Dunedin's Landscaping Rules: The Rules That Matter

Every city handles landscaping rules a little differently. In Dunedin, Florida, 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.

Tree Removal & Heritage Trees

Dunedin requires a $25 tree removal permit for any protected tree, defined as a shade tree 4 inches DBH or larger. Removal triggers replacement requirements of one or two trees depending on size.

Key details: Permit fee: $25 per application. Protected size: 4 inches DBH shade trees. Reviewing body: Parks Division arborist. Replacement small: 1 tree under 19 inches. Replacement large: 2 trees 19 inches plus.

Unpermitted removal can trigger fines, mitigation planting orders proportional to canopy lost, and stop-work orders on related construction permits.

Compared to other cities, Dunedin takes a harder line on tree removal & heritage trees. The enforcement and penalty structure reflects that.

Tree Trimming

Dunedin allows routine maintenance trimming of most protected trees without a permit, but Grand Trees and any pruning that removes over 25 percent of canopy require permits and an Approved Arborist.

Key details: Permit threshold: Over 25% canopy removal. Grand Tree size: 30 inches DBH and above. Grand Tree work: Requires Approved Arborist. Topping: Prohibited without permit. Code section: Chapter 105, Division 3.

Citations for excessive pruning, replacement-tree mandates, daily fines, and liability for removal if pruning causes the tree to die.

Native Plants

Dunedin actively promotes Florida-Friendly Landscaping with native plants. State law preempts HOA bans on Florida-Friendly designs, and the city's tree code references native species lists for replacement plantings and required plantings.

Key details: State protection: FS 373.185 FFL statute. City list: Pre-Approved Tree List. HOA limit: Cannot ban FFL designs. Code reference: Chapter 105 standards. Local program: Dunedin Green Scene.

Few code conflicts arise; HOA enforcement attempts may be challenged under Sec. 373.185 with prevailing-party fee shifting.

If you are coming from a city with tighter rules, you will find Dunedin gives residents more flexibility on native plants.

Composting

Dunedin actively promotes residential composting through its Dunedin Does Compost program offering 82-gallon bins. Backyard compost piles are allowed but must be maintained to avoid Chapter 34 nuisance citations for odors or vermin.

Key details: City program: Dunedin Does Compost. Bin size: 82-gallon stationary. Restrictions: No meat, dairy, pet waste. Nuisance code: Chapter 34 enforcement. Curbside option: Weekly yard-waste pickup.

Code enforcement under Chapter 34 nuisance provisions for odors, rodents, or oversized piles. Daily fines and abatement orders apply if not corrected.

Dunedin is more permissive than most cities when it comes to composting. That said, there are still limits.

Rainwater Harvesting

Rainwater harvesting is legal and encouraged in Dunedin. The city and SWFWMD promote rain barrels as a conservation tool, and there are no Dunedin-specific prohibitions, though structural cisterns may require building permits.

Key details: Permit needed: Plumbed or large cisterns. Small barrels: Generally no permit. Inlet rule: Debris screen required. Overflow: Must be properly sized. HOA protection: FFL statute applies.

Permits violations for unpermitted plumbed cisterns; possible cross-connection citations from Dunedin Utilities for unprotected potable connections.

If you are coming from a city with tighter rules, you will find Dunedin gives residents more flexibility on rainwater harvesting.

Weed Ordinances

Dunedin treats overgrown weeds, brush, and rank vegetation as public nuisances under Chapter 34. Property owners must routinely clear weed growth to avoid notices, daily fines, and city-performed abatement billed back as a lien.

Key details: Threshold: Around 10 inches. Code chapter: Chapter 34 environment. Cure window: Typically 7 to 10 days. Abatement: City mows and liens. Hearings: Special magistrate process.

Notice of violation with cure period; daily fines, city abatement and mowing fees, and recorded liens for unpaid assessments.

This is not one of those rules that cities tend to ignore. Dunedin actively enforces its weed ordinances requirements.

Grass Height Limits

Dunedin enforces a strict 10-inch maximum grass height under Chapter 34. The city is well-known nationally after a homeowner faced roughly $30,000 in fines for overgrown turf, demonstrating aggressive code-enforcement practices.

Key details: Max grass height: Around 10 inches. Code chapter: Chapter 34, environment. Enforcement: Daily accruing fines. Notable case: $30,000 lawn fine. Abatement: City mows and liens lot.

First-time mailed notice with cure period; subsequent daily fines, city-performed mowing billed back to owner, and recorded liens on title.

Compared to other cities, Dunedin takes a harder line on grass height limits. The enforcement and penalty structure reflects that.

Water Restrictions

Dunedin follows Southwest Florida Water Management District schedules. Under the current Modified Phase III shortage, irrigation is limited to one assigned day per week between 12:01-4:00 AM, with $500 maximum citations and no first-warning period.

Key details: Current phase: Modified Phase III. Frequency: One day per week. Allowed hours: 12:01-4:00 AM. Maximum fine: $500 per violation. Authority: SWFWMD adopted locally.

Immediate citations starting April 17, 2026, no warning notices, civil penalties up to $500 per occurrence, and possible utility service action.

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

Artificial Turf

Florida law preempts city bans on synthetic turf for single-family residential lots one acre or smaller. Dunedin must allow artificial grass meeting state-defined material standards, though setback and stormwater rules still apply.

Key details: Preemption: Lots 1 acre or smaller. Material rule: Lead free, flame retardant. Infill ban: No rubber infill. Authority retained: Stormwater and setbacks. Effective: Florida HB 1191 2024.

Code enforcement for substandard installations, drainage violations, prohibited rubber infill, or installation on parcels above one acre without approval.

The rules around artificial turf in Dunedin lean permissive, but that does not mean anything goes.

The Bottom Line

Dunedin's landscaping rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Dunedin is broadly strict or permissive.

Keep in mind that Dunedin can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
