Modular accessory dwelling unit — New Orleans, LA
Last updated: September 24, 2026
What affects the price
Building an ADU is a custom project, so costs vary based on your specific choices. Site conditions are the biggest factor; if your land requires significant grading, utility extensions, or foundation work, those expenses add up quickly. Choosing high-end finishes, custom cabinetry, or complex roof lines will also push the budget higher compared to a standard design. Prefabricated units often offer predictable costs, while custom site-built structures allow for more flexibility but can be harder to estimate upfront. Exact pricing confirmed free on the call.
About this service
A modular ADU is a home built in a controlled factory setting and then transported to your property to be placed on a permanent foundation. This method is often faster than traditional stick-built construction because the structure is built off-site while your foundation is prepared. You should choose this if you want a quicker build timeline and less disruption to your backyard. Factors like site accessibility for cranes impact the final price. Exact pricing confirmed free on the call.
