If you’re planning a new landscape design and renovation in Mequon, Wisconsin, you may need a permit before beginning work. The City of Mequon Community Development Department reviews construction, grading, and outdoor projects to ensure they meet safety and zoning standards. Understanding the local rules early keeps your project on schedule and in compliance.
Overview of Mequon’s Permit Process
The city’s Building Inspection Division manages residential and commercial permits for exterior construction and landscaping improvements. Homeowners can find current forms and applications through the Forms and Permits page.
For residential landscaping or hardscaping, a permit is typically required when work involves:
- Installing or modifying retaining walls
- Adding large patio or paved surfaces that change impervious coverage
- Grading or excavation that alters land elevation
- Building pergolas, arbors, or seat walls considered accessory structures
- Adding drainage systems or erosion control measures
Projects that change water flow or grading are reviewed under Mequon’s erosion control and stormwater regulations to protect neighboring properties and natural areas.
Zoning, Drainage, and Structural Standards
Mequon’s Code of Ordinances outlines zoning and construction requirements for outdoor improvements. Some key guidelines include:
- Setbacks: All new structures, including patios and retaining walls, must maintain minimum distances from property lines.
- Erosion control: Projects disturbing more than 4,000 square feet or altering grade require an erosion control plan.
- Accessory structures: Pergolas, arbors, and small outdoor structures must meet the same height and placement rules as garages or sheds.
- Stormwater management: Drainage must remain contained on-site and cannot discharge to neighboring properties or roadways.
If your project involves site grading or new impervious surfaces, the Engineering Division may review plans for compliance with drainage and stormwater requirements.
How to Apply for a Landscaping Permit in Mequon?
Permit applications can be submitted online or in person through the City of Mequon Inspections Division. Most landscape and hardscape applications require:
- A completed permit form
- A recent property survey
- A scaled site plan showing elevations, drainage, and structure placement
- Construction details for retaining walls or structures
After submittal, the Building Department reviews the documents, may request revisions, and issues a permit once approved. Always wait for official approval before breaking ground to avoid penalties or stop-work orders.
