Collier County Impact Fees: What New-Home Builders Pay

If you are buying a lot to build on, or selling one, there is a line in the budget that surprises people: impact fees. Collier County charges one-time impact fees on new homes to help pay for roads, schools, EMS, parks and other public facilities. Most are paid before the certificate of occupancy, fire impact fees are due when the building permit is issued, and builders know this whole stack when they decide what they can pay for land. Here is how Collier County impact fees on a new home work, straight from the county’s own page.

What impact fees pay for

Impact fees are charged on new construction so growth helps pay for the public facilities it uses. Collier County’s residential schedule breaks them out by category, including roads, schools, EMS, law enforcement, the jail, libraries, community and regional parks, and government buildings. Homes that connect to county water and sewer also pay water and sewer impact fees.

The county publishes the current residential schedule, the impact fee studies behind each category, and an online calculator on its Impact Fees page. I am not going to quote a total here, because the amount depends on the home’s size, its location, its fire district and whether it connects to county water and sewer. The county’s impact fee calculator walks you through those questions. As of today the page lists the residential schedule effective May 1, 2026, and new water and sewer impact fee rates effective December 1, 2026.

When they are paid

This is the part people get wrong. In unincorporated Collier County, per the county page:

• Impact fees on a building permit are paid prior to issuance of the certificate of occupancy (CO).
• Fire impact fees, which are collected for the independent fire districts, are due when the building permit is issued.
• Permits in the City of Naples or the City of Marco Island pay impact fees at permit issuance.
• The fees are calculated at the rates in effect when the permit is submitted or when the CO is issued, whichever is less.

Fire fees are separate

Fire protection in much of Collier County comes from independent fire districts, not the county. The county collects fire impact fees on their behalf, and the amount depends on which district the lot is in. The county posts a fire district map on the same page. Check it before you budget, because a lot a few miles away can sit in a different district.

Size, guest houses and water and sewer

A few details from the county’s FAQ that matter on Estates lots:

• Single-family homes have two tiers: under 4,000 square feet of living area, and 4,000 square feet or more.
• A guest house is treated as an addition to the main home. Fees apply if the combined living area moves the property into the higher tier.
• County impact fees are not assessed on detached garages or sheds, though fire impact fees may apply depending on the district.
• Enclosing a lanai with air conditioning or converting a garage counts as new living area.
• Where county water or sewer is available, new construction must connect and pays those impact fees. The county notes this applies in the former FGUA utility area of Golden Gate City. Many Golden Gate Estates homes use a private well and septic instead.

Why land offers reflect it

A builder looking at a lot is working backward from what a finished home will sell for. Out of that number come construction, site work, permits, impact fees and profit. What is left is what the builder can pay for the land. That is one reason vacant land in the Estates often sells for less than buyers expect when they compare it to a finished home nearby. My cost to build in Golden Gate Estates guide walks through the other lines in that budget, and my Golden Gate Estates acreage guide covers the lot checks. If you are shopping, see what is available on my Naples land for sale page.
