Do I Need a Permit for a Bathroom Remodel in Montgomery, AL?
Montgomery handles bathroom remodel permits through its Inspections Department, which issues separate building, plumbing, electrical, and mechanical permits — each with its own application through the city's Online Permitting Portal. The key distinction between what requires a permit and what doesn't in Montgomery mirrors Alabama's statewide framework: system changes need permits; cosmetic improvements do not.
Montgomery bathroom remodel permit rules — the basics
The City of Montgomery's Inspections Department handles all residential permit types: building, electrical, plumbing, gas, and mechanical. The permit applications are submitted through the city's Online Permitting Portal, accessible at montgomeryal.gov. The Inspections Department also accepts appointments for in-person assistance — call 334-625-2073 to schedule. Trade permits (plumbing, gas, mechanical) follow the requirements outlined on the city's Plumbing, Gas and Mechanical Inspections page, which specifies the contractor credentialing requirements: current state certification (Alabama plumbing, heating/AC, or gas board credentials), a copy of the current City of Montgomery business license, a copy of the master card holder's state certification card, and a permit application signed by the master card holder listed on the business license.
The framework for when a permit is required follows the system-modification standard: work that changes or extends plumbing, electrical, or structural systems in the bathroom requires the corresponding permit. Purely cosmetic work — retiling, repainting, replacing a vanity in the same location with the same drain and supply connections, swapping a light fixture in the same junction box without adding wiring — doesn't alter any system and doesn't require a permit. The moment a project relocates a fixture to a new position, extends or adds electrical circuits, removes walls, or modifies the structural framing, the applicable permit or permits are required.
For full bathroom remodels in Montgomery's older housing stock — the city has significant residential construction from the 1940s through 1970s in neighborhoods like Cloverdale, Capital Heights, and Forest Hills — the hidden condition risks familiar from Birmingham apply here too: aging cast-iron drain lines, galvanized supply pipes, and undersized electrical service panels are common discoveries once walls are opened during a remodel. Licensed Montgomery contractors who regularly work in these neighborhoods are the most reliable source of realistic project budgeting that accounts for these possibilities.
The owner-builder exemption applies to bathroom remodels as it does to other residential projects in Montgomery: the homeowner must have occupied the home for at least one year from CO issuance and must sign the affidavit. However, the Inspection & Permit FAQ is explicit that if the owner-builder hires someone else to do plumbing or HVAC work, those contractors must be Alabama-licensed and hold a valid City of Montgomery license. This means the most common bathroom remodel scenario — a homeowner hiring a plumber and an electrician as sub-contractors while managing the project — requires those trades to pull their own permits under their Alabama state licenses and Montgomery city business licenses.

Montgomery's trade licensing requirements for bathroom remodel contractors
The City of Montgomery's Plumbing, Gas and Mechanical Inspections page lays out specific contractor requirements for trade permits. For plumbing permits, the contractor must provide: current certification from the State of Alabama (the Alabama Board of Plumbing Examiners), a copy of the current City of Montgomery Business license on file in the Permitting Department, a copy of the master card holder's state certification card on file in the Permitting Department, a color copy of the master card holder's driver's license or state-issued photo ID on file, and a permit application signed by the master card holder listed on the business license. The mechanical (HVAC) permit requirements are similar: current certification from the State of Alabama Board of Heating and Air Conditioning Contractors, plus city business license, master card, and ID documentation.
This documentation-forward approach means that trade contractors working in Montgomery must have their city business license and state certification on file with the Permitting Department before they can pull permits. Homeowners hiring plumbers and electricians for a bathroom remodel should confirm that their contractor has current Alabama state credentials and a valid City of Montgomery business license — not as a bureaucratic formality, but because unpermitted trade work in Montgomery creates the same property-attaching liability risk as in Birmingham: if the work is later found to violate code, the cost of correction and the permitting penalty are the property's responsibility.
For bathroom remodels that involve gas work — a natural gas tankless water heater in a new location, a gas line to a fireplace in an adjacent space — a gas permit is required in addition to the plumbing permit. Gas work in Montgomery requires the same contractor credentialing as mechanical work: state certification and city business license. Given Montgomery's climate — adequate without gas heating most of the year — gas installations in bathrooms are less common than in northern markets, but gas tankless water heaters and gas fireplaces in expanded master suites are a growing trend in Montgomery's luxury renovation market.
What the inspector checks in Montgomery
Montgomery trade inspections for bathroom remodels follow the standard rough-in-before-closing and final-after-completion sequence. Plumbing rough-in checks drain slopes (minimum 1/4 inch per foot horizontal), proper venting connections, trap installation and distances from vents, and supply line sizing. Electrical rough-in checks wire gauges, GFCI protection for all bathroom outlets (required under Alabama's adopted electrical code), box fill, and conduit work. For structural work — wall removal or new framing — a framing inspection confirms proper header installation, structural continuity, and rough-in accessibility. Final inspections confirm all fixtures are installed and functional, GFCI outlets test correctly, exhaust fan operates and is ducted to the exterior, and the completed work matches the permit scope.
Inspections are scheduled through the Inspections Department at 334-625-2073. Montgomery's Plumbing, Gas & Mechanical Inspections page notes that inspections require appointments, and the Inspections Department page notes that all required approvals should be verified before appointments. The Residential Inspections Checklist (available at montgomeryal.gov) outlines the specific items checked at each stage.
What a bathroom remodel costs in Montgomery
Bathroom remodel costs in Montgomery are among the more affordable in Alabama. A mid-range hall bathroom update runs $7,000–$15,000. A full master bathroom gut with walk-in shower and new finishes runs $18,000–$38,000. Luxury master bath renovations in Montgomery's higher-end neighborhoods (Hampstead, Taylor Road area, Pike Road) run $40,000–$70,000. Labor costs in Montgomery's market are noticeably lower than Birmingham; tile installers run $7–$12 per square foot installed; licensed plumbers $75–$110 per hour; electricians $70–$105 per hour. Permit fees (confirmed at 334-625-2073) are a small fraction of any project cost.
What happens if you skip the permit
Unpermitted plumbing and electrical work in Montgomery carries the same risks as in other Alabama jurisdictions: potential insurance claim denials for water or fire damage traceable to uninspected work, complications at home sale when permit records don't match visible renovation scope, and the cost of retroactive permitting that may require wall access for rough-in inspections of completed work. Montgomery's 311 complaint system provides a mechanism for neighbors and buyers to report suspected unpermitted construction. The Inspections Department investigates and notifies property owners of violations. For a bathroom remodel that involved plumbing and electrical changes, a retroactive permit requires the same rough-in inspections as a prospective permit — meaning finished tile work may need to be disturbed to expose the plumbing and electrical rough-in for inspection.

Common questions
Does replacing a toilet require a permit in Montgomery?
Replacing an existing toilet with a new toilet in the same location — same drain flange, same supply connection, no piping changes — does not require a plumbing permit in Montgomery. Like-for-like fixture replacement in the same rough-in position is maintenance, not a plumbing system change. The permit obligation arises when any plumbing line is moved, extended, or newly run. A toilet relocation to a new position (even a few inches) requires extending or modifying the drain and supply, triggering a plumbing permit. Confirm specific scope questions with the Inspections Department at 334-625-2073.
What contractor licenses are required for plumbing work in Montgomery?
Under the City of Montgomery's requirements, plumbing contractors must provide: current Alabama state plumbing certification, a City of Montgomery business license, the master plumber's state certification card on file, and a color copy of the master card holder's ID. All must be on file in the Permitting Department. The permit application must be signed by the master card holder listed on the business license. These requirements apply to any plumbing permit in Montgomery city limits — there is no minimum project size below which these credentialing requirements are waived. Contact the Inspections Department at 334-625-2073 to confirm that a specific contractor's credentials are current before the contractor pulls a permit for your project.
Does Montgomery require GFCI protection in bathrooms?
Yes. Alabama's adopted electrical code (following the NEC framework) requires GFCI protection for all receptacles in bathroom spaces. Any new electrical circuit or outlet added to a Montgomery bathroom during a permitted remodel must include GFCI protection. Electrical inspectors check GFCI compliance during rough-in and final inspections. For older Montgomery homes being remodeled — particularly pre-1980 construction that may have non-GFCI bathroom outlets — any new electrical work within the permitted scope must meet current code requirements. The inspectors won't require retroactive upgrading of unmodified existing circuits that are outside the permit scope, but all new work must comply with current standards.
Can a homeowner pull their own plumbing permit in Montgomery?
A homeowner can pull their own plumbing permit for their owner-occupied primary residence under the owner-builder exemption, which requires occupying the home for at least one year from CO issuance and signing the occupancy affidavit. However, the Montgomery Inspection & Permit FAQ notes that if the owner-builder hires someone else to do the plumbing work, that person must be an Alabama-licensed contractor with a valid City of Montgomery license. This means the homeowner exemption covers only work the homeowner personally performs — hiring a plumber to do the actual work requires that plumber to pull their own permit under their credentials, not the homeowner's exemption. Gas pipe installations are explicitly excluded from the owner-builder exemption entirely.
How long does a Montgomery bathroom remodel permit take to process?
Montgomery processes residential trade permits (plumbing, electrical, mechanical) through its Online Permitting Portal. Processing time for complete applications is not specifically published but is generally consistent with comparable Alabama cities at 5–12 business days. The Inspections Department page notes that appointments are required for in-person service and that all required forms and approvals should be completed before arriving. For the fastest processing, submit complete applications online through the portal at the outset rather than in incremental stages, and ensure contractor credentials (state licenses and city business licenses) are current and on file before the permit application is submitted. Contact 334-625-2073 for current processing time estimates.
What happens if a Montgomery contractor does bathroom work without a permit?
A contractor who performs bathroom plumbing, electrical, or structural work in Montgomery without pulling the required permit is subject to code enforcement and liability consequences. The Montgomery FAQ notes that permits are required for any construction work on a building's mechanical, electrical, or plumbing systems. For the homeowner, the risk is property-level: unpermitted work can complicate home sales (buyer inspectors cross-reference permit records), create insurance claim exposure for water or fire damage from uninspected work, and require costly retroactive permitting with wall access for rough-in inspection. The homeowner's best protection is to confirm before work begins that the contractor has pulled the required permit — the permit card should be available on site before any permitted work starts.
