Quick Answers About Palm Beach Gardens, FL ADUs
Market Context
Palm Beach Gardens has a median home value of $520,000. Adding an ADU typically increases that by 25% — approximately $130,000 in added equity. A 1-bedroom ADU in Palm Beach Gardens rents for approximately $2,244/month in the Palm Beach County rental market , yielding a 5% cap rate on the investment. Occupancy averages 83% in this market.
Top Palm Beach Gardens neighborhoods for ADU investment include Westwood Gardens, PGA National, Palm Beach Square (Gardens core), Woodbine, Lake Catherine. Older single-family lots, lower median price and proximity to PGA Blvd/commute corridors make it attractive for ADU rentals. High rental demand from resort/events and a large stock of single-family homes with buildable lots.
Permit Process
Permit applications are reviewed by the Building Division , with a plan check timeline of approximately 7 weeks. Permit fees in Palm Beach Gardens range from $12,857 to $16,619 depending on project scope. Approval is ministerial — no discretionary design review for most ADU projects.
Palm Beach Gardens properties within the Coastal Overlay Zone require a Coastal Development Permit (CDP) in addition to standard building permits. CDPs add 2–6 months to the permit timeline and require compliance with both local ordinances and applicable state coastal zone management standards.
Because most of the city sits under the state-mandated Coastal Construction Control Line review, your ADU plans need a separate Coastal Development Permit on top of the standard building permit — this typically tacks on 4-6 extra weeks and requires wind-load calculations from an engineer familiar with South Florida's 170+ mph design standards. Many homeowners also get tripped up by the Building Division's requirement that detached ADUs on lots near the Intracoastal or within older platted communities verify septic-to-sewer conversion status before permitting, since Seacoast Utility Authority connection fees and capacity approval can add weeks if your street hasn't been upgraded. On top of that, if your property falls under one of PBG's many mandatory HOAs (common in PGA National or Mirasol), you'll need written architectural approval before the city will even log your permit application.
"In my experience working PBG permits, that 7-week timeline and $225/sqft figure read like state-level averages rather than what I see quoted locally, so I'd call the Building Division and get two or three local contractor bids before penciling in a budget or move-in date; and since you're in the coastal overlay, don't forget the CDP review can tack on real time even after plan check clears."

Property Eligibility
Is My Palm Beach Gardens, FL Property Eligible for an ADU?
Palm Beach 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 Palm Beach Gardens under local zoning ordinances — Florida law (§163.31771) only encourages, but does not mandate, local ADU approval. No owner-occupancy requirement in Palm Beach Gardens — you can rent both units as investment properties. Review process and timelines are set by local ordinance — confirm the current process with the Building Division 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 Palm Beach Gardens's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 45% of Palm Beach 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.
Coastal Zone Properties
Properties within Palm Beach Gardens's Coastal Overlay Zone require a Coastal Development Permit (CDP) in addition to standard building permits. This adds 2–6 months to the timeline. Our drawings flag coastal requirements and meet both local and applicable state coastal zone management standards.
Always verify eligibility with Building Division before designing.

Palm Beach Gardens ADU Return Calculator — Built With 2026 Local Data
Pre-loaded with verified Palm Beach Gardens construction costs, median rental rates, and property value uplift data. Adjust the inputs to model your specific project.
Your Project
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.

Local Zoning Rules
2026 Palm Beach Gardens ADU Rules
Palm Beach Gardens's 2026 ADU ordinance caps new units at 1,500 sq ft and 36 ft of height — generous — enough room for a full 2-bedroom layout. Setbacks run wide — 7 ft side / 15 ft rear — which pushes the buildable envelope toward the center of the lot. 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 $12,857–$16,619 — among the higher permit costs we track, and plan check takes about 7 weeks at Building Division. Submit directly to the department online — link below.
