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

ADU projects in Palm Beach County touch every trade and every permit department. The process takes months and requires coordination that a handyman or unlicensed contractor simply cannot legally perform.

Multiple Permit Types Required

An ADU typically requires a building permit, electrical permit, plumbing permit, and mechanical permit — all submitted and managed separately. Under a licensed GC permit, we pull all of these under one contract. The county inspects each trade separately. Without a GC managing this, homeowners end up coordinating 4+ separate contractor permits and inspections — and the CO doesn't issue until all of them close.

Zoning & Setback Rules Vary by City

ADU regulations in Palm Beach County vary significantly between unincorporated county land, Boca Raton, Delray Beach, West Palm Beach, Jupiter, and other municipalities. Minimum lot size, setbacks, max square footage, and utility connection requirements are all different. We research the specific rules for your parcel before we quote — not after you've already paid for drawings that don't meet code.

HOA Restrictions

Many Palm Beach County communities have HOA restrictions on ADU construction — including setbacks from property lines, exterior materials, roofline requirements, and sometimes outright prohibitions. We review your HOA documents and CC&Rs before any money is spent on design. Building without HOA approval is a covenant violation with real legal exposure.

Utility Connection Complexity

Detached ADUs require electrical service (new sub-panel or meter), water connection, and sewer tap. In Palm Beach County, sewer tap fees alone can run $3,000–$12,000 depending on municipality. We include a utility connection cost assessment in the written scope — not a rough estimate. You know what the sewer tap costs before you sign anything.

The CO is What Matters

The certificate of occupancy is what makes an ADU legal to rent or occupy. Unpermitted "in-law suites" have no legal standing and create serious liability when you sell or insure the property. Every ADU we build targets a CO at close-out. The permit timeline is managed by us, and we don't consider a project finished until the CO is in your hands.

One Contract, Soup to Nuts

We provide architectural drawings, manage the permit, coordinate all trades, and deliver the CO. You have one contract and one point of contact — not a separate architect, engineer, plumber, electrician, and framer you hired off Craigslist. That's the value of a design-build licensed GC for a project this complex.

What ADU builders navigate in Palm Beach County

We have been navigating ADU permitting in Palm Beach County since 2019. Here is what shapes every project in this county.

Zoning by Jurisdiction

  • Palm Beach County unincorporated: ADUs allowed on lots 7,500 sq ft+ with R-1 or larger zoning
  • City of Boca Raton: allows ADUs in R-1D zones; separate application process through city planning
  • City of Delray Beach: ADUs permitted; city-specific design standards apply
  • West Palm Beach: ADU ordinance updated 2022; streamlined in some zoning districts
  • Jupiter and Wellington: each has separate ADU ordinances — confirm before designing

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 Boynton Beach, Lake Worth, West Palm
  • In-law or family suite — Boca Raton and Delray Beach primary homes
  • Home office + guest space combo — Palm Beach Gardens and Jupiter
  • Pool house conversion to legal dwelling — waterfront properties in Singer Island and Juno Beach

The most common reason an ADU project stalls in Palm Beach County is a zoning or HOA issue discovered after the homeowner has already paid for drawings. We spend the first 1–2 weeks on feasibility — lot coverage, setbacks, minimum lot size, utility capacity, and HOA review — before anyone draws a line. That's not extra overhead; it's the difference between a project that happens and one that dies after $15,000 in sunk design costs.

Impact fees and utility connection costs are the other surprise that low estimates omit. A detached ADU in unincorporated Palm Beach County can trigger $8,000–$18,000 in impact fees and $4,000–$12,000 in sewer tap fees — costs that have nothing to do with construction and everything to do with municipal infrastructure. We identify every fee in writing before you sign. No surprises at permit issuance.

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."

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."
