Rooted in the City of Oaks
Most routine landscaping in Raleigh, planting, mulching, sod, and general yard maintenance, needs no permit at all. Permits come into play when a project builds a structure, moves serious amounts of soil, or connects to the water system. The big triggers are: any new fence (zoning permit), retaining walls over five feet of vertical relief (building permit), decks and covered porches (residential permit), irrigation systems (backflow prevention requirements), work on trees in the City right of way (Tree Impact Permit), and land disturbance of 12,000 square feet or more (land disturbance permit). Below we break down each one, with links to the official City of Raleigh pages.
We install landscapes across Raleigh every week, and permits are part of our normal workflow. This guide is general information, not legal advice. Rules change, and every lot is different, so confirm your project through the City of Raleigh Permit and Development Portal or the Planning and Development Customer Service Center at 919-996-2500 before you build.

Retaining Walls
Raleigh requires a building permit when a retaining wall, or a system of walls, provides cumulative vertical relief greater than five feet within a horizontal separation of 50 feet or less. Walls under five feet generally do not need a building permit, but a zoning permit is still required in most of those cases, and a shorter wall that sits close to a structure may still need engineered design. See the City’s retaining wall permit page and confirm residential specifics through the Permit and Development Portal.
Fences
A zoning permit is required when a fence is installed on any property in Raleigh. You also need permits before replacing 50 percent or more of an existing fence, and even smaller replacements need a zoning permit if the material, height, or location changes. Commercial fences over six feet may additionally need a building permit. Details are on the City’s fence permit page.
Patios, Decks, and Hardscape
Decks, screened porches, and balconies go through a residential permit submitted in the Permit and Development Portal, with a site plan and, for roofed structures, elevation drawings. One number worth knowing for patios and other hardscape: projects adding 800 square feet or more of impervious surface, or concentrating stormwater flow, must meet the City’s Lot Grading Plan requirements. Historic district properties need a Certificate of Appropriateness first. Start at the City’s deck and porch permit page.
Irrigation and Backflow Prevention
Every irrigation system tied to City water needs backflow protection under Raleigh’s Cross Connection Control Program. Irrigation backflow assemblies sit just after the water meter and must be tested by a City of Raleigh Certified Tester under City Code Section 8-2154. Residential irrigation assemblies must be tested by July 1 every three years; commercial irrigation assemblies must be tested annually by July 1. Non-compliance brings fees or disconnection. See the City’s irrigation systems page and the backflow testing schedule.
Tree Removal
A Tree Impact Permit is required for any work near or to a tree on City-owned or maintained property, including street trees in the right of way. That covers pruning, removal, and even trenching or grading within the critical root zone, defined as a radius of 1.25 feet per inch of trunk diameter. Trees on your own private property generally do not need this permit, but lots with recorded tree conservation areas are different: removal there requires a tree conservation permit under conditions in UDO Section 9.1.6, such as an arborist certifying the tree is unsafe or unhealthy. Not sure whether your right of way or a conservation area is involved? Check with the City of Raleigh Permit and Development Portal.
Grading and Drainage
Any land-disturbing activity of 12,000 square feet or more requires a land disturbance permit before work starts, per the City’s stormwater plan review page. Erosion control measures are still required on single-family lots regardless of size. Inside watershed protection overlay districts, development activities, including minor improvements, need a separate Watershed Permit regardless of disturbance size. Impervious surface limits for residential lots also vary by zoning and lot age, so check yours first.
FAQ
Do I need a permit to plant trees or shrubs in Raleigh?
Not on your own property in typical cases. You do need a Tree Impact Permit to plant, prune, or remove trees in the City right of way, and tree conservation areas have their own rules.
Does a paver patio need a permit in Raleigh?
A basic ground-level patio often does not need a building permit, but adding 800 or more square feet of impervious surface triggers Lot Grading Plan requirements, and impervious limits apply to your lot. Confirm through the Permit and Development Portal.
Who pulls the permit, the homeowner or the contractor?
Either can apply through the Permit and Development Portal. When we handle a project that needs one, we manage the permit as part of the job.
