Palm Bay is the largest city in Brevard County — and like its neighbor Melbourne, it benefits from the Space Coast's booming aerospace and defense economy. SpaceX, NASA, L3Harris, and Northrop Grumman draw a high-income professional workforce that creates stable, year-round demand for well-appointed rental units. ADUs here are a sound investment — if your zoning qualifies.

Under Florida SB 184 (2025) and Palm Bay's zoning code, ADUs are generally permitted by right in single-family residential zones when code standards are met. The key exceptions: PUD (Planned Unit Development) properties need an ordinance-level confirmation, and owner occupancy is generally required in either the primary home or the ADU.

This guide covers everything: Palm Bay's zoning eligibility, the 800 sq ft / 50% dual size limit, setbacks, parking, the owner-occupancy affidavit, the ePermitHub permit process, Brevard County HVHZ wind load requirements, STR status, Space Coast rental data, and key contacts.

PUD properties — verify before proceeding

If your property is in a Planned Unit Development (PUD), your specific PUD ordinance may not automatically permit ADUs. Each PUD has its own governing document, and some restrict or prohibit accessory dwellings. Contact Palm Bay Growth Management with your address to confirm your PUD's ADU provisions before hiring anyone.

1. Palm Bay Zoning Districts & ADU Eligibility

Start with Growth Management

Contact Palm Bay's Growth Management office to verify your parcel's zoning district and ADU eligibility — especially if you believe your property might be in a PUD. Or use our address checker above to read live Brevard County GIS data on your parcel.

Palm Bay's single-family residential districts (SF, RS, and similar) generally permit ADUs by right when code standards are met. PUD districts require individual ordinance review. The 800 sq ft / 50% dual size limit is more restrictive than most Florida cities — understand it before you design.

The Dual Size Limit — How It Works in Palm Bay

800 sq ft OR 50% of primary dwelling area — the more restrictive controls

Palm Bay applies a dual size limit that is stricter than many Florida cities:

  1. Absolute maximum: 800 sq ft
  2. Relative maximum: 50% of the primary dwelling's living area

Whichever is smaller governs. Examples:

  • 2,000 sq ft primary dwelling → 50% = 1,000 sq ft → capped at 800 sq ft (absolute limit)
  • 1,400 sq ft primary dwelling → 50% = 700 sq ft → capped at 700 sq ft (relative limit)
  • 1,000 sq ft primary dwelling → 50% = 500 sq ft → capped at 500 sq ft

Minimum legal size: approximately 200 sq ft for a qualifying independent dwelling unit.

Verify your primary dwelling's living area at the Brevard County Property Appraiser (bcpao.us) before designing.

ADU Eligibility Standards

ADU Types Allowed: Detached backyard cottage, attached ADU, interior conversion — all generally permitted in eligible single-family zones. Verify with Growth Management for your specific district
Max ADU Size: 800 sq ft OR 50% of primary dwelling living area — whichever is LESS. More restrictive than most Florida cities
Minimum ADU Size: Approximately 200 sq ft for a legal independent dwelling unit
Rear Setback: Approximately 10 ft — verify with Growth Management for your specific parcel
Side Setback: Approximately 6 ft — verify with Growth Management
Structure Separation: Approximately 5 ft separation from other on-site structures
Height: Typically 25 ft or the height of the principal structure, whichever is less
Parking: 1–2 additional off-street spaces required for the ADU — verify current parking standard with Growth Management
Owner Occupancy: Generally required — owner must occupy either the primary dwelling or the ADU. Affidavit/attestation required in the permit workflow
PUD Properties: Must confirm via ordinance-level review — some PUDs do not auto-permit ADUs
STR: Not broadly banned by city ADU text — must comply with state licensing/tax requirements and any evolving local rules. Verify with Growth Management

HVHZ — Wind Load Requirements Add Cost

Palm Bay is in Brevard County, which carries High Velocity Hurricane Zone (HVHZ) wind load requirements under the Florida Building Code. All new construction must use impact-rated windows and doors, reinforced roof systems, and appropriate structural engineering. This adds cost — typically $5,000–$15,000+ compared to interior Florida counties. Build this into your budget before finalizing your project scope.

2. The 9-Step ePermitHub Permit Process

Palm Bay permit applications flow through ePermitHub (the City's online portal) or can be submitted in person at the Growth Management office. By-right ADUs do not require a special hearing — the process is administrative.

1

Growth Management Zoning Check — Critical for PUD Properties

Before spending money on surveys or plans, contact Palm Bay Growth Management to confirm your parcel's zoning and ADU eligibility. If your property is in a PUD, ask specifically whether your PUD ordinance permits ADUs. This single call prevents the most expensive mistakes in Palm Bay ADU projects.

2

Confirm the 800 Sq Ft / 50% Size Limit

Pull your primary home's living area from the Brevard County Property Appraiser at bcpao.us. Calculate 50% of that number and compare it to 800 sq ft — use whichever is smaller as your ADU's maximum size. Design starts here.

3

Verify Setbacks, Lot Coverage, and Parking Requirements

Confirm dimensional standards with Growth Management: rear setback (~10 ft), side setback (~6 ft), structure separation (~5 ft), height limit (25 ft or height of principal structure), lot coverage maximum, and the number of additional off-street parking spaces required (typically 1–2). Setback details vary by zoning district and lot dimensions.

4

Hire a Florida-Licensed Designer — Include HVHZ Expertise

Hire a Florida-licensed architect or designer to prepare signed and sealed construction drawings. Ensure your designer understands Brevard County's High Velocity Hurricane Zone (HVHZ) wind load requirements — impact windows, doors, and reinforced roof systems are required. Budget $3,000–$8,000+ for design, plus the HVHZ compliance premium.

5

Prepare a Complete Construction Package

Assemble all documents before submitting: property survey (signed and sealed), site plan with setback dimensions and parking, floor plans, building elevations, foundation and structural plans (HVHZ compliant), electrical/plumbing/mechanical plans, and energy compliance calculations (RESCHECK). Incomplete packages cause review delays.

6

Submit via ePermitHub or In-Person

Submit your complete permit package through ePermitHub (Palm Bay's online permit portal) or in person at the Growth Management office. ePermitHub allows online submission and permit status tracking. Create an account at the City's permit portal before applying.

7

Multi-Department Review

Palm Bay's review involves Building, Planning/Zoning, Fire, and Utilities departments. By-right ADU projects do not require a special hearing. Respond promptly to review comments — each round of comments adds time. Pay all permit fees and Brevard County impact fees upon permit issuance.

8

Construction and Inspections

Build per approved plans. Schedule required inspections via ePermitHub: footings/foundation, framing, rough electrical/plumbing/mechanical, insulation, and final. All construction must comply with Florida Building Code HVHZ wind load standards for Brevard County.

9

Certificate of Occupancy and Owner-Occupancy Affidavit

After passing final inspection, the City issues a Certificate of Occupancy. Do not occupy the ADU before CO. Submit the owner-occupancy affidavit — typically required as part of the permit workflow. Establish a separate address designation (e.g., 123 Main St, Unit B) and notify USPS.

3. Required Documents Checklist

6. Renting Your ADU — Space Coast Market

Palm Bay shares the same Space Coast employment base as Melbourne — SpaceX, NASA Kennedy Space Center, L3Harris, Northrop Grumman, and other defense/aerospace employers drive year-round professional rental demand. Palm Bay is the largest city in Brevard County and continues to grow as Space Coast employment expands.

Long-Term Rental Market

Studio ADU Estimate$900–$1,150/month (2025–2026 Palm Bay market)
1-Bedroom ADU Estimate$1,100–$1,450/month
Key Demand DriversSpaceX, NASA Kennedy Space Center, L3Harris, Northrop Grumman, Lockheed Martin — same Space Coast employers driving Melbourne's market
Vacancy RiskLow — Space Coast aerospace/defense economy in expansion; professional tenants sign multi-year leases
Seasonal StabilitySignificantly more stable than coastal tourist markets — STEM professional tenants dominate
Palm Bay vs. MelbournePalm Bay rents run slightly below Melbourne — larger geographic footprint, longer commutes to central Space Coast employers. Factor into your financial model.

Short-Term Rentals (Airbnb / VRBO)

🟢 STR Status — Not Broadly Prohibited (Verify Current Rules)

Palm Bay's ADU zoning text does not broadly ban short-term rentals in the way some Florida cities do. However, STR operations must comply with Florida state licensing requirements and any evolving local rules. Always verify current STR rules with Growth Management before building a financial model around STR income — rules can change. Owner occupancy is generally required, which limits pure-investment STR strategies.

Palm Bay STR StatusNot broadly banned in ADU code text — verify current local rules with Growth Management
Owner Occupancy ConstraintOwner must occupy primary or ADU — this limits pure-STR-investor strategies
State DBPR License (required statewide)All STRs in Florida require a Vacation Rental Dwelling license — apply at myfloridalicense.com
Brevard County Tourist Development Tax5% county TDT applies to all STR stays of 182 days or less — register at brevardcounty.us/TaxCollector
Florida State Sales Tax6% state sales tax applies to STR stays of 6 months or less — register at floridarevenue.com
HOA / Deed RestrictionsReview your CC&Rs — many Palm Bay HOAs restrict short-term rentals regardless of city rules

Long-Term Rental Logistics

Unit Address: Establish a separate mailing address designation (e.g., 123 Main St, Unit B) for legal rental purposes before CO.
Utility Metering: Contact Palm Bay Utilities about sub-metering or separate accounts. Option 1: Shared meter with tenant reimbursement. Option 2: Sub-meter (requires utility approval). Option 3: Separate accounts.
Owner-Occupancy Requirement: Palm Bay generally requires the owner to occupy either the primary dwelling or the ADU. This is confirmed via affidavit at the permit stage — understand this constraint before investing.
Florida Landlord-Tenant Law: Florida Statute Chapter 83 governs all residential tenancies: security deposits in separate FL bank account, 12-hour entry notice, no self-help evictions.

7. Common Pitfalls & How to Avoid Them

Not checking PUD status before hiring anyone

PUD properties in Palm Bay need ordinance-level confirmation that ADUs are permitted. Many PUDs have their own governing documents that restrict accessory units. Call Growth Management with your address — this 10-minute call prevents weeks of wasted work.

Misunderstanding the 800 sq ft / 50% size cap

Palm Bay's 50% relative cap is more restrictive than the 67% cap in cities like St. Pete. For a 1,200 sq ft home, you're capped at 600 sq ft — not 800 sq ft. Calculate 50% of your primary dwelling's living area before hiring a designer.

Underbudgeting for HVHZ wind load compliance

Brevard County's HVHZ requirements add meaningful cost — impact windows, reinforced roofing, structural engineering. Budget $5,000–$15,000+ above what an equivalent interior-county project would cost. Don't let this surprise appear late in design.

Not planning for the owner-occupancy requirement

Palm Bay generally requires the owner to live on the property (in either the primary home or the ADU). Pure-investment buyers who plan to rent both units may not qualify. Understand this constraint before purchasing a property specifically for ADU investment.

Submitting an incomplete ePermitHub package

Missing documents trigger review holds that add weeks. Prepare a complete construction package — survey, site plan, floor plans, elevations, structural drawings (HVHZ compliant), electrical/plumbing/mechanical, RESCHECK, and contractor license — before submitting.

Underestimating Brevard County impact fees

The county assesses transportation, school, parks, and fire impact fees on all new residential units. Budget $3,000–$8,000+ and get a written estimate before finalizing your construction budget.

Confusing Palm Bay with Melbourne or unincorporated Brevard County

These are different jurisdictions. Palm Bay, Melbourne, West Melbourne, and unincorporated Brevard County all have separate permit offices and potentially different standards. Confirm your property is within Palm Bay city limits.

HOA restrictions overriding city permits

City permits don't override HOA covenants. Many Palm Bay neighborhoods have HOA rules that restrict ADUs or short-term rentals. Review your CC&Rs with a real estate attorney before committing.

9. Frequently Asked Questions

Can I build an ADU in Palm Bay, Florida?

Yes, in most cases. Palm Bay generally allows ADUs in single-family residential zones by right when code standards are met. Important exception: if your property is in a PUD (Planned Unit Development), your specific PUD ordinance may not permit ADUs. Contact Growth Management to confirm your parcel's eligibility before proceeding.

What is the maximum ADU size in Palm Bay?

The maximum is 800 sq ft OR 50% of the primary dwelling's living area — whichever is LESS. This is more restrictive than many Florida cities. For a 1,400 sq ft home, the ADU cap is 700 sq ft (50%), not 800 sq ft. Verify your primary home's living area at bcpao.us before designing.

What are the setbacks for an ADU in Palm Bay?

Approximately 10 ft rear setback, 6 ft side setback, and 5 ft separation from other on-site structures. Height is typically 25 ft or the height of the principal structure, whichever is less. Verify exact setbacks with Growth Management for your specific parcel and zoning district.

Does Palm Bay require owner occupancy for an ADU?

Yes, generally. Palm Bay typically requires the property owner to occupy either the primary dwelling or the ADU. The permit workflow includes an owner-occupancy affidavit that must be submitted. Verify the current owner-occupancy requirement with Growth Management when applying.

How do I submit an ADU permit application in Palm Bay?

Palm Bay permit applications can be submitted through ePermitHub (the City's online portal) or in person at the Growth Management office. Start with a zoning verification check at Growth Management to confirm your parcel's eligibility before preparing your full construction package.

Are there HVHZ wind load requirements for ADUs in Palm Bay?

Yes. Palm Bay is in Brevard County, which has High Velocity Hurricane Zone (HVHZ) wind load requirements. All new construction must comply — including impact-rated windows and doors, reinforced roof systems, and appropriate structural engineering. Budget $5,000–$15,000+ above an equivalent interior-county project.

How much rental income can I earn from an ADU in Palm Bay?

Long-term ADU rents in Palm Bay typically run $1,100–$1,450/month for a 1-bedroom unit (2025–2026 data). The Space Coast aerospace and defense economy — SpaceX, NASA, L3Harris, Northrop Grumman — drives stable, year-round demand from STEM professionals. Vacancy risk is low compared to seasonal coastal markets.
