The Short Answer
A full bathroom remodel in Dickinson requires a permit if you relocate any plumbing fixtures, add new electrical circuits, install a new exhaust fan, convert a tub to shower, or move walls. Surface-only work — tile, vanity, or faucet swap in place — does not need a permit.
Dickinson's Building Department enforces the 2015 International Building Code (which Texas adopted) and applies it strictly to interior bathroom work. The critical city-level detail: Dickinson sits in Galveston County, which falls in the 2A coastal wind zone; this matters because bathroom exhaust ducts and any exterior penetrations must meet higher wind-resistance standards (IRC R905.2.8 for ducts, ties to coastal design pressures). Additionally, Galveston County's expansive-clay soil (common to the Houston region) rarely affects bathroom remodels directly, but if your project involves ANY structural wall removal, the inspector will flag this early because foundations in Dickinson are prone to differential settlement — meaning the code enforcer becomes more stringent about load paths. Dickinson's online permit portal allows e-filing for most bathroom permits, cutting the typical Texas county back-and-forth time by 1–2 weeks. Plan-review timelines run 10–15 business days for a standard full remodel; expedited review (3–5 days) costs an extra $150–$250. The city's 2024 fee schedule bases bathroom-permit costs on project valuation (typically 1.5–2% of estimated construction cost), not a flat rate — meaning a $25,000 remodel budgets $375–$500 in permit fees alone.

What happens if you skip the permit (and you needed one)

Dickinson bathroom remodel permits — the key details

Dickinson follows the 2015 International Building Code (IBC) as adopted by Texas. The single most important rule for bathroom remodels is IRC P2706 (drainage and trap requirements) and IRC M1505 (exhaust ventilation). If you are relocating a toilet, sink, or tub, you must pull a plumbing permit. The drain trap arm — the horizontal run of pipe between the fixture and the main vent stack — cannot exceed 6 feet in length without an auxiliary vent (IRC P3105). This rule trips up many DIYers and contractors who assume they can run a drain 10 feet across the bathroom. Dickinson's inspectors are familiar with this and will reject rough plumbing if the trap arm is too long. The second critical rule is GFCI protection: all bathroom receptacles within 6 feet of a sink (measured horizontally along the floor) must be on a GFCI circuit, and the bathroom itself must have at least one GFCI outlet (IRC E3902.16 / NEC Article 210). If you are adding a new exhaust fan or replacing the existing one, you must show on the electrical plan that it vents to the exterior, not into the attic (IRC M1505.2 — a common violation that leads to mold and moisture damage in Dickinson's humid coastal climate). The minimum CFM (cubic feet per minute) for a bathroom exhaust fan is 50 CFM plus 1 CFM per square foot of bathroom area (IRC M1505.4); a 75-square-foot bathroom needs at least 125 CFM. Dickinson's inspectors will verify duct sizing and termination.

If you are converting a tub to a shower or vice versa, IRC R702.4.2 mandates a waterproofing assembly behind all wet areas. This is non-negotiable and a leading cause of permit rejections. The code accepts several systems: cement board with waterproof membrane (the most common), schluter pan systems, or pre-fabricated waterproof panels. You must specify which system on your permit application and submit a detail drawing showing the assembly. Many homeowners and contractors assume they can just tile over drywall; this violates code and invites future water damage. Dickinson's humid, salty air (coastal zone effects) makes waterproofing even more critical — inspector scrutiny is high. Similarly, if you are moving a shower valve (mixing valve), it must be pressure-balanced or thermostatic per IRC P2708 to prevent scalding; a standard non-balanced valve fails inspection. The valve type must appear on your plumbing plan. If your remodel includes any wall relocation or removal — even a partial-height wall separating the toilet area from the vanity — you must submit a structural drawing and pull a separate structural permit. Dickinson has not historically waived structural review for interior bathroom walls, so budget 2–3 extra weeks and $200–$400 for structural plan review.

Dickinson's online permit portal (accessed via the City of Dickinson website) allows you to e-file most bathroom permits. You will need a PDF of your floor plan showing existing and proposed fixture locations, electrical plan showing GFCI circuits and exhaust fan location, and a cost estimate (for fee calculation). For permits pulled before construction starts, the city processes applications in 10–15 business days; you can pick up the approved permit and begin work. For projects with structural changes or if the city's plan reviewer has questions, expect 15–21 days plus a 3–5 day revision cycle. Dickinson does NOT offer same-day or next-day plan review for bathroom remodels; if you need faster turnaround, the city charges an expedited-review fee (typically $150–$250 for 3–5 day review). The city requires that all work be inspected before it is covered — meaning you cannot insulate walls or install drywall until the rough plumbing and electrical have passed rough inspection. Typical inspection sequence: rough plumbing (traps, vents, main lines in place), rough electrical (circuits, breaker, GFCI breaker or outlets installed), framing/wall relocation (if applicable), drywall/waterproofing (before tile), and final (all fixtures set, exhaust fan operational, GFCI tested). Each inspection must be scheduled 24 hours in advance; inspectors usually arrive within 2–3 business days of scheduling.

Dickinson does permit owner-builder work on owner-occupied single-family homes. If you are the owner and will do the work yourself (or hire unlicensed labor under your supervision), you can pull the permit in your own name without a contractor's license. However, certain trades may require a licensed professional: plumbing (in most of Texas, including Galveston County) and electrical (NEC Article 90 compliance is strictly enforced in Dickinson) are regulated. You can run the project as the owner but must hire a licensed plumber and licensed electrician for those portions. Dickinson's Building Department will ask to see contractor licenses at permit issuance; make sure your plumber and electrician are registered with the City of Dickinson or hold valid state licenses. Many contractors from outside the city (Houston, Pearland) are acceptable as long as they carry the proper credentials.

Fees for a full bathroom remodel in Dickinson are calculated on the project's estimated construction cost. The city's 2024 fee schedule applies a base fee plus a percentage: typically $100–$150 base, plus 1.5–2% of estimated construction value for residential projects. A $25,000 remodel (materials + labor estimate) costs roughly $375–$500 in permit fees; a $40,000 remodel costs $700–$950. Plumbing and electrical permits are separate line items but often bundled in the bathroom-remodel fee if you file a single 'Bathroom Remodel' permit application. Dickinson does not charge re-inspection fees if work fails and must be corrected, but delays add to your calendar. Once you have a permit, work must begin within 180 days or the permit expires; if you exceed 180 days without substantial progress, the city may require a renewal application (an additional 50% of the original permit fee). Most bathroom remodels complete in 6–10 weeks, so expiration is rarely an issue, but budget-aware homeowners should note the deadline.

Three Dickinson bathroom remodel (full) scenarios

Scenario A
Vanity, toilet, and faucet swap in-place — coastal-zone home near Dickinson Bay
You are replacing an aging vanity, toilet, and faucet in a 1990s home 0.5 miles from Dickinson Bay (coastal 2A wind zone). The fixtures remain in their existing locations; no drain lines are extended, no new vent stack is added, no walls are touched. This is a surface-only renovation. Because no fixture is relocated and no electrical circuits are added (the existing outlet remains), Dickinson does not require a permit. You can purchase the new vanity, toilet, and faucet from a big-box store and install them yourself or hire a handyperson. No inspection is needed. However, since your home is within the coastal wind zone, if you are replacing the vanity cabinets and notice any rot or water damage in the framing behind the existing plumbing, address it before closing up the walls — Dickinson inspectors may order remediation if they discover code violations during later inspections (even for non-permitted work, if an inspector sees a clear hazard). Cost: vanity $400–$800, toilet $200–$400, faucet $150–$300; installation labor $300–$600 if you hire a plumber. Total: $1,050–$2,100. No permit fees.
No permit required (fixtures remain in-place) | Coastal zone wind rating does not trigger permit (no structural changes) | Licensed plumber recommended but not required | Total project cost $1,050–$2,100 | No permit fees
Scenario B
Relocate toilet and vanity to opposite wall, new exhaust duct, full shower conversion — central Dickinson house
You are gutting a 70-square-foot master bathroom in a 2005 house in central Dickinson (Galveston County 2A but inland from coastal wind zone). The toilet moves 8 feet from one wall to an adjacent wall; the vanity shifts 6 feet; the existing tub is being converted to a walk-in shower with a new waterproof pan system (schluter); a new exhaust fan with ducting is being installed to replace a non-functional unit. This requires a plumbing permit (fixture relocation), electrical permit (exhaust fan circuit, GFCI protection), and possibly a structural permit if you are removing the wall between the toilet and vanity (even a partial wall). The drain trap arm from the relocated toilet will run approximately 5 feet to the vent stack — within code. You submit a floor plan showing existing and new fixture locations, an electrical one-line diagram showing the exhaust fan circuit and GFCI receptacles, and a detail drawing of the shower waterproofing system (cement board + redguard membrane, or schluter pan). Dickinson's plan review takes 12–15 business days. Once approved, you schedule rough plumbing inspection (traps and vents set), rough electrical (circuits and exhaust fan wired), and a waterproofing inspection before tiling. Total project cost: $12,000–$18,000 (labor + materials). Permit fees: estimated $200–$350 (1.5–2% of $15,000 midpoint valuation). Timeline: 2–3 weeks for plan review, then 4–6 weeks for construction and inspections. If the plan reviewer questions trap-arm length or waterproofing system, add 5–7 days for revisions.
Permit required (fixture relocation + exhaust fan + shower conversion) | Trap arm within code (5 ft < 6 ft limit) | Waterproofing system must be specified (schluter/cement board/membrane) | GFCI protection on all receptacles within 6 ft of sink | Exhaust fan CFM: 50 + 1 per sq ft = 120 CFM minimum | Licensed plumber and electrician required | Total project cost $12,000–$18,000 | Permit fees $200–$350 | Plan review 12–15 days
Scenario C
Relocate toilet to new location, remove partition wall, no fixture moves beyond, owner-builder in west-Dickinson farmstead
You own a 1970s single-wide manufactured home on acreage west of central Dickinson (transitional area between Galveston County clay and west-Texas caliche soils). You are relocating the toilet from the back corner to a new location near the entry, which requires removing a partial load-bearing wall that separates the toilet room from the hallway. The vanity and shower remain in place (no fixture relocation there, just plumbing drain extension). Because you are an owner-occupant, you can pull the permit as an owner-builder; however, the partial wall removal triggers a structural permit requirement. Dickinson will not issue a plumbing permit until structural approval is in hand. You must hire a licensed structural engineer or have the city's building official review the wall and sign off (cost: $300–$600 engineer, or $0–$150 if the official does a simple visual review). The toilet relocation adds 10 feet of new drain run; the inspector will verify trap-arm length and vent-stack connection. You also must have a licensed plumber and electrician do the work (or at minimum, hire a licensed plumber for the drain extension and tie-in). Plan review: structural 10–12 days, plumbing 12–15 days (sequential, not parallel, because structural must clear first). Inspections: structural framing, rough plumbing, final plumbing. Total project cost: $8,000–$12,000. Permit fees: structural $100–$200, plumbing $150–$250. Timeline: 3–4 weeks for plan review, 3–4 weeks for construction.
Permit required (wall removal + fixture relocation) | Structural engineer or city review required for wall removal | Trap-arm length verified (max 6 ft without auxiliary vent) | Licensed plumber required (drain extension) | Owner-builder allowed for owner-occupied | Sequential plan review (structural first) | Total project cost $8,000–$12,000 | Permit fees structural + plumbing $250–$450 | Timeline 6–8 weeks (review + construction)

Dickinson's coastal-zone exhaust-fan and duct requirements

Dickinson sits in a coastal wind zone (2A per ASCE 7 / IBC Figure 1604.3). While most bathroom exhaust-fan rules are identical to inland Texas code, the coastal zone adds one critical requirement: exhaust ducts must resist uplift and wind loading. IRC M1505.2 mandates that ducts terminate to the exterior, not into the attic. Dickinson's inspectors verify that the duct is securely fastened (not just loose-laid across rafters) and that the exterior termination includes a proper damper and escutcheon (flashing) rated for coastal wind. Most standard bathroom fans and ducts meet this; the issue arises when a contractor runs flexible duct without proper support or terminates into a soffit that faces the prevailing wind. Plan on $150–$300 for a proper coastal-compliant exhaust installation (duct, damper, flashing).

The minimum CFM for a bathroom exhaust fan in Dickinson is 50 CFM plus 1 CFM per square foot of bathroom floor area (IRC M1505.4). A typical 75-square-foot master bath requires at least 125 CFM. Many homeowners buy undersized fans (50 or 80 CFM) thinking they will save money; Dickinson's inspector will calculate CFM requirements on your plan and flag undersized equipment. If you are replacing an existing fan with a retrofit model, verify the CFM rating before purchase. Quiet, high-efficiency fans (Panasonic WhisperFit, Broan Sensonic) run $200–$350 and meet all Dickinson coastal-zone and IRC requirements.

If your remodel involves adding a second bathroom or upgrading an attic space to include a new bathroom, each bathroom must have its own dedicated exhaust fan or a shared system with manual dampers per bathroom and adequate CFM. Dickinson does not allow a single fan to serve two bathrooms unless the ducts are independent and each dampers separately. This is important for homes being converted from 1-bath to 2-bath or in accessory-dwelling-unit scenarios.

Waterproofing a shower or tub conversion in Dickinson's humid climate

Dickinson's coastal 2A climate (humidity 70–85% year-round, salt spray within 2 miles of the bay) makes waterproofing non-negotiable. IRC R702.4.2 requires all surfaces behind a bathtub or shower to be waterproofed. The code accepts three main systems: (1) cement board plus waterproof membrane (redguard, Kerdi, Ditra), (2) Schlüter pan (pre-formed, self-contained), or (3) pre-fabricated fiberglass/acrylic panels. Dickinson inspectors will want to see the system specified on your permit application. Many DIYers assume they can tile over greenboard or regular drywall; this fails inspection and will cause mold and structural damage within 2–5 years in Dickinson's climate. Cost: cement board + membrane system $400–$700, Schlüter pan $800–$1,200, prefab panels $600–$1,000. Schlüter systems are becoming the standard in Dickinson because they are foolproof and approved by all inspectors.

If you are tiling a shower wall in a remodel, the substrate behind tile must be at least 1/4-inch cement board attached to studs with corrosion-resistant fasteners (no nails). Regular drywall will absorb moisture, swell, and fail in Dickinson's humid environment. Tile itself is permeable; moisture passes through grout and can sit behind tile if there is no waterproof membrane. The membrane is the critical layer — it directs water down to a drain pan at the bottom, preventing saturation of the framing. Dickinson inspectors will ask to see membrane installation photos before you close up the wall with drywall or tile.

For tub-to-shower conversions, Dickinson requires a curb or threshold if the shower floor is lower than the bathroom floor (to contain spray water). If you are building a curbless shower (zero-threshold), you must slope the shower floor 1/8 inch per foot toward a linear drain, and the waterproofing system must be top-tier (Schlüter, schluter linear drain kit, etc.). Curbless showers cost $2,000–$4,000 installed in Dickinson because they demand precision in waterproofing and drainage. Standard curbed showers cost $1,200–$2,500.

Common questions

Do I need a permit to replace a toilet in the same location?

No. Replacing a toilet in its existing location does not require a permit in Dickinson. You can remove the old toilet and install a new one without calling the city. However, if you are moving the toilet to a different location (even a few feet away), you must pull a plumbing permit because the drain line and vent connection change. Make sure any new toilet is ADA-compliant height (15–19 inches seat height) if local code has accessibility requirements; most modern toilets are standard height and acceptable.

What is the cost of a bathroom remodel permit in Dickinson?

Permit fees are typically $200–$500 for a full bathroom remodel in Dickinson, calculated as 1.5–2% of the estimated project cost. A $25,000 remodel costs roughly $375–$500 in permit fees; a $15,000 remodel costs $225–$300. Fees are non-refundable. You must provide a cost estimate when you apply; the city uses this to calculate the fee. If the inspector later determines the project scope increased, you may owe an additional fee (usually 50% of the original).

Do I need a licensed contractor to do a bathroom remodel in Dickinson?

If you are the owner and the home is owner-occupied, you can pull the permit as an owner-builder and do much of the work yourself. However, plumbing and electrical work are regulated by the state and by Dickinson. You must hire a licensed plumber for any drain relocation, new water supply lines, or trap/vent work. You must hire a licensed electrician for any new circuits, GFCI upgrades, or exhaust fan installation. General carpentry, tile, drywall, painting, and fixture installation can be done by you or a general contractor. Make sure any licensed professional you hire is registered with Dickinson or holds a valid state license.

How long does plan review take for a bathroom remodel in Dickinson?

Standard plan review takes 10–15 business days. If the reviewer has questions or asks for revisions (e.g., clarifying waterproofing system, GFCI placement, or exhaust-fan CFM), add 5–7 days for resubmission and re-review. If your project includes a wall removal or structural change, add 10–12 days for structural review, which must clear before plumbing review starts. Expedited review (3–5 days) is available for an extra $150–$250 fee.

What inspections are required for a bathroom remodel permit in Dickinson?

Typical inspections are: (1) rough plumbing (traps, vents, main drains), (2) rough electrical (circuits, breaker, GFCI outlets), (3) framing/wall removal (if applicable), (4) waterproofing (before tile or drywall closes), and (5) final (all fixtures set, exhaust fan operational, GFCI tested). You must schedule each inspection 24 hours in advance. Inspectors usually respond within 2–3 business days. If any inspection fails, you correct the issue and reschedule at no additional fee; delays are rare unless the inspector finds code violations that require structural work.

Can I start my bathroom remodel before receiving the permit?

No. Dickinson requires permits to be approved and in hand before work begins. Starting before the permit is issued violates city ordinance and can result in a $500–$1,500 stop-work order fine. If you have already started, stop, contact the building department immediately, and pull a permit. The city may issue a violation notice requiring you to restore the bathroom or complete the work under inspection. It is always cheaper and faster to get the permit first.

What is the 'frost depth' rule for Dickinson bathrooms?

Frost depth (the depth to which the ground freezes in winter) affects exterior plumbing lines but rarely impacts interior bathroom remodels in Dickinson. Galveston County's frost depth is 6–12 inches (inland) to 0 inches (coast), depending on location. Interior bathroom drains, supply lines, and vents are not affected because they run through the home's heated interior. If your remodel includes a new exterior water faucet or drain for a wet room, frost depth rules apply; consult the inspector.

Do I need to disclose unpermitted bathroom work when I sell my house in Dickinson?

Yes. Texas Property Code § 5.006(b) requires sellers to disclose all known non-permitted work on the Property Condition Addendum (TPA). If you completed a bathroom remodel without a permit, you must disclose it. Buyers and their lenders will often demand that permits be pulled retroactively (at 1.5–2× the original fee) or that the work be removed. Non-disclosure can result in a lawsuit or loan-denial. It is always safer and cheaper to get the permit upfront.

What happens if my contractor doesn't pull a permit for my bathroom remodel?

You are liable. Even if a contractor promised to handle permits and failed to do so, the homeowner bears responsibility. The city can issue a violation notice to you (not the contractor), fine you $500–$2,000, and require the work to be corrected or removed. You can pursue the contractor for reimbursement, but this often requires a lawsuit. Always verify that a permit has been issued and inspect the permit card before allowing the contractor to begin work. Ask to see the permit and approval letter on the first day of work.

Is there a difference between a bathroom remodel permit and a 'bathroom renovation' permit in Dickinson?

Dickinson uses the term 'Bathroom Remodel' for most renovations. Some jurisdictions distinguish 'remodel' (existing fixtures) from 'renovation' (gut renovation with wall changes); Dickinson does not formally separate these. Pull a 'Residential Interior Remodel' or 'Bathroom Remodel' permit regardless. If walls are being moved or structural changes are involved, note this on the permit application so the city flags it for structural review from the start. This ensures you are not delayed mid-project.
