While obtaining a building permit may feel like an extra step in your home remodeling and construction plans, it plays a critical role in protecting you and your home.

Projects that relate to framing, electrical, mechanical or plumbing need a building permit. The City of Lenexa reviews your application to ensure your project complies with building and safety codes. Then, throughout construction, City inspectors verify everything is completed safely and correctly, helping prevent costly mistakes. Permits can also help ensure insurance will cover your property if you need to file a claim.

Permit applications are typically reviewed within five business days, and most inspections can be scheduled for the next business day — keeping your project moving forward efficiently. Our team is happy to help you with questions regarding contractors, applying for a permit and inspections.

How common building permits safeguard your home

Interior remodels

Permits for remodeling ensure you’re meeting critical safety standards. For example, ground fault circuit interrupters (GFCIs) are required in areas of your home where water is present to prevent electrocution. Windows and doors are required to be placed at certain locations to ensure that occupants can get out, and first responders can get in. Windows should be easy to open — not stuck, painted closed or blocked. Mechanical systems — your furnace and air conditioning — need to be properly installed and maintained by a professional, or they can cause hazards, such as dangerous gas and carbon monoxide leaks.

Basement finishes

A lot goes into refinishing a basement, and the City will help ensure it’s done correctly. The main water shutoff, HVAC and junction boxes must remain accessible. Plumbing lines are required to be sloped correctly to help prevent backups. Bedrooms must have access to the exterior with a proper egress window or exterior door. The underside of the stairs must be protected to retain integrity during a potential fire. Fireblocking and insulation are required to keep occupants safe. 

Swimming pools

It’s important that your pool is built safely for you and your guests. Some common inspection issues on new or refurbished pools include required fencing and pool alarms to prevent drowning of unexpected swimmers, clearance of overhead power lines or lack of GFCIs to prevent electrocution, and improper drain covers to prevent entrapment.

Decks and covered porches

Building something that holds the weight of people requires extra attention to detail. Submitting plans to the City is critical so plan examiners can verify structural integrity. Inspectors will check beam support, proper materials, handrail requirements and more. Staff will also review a submitted plot plan to ensure that the deck/porch meet required setbacks from the property.

Outdoor kitchens

To prevent fires, smoke or carbon monoxide buildup, outdoor kitchens and grills should not be located under roofs or overhangs made of combustible materials without fireproof shielding or manufacturer approval.

Roofing

Properly installed roofs protect your home from rain, wind and hail. Inspectors verify that the roof is installed to meet minimum requirements to help protect the longevity of your home. If you have solar panels, inspections can prevent electrical fires and other hazards from improper installation or faulty equipment.

Accessory structures

Detached garages, carports, gazebos, and sheds more than 120 square feet require a permit. Accessory structures should not be built as habitable dwelling units. The City can help determine proper location and zoning.

Scheduling inspections

Schedule your inspection at least one business day in advance through the Application and Permitting Portal at Lenexa.com/Permits or by calling 913.477.7725 during business hours.

If any of your projects require digging, call 1.800.DIG.SAFE to have your utility lines marked. Regular maintenance helps keep your home safe.
