Melbourne's Space Coast economy — anchored by SpaceX, NASA Kennedy Space Center, Lockheed Martin, L3Harris, and Northrop Grumman — creates one of Florida's most stable markets for ADU rental income. The professional workforce is deep, rents are strong, and vacancy risk is low compared to seasonal coastal cities.
Under Florida SB 184 (2025) and HB 1339 (2023), Melbourne permits ADUs — called Second Dwelling Units — by right in all residential zoning districts. Detached, attached, garage conversion, and interior conversion are all permitted. What matters is your specific lot size, zoning district, and setbacks.
This guide covers everything: Melbourne's residential zoning districts, ADU eligibility requirements, the 10-step EnerGov permit process, Brevard County impact fees, Space Coast rental income data, short-term rental status, common pitfalls, and key contacts.
Verify your jurisdiction first
Melbourne, West Melbourne, Melbourne Beach, and unincorporated Brevard County are four separate jurisdictions with different zoning codes, STR rules, and permit offices. Check your exact city boundary using Melbourne's GIS map before proceeding.

1. Melbourne Zoning Districts & ADU Eligibility
Look up your zoning district first
Go to Melbourne's GIS map, search your address, and note your zoning district code (R-1A, R-2, PUD, etc.). Or call the Planner of the Day at (321) 608-7500.
Melbourne's residential districts run from large-lot rural to dense multifamily. Precise dimensional standards are in Tables 2a and 2b of Melbourne's Zoning Code (Appendix B, Article V) — always verify with city staff.
| Zone | District Type | Min Lot Area | ADU Permitted? |
|---|---|---|---|
| R-A | Agricultural/Rural Residential — very large lots | 1+ acre | Yes — by right (SB 184) |
| AEU | Agricultural Estate Unit — large-lot semi-rural | 1+ acre | Yes — by right |
| REU | Rural Estate Unit — estate-size lots | ~0.5–1 acre | Yes — by right |
| R-1AAA | Single-Family — largest suburban lots | ~15,000+ sq ft | Yes — verify with city |
| R-1AA | Single-Family — large suburban lots | ~10,000–12,000 sq ft | Yes — verify with city |
| R-1A | Single-Family — standard suburban lots | ~7,500–9,000 sq ft | Yes — verify with city |
| R-2 | Single and Two-Family — duplexes permitted | ~6,000–7,500 sq ft | Yes — by right |
| R-3 | Multifamily — up to ~12 du/acre | ~5,000+ sq ft | Yes — by right |
| R-4 | High-Density Multifamily | Varies | Yes — verify use standards |
| PUD | Planned Unit Development — custom rules | Per PUD plan | Contact city — PUD-specific |
⚠️ Lot area figures are approximate reference ranges. Melbourne's exact Table 2a/2b standards may differ — always verify with the Planner of the Day at (321) 608-7500 or at library.municode.com/fl/melbourne.
ADU Eligibility Requirements
Melbourne calls ADUs “Second Dwelling Units” and permits them under Florida's HB 1339 (2023) and SB 184 (2025). Key requirements:
📞 Call Before You Design
Melbourne's zoning code dimensional tables are complex and district-specific. Before paying an architect, call the Planner of the Day at (321) 608-7500 with your address. Confirm your lot size, zoning district, setback requirements, and max lot coverage. This 15-minute call can save thousands in redesign costs.
2. The 10-Step EnerGov Permit Process
Melbourne does not have a standalone ADU guide. All permits flow through the EnerGov portal. The process below reflects Melbourne's standard residential construction permit pathway.
Pre-Application: Call the Planner of the Day
Call (321) 608-7500 and confirm: your zoning district's ADU eligibility, precise setbacks and lot coverage limits, whether any overlays apply (historic, airport, flood zone), and whether a pre-application meeting is recommended for your project.
Register on EnerGov and Gather Property Records
Create an account at energovweb23.mlbfl.org. Obtain a current property survey (signed and sealed by a Florida-licensed land surveyor, typically dated within the past 5 years). Pull your property details from the Brevard County Property Appraiser at bcpao.us.
Hire a Florida-Licensed Design Professional
Melbourne does not offer free pre-approved ADU plans. You need a Florida-licensed architect or engineer to prepare signed and sealed construction drawings. Budget $3,000–$8,000+ for design fees. Ask your designer to review the Melbourne zoning code (Appendix B) and Florida Building Code 8th Edition (2023) before starting.
Consider the Florida Private Provider Program (Expedited Path)
You may hire a state-approved Private Provider firm to perform plan review and inspections independently of the city's queue. This typically cuts review time from months to weeks. Search for registered Private Providers at floridabuilding.org.
Submit Building Permit Application via EnerGov
Submit online at energovweb23.mlbfl.org. Required documents include: completed application, property survey, site plan with setback dimensions, floor plans, building elevations, structural drawings, energy compliance calculations (RESCHECK), and contractor license and insurance. Email BLDplanreview@mlbfl.org with questions.
Record Notice of Commencement (NOC)
Before starting construction, record a Notice of Commencement with the Brevard County Clerk of Courts at brevardclerk.us. This is a Florida legal requirement. Post a certified copy on-site throughout construction.
Plan Review and Permit Issuance
Melbourne Building Section reviews for zoning compliance and Florida Building Code compliance. Respond to any review comments promptly. Pay all fees upon permit issuance. Note: Brevard County also assesses its own impact fees (transportation, schools, parks, fire) for new residential units — contact the Brevard County Impact Fee Office at (321) 633-2000.
Required Outdoor Lighting Certification ⚠️ Easy to miss
Melbourne requires an Outdoor Lighting Certification Form for any new or replacement exterior luminaires — effective October 1, 2018. This is commonly missed and can delay final inspection. Confirm with Building Section at (321) 608-7900.
Construction and Inspections
Build per approved plans. Schedule inspections via EnerGov: footings/foundation, framing, rough electrical/plumbing/mechanical, insulation, final. Melbourne is in Brevard County's High Velocity Hurricane Zone (HVHZ) area — all construction must comply with Florida Building Code wind load requirements.
Certificate of Occupancy
After passing the final inspection, Melbourne issues a Certificate of Occupancy (CO). Do not occupy the ADU before the CO is issued. Establish a separate address designation for the unit (e.g., 123 Main St, Unit B) and notify USPS.

Historic Tax Credits (if applicable)
If your property is in a Melbourne historic district, certain rehabilitation tax credits may apply. Contact the Historic & Architectural Review Board at (321) 608-7500.
6. Renting Your ADU — Space Coast Market
Melbourne's Space Coast location gives ADU owners a compelling rental story. The area's professional workforce — driven by SpaceX, Blue Origin, Lockheed Martin, L3Harris, Northrop Grumman, and NASA — creates stable, year-round demand for well-appointed rental units that's far less seasonal than coastal tourist markets.
Long-Term Rental Market
| Studio ADU Estimate | $1,100–$1,350/month (2025–2026 Melbourne market) |
| 1-Bedroom ADU Estimate | $1,300–$1,503/month |
| Melbourne Market Average (1-bed) | $1,135–$1,503/month across sources (2025 data) |
| Key Demand Drivers | SpaceX, Blue Origin, Lockheed Martin, L3Harris, Northrop Grumman, NASA Kennedy Space Center (~12 miles north), Melbourne International Airport |
| Vacancy Risk | Low — Space Coast economy in expansion; defense/aerospace contracts drive stable multi-year employment; 40% renter-occupied households |
| Seasonal Stability | Significantly more stable than coastal tourist markets; professional tenants typically sign 12-month leases |
| Premium Zones | Eau Gallie Arts District, Melbourne beachside, and the Rockledge corridor to KSC command rent premiums |
Short-Term Rentals (Airbnb / VRBO)
🟢 STR Status — Currently Unregulated (Proceed With Awareness)
As of early 2026, the City of Melbourne does not have specific local ordinances governing short-term rentals in residential zones. STRs are neither explicitly permitted nor prohibited by city ordinance. This creates a relatively open environment — but the absence of regulation also means rules could change at any time.
| City of Melbourne STR Status | No specific local STR ordinance as of early 2026 — renting short-term is not explicitly prohibited in residential zones |
| West Melbourne (neighboring city) | Explicitly PROHIBITS short-term rentals under one week — do not confuse with City of Melbourne |
| Melbourne Beach (neighboring town) | Has its own STR rules based on zoning — do not confuse with City of Melbourne |
| State DBPR License (required statewide) | All STRs in Florida require a Vacation Rental Dwelling license — apply at myfloridalicense.com |
| Brevard County Tourist Development Tax | 5% county TDT applies to all STR stays of 182 days or less — register at brevardcounty.us/TaxCollector |
| Florida State Sales Tax | 6% state sales tax applies to STR stays of 6 months or less — register at floridarevenue.com |
| Airbnb Revenue Estimate | Brevard County Space Coast market typically generates $22,000–$35,000/year gross for a well-managed 1-bed ADU |
Monitor STR status
Follow Melbourne City Council agendas at melbourneflorida.org. STR regulation is an active topic in many Florida cities and could change on short notice. Build your financial model for long-term rental income as the baseline; treat STR income as upside, not a guarantee.

7. Common Pitfalls & How to Avoid Them
Not verifying jurisdiction first
Assuming your property is in Melbourne city limits when it may be in unincorporated Brevard County means you're applying to the wrong office with the wrong rules. Always verify using Melbourne's GIS map at mgis.maps.arcgis.com.
Confusing Melbourne with West Melbourne or Melbourne Beach
These are three entirely separate cities with different zoning codes and STR rules. Double-check which city your property is in before doing anything else.
Skipping the Planner of the Day call
Melbourne's zoning code tables are not easily accessible online. A 15-minute call to (321) 608-7500 gets you precise setbacks, lot coverage limits, and confirms ADU eligibility for your specific parcel — do this before hiring a designer.
Missing the Outdoor Lighting Certification Form
Every new or replaced exterior light fixture requires this form (effective 2018). Forgetting it delays final inspection.
Not recording the Notice of Commencement before construction
Florida law requires the NOC to be recorded with the Brevard County Clerk and posted on-site before construction begins. Skipping this creates lien law problems.
Underestimating Brevard County impact fees
The county assesses transportation, school, parks, and fire impact fees on all new residential units — including city-permitted ADUs. Budget $3,000–$8,000+ and get a written estimate before finalizing your construction budget.
Wind load compliance surprises
Brevard County's coastal exposure requires compliance with Florida Building Code High Velocity Hurricane Zone standards. Impact-rated windows, doors, and roof systems add cost — factor this in early.
Assuming STR status is permanent
Melbourne currently has no specific STR ordinance, but this can change quickly. Build your financial model for long-term rental income as the baseline; treat STR income as upside.
HOA restrictions
City permits don't override HOA covenants — review your CC&Rs before committing to plans.
Not establishing a separate unit address
Without a formal unit address, mail delivery, lease agreements, and utility accounts become unnecessarily complicated. Set this up before the CO.

Can I build an ADU in Melbourne, Florida?
Yes. Melbourne permits ADUs (called Second Dwelling Units) by right in all residential zoning districts under Florida HB 1339 (2023) and SB 184 (2025). All types are permitted — detached, attached, garage conversion, and interior conversion. Your lot must meet the minimum size for your zoning district and leave room for the ADU within required setbacks.
What are the setbacks for an ADU in Melbourne FL?
Typical Melbourne residential setbacks are approximately 25 ft front yard, 7.5–10 ft side yard, and 10–20 ft rear yard — but these vary by zoning district. When an ADU functions as a full Second Dwelling Unit, it must meet principal structure setbacks, not the looser accessory structure setbacks. Verify your exact setbacks in Melbourne's Zoning Code Tables 2a/2b at library.municode.com/fl/melbourne or call the Planner of the Day at (321) 608-7500.
How do I get an ADU permit in Melbourne FL?
All Melbourne building permits flow through the EnerGov portal at energovweb23.mlbfl.org. You need: a current property survey, construction drawings sealed by a Florida-licensed architect or engineer, a site plan, energy compliance calculations (RESCHECK), and a contractor license. Before submitting, call the Planner of the Day at (321) 608-7500. Budget 4–10 weeks for standard plan review, or 1–3 weeks via the Florida Private Provider expedited path.
What are Brevard County impact fees for an ADU in Melbourne?
Brevard County assesses impact fees on all new residential units regardless of whether the City of Melbourne or the county is doing the permitting. Fee types include transportation, schools, parks, and fire. Budget $3,000–$8,000+ depending on unit size and location. Contact the Brevard County Impact Fee Office at (321) 633-2000 for a project-specific estimate.
Can I do Airbnb or short-term rentals with my Melbourne ADU?
As of early 2026, the City of Melbourne does not have specific local ordinances governing short-term rentals in residential zones. However, you still need a Florida DBPR Vacation Rental Dwelling license and must collect and remit Brevard County's 5% Tourist Development Tax plus Florida's 6% state sales tax. Note: West Melbourne and Melbourne Beach are separate cities with different rules. Monitor Melbourne City Council agendas as STR rules could change.
How much rental income can I earn from an ADU in Melbourne FL?
Long-term ADU rents in Melbourne typically run $1,100–$1,500/month for a studio or 1-bedroom unit (2025–2026 data). The Space Coast aerospace economy drives stable, year-round demand from high-income STEM professionals. Short-term rental (Airbnb/VRBO) typically generates $22,000–$35,000/year gross for a well-managed 1-bedroom ADU in the Brevard County market.
Do I need to live on the property to build an ADU in Melbourne?
No. The City of Melbourne does not require owner-occupancy — both the primary home and the ADU may be rented. Verify that your property is within City of Melbourne limits (not unincorporated Brevard County, West Melbourne, or Melbourne Beach) as each has different rules.
