The Right Order to Build an ADU in Delray Beach
Most people get this backwards. Here's the order that saves time, money, and frustration.
Check your property eligibility — free, do this first
Not every Delray Beach address qualifies for an ADU. ADUs are only permitted in zones R-1-AA, R-1-A, R-1 and others. Checking first costs nothing and takes 60 seconds.

What ADU Builders in Delray Beach Won't Always Tell You
These are facts that directly affect your investment decision — and they're not always front-of-mind in a sales conversation.
Zoning eligibility: In Delray Beach, ADUs are only permitted in R-1-AA, R-1-A, R-1, RL zones — not every property qualifies. Verify your address before investing in design or engineering.
Maximum ADU size is 1,000 sq ft — some builders quote for larger units that will not pass Delray Beach's plan review. If a design exceeds this, it cannot be permitted.
Owner occupancy is not required — you can rent out both the main home and the ADU simultaneously, which improves your investment return.
Permit timeline: Standard: plan review 4–6 weeks, inspections 6–10 weeks, total 4–6 months. Historic district: add 4–8 weeks for HPB review. — any builder promising significantly faster delivery is either skipping steps or hasn't pulled a Delray Beach ADU permit recently.
Short-term rentals are permitted. Verify current Delray Beach rules and obtain required DBPR Vacation Rental Dwelling license if applicable.

Check My Delray Beach PropertyHow to Choose an ADU Builder in Delray Beach
Five criteria that separate experienced Delray Beach ADU builders from general contractors who've never pulled an ADU permit in this city.
Florida licensed and insured
Verify an active Florida Certified General Contractor (CGC) or Registered Building Contractor license at myfloridalicense.com. Never hire a contractor who cannot provide a license number upfront.
Experience with Delray Beach permits specifically
Ask for permit numbers from completed Delray Beach ADU projects. You can verify pulled permits directly at mydelraybeach.com. A builder who has never navigated local plan review will learn on your project.
Fixed-price contract, not time-and-materials
ADU projects with time-and-materials contracts routinely run 20–40% over initial estimates. A fixed-price contract with clearly defined scope transfers cost risk to the builder where it belongs. If a builder refuses fixed-price, ask why before proceeding.
References from completed Delray Beach ADU projects
Request three references from homeowners whose Delray Beach ADU projects reached Certificate of Occupancy within the last 24 months. Ask each reference specifically about permit timeline accuracy and how the builder handled unexpected issues.
Realistic timeline quotes
The actual Delray Beach permit timeline is: Standard: plan review 4–6 weeks, inspections 6–10 weeks, total 4–6 months. Historic district: add 4–8 weeks for HPB review.. Any builder quoting significantly faster has either not pulled a permit here recently or is not accounting for plan review cycles. Build the real timeline into your planning.
What Does an ADU Actually Cost in Delray Beach?
Total project cost has four components. Quotes that only cover construction will leave you underprepared.
Design & Engineering
Architectural drawings, structural engineering, and title 24 energy compliance. Typically $5,000–$15,000 depending on complexity and designer experience.
Permits & Fees
Delray Beach permit costs typically run $9,300–$17,950 in permits and fees (excluding construction). Impact fees: Palm Beach County impact fees apply; coastal HVHZ premium.
Construction
In Delray Beach: $110,000–$230,000 for 600–1,000 sq ft ADU (HVHZ coastal zone). Detached ADUs cost more than attached or garage conversions. Get a minimum of three bids.
Utility Connections
Electrical panel upgrades, water/sewer lateral connections, and gas lines if applicable. Often underquoted. Budget $5,000–$20,000 depending on existing infrastructure and distance from main home.
Rental income potential in Delray Beach: $1,500–$2,400/month per month. Run your numbers against total project cost — most Delray Beach ADUs break even within 8–12 years on long-term rental income alone.

Delray Beach ADU Builder — Frequently Asked Questions
Questions from Delray Beach homeowners who are getting ready to hire.
Do I need a builder to get a permit in Delray Beach?
No — in Florida you can apply for permits yourself as an owner-builder. However, most Delray Beach ADU permits involve structural, electrical, and plumbing work that legally requires licensed subcontractors. Most homeowners find a licensed general contractor manages the process more efficiently and reduces the risk of costly corrections.
How do I verify a contractor's license in Florida?
Use the Florida Department of Business & Professional Regulation (DBPR) license lookup at myfloridalicense.com. Search by contractor name or license number. Only hire contractors with an active Florida Certified or Registered license — never accept a contractor who cannot provide a license number.
What's the difference between a general contractor and an ADU specialist?
A general contractor holds the overall license and manages all trades. An ADU specialist is a general contractor (or design-build firm) who focuses specifically on accessory dwelling units and has completed multiple Delray Beach ADU permit cycles. They understand local plan review requirements, common rejection reasons, and realistic timelines — reducing surprises on your project.
Can I owner-build my ADU in Delray Beach?
Yes, Florida allows owner-builder permits for your own primary residence. You must personally supervise the work and cannot hire unlicensed contractors. Be aware that Delray Beach building departments scrutinize owner-builder applications carefully, and you remain personally liable for all code compliance. Most homeowners with no construction experience find that a licensed contractor pays for itself in avoided mistakes.
