The permits, in order

Every inground pool project moves through the same regulatory sequence. The specifics vary by jurisdiction, but the structure is consistent: apply, get approved, build in phases, pass inspections at each phase, receive a certificate of completion at the end.

Building permit: the foundation of everything else

The building permit is the primary permit. It covers the pool shell structure, its location on your lot (setback compliance), zoning rules (lot coverage limits, accessory structure regulations), and drainage. Your city building department issues it if you live in an incorporated area; your county building department if you are in unincorporated territory.

Your pool contractor pulls this permit. Their contractor license number appears on it, making them the legally responsible party for code compliance. The application requires a scaled site plan (typically 1"=20') showing property lines, the pool location with dimensions, equipment pad placement, existing structures with measured distances, utility easements, and a drainage plan.

Most jurisdictions require setbacks of at least 5 feet from the pool's water edge to any property line, 5-10 feet from the pool to any structure, and 10-25 feet from septic systems. Properties with wells typically face setbacks of 50-100 feet. Pools cannot encroach into utility or drainage easements.

Plan review runs 2-6 weeks in most jurisdictions. Phoenix processes standard residential pools in 10-15 business days, with some eligible for same-day over-the-counter permits. Los Angeles runs 15-25 business days for standard plan check, with an express option at roughly double the plan check fee. Suffolk County on Long Island requires both a town building permit and a separate Suffolk County Department of Health Services permit (under the Suffolk County Sanitary Code, Article 7), extending the total timeline to 4-10 weeks.

Permit fees follow three common structures: flat fees for swimming pools (most common), valuation-based fees calculated as a percentage of declared construction cost, or a combination with a base amount plus a plan check surcharge. Nationally, total permit costs for a standard residential inground pool run $500-$1,500. In Los Angeles, expect $1,500-$3,500+.

Electrical permit: the one that saves lives

Pool electrical work is governed by NEC Article 680 of NFPA 70 (the National Electrical Code). The 2020 edition is the most widely adopted as of 2025. A licensed electrician pulls this permit separately from the building permit.

The most complex requirement is the equipotential bonding grid (NEC Section 680.26), which connects all metallic pool components, the pool water itself, and all metal within 5 feet of the pool walls to a common ground. For vinyl liner and fiberglass pools (non-conductive shells), this requires a copper conductor grid of No. 8 AWG bare solid copper installed beneath the pool deck. GFCI protection is required on all receptacles within 20 feet of the pool and on all pool pump motors.

Fencing/barrier permit

Pool barrier requirements come from the ICC International Swimming Pool and Spa Code (ISPSC), Section 305, or from IRC Appendix G in jurisdictions that have adopted it. The standard across most of the country: a continuous barrier of at least 48 inches on the exterior side, with no openings allowing passage of a 4-inch sphere. Gates must be self-closing from any open position, self-latching with the mechanism on the pool side, and must open away from the pool.

Two states set the bar higher: California and Arizona both require 60-inch (5-foot) barriers. California's Swimming Pool Safety Act (Health & Safety Code sections 115920-115929, strengthened by AB 2977 in 2018) further requires at least two of seven specified safety features on all new residential pools.

The permit-pulling question

"Pulling permits" is industry shorthand for applying for and obtaining a building permit. In the standard arrangement, your pool contractor pulls the main building permit, the electrical subcontractor pulls the electrical permit, and the plumbing sub pulls the plumbing permit where one is required.

A contractor who suggests building without permits is the single clearest warning sign in pool construction. It typically means the contractor is unlicensed, lacks proper insurance, or plans to skip code-required safety features. The consequences of unpermitted pool work are severe: homeowners' insurance policies can deny claims on non-code-compliant structures, lenders can refuse to finance a home sale (FHA appraisal guidelines in HUD Handbook 4000.1 require code compliance), and building code violations can create negligence-per-se liability in injury lawsuits.

Common delays and how to avoid them

The most frequent cause of permit delays is an incomplete application. Missing site plans, incorrect dimensions, or absent engineering calculations trigger a plan check correction notice, and each round of corrections adds 1-3 weeks.

Other common delays: zoning variance requirements (can add months if a hearing is needed), understaffed building departments (a persistent issue since 2020), and environmental review layers for properties in flood zones, coastal areas, or near wetlands. Properties in FEMA Zone A/AE (the 100-year floodplain) need a floodplain development permit and potentially a "no-rise" certification. Properties in Zone V/VE (coastal wave action) face the most restrictive requirements.

The most effective way to reduce delays: confirm your property's flood zone status at the FEMA Flood Map Service Center (msc.fema.gov) and look up your local pool-related codes on Municode (library.municode.com) before your contractor starts the application. Knowing the requirements in advance means fewer correction rounds.

Tools to research your jurisdiction

Five free tools cover most of what you need to know before filing:

  • Municode (library.municode.com): Searchable municipal codes for 3,500+ local governments. Search for "swimming pool," "barrier," "setback," and "accessory structure" in your municipality's code.
  • FEMA Flood Map Service Center (msc.fema.gov): Enter your address to find your flood zone. Takes about 10 minutes.
  • County GIS parcel viewer: Search "[Your County] GIS parcel viewer" to see property boundaries, easements, and zoning overlaid on aerial imagery. Useful for measuring setback distances. Reference-grade only; not a substitute for a licensed survey.
  • 811 (call811.com): The federally designated Call Before You Dig service. Legally required in all 50 states before any excavation. Free. Call at least 2-3 business days before planned digging. Does not mark privately owned lines from the meter to your house; hire a private utility locator ($200-$500) for those.
  • ICC Digital Codes (codes.iccsafe.org): Free read-only access to the full ISPSC, IRC, and IBC. Useful for reading the actual barrier and setback code language your jurisdiction has adopted.
