is not universal. A jurisdiction may combine reviews into one permit, require a site plan, or impose additional conditions. It may also require an inspection before the excavation is covered, so scheduling matters.

How to Find Out Whether a Permit Is Required

1. Contact the building department. Use the city or county website to find the department responsible for permits. If the property is in an unincorporated area, the county may have jurisdiction.
2. Describe the proposed method. State whether the pool is in-ground or above-ground, whether the shell will be removed or left partly in place, and what material will be used as fill.
3. Ask which agencies must review the work. Check separately about grading, drainage, electrical and plumbing disconnections, water disposal, and site-specific restrictions.
4. Request the submittal requirements. The department may ask for a site plan, photographs, contractor information, a fill specification, disposal details, or a compaction plan.
5. Confirm inspections and closeout documents. Ask whether officials must inspect the open excavation, utility disconnections, fill placement, or final grading—and whether a final approval will be issued.

Homeowners should keep permit approvals, inspection records, contractor invoices, and photographs. These documents can help explain the work to future buyers, insurers, or building officials. They do not replace any disclosure obligations imposed by state or local law.

Typical Permit Application Information

Application requirements vary, but a clear project description helps officials assess the work. A site plan may need to show the pool, house, property lines, access route, drainage features, and nearby utilities. The application may also ask for the pool’s dimensions and depth, the proposed demolition approach, and the source and type of fill material.

For a partial-fill project, the jurisdiction may specify how the shell must be opened to allow drainage, how much material must be removed, or what material can remain. It may require clean, approved fill placed in layers and compacted to a stated standard. Those details are local requirements, not assumptions a contractor should make without checking.

If the property will be built on later, the homeowner should tell the building department before selecting a fill method. A future foundation, addition, driveway, or accessory structure may require different engineering or complete pool removal. A geotechnical professional or structural engineer may be appropriate where soil conditions or future construction make settlement a concern.

Safety and Environmental Steps Before Work Begins

Pool demolition involves heavy equipment, excavation, electrical systems, and potentially pressurized or fuel-fired equipment. The project should not begin until the required permits are issued and the work area is planned.

• Locate underground utilities. In the United States, calling 811 before digging connects callers with the local one-call utility notification service. The required advance notice and process vary by state. Private lines, such as some pool circuits or irrigation pipes, may not be marked by public utilities, so homeowners should ask how those are located.
• Disconnect utilities safely. Electrical, gas, and plumbing work should be handled by qualified professionals where required. Equipment should not be assumed safe simply because it is switched off.
• Follow local water-disposal rules. Pool water can contain disinfectants and other treatment chemicals. Ask the local sewer or stormwater authority where and how it may be discharged; rules can differ even between neighboring communities.
• Manage demolition materials properly. Concrete, metal, decking, liners, and equipment should be sorted and disposed of according to local requirements. Do not assume that buried debris is acceptable fill.
• Check for hazardous materials where relevant. Older structures or associated buildings may contain regulated materials. The U.S. Environmental Protection Agency provides guidance on lead-based paint and asbestos; suspected materials should be assessed and handled under applicable rules before demolition.
• Protect workers and neighbors. Excavations, dust, noise, truck access, and open pits create risks. Contractors should use suitable barriers and follow applicable safety requirements.

What Can Happen If Work Starts Without a Permit?

Unpermitted work can lead to a stop-work order, fines, required inspections, or a demand to expose or redo work that has already been covered. The homeowner may also face difficulty obtaining approval for future construction if officials cannot verify how the pool was abandoned or whether utilities were disconnected correctly.

Unpermitted work can create practical complications during a property sale or insurance review. A future buyer or inspector may ask for evidence that the pool was removed legally and that the site was properly filled. These outcomes depend on local law and the facts of the project, but checking first is usually less disruptive than resolving a violation later.

How Much Does a Pool-Fill Permit Cost?

Permit fees are set locally and can depend on project value, excavation size, review type, and inspection needs. Some jurisdictions charge a flat fee; others calculate fees from a published schedule or require separate fees for grading, electrical, plumbing, or demolition permits. Additional costs may include engineering plans, utility disconnections, testing, and waste disposal.

There is no reliable national permit price. The local fee schedule is the best source for a current estimate. A contractor’s project quote should identify permit fees and clarify whether the homeowner or contractor will submit the application and arrange inspections.

Questions to Ask the Building Department and Contractor

• Is a permit required for this exact removal or abandonment method at this address?
• Does the project need separate grading, drainage, electrical, plumbing, or environmental approval?
• Can any part of the pool shell remain underground, and what openings or demolition are required?
• What fill materials are allowed, and are placement, testing, or compaction records required?
• Which inspections must occur before the excavation is covered?
• How should pool water and demolition debris be handled?
• Will the completed site be eligible for a future building permit, and what records should be retained?

Contractors should be asked to explain their proposed method, identify who obtains permits, and provide proof of required licensing and insurance. The homeowner should verify permit issuance directly with the jurisdiction rather than relying only on a verbal assurance.

Reliable Sources for Local Requirements

Local building and planning department websites are the primary sources for permit rules, applications, fees, and inspections. The International Code Council’s International Residential Code information provides context on the model code used by many jurisdictions, but local adoption and amendments control. For digging, Call 811 connects users with state-specific utility notification services. The EPA’s lead information and asbestos guidance explain federal resources for these hazards; state and local requirements may also apply.
