Metairie Terrace, Louisiana homeowners considering an accessory dwelling unit (ADU) must follow Jefferson Parish land-use and building rules that govern permitting, inspections, and occupancy. This guide explains where to start, which office enforces ADU requirements, typical permit steps, common compliance pitfalls, and how to appeal or request variances.

Overview

Accessory dwelling units (ADUs) — also called secondary units, granny flats, or in-law suites — are regulated through the Jefferson Parish unified land-use and building system. Zoning, lot coverage, parking, and building-code requirements determine whether an ADU is allowed and what approvals are needed. For the controlling ordinance and zoning criteria, consult the parish planning code and unified development rules [1].

Start early: preliminary meetings with planning staff reduce delay.

Penalties & Enforcement

Enforcement is handled by Jefferson Parish code enforcement and building inspection divisions; administrative orders, stop-work notices, and civil fines are typical enforcement tools. Specific fine amounts, escalation schedules, and daily continuing penalties are not specified on the cited page [3]. Where numeric fines or precise escalation schedules exist they appear in the parish code or the enforcement division's published schedules.

  • Monetary fines: not specified on the cited page.
  • Non-monetary orders: stop-work orders, mandatory correction notices, and demolition/abatement orders may be issued.
  • Complaint pathway: submit complaints or request inspections via the parish code enforcement/contact portal [3].
  • Escalation: first and repeat offences handling is not specified on the cited page; contact enforcement for precise schedules.
Unpermitted occupancy can trigger abatement and civil penalties.

Applications & Forms

Typical submissions for an ADU include a zoning permit or variance application, a building permit with construction drawings, and trade permits for electrical, plumbing, and mechanical work. The official building permit application and instructions are available from the parish permits and licensing office [2]. If a specific parish ADU checklist is not published, provide full site and elevation plans with your permit submittal.
