Maywood bathroom remodel permits — the key details

Maywood requires a permit for any bathroom project that involves moving fixtures, adding circuits, changing the tub/shower assembly, installing a new exhaust fan, or moving walls. The threshold is low: even relocating a toilet 2 feet triggers permit requirements because the drain arm (the horizontal run from the fixture to the main stack) must comply with IRC P2706, which limits trap-arm slope and length. If you're doing cosmetic work—replacing a toilet in place, new tile over existing drywall, vanity swap in the same footprint, or faucet upgrade—you do NOT need a permit. However, if your vanity swap involves relocating the plumbing supply lines or drain, a permit is required. The City of Maywood Building Department applies the 2022 California Building Code without local amendments, meaning you're bound by IRC rules for drainage, ventilation, waterproofing, and electrical protection. One critical detail specific to Maywood: the city's permit portal (accessed via the Maywood city website) requires all submissions to be digital—plans must be PDFs, not paper. If your contractor tries to file plans in person at City Hall, staff will reject them and require resubmission through the online system, costing 1–2 weeks of delay.

Waterproofing is the most commonly flagged issue in Maywood bathroom permits. If you're converting a tub to a shower or installing a new tub/shower assembly, the shower pan and walls must be waterproofed per IRC R702.4.2. Maywood does NOT accept tile alone as waterproofing—you must use a certified waterproofing membrane system beneath the tile. The most code-compliant approach is cement board + liquid or sheet membrane (e.g., RedGard, Kerdi) over studs. Some contractors use pan liners, but these are often flagged by Maywood inspectors because they can trap water if the tile grout fails. Specify your waterproofing system on your permit plan—this single detail prevents rejection and re-submission delays. Exhaust fans are required in all bathrooms (IRC M1505 requires 50–100 CFM depending on bathroom size) and must duct to the outside, not the attic. Maywood inspectors verify duct termination on-site; if you've ducted to the attic instead, you'll be cited and forced to reroute at your expense ($500–$1,500 in labor). The exhaust fan duct must be hard-piped with a damper on the roof or wall penetration—flexible dryer-vent hose does not meet code and will fail inspection.

Electrical work in bathrooms is strictly regulated under the 2022 California Code and requires a licensed electrician; you cannot pull a permit and do this work yourself as an owner-builder. All receptacles within 6 feet of a sink must be GFCI-protected (IRC E3902), and GFCI devices must be shown on your electrical plan. Lighting fixtures over the tub or shower require GFCI protection as well. If you're adding new circuits (e.g., for a heated floor, ventilation fan, or additional lighting), these must be shown on a one-line electrical diagram with breaker details and wire gauges. Maywood's plan review includes an electrical inspection by a city-certified inspector; they'll verify GFCI specs, circuit sizing, and wire routing during rough-in inspection. Many homeowners forget to include an electrical plan with their permit application; Maywood will reject the application until electrical is added. If you have an existing bathroom with a single 20-amp circuit serving receptacles and the exhaust fan, and you're only moving fixtures without adding new loads, you may not need a new circuit—but you must show the existing circuit on your plan and have an electrician verify capacity. Pressure-balancing valves on tub/shower trim are not required by code in Maywood, but they are required if you have a single-handle or cartridge valve with anti-scald features. The permit plan should specify the valve type and anti-scald rating.

Maywood's lead-paint disclosure adds a 2–3 week compliance layer if your home was built before 1978. California Prop 65 and HUD lead rules require that you provide a disclosure form to contractors and schedule a lead-inspection or risk-assessment before work begins. This is NOT a permit requirement per se, but the city's Building Department and contractors will ask for proof of compliance at permit issuance. Many homeowners skip this step and then encounter delays when the inspector arrives and contractor hasn't seen the disclosure. Get this done before you file the permit. If lead is found, you'll need a lead-safe work plan, which adds $200–$500 in cost and 1–2 weeks of timeline. Contractors who work on pre-1978 homes must be lead-certified; if your contractor isn't, the city can fine them and shut down your project. Verify your contractor's lead certification before hiring.

The inspection sequence for a full bathroom remodel in Maywood typically runs: rough plumbing (after walls are framed but before drywall), rough electrical (same timing), framing inspection (if walls are moved), and final inspection (after drywall, tile, and fixtures are installed). If you're not moving walls, the framing inspection is skipped. Plan for 4–6 weeks total timeline from permit approval to final sign-off, assuming no rejections. Maywood's permitting office processes plan review on a first-in-first-out basis; if your plans are incomplete, they'll issue a request for information (RFI) via email, and you lose your place in the queue. Build in buffer time: submit plans at least 3 weeks before your intended start date. The permit fee for a bathroom remodel in Maywood typically ranges from $300–$800 depending on valuation; if you declare $20,000 in labor and materials, expect a $400–$500 permit fee (roughly 2–2.5% of valuation). This fee does NOT include inspections or plan-review mark-ups. If plans are rejected and resubmitted, there is usually no additional fee, but delays compound. Hire a permit expediter ($300–$600) if this is your first remodel and you're uncertain about plan requirements.

Maywood's online permit portal and plan submission requirements

The City of Maywood Building Department requires all permit applications to be filed through its online portal; paper or in-person submissions are no longer accepted as of 2023. This is a significant procedural difference from unincorporated LA County areas, which still accept wet-signed plans at the counter. If you submit plans via the Maywood portal, you'll receive a confirmation email within 1 business day, and a plan-review engineer will be assigned within 3–5 days. The portal allows you to upload PDFs, image files, and a completed permit application form (available on the city website). Plans must be legible, 8.5x11 or 11x17 format, with a title block showing your name, address, project scope, and contractor information.

Common rejection reasons in Maywood's portal process include: missing waterproofing specification (the plan must state 'cement board + RedGard' or equivalent), no exhaust-fan duct termination detail, missing electrical plan, or trap-arm exceeding 42 inches without a vent solution. If your plans are incomplete, the engineer issues an RFI (request for information) via email; you have 2 weeks to respond. Resubmitted plans are treated as a new submission and go to the back of the review queue, delaying approval by 2–4 weeks. To avoid delays, have your contractor or permit expediter review plans against the Maywood checklist (available on the city website) before uploading.

Plan review typically takes 2–3 weeks in Maywood if plans are complete. Once approved, you'll receive a permit number via email. You then print the permit, post it on-site, and schedule inspections through the online portal or by calling the Building Department. The city allows you to request 'expedited review' for an additional fee ($100–$150), which prioritizes your plans and typically cuts review time to 1 week. If your contractor is experienced, this expedite fee may be worth the timeline savings, especially if you have a tight project deadline.

Waterproofing, exhaust fans, and the most common inspection failures

The single most common reason Maywood inspectors fail bathroom permits is inadequate waterproofing specification on plans. Many homeowners and contractors assume 'tile + grout' is sufficient; it is not per IRC R702.4.2. Tile and grout are vapor-permeable and will eventually fail if moisture penetrates. The code-compliant system is cement board (or equivalent backing) plus a liquid or sheet membrane applied to the full shower surround (walls and floor). Liquid membranes like RedGard are brushed on in 2–3 coats; sheet membranes like Schluter Kerdi are adhered with thinset. Both are acceptable in Maywood. Pan liners (vinyl or PVC under the tile) are also acceptable but must be installed correctly to prevent water pooling. The key: your permit plan must specify which system you're using, and the inspector will verify it's installed before drywall mud is applied (waterproofing must be visible and inspected, not buried).

Exhaust fans are required in all bathrooms and must duct to the exterior, not the attic or into adjacent wall cavities. Many Maywood homeowners skip this or assume the existing fan (ducted to the attic) is compliant. It is not. IRC M1505 requires 50 CFM minimum (100 CFM for bathrooms over 100 sq ft, or 50 CFM per square foot if larger). The duct must be hard-piped (metal or rigid plastic), not flexible dryer-vent hose. Dampers must be installed on the roof or wall termination to prevent back-drafting. Maywood inspectors verify duct routing on-site during rough-in inspection and again at final inspection. If the duct is flexible or terminates in the attic, the inspector will issue a citation and require rework before final approval.

A third common failure is P-trap arm length. When a fixture (toilet, sink) is relocated, the drain line from the fixture to the vertical stack is the 'trap arm.' IRC P2706 limits horizontal trap-arm runs to 42 inches. Many Maywood bathrooms are small, and relocating a toilet to the opposite wall can exceed 42 inches. If your layout requires a longer run, you have two options: (1) install a secondary vent stack that rises from the trap and vents through the roof (expensive, $1,500–$3,000), or (2) use a loop vent where the vent line loops above the overflow line of the fixture before dropping to the stack (also complex). If your permit plan shows a trap arm exceeding 42 inches without a vent solution, Maywood will reject it. Verify trap-arm length on your plumbing plan before submission; this single detail prevents rejection.
