Quick Answers About Greenacres, FL ADUs
Market Context
Greenacres has a median home value of $340,000. Adding an ADU typically increases that by 28% — approximately $95,200 in added equity. A 1-bedroom ADU in Greenacres rents for approximately $1,575/month in the Palm Beach County rental market , yielding a 7.5% cap rate on the investment. Occupancy averages 91% in this market.
Top Greenacres neighborhoods for ADU investment include Historic Greenacres, Palm Beach Farms Co 3, Verona Estates, Catalina Estates, Lake Charleston. Highest-value neighborhood with large lots near downtown Greenacres, offering maximum equity to finance detached ADUs in a walkable core. Spacious 2,139–3,800 sq ft single-family homes on generous lots with strong rental demand from nearby Palm Beach State College and JFK Hospital commuters.
Permit Process
Permit applications are reviewed by the Greenacres Building Department . Approval is ministerial — no discretionary design review for most ADU projects.
Greenacres runs permit fees as a percentage of your total construction value rather than a flat fee, so a $368/sqft ADU build can trigger a much bigger permit bill than homeowners expect once they get their contractor's final estimate. Because Palm Beach County still handles utility connection approvals separately from city building review, homeowners often submit their Greenacres permit application only to get stuck waiting on a county sign-off for water/sewer capacity before the city will issue anything. It's worth calling the Utilities Department directly before finalizing your ADU square footage, since older lots in Greenacres sometimes have undersized service lines that need upgrading before a second dwelling unit can connect.
"In my experience, both the timeline and the per-square-foot cost shown here are blank or missing entirely for Greenacres, which tells me these are state-level placeholders rather than anything pulled from our local Building Department — I wouldn't build a budget or schedule around them. With 45% of the area under HOA control and STRs allowed, I'd get a written cost estimate from a local contractor and call the Building Department directly for current plan check queue times before you commit to numbers."

Property Eligibility
Is My Greenacres, FL Property Eligible for an ADU?
Greenacres 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 Greenacres under local zoning ordinances — Florida law (§163.31771) only encourages, but does not mandate, local ADU approval. No owner-occupancy requirement in Greenacres — you can rent both units as investment properties. Review process and timelines are set by local ordinance — confirm the current process with the Greenacres Building 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 Greenacres's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 45% of Greenacres 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.
Always verify eligibility with Greenacres Building Department before designing.

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 × 28% 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 Greenacres ADU Rules
Greenacres's 2026 ADU ordinance caps new units at 1,000 sq ft and 15 ft of height — in the typical range most ADU floor plans are designed around. Setbacks run 5 ft side and 5 ft rear, close to the regional baseline. 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 vary by project valuation — in line with what most homeowners budget for permitting through Greenacres Building Department. Submit directly to the department online — link below.
| Regulation | Greenacres Allowance |
