In many situations, the answer is yes. If your remodeling project involves relocating plumbing lines, adding or upgrading electrical circuits, changing dryer vent routing, or modifying wall framing, the City of Las Vegas generally requires permits and scheduled inspections. These requirements are in place to ensure the work complies with current building, plumbing, and electrical codes. Simple cosmetic updates such as painting walls, replacing flooring, or installing new cabinets without altering plumbing or wiring may not require a permit. However, once you make changes to water supply lines, drain systems, gas lines, or electrical wiring, approval is typically mandatory. Inspectors review items such as proper drain sizing, venting methods, GFCI outlet protection, load calculations, and safe exterior vent termination. Failing to obtain permits can result in fines, complications during a home sale, failed inspections, or even denied insurance claims if damage occurs. Checking with the local building department before starting work helps prevent costly setbacks. Professional guidance ensures rough-in work and final installations meet code requirements and pass inspection efficiently.
