Casa Grande Building Permit and Impact Fees for a New Home: The ICC Valuation Table and Development Fees

A new home in Casa Grande, in Pinal County, carries two separate buckets of city money. First, a building permit and plan review fee, priced off the value of your construction. Second, development impact fees, the larger charge that pays for the roads, water, sewer, parks, and public safety your home will use. This page gives you the real basis for each from the city's official FY2025-26 schedule, so you can set a line item instead of guessing.

How Casa Grande calculates the permit fee

Casa Grande prices a new-home permit by construction valuation, and the city is specific about where that value comes from:

Building Permit fees are calculated on the values in the latest ICC Building Valuation Table, or upon the actual construction costs contained within a verifiable signed construction contract, whichever are less.

So the city sets your home's valuation from the ICC Building Valuation Table (the national cost-per-square-foot figures) or your signed contract, whichever is lower. The permit fee then comes off a tiered scale. For a home valued between $200,001 and $1,000,000, the fee is $1,800 for the first $200,000 plus $7.00 for each additional $1,000. For example, a home that values out at $450,000 pays $1,800 plus 250 times $7.00 ($1,750), so about $3,550 in building permit fee.

Plan review stacks on top. The city charges building plan review at 65 percent of the building permit fee. On that $450,000 home, the 65 percent plan review adds about $2,308, bringing the building-department total to roughly $5,858 before trade permits. Then add the technology recovery fee, which is "5% of the permit and land use application fees" with a $750 maximum, collected on all permits. Electrical, mechanical, and plumbing permits for a residence are $75 each. A Certificate of Occupancy issued with the building permit is "no charge, included in permit," while a temporary CO is $200.

The development impact fees are separate and larger

Impact fees are charges a city collects on new construction to fund the public infrastructure that growth requires. Arizona authorizes them under A.R.S. 9-463.05, which also forces a biennial audit of each city's fees. Casa Grande sets its impact fees in its Infrastructure Improvements Plan (IIP), a separate schedule from the building permit fee. The city's 2024 audit report confirms the categories in force. These include water, wastewater, and streets. Wastewater is charged by service zone, with a Zone A rate and a Zone B rate. The city's code is direct about timing:

Development impact fees shall be paid prior to issuance of a building permit.

So the impact fees are due up front, as part of the cash you bring to pull the permit, not a later bill. They are usually the largest single city charge on the whole project, well above the permit and plan review fees. The exact per-unit dollar amounts live in the adopted IIP schedule rather than in the consolidated fee schedule, so pull the current figure for your address and service zone from the city.

There is a protection built in. Under A.R.S. 9-463.05, once the first building permit issues for a platted single-family development, the city locks that development's impact fee schedule for 24 months at the permittee's request.

When these fees come into play

• At permit application. The city sets your valuation, then invoices the permit fee, the 65 percent plan review, and the 5 percent technology recovery fee.
• Before the permit issues. Development impact fees are collected before the permit is released, so budget them as start-of-construction cash.
• Watch the service zone. Casa Grande's wastewater impact fee differs by zone, and the 2024 audit found a few permits charged the wrong zone, so confirm your zone in writing.

What this means for you

Budget the permit fee and the 65 percent plan review together, since the plan review tracks the permit, then add the 5 percent technology recovery fee. Get an honest valuation, because the city uses the ICC table value when it is lower than your contract, and the fee follows the valuation. Treat the development impact fees as the big, up-front number, and ask the city for the current IIP amount for your specific address and service zone, because that figure is not in the consolidated fee schedule and it resets on its own cycle. If you have a platted single-family lot, ask the city to lock your impact-fee schedule for 24 months when your first permit issues.
