Deck Construction Permits in Baton Rouge
Local Rule
East Baton Rouge Parish Permits and Inspections Division (City-Parish Department of Development)
Baton Rouge is governed as a consolidated city-parish, and the Permits and Inspections Division's own "Understanding Permit Requirements" sheet exempts a deck from a building permit only when it stays under 200 square feet, no more than 30 inches above grade, and, distinctively, sits within a buildable area of the lot, meaning even an otherwise-exempt small deck can lose that status if it falls in a setback or easement rather than the general buildable envelope. Applications go through the MyGovernmentOnline (MGO) portal, and the city-parish offers an Expedited Plan Review option that returns a residential review in about three business days, much faster than the standard timeline. The city's own fee schedule sets a $125 minimum permit fee for additions and renovations (which would apply to most attached decks) and $80 minimum for new stand-alone buildings, with new-building work priced at $0.50 per square foot; a 5 percent surcharge applies to credit card payments, plus a flat $15 technology fee.

The only exception is a small freestanding platform 200 sq ft or smaller and no more than 30 inches above grade that is not attached to the house (IRC R105.2); any attached or elevated deck needs a permit.
