Before You Build in Noblesville, IN: Permit & Rule Checklist (2026)

Noblesville regulates residential fence height under Section 159.121 (Accessory Uses and Structures) of the Unified Development Ordinance (Title XV, Chapter 159, Land Usage). The maximum height in a required side or rear yard is seven (7) feet, and the maximum in any front yard is four (4) feet. A yard that abuts a street to which access is prohibited is treated as a side or rear yard, allowing a fence up to seven feet on that frontage. Nonresidential fences are restricted by the requirements of the underlying zoning district or a maximum of eight (8) feet, whichever is less.

Noblesville UDO Section 159.121 permits residential fences as 'open or solid fences, latticework, screens, or walls' without restricting to a specific material list. Common residential choices in Hamilton County - wood (cedar, pine, board-on-board), vinyl/PVC, wrought iron, aluminum, and standard chain link - are allowed by the UDO subject to the height limits (7 ft side/rear, 4 ft front yard). Screening walls between nonresidential and residential uses must be wood or masonry under Article 12. Pool barriers must meet the Indiana Residential Code Section R326 material rules adopted under IC 22-12.

Retaining walls in Noblesville are governed by the Unified Development Ordinance and the Indiana Residential Code (675 IAC 14-4.4) adopted statewide under IC 22-12. Per the UDO, no retaining wall shall exceed eight (8) feet in height. Walls 48 inches or more in height may be tiered or terraced; the area between each tier must remain pervious and may not be paved or otherwise covered with impervious materials. The Noblesville Building Commissioner may require engineering on any retaining wall as deemed necessary, and walls over 4 feet (bottom of footing to top of wall) generally require a permit and engineered design under the Indiana Residential Code.

Neither the Noblesville Code of Ordinances nor the Unified Development Ordinance contains a 'good-side-out' requirement, a partition-fence statute, or a mandatory cost-sharing rule for boundary fences between residential neighbors. Boundary fence disputes are private civil matters under Indiana common law. The City regulates fence location only with respect to property lines, easements, and zoning setbacks - it does not survey property lines or adjudicate cost-sharing claims between neighbors.

Noblesville requires a fence permit from the Department of Planning and Development (16 S 10th Street, 317-776-6325) before installing a residential or nonresidential fence. Applications are submitted digitally through the Citizen Self-Service (CSS) Permit Portal at noblesville.in.gov/applications. The plan review confirms compliance with UDO Section 159.121 (height, location), Article 12 (landscaping and screening), the underlying zoning district, and any recorded easements. Fence permits in Noblesville carry a $25 administrative fee. Statewide building safety standards under IC 22-12 and the Indiana Residential Code (675 IAC 14-4.4) also apply.

Residential pool barriers in Noblesville are governed by Section 159.121 of the UDO (which requires a barrier at least four feet in height for permanent pools and/or a compliant safety cover) and by the Indiana Residential Code 2020, Section R326 (Swimming Pools, Spas and Hot Tubs) adopted statewide under IC 22-12 / 675 IAC 14-4.4. The IRC sets the technical floor: minimum 48-inch barrier height, no opening that allows a 4-inch sphere to pass, self-closing and self-latching gates that open outward away from the pool, and additional protections where a dwelling wall serves as part of the barrier.

All swimming pools in Noblesville require a building permit issued by the Department of Planning and Development (16 S 10th Street, 317-776-6325). The City's Swimming Pools - New Construction guide requires four inspections: Lower and Upper Bonding, Pre-pour Engineering, Swimming Pool Engineering Final, and Building Final prior to occupancy. Pools must comply with UDO Section 159.121 (barrier requirements and accessory structure regulations), Section R326 of the Indiana Residential Code 2020 (675 IAC 14-4.4) adopted under IC 22-12, and Indiana Plumbing Commission requirements under IC 25-28.5.

Noblesville pool fencing is governed by UDO Section 159.121 and the Indiana Residential Code 2020 Section R326 (Swimming Pools, Spas and Hot Tubs) adopted statewide under IC 22-12 / 675 IAC 14-4.4. UDO Section 159.121 requires permanent pools to be protected by a fence at least four feet in height and/or a compliant safety pool cover. Section R326 sets the technical floor: 48 inches above grade minimum, openings under 4 inches, self-closing/self-latching gates opening outward, and additional alarm or cover protections where a dwelling wall serves as the barrier.

Hot tubs and spas in Noblesville are accessory structures regulated under UDO Section 159.121 and Section R326 of the Indiana Residential Code 2020 (675 IAC 14-4.4) adopted statewide under IC 22-12. A hot tub or spa equipped with a safety cover complying with ASTM F1346 is exempt from the otherwise-applicable pool-barrier requirements of Section R326. A building permit and bonding inspection are still required, plumbing connections must be by an Indiana-licensed plumber under IC 25-28.5, and the City of Noblesville's Department of Planning and Development administers permitting at 317-776-6325.

Noblesville pool safety rules come from UDO Section 159.121 and Section R326 (Swimming Pools, Spas and Hot Tubs) of the Indiana Residential Code 2020 adopted under IC 22-12 / 675 IAC 14-4.4. Required safety measures include a four-foot (UDO) / 48-inch (IRC) compliant barrier, self-closing/self-latching gates that open outward, climb-prevention requirements, suction-entrapment protection (Virginia Graeme Baker Pool and Spa Safety Act compliance), door alarms or powered safety covers where a dwelling wall is part of the barrier, and electrical bonding inspections by the City of Noblesville before bond wires are covered.

Noblesville UDO Sec. 159.121 permits exactly one Accessory Dwelling Unit (ADU) per lot or parcel, but with strict limitations: the ADU is initially intended for relatives or resident domestic employees, must share utilities with the principal building (separate metering is prohibited), must blend architecturally with the principal building, may not have a front-facade entrance or exterior stairway, and must keep the principal building's appearance as a single-family residence. Indiana has no statewide ADU mandate, and Noblesville's posture is markedly more restrictive than Carmel's relatively permissive ADU framework.

Converting an existing attached or detached garage into habitable living space in Noblesville requires a building permit under Chapter 154 (Building Code) and compliance with the Indiana Residential Code (adopted under IC 22-12). The new space must meet residential code minimums for ceiling height, egress windows, smoke and CO alarms, insulation, and energy code. Because conversion removes a parking space, alternative off-street parking must be provided, and if used as a second dwelling unit it triggers the ADU rules in UDO Sec. 159.121.

Noblesville UDO Sec. 159.121 caps combined accessory structures (sheds, detached garages, gazebos, pool houses) at 50 percent of the principal building's footprint or 1,000 sq ft (whichever is less) on lots 1 acre or smaller, at a maximum 17-foot height. Side and rear setbacks default to the underlying zoning district; structures over 200 sq ft require a building permit through the Citizen Permit Portal ($75 base fee). Larger lots get larger allowances (2,000 sq ft on 1-5 acres; 4,000 sq ft on 5+ acres).

Noblesville UDO Sec. 159.106 permits manufactured homes (which include some tiny home designs) as scattered-site residences in all residential districts, but only if they meet single-family dwelling standards: double-section construction, minimum square footage for the zoning district, longest side facing the street, and attachment to a permanent foundation per the Indiana One- and Two-Family Dwelling code. Tiny homes on wheels (THOWs) and stick-built tiny homes under the minimum dwelling square footage for the district are not permitted as primary residences. ADU-style tiny homes still must comply with Sec. 159.121.

Noblesville UDO Sec. 159.121 treats carports as accessory structures and lists them alongside garages, canopies, and porte-cocheres. Carports for private residential use are permitted in all residential districts, subject to the same combined accessory size cap (1,000 sq ft on lots ≤ 1 acre) and setback rules as sheds. A building permit is required for any carport over 200 sq ft, and the carport must meet the underlying district's front and side setbacks — front-yard placement is generally prohibited unless integrated with the principal driveway.

Recreational fires (including backyard fire pits) in the City of Noblesville are regulated by §92.12 (Controlled Burning) of the Noblesville Code of Ordinances and Ordinance 50-10-09 (Noblesville Fire Prevention Code), adopted by the Common Council on October 27, 2009. §92.12(A) states: "No person within the City shall burn any rubbish, trash, garbage, yard waste, leaves, construction materials, tree limbs, shrubbery trimmings, or dangerous materials at any time within the City limits." §92.12(B)(1)(d) permits "Fires used for recreational or cooking purposes" with prior approval of the Fire Chief, which §92.12(D) and §92.14(II)(B) defines as a no-cost Open Burn Permit issued by the Noblesville Fire Department (Standard or Annual). Per §92.12(B)(2), all exempted recreational fires must: (a) burn only wood products; (b) be attended at all times until completely extinguished; (c) be extinguished if they cause an air pollution problem, nuisance, or fire hazard; (d) not be conducted during unfavorable meteorological conditions (temperature inversions, high winds, air stagnation); and (e) be a minimum of 25 feet from any combustible material or any structure. The NFD Residential Open Burning Regulations apply 2008 InFC 307.4 to allow a 15 ft setback when burning in an approved noncombustible container (vented with enclosed sides and bottom) at a private residential building with fewer than 4 units.

Outdoor open burning in Noblesville is governed by §92.12 (Controlled Burning) of the Noblesville Fire Prevention Code (Ord. 50-10-09) and, in Noblesville Township and beyond, 326 IAC 4-1 (Indiana Department of Environmental Management / IDEM Open Burning Rule) plus 2008 Indiana Fire Code (InFC) 307. §92.12(A) prohibits burning of any rubbish, trash, garbage, yard waste, leaves, construction materials, tree limbs, shrubbery trimmings, or dangerous materials inside City limits at any time. §92.12(B) carves out narrow exemptions, all requiring prior approval (Open Burn Permit) from the Fire Chief: (1) Twelfth Night Ceremonies, school pep rallies, scouting activities, and recreational/cooking fires; and (3) burning of natural-disaster refuse, fire training, emergency burning of spilled petroleum, prescribed prairie/native vegetation burns per 326 IAC 4, agricultural burning per 326 IAC 4-1-3, and dignified American flag burning by approved organizations (VFW, American Legion, Knights of Columbus, Elk's Lodge, BSA, GSA). §92.12(C) (Non-Residential Burning) requires a stationary incinerator meeting IDEM standards, operating only between 7:00 A.M. and 7:00 P.M. §92.99(D) sets the penalty at up to $200.00 per day, each day a separate violation.

Per Noblesville UDC § 159.083 (Preservation of Existing Natural Features) and § 159.183, clearance of trees and vegetation during the land development process is limited to that necessary for and directly related to the construction of improvements specifically authorized by the improvement location permit. No trees may be removed from a development — nor any change of grade affected — until the primary plat is approved. Removal of any street tree or tree on City property requires an Urban Forester permit under Code Chapter 97. Tree removal on a fully private lot outside development review is generally permitted without a City permit.

Noblesville is a Tree City USA community (35+ consecutive years — longest streak in Hamilton County). Under Code Chapter 97 (Street Trees) and § 97.12 (Regular Tree Care), routine care of street trees in the right-of-way by an owner-occupant — watering, raking, leaf/twig cleanup — does NOT require a permit. However, any certified arborist hired to perform routine street tree care must first secure a permit from the City's Urban Forester. Owner-occupant trimming beyond basic maintenance also requires Urban Forester approval. All work must follow the Arboricultural Specifications Manual (January 2024) and Ordinance 8-3-09.

Drinking water in Noblesville is supplied by Indiana American Water (INAW) — Noblesville Operations (PWS ID IN5229015), serving approximately 41,078 residents from three well fields drawing groundwater from Hamilton County aquifers. The City does NOT operate its own potable water utility (Noblesville Utilities Department handles wastewater/sewer only). When drought conditions arise in central Indiana, INAW imposes mandatory outdoor watering restrictions — typically alternate-day watering or 2-days-per-week mandatory limits — under its Water Conservation Ordinance. Noblesville does not have a standing year-round outdoor watering schedule.
