Do I Need a Permit for a Bathroom Remodel in Birmingham, AL?
Birmingham's permitting rules are sweeping for residential work: only painting and like-for-like roof shingle replacement are exempt. That means any bathroom remodel involving plumbing changes, electrical work, or structural modifications triggers at minimum one permit — and a full gut renovation typically triggers three separate permits, each with its own application, fee, and inspection sequence.
Birmingham bathroom remodel permit rules — the basics
The City of Birmingham's Department of Planning, Engineering & Permits (PEP) governs bathroom remodel permits under the 2024 Technical Code (Ordinance 15-164, effective October 1, 2024), which adopts the International Residential Code and companion codes as the city's Technical Code. The familiar framework applies: cosmetic work that doesn't alter the plumbing, electrical, or structural systems requires no permit; any system change triggers the applicable permit or permits. Birmingham's fee schedule is consistent across all permit types: $9.50 per $1,000 of the applicable trade valuation, with a minimum of $120 for building permits and $125 for all trade permits (plumbing, electrical, mechanical, gas).
One important Birmingham-specific procedural requirement: if any plumbing is being added or changed as part of the remodel, the PEP cannot issue the building permit until the applicant provides a copy of a sewer impact permit from Jefferson County Environmental Services. This is not a trivial bureaucratic step — the sewer impact permit documents that the additional plumbing connections are compatible with the sewer system's capacity. It must be obtained from Jefferson County separately and presented to PEP as part of the building permit application. For bathroom remodels that add a new fixture (a second sink, a shower where none existed), this step is required. For like-for-like fixture replacements in the same location, the sewer impact permit is not required.
Alabama state law requires that any residential project valued at $10,000 or more must be performed by a contractor holding an Alabama Home Builders license, unless the homeowner is doing the work themselves. For a bathroom remodel valued at $15,000–$35,000 — which covers most mid-range and full gut renovations in Birmingham — this means the general contractor must hold the state Home Builders license, and their license number must appear on the building permit application. Trade contractors (plumbers, electricians, HVAC technicians) must also hold their respective Alabama state trade licenses. The penalty for commencing work without a permit in Birmingham is a doubling of the required permit fee — and this doubled fee penalty attaches to the property, not just the contractor.
Applications for all trade permits (electrical, plumbing, gas, mechanical) in Birmingham can be submitted through the Online Permit Center at birminghamal.gov/work/building-permits-permit-inquiry. Building permit applications for residential remodels are submitted through the same ePermit Hub. Plans for single-family residential projects must be submitted as two sets (paper, 18 inches by 24 inches minimum, or PDF for the Digital Plan Room). The plans must include at minimum a floor plan showing existing and proposed fixture locations, a wall section showing the construction, and a site plan for the property. Same-day inspections are often available by calling 205-254-2211 between 7:30 and 8:30 a.m. Monday through Friday.

Birmingham's 2024 Technical Code — what changed for bathroom remodels
Birmingham adopted its 2024 Technical Code (Ordinance 15-164) effective October 1, 2024. This edition updates the city's building code baseline, aligning with more current IBC, IRC, and companion code editions. For bathroom remodels specifically, the updated code reflects improved moisture management requirements, updated GFCI protection provisions, and enhanced ventilation standards for bathroom spaces. Bathrooms without operable windows must have mechanical exhaust ventilation — a requirement that has been in the IRC for years but is now enforced under the updated Technical Code with inspectors specifically checking that the exhaust fan circuit is functional and that the fan is ducted to the exterior (not terminating in the attic, which is a code violation regardless of how common it is in older Birmingham homes).
The sewer impact permit requirement from Jefferson County Environmental Services is not new to the 2024 Technical Code but is frequently overlooked by homeowners and even by some contractors who are unfamiliar with Birmingham's specific permitting workflow. The Jefferson County sewer system serves Birmingham and its surrounding municipalities, and the impact permit ensures that new plumbing connections don't overload the system. For most bathroom remodels, the sewer impact permit is a relatively quick approval — Jefferson County Environmental Services typically processes them in 5–7 business days — but failing to start the process concurrently with the PEP permit application can add a week or more to the overall timeline.
Birmingham's older housing stock — particularly the Craftsman bungalows, Tudor revivals, and ranch homes that dominate the city's established neighborhoods — commonly presents hidden-condition surprises during bathroom remodels. Cast-iron drain lines in pre-1970 homes deteriorate from the inside out, and it's common for a plumber to discover that the drain stack beneath a bathroom being remodeled has significant corrosion or partial blockage. Galvanized steel supply lines in pre-1960 homes have similar longevity issues. Both are conditions that contractors often recommend addressing while the walls are open, adding $1,500–$4,000 to the plumbing permit valuation and fees but avoiding future emergency repairs in a finished bathroom.
What the inspector checks in Birmingham
Birmingham bathroom remodel inspections are scheduled by calling 205-254-2211 between 7:30 and 8:30 a.m. Monday through Friday, with same-day appointments often available. The inspection sequence for a permitted bathroom remodel varies with scope but typically includes: a rough-in plumbing inspection (after new drain and supply lines are installed but before walls are closed), a rough-in electrical inspection (after new wiring is in place but before drywall), and a final inspection after all work is complete and fixtures are installed. For projects with structural work (wall removal, new header installation), a framing inspection is added after structural framing is complete but before insulation or drywall is installed.
At the plumbing rough-in, the inspector verifies drain slopes (minimum 1/4 inch per foot of horizontal run), proper vent connections to the stack, trap installation for each fixture (no trap-to-trap distances exceeding code limits), and supply line sizing. At the electrical rough-in, the inspector checks wire gauges, box fill, GFCI protection for all outlets within 6 feet of a sink and all bathroom outlets generally, and the exhaust fan circuit. At the final inspection, the inspector verifies that all fixtures are installed and functional, that the exhaust fan is operating and ducted to the exterior, that GFCI outlets are testing correctly, and that the shower enclosure meets waterproofing requirements if a shower was installed or relocated. Reinspection fees apply if a scheduled inspection cannot be completed: the penalty is a doubling of the original permit fee for work started without a permit, and a standard reinspection fee for failed inspections.
What a bathroom remodel costs in Birmingham
Birmingham's bathroom remodel costs track below national averages, reflecting the city's lower labor market. A mid-range hall bathroom update — new tile, vanity, lighting, fixtures with minimal layout changes — runs $8,000–$18,000. A full master bathroom gut with walk-in shower, freestanding tub, and double vanity runs $25,000–$45,000. Labor accounts for 40–50% of typical project cost. Tile installers in Birmingham charge $8–$14 per square foot installed; licensed plumbers run $80–$120 per hour; electricians $75–$115 per hour. Permit fees ($375–$980 for a full renovation) represent less than 2% of project cost at the high end.
What happens if you skip the permit
Birmingham's penalty for commencing work before a permit is issued is a doubling of the required permit fee — and the ordinance specifies that this double-fee penalty attaches to the property itself, not just to the contractor. This means a homeowner who later sells the property with the unpermitted work outstanding may face a doubled fee demand as a condition of clearing the property record at closing. Retroactive permits for bathroom plumbing and electrical work require wall access for rough-in inspection — meaning finishes must be disturbed. Insurance claim denials for water damage from improperly installed plumbing, and for electrical fires from uninspected wiring, are real downstream risks that the permit fees protect against.

Common questions
Does replacing a toilet require a permit in Birmingham?
Replacing a toilet with a new toilet in the same location — same drain flange, same supply connection — does not require a plumbing permit in Birmingham. The exemption applies to like-for-like fixture replacement in the same position with no alteration to existing piping. Moving the toilet to any new position, even a few inches, requires extending or modifying the drain, which triggers a plumbing permit and a Jefferson County sewer impact permit. Homeowners replacing an old toilet as part of a cosmetic bathroom update can proceed without a permit; those incorporating the toilet relocation into a larger remodel must permit the plumbing work.
What is the Jefferson County sewer impact permit and when is it required?
The Jefferson County sewer impact permit is issued by Jefferson County Environmental Services and certifies that proposed new or additional plumbing connections are compatible with the sewer system's capacity at the relevant point of connection. In Birmingham, PEP cannot issue a building permit for any project that adds or modifies plumbing connections until the applicant provides a copy of the sewer impact permit. The permit is required any time a new plumbing fixture is being added (a second sink, a new shower, a relocated toilet), or when existing plumbing is being significantly modified. Like-for-like replacements that don't change the connection points don't require it. Contact Jefferson County Environmental Services at 205-325-8741 to initiate the sewer impact permit process concurrently with your PEP permit application.
Do trade contractors in Birmingham need licenses to do bathroom remodel work?
Yes. All trades working in Birmingham must hold appropriate Alabama state licenses. Plumbers must hold Alabama state plumbing licenses; electricians must hold Alabama state electrical licenses; HVAC contractors must hold mechanical contractor licenses. For any residential project valued at $10,000 or more, the general contractor overseeing the work must hold an Alabama Home Builders License and provide their license number on the building permit application. Homeowners who are performing their own work (not a licensed contractor) can pull their own permits by signing an owner-builder affidavit, but this applies only to work they personally perform at their primary residence — not to work done by unlicensed third parties on the homeowner's behalf.
How long does a Birmingham bathroom remodel permit take?
A complete application package for a residential bathroom remodel is typically processed in 7–14 business days at PEP. The Jefferson County sewer impact permit, if required, takes an additional 5–7 business days and should be initiated simultaneously with the PEP application to avoid adding to the overall timeline. Once permits are issued, same-day inspections are often available by calling 205-254-2211 before 8:30 a.m. Monday through Friday. Incomplete or inaccurate applications that require back-and-forth with plan reviewers are the most common cause of extended timelines — submitting complete plans with site plan, floor plan, and plumbing/electrical scope descriptions on the first submission minimizes review cycles.
Does Birmingham require GFCI protection in bathrooms?
Yes. Under Birmingham's adopted Technical Code (2024 edition, effective October 1, 2024), all receptacles in bathrooms must have GFCI protection. Any new bathroom circuit added during a remodel must be GFCI-protected. Exhaust fans with electrical connections must be on properly protected circuits. The electrical inspector specifically checks GFCI compliance during rough-in and final inspections for bathroom remodels. In older Birmingham homes being remodeled, the inspection process often reveals existing non-GFCI outlets in bathrooms — while the city doesn't require retroactive upgrade of outlets outside the permitted work scope, all new and modified circuits within the permit scope must meet current code.
Can I remodel my Birmingham bathroom myself without a contractor?
Yes, with conditions. A homeowner can pull their own building, plumbing, and electrical permits for their owner-occupied primary residence in Birmingham by signing an owner-builder affidavit affirming that no licensed building contractor is involved and that they will personally perform the work. This exemption is specifically for homeowners working on their own home — it cannot be used to cover unpermitted work by unlicensed tradespeople. Practically speaking, most bathroom remodels involving drain line relocation and new electrical circuits are technically demanding enough that most homeowners are better served by licensed contractors. The homeowner exemption is genuine and available; the question is whether the homeowner has the skills to produce work that will pass inspection.
