Housing and Building Standards Alabama 3 Minutes Read ยท published February 10, 2026 Flag of Alabama

Montgomery, Alabama property owners considering an accessory dwelling unit (ADU) must follow local zoning and building-permit processes before construction or rental. This guide explains typical steps for ADU permits, what departments enforce rules in Montgomery, and practical actions to apply, pay fees, arrange inspections, and appeal decisions.

Overview of ADU permit process

ADUs may be regulated under zoning, building, and property-use provisions. Start by confirming zoning allowances, required setbacks, parking requirements, and whether an owner-occupancy condition or size limit applies. Consult Planning and Building departments early to avoid costly revisions.

Penalties & Enforcement

Enforcement of ADU-related violations in Montgomery is handled by municipal planning, building inspections, and code compliance units. Specific monetary fines, escalation amounts, and continuing offence rates are not specified on the cited pages below; consult the city code or enforcement office for exact penalty schedules.[1] For building-safety or unsafe-structure issues, the Building Inspections office may issue stop-work orders and require corrective action; the timeline for compliance and appeal rights are set by ordinance and department rules.[2]

  • Enforcer: Planning & Development and Building Inspections departments handle zoning and permit compliance.
  • Fines: not specified on the cited page.
  • Escalation: first/repeat/continuing offence ranges not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, demolition or abatement orders, revocation of permits, and court actions are possible.
  • Inspection/complaint: submit complaints or request inspections via the Building Inspections office contact page.[2]
  • Appeals: appeal routes and time limits are set by ordinance or departmental rules; if not shown on the department page, the city code controls (time limits may be specified in the ordinance).

Applications & Forms

Typical applications include a zoning verification or special-use permit (if required), a building permit application, and plan review submittals. The city publishes permit application procedures on the Building Inspections page, but specific form numbers and fee tables are not fully listed on that page; obtain current application PDFs from the department or permit counter.[2]

Always request a pre-submittal meeting with Planning and Building staff before preparing final plans.
  • Common forms: Building permit application (plan review), zoning verification or conditional-use application; consult the Building Inspections and Planning pages for files.
  • Fees: permit and plan-review fees vary by scope; fee schedules are not fully specified on the cited department pages.
  • Deadlines: submission processing times depend on completeness and staff workload; ask the permit counter for typical review timelines.

Action steps

  • Confirm zoning allowance and any special-use requirement with Planning; request zoning verification.
  • Prepare construction drawings meeting the International Residential Code and local amendments; include life-safety systems if required.
  • Submit building permit application with plans, site plan, and required attachments to Building Inspections.
  • Pay plan-review and permit fees when invoiced; confirm refund/transfer policies before paying non-refundable fees.
  • Schedule inspections during construction and obtain final occupancy sign-off before renting or inhabiting the ADU.
