Required Documents for a Bathroom Remodel Permit in Greeley
You'll typically need the following when applying for a bathroom remodel permit in Greeley:
- Permit application form(s) — Property address, owner info, contractor info, and scope description. You may need separate applications for building, plumbing, electrical, and mechanical permits.
- Floor plans (existing and proposed) — Drawn to scale showing the current bathroom layout and the proposed changes. Must show all fixture locations, wall modifications, and door swings. For simple projects, a neat hand-drawn sketch may be accepted.
- Plumbing riser diagram — Required if moving or adding fixtures. Shows drain/waste/vent (DWV) pipe routing, pipe sizes, fixture connections, trap locations, vent terminations, and supply line routing.
- Electrical plan — Shows circuit layout, outlet locations with GFCI protection, exhaust fan wiring, lighting circuits, and dedicated 20-amp bathroom circuit per NEC 210.11(C)(3).
- Ventilation details — Exhaust fan CFM rating (minimum 50 CFM intermittent or 20 CFM continuous per IRC R303.3), duct routing to exterior, and termination point. Must vent directly outside — never into an attic or soffit.
- Structural details (if modifying walls) — Required if removing or modifying load-bearing walls. May need engineer-stamped drawings showing headers, posts, and load paths. Even non-load-bearing wall removal may need a building permit.
Requirements may vary. Contact Building Inspection Division for the complete list of required documents.
Common Mistakes to Avoid in Greeley
Moving plumbing without a permit
The most common bathroom remodel violation. Relocating a toilet, shower, or sink drain involves modifying the drain/waste/vent system, which must be inspected for proper slope, pipe sizing, and venting. Unpermitted plumbing work is a major red flag during home sales and can cause serious drainage problems.
Not venting drains properly
Every fixture trap needs a vent within a specific distance (per IRC Table P3105.1 — e.g., a 1-1/2 inch trap arm can be no more than about 6 feet from the vent). Without proper venting, drains gurgle, drain slowly, and can siphon the trap seal, allowing sewer gas into your home. This is one of the most common DIY plumbing failures.
Skipping GFCI protection
All receptacles in bathrooms require GFCI protection per NEC 210.8(A)(1). This is non-negotiable — water and electricity are a lethal combination. You also need at least one dedicated 20-amp branch circuit for bathroom receptacles (NEC 210.11(C)(3)) and at least one receptacle within 36 inches of each basin edge.
Inadequate bathroom ventilation
IRC R303.3 requires either an operable window (minimum 3 sq ft, half openable) or a mechanical exhaust fan rated at minimum 50 CFM intermittent / 20 CFM continuous. Many remodelers skip the fan or install one with insufficient airflow. The exhaust must terminate directly outside — venting into the attic causes mold and rot.
Improper shower waterproofing
Failing to install a continuous waterproof membrane behind shower tile is a recipe for hidden water damage. The liner must extend up walls at least 2 inches above the finished curb height. The shower pan must pass a flood test — 2 inches of water held for 15 minutes minimum with no leaking (IRC P2709). Use cement backer board in wet areas, not moisture-resistant drywall.
Closing walls before rough-in inspections
All plumbing pipes, electrical wiring, and framing must be inspected while still visible. If you install drywall or tile before the rough-in inspection, you'll be required to tear it out so the inspector can verify the work. This is expensive and entirely preventable — schedule your inspections before closing anything up.
Venting the exhaust fan into the attic
The exhaust fan must terminate outside the building envelope — through the roof or an exterior sidewall. Dumping warm, moist air into the attic causes condensation, mold growth, and wood rot. This is a common code violation that inspectors catch immediately.
Not getting permits at all
Unpermitted bathroom work is consistently discovered during home sales. Buyers' inspectors and appraisers flag it, title companies may require resolution, and you may have to tear out finished work for retroactive inspection. The permit cost is a fraction of the remodel cost — don't skip it.
Required Inspections in Greeley
Most bathroom remodel projects in Greeley require inspections at each construction stage:
Rough-In Plumbing Inspection
When: After all drain, waste, vent, and supply pipes are installed but before walls are closed — the inspector must see all piping
Drain pipe routing, sizing, and slope (1/4 inch per foot for pipes under 3 inches), supply line routing and pipe sizes, trap-to-vent distances per IRC Table P3105.1, proper pipe support and hangers, and pipes are typically pressure-tested for leaks.
Common failures: Incorrect drain slope, vent too far from trap, undersized pipes, missing cleanouts, drain lines not properly supported.
Shower Pan / Waterproofing Inspection
When: After the shower pan liner or waterproof membrane is installed but before tile is applied
Continuous waterproof membrane properly installed, liner turned up walls at least 2 inches above curb height, drain connection sealed, and a flood test — pan filled with 2 inches of water and held for 15 minutes minimum with no leaking (IRC P2709).
Common failures: Liner not extending high enough on walls, leaking at drain connection, membrane punctures or gaps, failing the flood test.
Rough-In Electrical Inspection
When: After wiring is run but before walls are closed — often inspected at the same time as rough-in plumbing
Wire gauge appropriate for circuit amperage, circuit routing and box placement, GFCI protection planned for all bathroom receptacles, dedicated 20-amp bathroom circuit, exhaust fan wiring and switch, and wet-location-rated fixtures in shower/tub areas.
Common failures: Missing dedicated 20-amp bathroom circuit, GFCI not provided for all receptacles, incorrect wire gauge, no receptacle within 36 inches of basin.
Final Inspection
When: After all work is complete — fixtures installed, walls finished, everything operational
All fixtures installed and functioning, GFCI outlets tested, exhaust fan operational and vented to exterior, plumbing tested with no leaks, proper clearances (21 inches minimum in front of toilet and sink, 24 inches in front of shower entry), minimum 80-inch ceiling height in front of fixtures, and overall compliance with approved plans.
Common failures: Exhaust fan not vented to exterior, GFCI outlets not functioning, insufficient clearances around fixtures, plumbing leaks at connections.
Schedule inspections with Building Inspection Division at (970) 350-9830 at least 24–48 hours in advance.
Pro Tips for Bathroom Remodel Permits in Greeley
- Install an exhaust fan even if you have a window — it's the most effective way to prevent mold and moisture damage. Size it at minimum 50 CFM, or 1 CFM per square foot for larger bathrooms. Always vent directly to the exterior, never into the attic.
- All bathroom receptacles must have GFCI protection (NEC 210.8(A)(1)), and you need at least one dedicated 20-amp circuit for bathroom outlets (NEC 210.11(C)(3)). Plan at least one receptacle within 36 inches of each sink basin.
- Use a waterproof membrane (sheet membrane like Kerdi or liquid-applied like RedGard) behind all shower and tub tile — not just the shower floor. Extend it at least 3 inches above the showerhead rough-in height. Use cement backer board, not moisture-resistant drywall, in wet areas.
- Test your shower pan before tiling — fill it with 2 inches of water and wait 15 minutes. This is code-required (IRC P2709) and much cheaper to fix before tile than after.
- Every fixture drain needs a vent within a specific distance. If a conventional vent is impractical, ask your building department about Air Admittance Valves (AAVs) — they're permitted under IRC P3114 and accepted in many jurisdictions as an alternative.
- Take photos of all rough-in plumbing and electrical before closing walls. These are invaluable for future maintenance, repairs, and if you ever sell the home.
- Budget for 3–4 separate inspections and the scheduling time involved. Each inspection typically needs 24–48 hours advance notice. Build this into your project timeline.
- Pull permits before starting work, not after. Retroactive permits cost more, require tearing out finished work for inspection, and may not be approved.
- If adding a bathroom in a basement, you'll likely need a sewage ejector pump since the fixtures will be below the main sewer line. This adds cost and requires its own inspection.
- Plan the full scope upfront. Adding work mid-project (deciding to move the toilet after you've already permitted only a vanity swap) requires re-permitting, re-review, and delays.
