How it works

From idea to certificate of occupancy

ADUs involve zoning review, architectural drawings, engineering, multiple permit departments, and a final CO inspection. We manage the entire process under one contract — you don't project-manage it.

01

Feasibility & vision

We review your lot, zoning, setbacks, utility connections, and HOA restrictions before you spend a dollar on drawings. We tell you what's buildable before anyone gets excited about floor plans.

02

Design & permit

Architectural drawings, structural engineering, and permit submission. We manage the back-and-forth with the Building Division, Zoning, and any required HOA approvals. Permit fees included in written scope.

03

Construction

Foundation, framing, roofing, electrical, plumbing, insulation, drywall, flooring, kitchen or kitchenette, bathroom — all trades coordinated under our GC license.

04

CO & handoff

Final inspections across all trades, CO issued by the county. You receive a completed, legal dwelling unit with a certificate of occupancy — ready to rent or move family in.

What we build in Palm Beach County

ADU types — from garage conversion to detached build

Garage conversions are the fastest and most cost-effective ADU option in Palm Beach County. Detached ADUs on large lots offer more flexibility and rental income potential. We build both.

Garage conversion

Convert your existing attached or detached garage into a legal, permitted living space. We handle the floor leveling, insulation upgrade, mini-split HVAC, electrical panel sub-feed, plumbing rough-in for a kitchenette and bathroom, and CO application. Most efficient ADU path in Palm Beach County.

Attached or detachedKitchenetteFull bathroomMini-splitCO included

Detached ADU

A standalone dwelling unit built on your lot — separate from the main house. New foundation, full mechanical systems, its own utility connections, kitchen, bathroom, and CO. Best option for maximizing rental income or creating a fully independent living space for family.

Palm Beach County · What property owners need to know

Why ADU permitting in Palm Beach County requires a licensed GC

Palm Beach County's ADU rules live in the Unified Land Development Code's Accessory and Temporary Uses chapter — and the coastal wind code, municipal patchwork, and HOA density here each add real cost and risk a handyman isn't equipped to manage.

Chapter 94: 800 Sq Ft Cap, Owner-Occupancy Required

West Palm Beach regulates accessory apartments under Chapter 94 of its own Zoning and Land Development Regulations — separate from the county's ULDC. Units are capped at 800 sq ft or 40% of the principal dwelling, whichever is less, and either the main house or the ADU must be owner-occupied. Eligibility and lot-width thresholds vary by single-family district. We confirm your district's standards before any design work begins.

Wind-Borne Debris Region, Up to 175 mph

Palm Beach County sits just north of Florida's High-Velocity Hurricane Zone but still falls in the Wind-Borne Debris Region, with ultimate design wind speeds reaching roughly 165–175 mph near the coast and tapering inland. Impact-rated windows, doors, and garage doors — or engineered shutters — are required by code, not a luxury upgrade. We size the correct product rating to your exact parcel, not a blanket spec.

Reviewed by the City, Not the County

West Palm Beach updated its ADU ordinance in 2022 and runs its own Planning Division review, separate from unincorporated Palm Beach County — minimum lot width (60 ft in SF14, for example) and setbacks (25 ft front, 7.5 ft side, 20 ft rear in SF14) vary by single-family district within the city itself. We confirm your specific district's standards before design begins, not after.

Sewer Tap Fees: $3,000–$12,000

Detached ADUs need a new electrical sub-panel or meter, a water connection, and a sewer tap — and in Palm Beach County that tap fee runs $3,000–$12,000 depending on municipality, on top of $5,000–$18,000 in impact fees for a new detached unit. We put both numbers in your written scope before you sign.

No CO, No Legal Rental

An unpermitted "in-law suite" can't be legally rented, has no standing at resale, and can jeopardize your homeowner's insurance. We build every Palm Beach County ADU toward a certificate of occupancy at close-out — the permit timeline is ours to manage, and the project isn't done until the CO is in your hands.

One Contract, Soup to Nuts

ULDC review, wind-rated product specs, permit submittal, trade coordination, and the CO — all under one contract with one point of contact, instead of a separate architect, engineer, plumber, electrician, and framer you sourced yourself. That's the design-build advantage, built on our track record in this county since 2019.

What ADU builders navigate in West Palm Beach

We have been navigating ADU permitting in Palm Beach County since 2019, including West Palm Beach's Chapter 94 code. Here is what shapes every project in this city.

Chapter 94 Requirements

  • Accessory apartments allowed in most single-family districts
  • Size capped at 800 sq ft or 40% of the principal dwelling, whichever is less
  • Owner occupancy required (main house or ADU)
  • SF14 district example: 60 ft min lot width, 25/7.5/20 ft setbacks
  • Reviewed by the Planning Division, (561) 822-1435

Typical Timeline

  • Feasibility + zoning review: 1–2 weeks
  • Architectural drawings + engineering: 4–8 weeks
  • Permit submission and review: 4–12 weeks (varies by jurisdiction)
  • Construction — garage conversion: 8–14 weeks
  • Construction — detached ADU: 16–28 weeks
  • Final inspections + CO: 1–3 weeks after construction complete

Cost Variables to Know

  • Sewer tap fees: $3,000–$12,000 depending on municipality
  • Impact fees: $5,000–$18,000 for new detached ADU in Palm Beach County
  • Architectural drawings: $4,000–$12,000 (included in our scope)
  • Structural engineering: $2,000–$6,000 (included in our scope)
  • Permit fees: $1,500–$6,000 (included in our scope)

Common Use Cases

  • Rental income unit — single-family neighborhoods in El Cid and Flamingo Park
  • In-law or family suite — Southland Park and Grandview Heights primary homes
  • Home office + guest space combo — Northwood and SoSo
  • Pool house conversion to legal dwelling — waterfront properties near Flagler Drive

West Palm Beach's biggest trap isn't the building code — it's owner-occupancy. Because Chapter 94 requires either the main house or the ADU to be owner-occupied, the first question on every West Palm Beach inquiry is whether the property qualifies as a primary residence, not what the unit will cost. We run that check in week one, before a single drawing is started.

Once eligibility clears, the coastal wind code sets the material budget. Impact-rated openings are code-required at 165–175 mph near the water, and the 800 sq ft / 40% cap means the floor plan has to work hard within a tight footprint. We price the real number against your specific parcel before you sign anything.

What property owners say about our ADU work

Verified reviews from ADU and garage conversion projects across our home market.

★★★★★

"Dariceli told us upfront that our HOA would need to approve before any drawings were started. We got approval first, then permitted, then built. CO in hand 7 months after we first called. The process was exactly what she described."

"Garage conversion in Lake Worth. D&Co handled the drawings, the permit, all the trades, and the CO. My son moved in within 4 months. The biggest thing was knowing the full cost upfront — no surprises on impact fees or utility hookups."

FG

Frank G.

Lake Worth — Garage Conversion to ADU

★★★★★

"I rent the unit out for $2,100/month. The total project cost was $78,000. I had two other contractors tell me they 'couldn't guarantee a CO.' D&Co was the only one who built it into the contract. That mattered more than the price."
