Some RestrictionsTree Trimming
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.

Some RestrictionsTree Removal & Heritage Trees
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.

Some RestrictionsWater Restrictions
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.

Some RestrictionsRainwater Harvesting
Rainwater harvesting is fully legal in Indiana with no statewide restriction on residential rainwater collection. Noblesville recognizes 'rain barrel' as a defined feature ('a container that collects rainwater managing rooftop runoff') in its zoning ordinance. The City does not require a permit for typical residential rain barrels used for outdoor irrigation (gardens, lawns). Complex systems involving large cistern storage, alterations to potable plumbing, or non-potable indoor connections may require building/plumbing permits under the Indiana Plumbing Code. The Hamilton County Soil & Water Conservation District (based in Noblesville) sells low-cost rain barrels.

Few RestrictionsNative Plants
Noblesville encourages plant material 'normally grown in Central Indiana' that is 'capable of withstanding the extremes of individual site microclimates' under UDC § 159.183. Native plants are strongly supported by City Forestry and the Tree Board. Under Indiana DNR's Terrestrial Plant Rule (312 IAC 18-3-25, effective April 18, 2019), 44 invasive plant species are designated pests and are prohibited from sale, gift, barter, exchange, distribution, transport, or introduction anywhere in Indiana — including in Noblesville landscapes.

Some RestrictionsArtificial Turf
Noblesville's UDC and Code of Ordinances contain no explicit ban on, nor minimum or maximum coverage limit for, artificial or synthetic turf in residential yards. UDC § 159.186 (Landscape Buffer Yards) specifies that areas in regulated buffer yards 'not planted with trees or shrubs shall be maintained as turf or other groundcover approved by the Director of Planning and Development' — meaning the Director has discretion to approve artificial turf as ground cover in non-residential landscape buffer applications. Residential homeowners installing synthetic lawn on private property do not need a City permit. HOA covenants may impose additional restrictions.
