Acquiring a permit for a single-family home requires submittal of an application for residential permit, a site plan containing the items listed below under Site Plan Requirements, and two sets of plans with the information listed in Residential Plan Submittal Requirements. If the home will be constructed on a lot that is not located in a major subdivision, a copy of the recorded plat for that particular property may be required. If on-site wastewater (septic) systems and/or private water supply (well) are required on the lot, Permits staff will begin this process with the application of the building permit. Fees for the on-site wastewater and water systems are paid for at the time of application. Plans will be reviewed in the order they are received by the Plan Review staff. The permit will be issued when all outstanding issues are completed and the applicable permit fees shall be paid at that time.
Reminder: A Certificate of Occupancy is required before occupancy of any new or relocated manufactured home.
A completed permit application for a single-family home.
A site plan meeting all of the specification listed in the Site Plan Requirements
Two sets of plans detailing the work to be performed. The building plans shall detail the construction in accordance with the Residential Plan Submittal Requirements as it applies to the particular project.
Plans will be reviewed in the order they are received by the Plan Review staff.
The permit will be issued when all outstanding issues are completed, and the applicable permit fees shall be paid at that time.
A preliminary site plan is required before permits are issued. A final (as-built) site plan may be required prior to the issuance of a Certificate of Occupancy. A good resource for a site plan is a survey issued for a recent mortgage or refinance closing.
A site plan includes the entire lot, drawn to scale, showing:
- Lot lines with dimensions and road frontage delineated; existing or proposed driveways, parking spaces and walkways, with width and surface material described.
- All existing and proposed buildings or other structures, with overall dimensions given and their setback(s) from nearest property lines clearly delineated.
- Existing or proposed well, septic tank and drainfield location(s) or sewer and water easements and proposed connection location(s).
- All surface waters; FEMA 100-year flood fringe and floodway lines (or approximate 100-year flood line in unnumbered A Zones); flood hazard soils areas (adjust flood hazard soils to Wake County topography or field surveyed low points as appropriate); wetlands; reserved open spaces; the location, dimensions and arrangements of all drainageway, watershed, riparian, and other buffers and their associated required setbacks; the location of any existing or proposed easements (widths listed).
- A title block indicating parcel identification number (PIN), north arrow and scale of the site plan, bar scale (for preliminary plans, indicate that it is a preliminary plan), name of Professional Land Surveyor, Landscape Architect, Professional Engineer, the landowner or his authorized agent’s, signature, and for licensed professionals, seal of the person who prepared the plan, date map prepared (and any revision dates).
- For as-built final plans, indicate that it is an as-built plan and provide name of the Professional Land Surveyor who prepared the plan, his signature and seal and date map prepared (and any revision dates).
- If parcel is less than 5 acres, scales of 1" = 20', 30', 40', 50', 60' or 100' are acceptable on paper no larger that 11" x 17".
- For a parcel of 5 acres or more, scales of 1” = 100’, 200’, 300’, 400’ or 500’ are acceptable in addition to the scales listed above and may be on any size paper. If the paper is larger than 11” x 17” an inset or separate sheet must also be provided showing the proposed construction at a scale of 1” = 20’, 30’, 40’, 50’, 60’ or 100’.
- All existing and proposed impervious surfaces shall be clearly delineated and listed in sq. ft. and as a percentage of the total net lot size listed.
- Location, type and relevant dimensions and capacities of stormwater management structures and other devices (if stormwater management is required), plus associated easements (show dimensions).
