Do you need a building permit in Nichols Hills, Oklahoma?

Nichols Hills requires a city building permit for any type of construction work; the city also requires approval for changes in use and work that constructs, alters, moves or adds to a building or structure.1 Nichols Hills adopts the International Residential Code with state and city modifications for residential construction.8 Electrical work needs an electrical permit, and work involving plumbing, water, gas, heat/air or sewer needs a separate city permit.1 Ask Building Inspections to identify the building and trade applications for your proposed work.1

Who issues building permits in Nichols Hills, and how do you apply?

Nichols Hills Building Inspections & Code Enforcement is the municipal contact for building applications, and the Permits and Licensing Clerk issues city building and trade permits.1 Licenses and permits are available at Public Works, 1009 NW 75th Street; call 405-843-5222 for information.1 The city accepts applications and documentation by email through Building Inspections on its official page.1 Nichols Hills inspections are scheduled directly with the inspectors at 405-245-6532.1 Ask that office for the current fee, required plans and inspection sequence before committing to a construction schedule.1

Does Nichols Hills have zoning, lot-size rules and building limits?

Nichols Hills has municipal zoning, including the E-2 Urban Estate and R-2 Two-Family Residential districts; the rules depend on the property's district.5 In Nichols Hills' E-2 district, the minimum lot size is 30,000 square feet and minimum width at the front property line is 125 feet.7 E-2 building coverage cannot exceed 30% of the lot area within the district's setback lines, rather than the entire lot.9 E-2 main buildings have a maximum height of 35 feet and accessory buildings, structures and uses have a maximum height of 25 feet.10 R-2 defined structures have an 80% coverage limit within setback lines and a 35-foot maximum building height.1112 Ask Nichols Hills Planning & Zoning to confirm the district and applicable setbacks for the parcel.13

How do septic permits work inside Nichols Hills?

Oklahoma DEQ handles on-site sewage authorization inside Nichols Hills; municipal building approval does not replace the state septic approval.41 Before installing a new septic system or modifying an existing system in Nichols Hills, obtain DEQ's Authorization to Construct.6 DEQ must review the Report for On-Site Sewage before issuing that authorization.6 A new or modified system must be inspected and approved by DEQ, or installed, self-inspected and approved by a certified installer, before operation.14 We could not confirm whether Nichols Hills requires public sewer connection when available; ask Building Inspections about sewer connection before commissioning a septic design.1

Can you live in an RV or tiny home in Nichols Hills?

Nichols Hills prohibits occupying a travel trailer, motor home or other motor vehicle as housing on either a permanent or temporary basis.3 Living in an RV while building a house therefore falls within Nichols Hills' temporary-occupancy prohibition.15 We could not confirm a complete rule for every type of tiny home, an independent accessory dwelling or minimum dwelling floor area; ask Nichols Hills Planning & Zoning about the specific design and use.13 A proposed small site-built home still faces the city's construction-permit requirement and adopted residential code.18

Building a home in Nichols Hills: what should you do before buying?

Start by asking Nichols Hills Planning & Zoning to confirm the parcel's zoning district, then test the proposed house against that district's dimensional rules.135 Next, discuss the building application and relevant trade permits with Nichols Hills Building Inspections; submit the requested applications and documentation through the city's email submission option.1 Resolve sewer connection with the city, or obtain DEQ authorization before installing or modifying an on-site sewage system.16 For subdivision applications, Nichols Hills Planning Commission recommends approval or denial and City Council makes the final decision.13 For land outside Nichols Hills city limits, use the Oklahoma County guide for the county's unincorporated-area building-permit answer.16

Watch-outs

  • Nichols Hills prohibits temporary RV occupancy as well as permanent vehicle housing, so an RV is not an allowed construction-time residence.3
  • Nichols Hills E-2 and R-2 coverage limits apply to area within setback lines; do not calculate buildable coverage using the entire parcel.911
  • We could not confirm a Nichols Hills owner-builder exemption or current building-permit fees; ask Building Inspections before budgeting or arranging the work.1
