Sioux Falls's Landscaping Rules: The Rules That Matter

Every city handles landscaping rules a little differently. In Sioux Falls, South Dakota, there are 9 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Native Plants

Sioux Falls encourages native prairie and pollinator landscaping. IPMC § 302.4 explicitly exempts cultivated flower beds, wildflower display gardens, and areas designated by the Parks and Recreation director as natural or native planting areas from the 8-inch height limit. The city sells subsidized Prairie and Pollinator Garden Kits in partnership with the Minnehaha Conservation District.

Key details: Native plantings exempt from 8" rule: Yes — IPMC § 302.4 wildflower/native-area exemption. City program: Prairie and Pollinator Garden Kit (with Minnehaha Conservation District). Front-yard living cover: 90% required (§ 160.485 Landscape Standards). Designating authority: Sioux Falls Parks and Recreation Director. Noxious-weed duty still applies: Yes — must control SDCL 38-22 species even in a native garden.

Code Enforcement may still cite a 'native garden' that is abandoned, overrun with state-listed noxious weeds, or indistinguishable from an unmown lot. Best practice is to maintain a defined edge, signage, and active stewardship to qualify under the wildflower-display or designated-natural-area exemption.

The rules around native plants in Sioux Falls lean permissive, but that does not mean anything goes.

Composting

Sioux Falls has no specific ordinance prohibiting residential backyard composting. Chapter 57 of the city code addresses yard waste through licensed haulers and the municipal landfill's free composting center, making backyard composting a permissive activity.

Key details: Backyard composting: Permitted (no specific ban). Nuisance rule: Chapter 93 applies if odors/vermin. Municipal compost center: Free at landfill. Yard waste pickup: Via licensed hauler (optional).

No specific composting penalties exist. Compost piles creating nuisances (odors, vermin, unsanitary conditions) may be cited under Chapter 93 Nuisances, with notice and fines up to several hundred dollars.

If you are coming from a city with tighter rules, you will find Sioux Falls gives residents more flexibility on composting.

Tree Removal & Heritage Trees

Private tree removal on residential property in Sioux Falls generally does not require a permit. However, boulevard trees between the sidewalk and street are city property and require approval from Urban Forestry before removal. Dead or hazardous trees must be removed by the property owner.

Key details: Private Trees: No permit generally required. Boulevard Trees: City approval required for removal. Replacement: May be required for boulevard trees. Contact: Parks & Rec Urban Forestry division.

Unauthorized removal: $500 to $10,000 per tree. Replacement planting required. Street tree damage: city restitution costs.

Weed Ordinances

Sioux Falls enforces both the city's 8-inch grass/weed limit (IPMC § 302.4) and the South Dakota statewide noxious-weed list adopted under SDCL Chapter 38-22. The eight statewide noxious species — Canada thistle, leafy spurge, purple loosestrife, hoary cress, perennial sow thistle, salt cedar, absinth wormwood, and gypsy moth — must be actively suppressed by every property owner regardless of height.

Key details: State weed law: SDCL Chapter 38-22. Statewide noxious species: Canada thistle, leafy spurge, purple loosestrife, hoary cress, perennial sow thistle, salt cedar, absinth wormwood, gypsy moth. City height limit: 8 inches (IPMC § 302.4). Lien authority: Yes — county board may assess abatement costs as tax lien (SDCL 38-22). Enforcement partners: Sioux Falls Code Enforcement + Minnehaha/Lincoln County Weed and Pest Boards.

City over-height grass: $100 citation plus abatement costs after the 7-day notice window. State noxious-weed non-compliance: county board may enter, treat, and assess the cost as a tax lien against the property under SDCL 38-22. Knowingly transporting noxious-weed seed or propagules can be a misdemeanor under Title 38.

Rainwater Harvesting

Rainwater harvesting is fully legal in South Dakota and actively encouraged by the City of Sioux Falls. There is no state water-rights restriction on rooftop collection, and the city's Water Conservation Division publishes a DIY 'Garbage Can into a Rain Barrel' guide. No permit is required for typical residential rain barrels.

Key details: Legal status: Fully legal — no state or city prohibition. Permit required: No, for typical residential rain barrels. State law: SDCL Title 46 (no rainwater-capture restriction). City stance: Encouraged; DIY guide published by Public Works. Backflow rule: Required for any potable cross-connection (Uniform Plumbing Code).

No specific rain-barrel violations exist in the code. Backflow or cross-connection failures that contaminate the city water supply can be cited under the city's water utility ordinances and Section 608 of the plumbing code. Mosquito-breeding standing water can trigger a public-health nuisance complaint under IPMC § 302.

Sioux Falls is more permissive than most cities when it comes to rainwater harvesting. That said, there are still limits.

Grass Height Limits

Sioux Falls Property Maintenance Code (IPMC 2021 as adopted) Section 302.4 caps non-woody plants on residential premises at 8 inches. Taller grass, lawn weeds, and rank vegetation are deemed nuisance vegetation enforced by the city's Code Enforcement division. Cultivated gardens, designated native/prairie planting areas, and crop or pasture land are exempt.

Key details: Height limit: 8 inches (non-woody plants). Code citation: Sioux Falls IPMC 2021 § 302.4 (locally amended). Citation amount: $100 plus abatement costs. Cure window: Approximately 7 days after notice (2 days after final publication). State noxious-weed backstop: SDCL Chapter 38-22.

After a notice is issued the property owner has a short cure window (per Section 302.4.1, two days after final publication of notice) to mow or remove the vegetation. Non-compliance triggers a $100 citation, plus the city may enter the property to cut, spray, or remove vegetation and bill the cost to the owner. Unpaid charges become a special assessment lien against the parcel under SDCL Chapter 9-32 nuisance-abatement authority.

Artificial Turf

Under Sioux Falls Code § 160.485 (Landscape Standards), artificial turf and artificial plantings cannot be used to satisfy the required minimum landscape standards, and at least 90% of the required front-yard setback in any zoning district must be living ground cover. Synthetic turf may be used as a supplemental ground cover in back/side yards or recreation areas, but not as the principal landscape material in a required setback.

Key details: Code citation: Sioux Falls Code § 160.485 (Landscape Standards). Front-yard living cover minimum: 90% of required setback. Artificial turf in required setbacks: Prohibited. Artificial turf in back/side yards: Allowed. Design guidance: Sioux Falls Landscape Design Manual (rev. March 2010).

Installing artificial turf in a required front-yard landscape setback can trigger a Code Enforcement notice under Title 51/Title 160, requiring removal and re-establishment of living ground cover. Commercial projects that fail landscape inspection cannot obtain a certificate of occupancy. Persistent violations may result in citations and abatement costs.

This is one of the stricter rules in Sioux Falls's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Tree Trimming

Chapter 94 (Forestry) makes the abutting property owner responsible for trimming, deadwooding, and maintaining street/boulevard trees in the parking strip. Section 94.038 requires a free Street Tree Planting Permit before planting any tree in the public right-of-way, and ash trees may not be trimmed, removed, or transported within the Minnehaha/Lincoln/Turner County emerald ash borer quarantine between Memorial Day and Labor Day.

Key details: Code citation: Sioux Falls Code of Ordinances Chapter 94 (Forestry); § 94.038 Planting in Public Rights-of-Way. ROW planting permit: Required, free, issued by City Forester. Setback from signals/signs: 20 feet. EAB ash-trimming blackout: Memorial Day through Labor Day. Quarantine counties: Minnehaha, Lincoln, Turner (SD DANR).

Forestry violations are typically handled through Code Enforcement notices under Title 51/Chapter 94, with abatement (city hires a contractor to perform necessary trimming) and costs billed to the owner. Unpermitted ROW planting may result in removal at the owner's expense. EAB-quarantine violations can also be prosecuted by SD DANR as a state misdemeanor.

Water Restrictions

Sioux Falls operates a permanent Stage 1 lawn-watering ordinance: no irrigation between noon and 5 p.m. any day, and lawns may only be watered on calendar dates matching the address parity (odd-address/odd-date, even-address/even-date). Stage 2 cuts watering to one day per week; Stage 3 prohibits all outdoor watering. Hand-watering of shrubs, trees, and gardens with a shut-off nozzle is allowed anytime.

Key details: Default stage: Stage 1 (year-round). Prohibited hours (Stage 1): 12:00 noon – 5:00 p.m. daily. Address rule: Odd address/odd date; even address/even date. Hand-watering: Allowed anytime with shut-off nozzle. First citation (Stage 2): $100.

Enforcement is complaint and patrol based. The city's stated policy is to issue warnings during Stage 1 and to escalate to $100 first-offense citations beginning in Stage 2, with higher penalties for repeat violations. The Public Works director may also disconnect service for chronic violators under utility ordinance authority.

The Bottom Line

Compared to many U.S. cities, Sioux Falls gives residents more room on landscaping rules. 3 of the 9 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

All of the above reflects Sioux Falls's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
