The Ultimate Landlord’s Checklist for Passing Your Rental Inspection the First Time

As a landlord in Denver or Boulder, getting your property ready for a rental license inspection can feel like a big task — but with the right preparation, you can pass on the first go. By tackling the common trouble spots before your inspector arrives, you’ll not only save time and money but also protect your tenants and your investment. Here’s the ultimate checklist to help you breeze through your local rental inspection.

Denver

• The City of Denver mandates a residential rental property inspection as part of its licensing program.

• The checklist used by inspectors is based on the Residential Rental Program Checklist.

• Licensed inspectors must hold both (a) a home inspector certification (e.g., InterNACHI) and (b) an ICC R5, C5, or C8 Combination Building Inspector certification.

• Your inspection report and application must be submitted within 90 days of the inspection to be valid.

Boulder

• Boulder requires a rental licensing inspection for long-term rentals, using a 4-part checklist covering structure, plumbing, electrical, and fire safety.

• Inspectors must be licensed through Boulder’s rental licensing program.

• According to the Boulder checklist, life safety is a priority: smoke alarms, CO alarms, building condition, etc.

• Smoke Detectors
  
  
• Install a working smoke detector inside each bedroom.
  
• Install detectors outside sleeping areas, within 15 feet of bedroom entrances.
  
• Make sure there’s a smoke detector on every level, including basements.
  
• Age matters: detectors should be less than 10 years old (or within manufacturer’s life expectancy).
  
• Carbon Monoxide (CO) Alarms
  
• Required on every level.
  
• Especially required within 15 feet of sleeping areas.
  
• Test for functionality before the inspection.
  
• Fire Extinguisher
  
• Should be present, accessible, and up to date (check Denver guidebook for specific requirements).
  

• Ensure that GFCI (Ground Fault Circuit Interrupter) outlets are installed in bathrooms (and other required areas, per Denver’s code).
  
• Check that all outlets and switches are functional and not damaged.
  
• Look for exposed wiring, missing outlet covers, or unsafe DIY electrical fixes.

• Walls, Ceilings & Floors: Repair large cracks or holes; ensure finishes are safe.
  
• Windows & Doors: They should open and close properly, provide egress where required, and have intact glass and hardware. 
• Stairs & Railings: Make sure they are secure, stable, and meet code.
• Light & Ventilation: Rooms must have working light fixtures and appropriate ventilation. For Boulder, check their minimum standards.

• Confirm that sinks, toilets, and drains work without leaks.
  
• Make sure there is adequate hot water and that temperature controls are functional.
  
• Check water pressure and test for any slow drains or clogs.
  
• Bathrooms must have properly installed plumbing fixtures, and all fixtures must be secure.

• Furnaces / Heating: Should be safe and functional. No hazards like improper ventilation or unprotected burners.
  
• Water Heater: Make sure it’s stable, venting correctly (if gas), and has no visible leaks.
• Ducts / Vents: Ensure vents are free of obstructions, and the system is properly maintained.

• Inspect for signs of insects, rodents, or vermin: droppings, nesting, or damage.
  
• Make sure the property is reasonably clean and maintained to prevent pest problems.
  
• Seal gaps or cracks where pests may enter.

• Provide all relevant keys (doors, common areas) to the inspector.
  
• Coordinate with your tenants: give notice ahead of time and request access.
  
• Make sure common areas are clear of clutter so the inspector can do a full walk-through.

• Previous Inspection Reports: If you’ve done prior inspections, have those on hand.
  
• Building Diagrams / Floor Plans: Helpful, but not always required—depends on your inspector.
• Safety Device Records: Be ready to show proof of installation or replacement dates for smoke/CO alarms, fire extinguishers, etc.

• Walk through your property at least 1–2 days before the inspection.
  
• Use a checklist (ideally based on Denver’s or Boulder’s published inspection checklist) and mark off everything.
  
• Take photos or video to document pre-inspection condition.
  
• Fix any low-hanging issues (dead batteries in alarms, loose covers, leaks) before the inspector arrives.

• If there are any violations, get a written list from your inspector.
  
• Schedule and complete repaired items quickly — many inspectors (including us) will re-inspect to verify corrections.
  
• Once you pass, keep your inspection report because Denver requires the inspection to be valid for your license application (and renewal).
• Plan when to apply or renew your rental license — inspections are required every 4 years in both Denver and Boulder. (Rental Inspections LLC)
