Quick Answers About Miami Gardens, FL ADUs
Market Context
Miami Gardens has a median home value of $336,000. Adding an ADU typically increases that by 25% — approximately $84,000 in added equity. A 1-bedroom ADU in Miami Gardens rents for approximately $1,475/month in the Miami-Dade County rental market , yielding a 5.8% cap rate on the investment. Occupancy averages 95% in this market.
Top Miami Gardens neighborhoods for ADU investment include Rolling Oaks, Country Club Estates, Crestview, Brentwood, Carol City North. Large lots and higher-priced single-family homes make detached ADUs feasible and rentable. Generous lot sizes and single-family character support detached ADUs that meet county lot-size rules.
Permit Process
Permit applications are reviewed by the City of Miami Gardens Building Services Department , with a plan check timeline of approximately 3 weeks. Permit fees in Miami Gardens range from $4,041 to $4,093 depending on project scope. Design review: Yes - in historic districts only
Because Miami-Dade County enforces the High Velocity Hurricane Zone code on top of the city's own review, your ADU plans need a Notice of Acceptance (NOA) or Miami-Dade Product Approval for every window, door, and roofing material you spec — generic manufacturer specs from a big-box store won't cut it and get kicked back at plan review. Miami Gardens also runs impact fee assessments through the county's system rather than a flat city fee, so homeowners are often surprised months in when the county's separate invoice shows up after city permit approval. Since STRs aren't allowed here, expect the plans examiner to specifically check that the ADU has no separate exterior entrance marketed as a rental unit, which can trigger extra scrutiny on your site plan if the layout looks rental-ready.
"In my experience with Miami Gardens permitting, that 3-week timeline and $260/sqft figure look like statewide estimates rather than local realities — I've rarely seen plan check move that fast once corrections come back on a first submittal, so budget more like 6-10 weeks and get quotes from contractors currently active in the city before locking a schedule. I'd also call the City of Miami Gardens Building Services Department directly to confirm current queue times, since a clean-looking dataset like this rarely accounts for the back-and-forth that adds real weeks to your project."

Property Eligibility
Is My Miami Gardens, FL Property Eligible for an ADU?
Miami Gardens homeowners are governed by local zoning ordinances — Florida law (§163.31771) only encourages, but does not mandate, local ADU approval. Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in Miami Gardens under local zoning ordinances — Florida law (§163.31771) only encourages, but does not mandate, local ADU approval. No owner-occupancy requirement in Miami Gardens — you can rent both units as investment properties. Review process and timelines are set by local ordinance — confirm the current process with the City of Miami Gardens Building Services Department before designing.
Multi-Family Property
Additional ADUs on multi-family and duplex lots may qualify under local zoning ordinances — Florida law (§163.31771) only encourages, but does not mandate, local ADU approval — the exact number and type allowed depends on Miami Gardens's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 33% of Miami Gardens homes are in an HOA. Florida Statute §720.3035 limits HOA control over certain interior changes but does not preempt CC&Rs that ban ADUs outright — Florida HOAs generally retain the ability to restrict ADUs through their covenants. Our drawings include HOA submission formatting.

Projected Returns
* Estimates only. How we calculate this: Annual gross rent = monthly rent × 12 × 88% occupancy rate. Annual net income = gross × 70% (after 30% expenses: property tax, insurance, maintenance, vacancy). Value added = median home value × 25% uplift (regional ADU comparables). Total return = net income × years + value added. Break-even = total build cost ÷ annual net income. Consult a licensed financial advisor before investing.

Miami Gardens ADU Market at a Glance
Local Zoning Rules
2026 Miami Gardens ADU Rules
Miami Gardens's 2026 ADU ordinance caps new units at 800 sq ft — on the tighter side, which narrows floor plan options. Setbacks run tight — 0 ft side / 0 ft rear — which leaves more of the lot buildable. Because of FL's statewide wind-load provisions (Florida Building Code wind design / High-Velocity Hurricane Zone rules), structural drawings for a detached ADU here need a licensed engineer's stamp — architectural sheets for a code-compliant unit under the size cap generally don't.
Permit fees run $4,041–$4,093 — in line with what most homeowners budget for permitting, and plan check takes about 3 weeks at City of Miami Gardens Building Services Department. Submit directly to the department online — link below.
| Regulation | Miami Gardens Allowance |
|---|---|
| Max ADU Size | 800 sq ft |
| Max Height | 16 ft (detached) |
| Side Setback | 0 ft |
| Rear Setback | 0 ft |
| Architect / Engineer Stamp | Required for structural — FL's statewide wind-load provisions (Florida Building Code wind design / High-Velocity Hurricane Zone rules) |
