How each fee is calculated

Roof replacement

Fee basis: Flat fee.

Project value on this row: low $8,000, typical $12,000, high $22,000.

City of Baton Rouge / Parish of East Baton Rouge Permit & Inspection Fees (source retrieved Sep 1, 2026). City of Baton Rouge, not New Orleans.

The official typical path is the Title 8 all-other residential building permit plus the technology fee. This is a flat fee, and a permit is required for a roof replacement (Act 239 / city roof-permit notice).

The low, typical, and high fees are $150, $150, and $150. The official typical project value is $12,000.

Listed assumed valuations are $8,000 low, $12,000 typical, and $22,000 high. Valuation is not an input on this flat path, so those amounts do not change the $150 / $150 / $150 listed fees.

The current published fees page has no separate reroof-specific dollar. The Title 8 all-other residential building permit is $125 (additions, renovations, and other residential building work) and is included.

The technology fee from the All Permits table is $25 and is included. $125 + $25 = $150. Walk the three listed bands.

  • Low $8,000: valuation is unused; $125 building permit + $25 technology fee = $150, so the low fee is $150.
  • Typical $12,000: valuation is unused; $125 building permit + $25 technology fee = $150, so the typical fee is $150.
  • High $22,000: valuation is unused; $125 building permit + $25 technology fee = $150, so the high fee is $150.

The $150 high is the same total as the $150 typical and is not added on top of it. The residential remodel rate of $0.80/sf is deliberately not applied; that would price 1,500 sf of roof as an interior remodel.

Roof size does not change the $150 on this row. Those two included lines are the only dollars in the $150 total.

Cite the City of Baton Rouge / Parish of East Baton Rouge Permit & Inspection Fees page for the $125 and $25 lines used on this row. This note does not invent a fee beyond the official $150 total.
