Intro

Memphis, Tennessee homeowners considering an accessory dwelling unit (ADU) need to follow city zoning and permitting rules before construction or rental. This guide explains where ADUs are allowed, how the local zoning and building-permit process works, what forms and inspections apply, and how enforcement and appeals operate in Memphis. It condenses official requirements, links to municipal sources, and gives clear action steps so homeowners can prepare applications, request inspections, and avoid common violations. For legal certainty, consult the cited municipal code and the City permit office during planning.[1]

Overview

An ADU is a secondary, independent dwelling on a lot with a primary residence. In Memphis, rules determine permitted zones, size limits, parking, and owner-occupancy conditions. Requirements vary by district and property type; review the local code and confirm with Planning staff before design.

Zoning basics for ADUs

Typical zoning topics to check:

  • Permitted zones and conditional-use rules for ADUs.
  • Maximum unit size relative to the primary dwelling or lot coverage.
  • Setbacks, height limits, and lot standards.
  • Parking and access requirements.
Check your zoning district before preparing plans.

Confirm specific zoning allowances and any required variances in the City of Memphis development code and consult Planning staff for site-specific interpretation.[1]

Design & building standards

ADUs must comply with building, life-safety, and utility standards enforced through the City's permit and inspection process. Common requirements include separate egress, fire separation, mechanical and plumbing compliance, and connection to approved utilities.

  • Inspections: footing/foundation, framing, plumbing, electrical, and final.
  • Permit fees and plan-review fees where applicable (see permit office).
  • Required plans: site plan, floor plan, elevations, and utility diagrams.
Submit complete construction plans to avoid review delays.

Penalties & Enforcement

Enforcement is handled by City of Memphis code and permit offices and may include fines, stop-work orders, and court actions. Where the municipal code specifies monetary penalties or escalation, review the cited code; if penalties or escalation amounts are not given on the cited page, the text below notes that.

  • Monetary fines: not specified on the cited page.[1]
  • Escalation (first/repeat/continuing offences): not specified on the cited page.[1]
