Building Permit Fees in Louisville, KY (2026)

Louisville Metro Construction Review permit fees (source retrieved Sep 1, 2026). Louisville Metro Department of Codes and Regulations, Construction Review is the office for this fee.

For a covering-only reroof on this path, a permit is required. A covering-only reroof is not on the per-square-foot occupancy table, so this page uses the partial-alteration / non-calculable square footage formula.

The formula is $50 plus $2.50 per $1,000 of job value, with a $75 minimum building fee. The official fee band is $75 / $80 / $105.

The typical project value is $12,000. The job values used for this fee are $8,000 low, $12,000 typical, and $22,000 high.

Walk the typical first. The $12,000 typical job is $50 + 12 x $2.50 = $50 + $30 = $80.

The typical fee is $80. The official line item (Partial alteration $50 + $2.50 per $1,000) is that same $80 and is already included in the typical total, so it is not added a second time.

Then the low job. The $8,000 low job is $50 + 8 x $2.50 = $70.

That $70 is under the $75 minimum, so the low fee is $75 and not $70. Then the high job.

The $22,000 high job is $50 + 22 x $2.50 = $50 + $55 = $105. The high fee is $105.

The $105 high is not added on top of the $80 typical. Those three results are separate bands.

The $75 low, the $80 typical, and the $105 high are not stacked on one permit. Count thousands of job value, multiply by $2.50, and add the $50 base.

Twelve steps at the typical job make the $30. Eight steps at the low job make the $70 that the $75 minimum replaces.

Twenty-two steps at the high job make the $55. Because the fee follows job value, a bigger contract value raises the fee at $2.50 per $1,000.

Roof area is not a direct input to this listed permit total. Documented roof sizes of 1,000 / 1,500 / 1,800 sq ft only matter through the job value.

They do not set a separate square-foot fee. This page does not state a separate plan-review fee, a technology fee, or an inspection add-on for this path.

This page does not invent plan-review add-ons. This page does not invent technology fees.

This page does not invent a fee beyond the official $75 / $80 / $105.

• Typical 3-ton combination (or heat pump) $105.
• Low $105.

High furnace + separate AC = $105+$50=$155.

200 sf $0.105=$21 → $75 min. 320 sf=$33.60 → $75.

400 sf=$42 → $75. Low=typical=high $75.

Louisville Metro Construction Review permit fees (source retrieved Sep 1, 2026). Interior remodel on this row is a partial alteration.

The fee is based on the project valuation and a permit is required on the official typical path, where the low fee is $87.50, the typical fee is $137.50, and the high fee is $237.50. The official typical project value is $35,000.

Listed assumed valuations are $15,000 low, $35,000 typical, and $75,000 high. The published partial-alteration line is $50 plus $2.50 per $1,000 of estimated cost, and the minimum building fee is $75.

Interior remodel is a partial alteration (sf of the whole building is not the fee basis). Walk the fee in three steps on the typical path.

1. Step 1: confirm the job is a partial alteration, so the fee uses the estimated cost of the interior remodel rather than square footage of the whole building.
2. Step 2: count thousands at $35,000 (= 35).
3. Step 3: apply $50 + $2.50 x 35 = $137.50, which is the typical fee of $137.50.

The $75 minimum does not bind on that typical band, because $137.50 is above $75. The official extra named Partial alteration $50 + $2.50 per $1,000 is $137.50, and its note is Min $75.

Included. That $137.50 is the typical total.

It is not added a second time. Low uses the same partial-alteration formula.

Count thousands at $15,000 (= 15). Apply $50 + $2.50 x 15 = $87.50, which is the low fee of $87.50.

The $75 minimum does not bind, because $87.50 is above $75. High uses the same partial-alteration formula.

Count thousands at $75,000 (= 75). Apply $50 + $2.50 x 75 = $237.50, which is the high fee of $237.50.

The $75 minimum does not bind, because $237.50 is above $75. The $75 minimum does not bind on any listed band.

The $237.50 high is not added on top of the $137.50 typical. Electrical / HVAC are separate trade permits.

They are not computed into the official $87.50, $137.50, and $237.50 totals. Cabinets-only may not need a building permit.

That cabinets-only path is not the low fee, the typical fee, or the high fee, and this note does not add a $0 line. This note does not invent a fee beyond the official $87.50, $137.50, and $237.50 totals.
