AfterHow Much Does ADU Construction Cost in Pompano Beach?
ADU construction in Pompano Beach, FL typically runs between $90,000 and $220,000 depending on size, type, and finish level. A detached 600-square-foot guest cottage lands in the middle of that range; a fully permitted two-story unit with a separate entrance and impact-rated windows sits at the top. Most Pompano Beach homeowners we work with budget $130,000 to $160,000 for a livable, code-compliant unit that earns rental income from day one.

ADU Construction Cost Breakdown (2026)
The table below reflects actual line-item costs in the Pompano Beach market as of 2026. Every number here is what our written quotes show, not a national average pulled from a spreadsheet.
| Cost Category | Typical Range (Pompano Beach) | Notes |
|---|---|---|
| Site prep and foundation | $8,000 - $22,000 | Slab-on-grade is most common here; high water table in east Pompano can add cost |
| Framing and structural | $15,000 - $35,000 | CBS (concrete block) vs. wood frame affects price; Broward County wind-load code applies |
| Roofing | $8,000 - $20,000 | Flat and low-slope roofs common on ADUs in Pompano Beach; tile and metal add cost |
| Impact windows and doors | $8,000 - $25,000 | Required under Florida Building Code for new construction in Broward County |
| Plumbing (rough-in and finish) | $8,000 - $18,000 | Connection distance to main house utilities drives the low or high end |
| Electrical (rough-in, panel, and finish) | $6,000 - $14,000 | Separate meter adds $2,000 - $4,000; many Pompano Beach rental ADUs opt for this |
| HVAC (mini-split system) | $3,500 - $9,000 | Mini-splits dominate ADU installs in South Florida for efficiency and zoning flexibility |
| Insulation and drywall | $4,000 - $9,000 | Spray foam at the roof deck is worth the cost in Pompano Beach’s heat and humidity |
| Kitchen (basic to mid-grade) | $9,000 - $20,000 | Small kitchen remodel range; KraftMaid or Wellborn cabinets are typical here |
| Bathroom (one full bath) | $9,000 - $28,000 | Kohler or Toto fixtures with a tiled walk-in shower land mid-range |
| Flooring | $3,500 - $9,000 | Porcelain tile and luxury vinyl plank are the practical choices for South Florida humidity |
| Interior finishes (trim, paint, hardware) | $3,000 - $7,000 | Finish level here affects perceived rental value more than any single line item |
| Permits and inspections | $3,000 - $8,000 | City of Pompano Beach permit fees are calculated on valuation; budget above the minimum |
| Architecture, engineering, and surveys | $4,000 - $12,000 | Broward County requires signed-and-sealed drawings for all new residential structures |
| Contingency (recommended) | 10% - 15% of total | Soil conditions and utility routing surprises are the most common source of overages here |
What the Total Actually Looks Like
Add those ranges up and you land at $90,000 on the low end for a stripped-down, owner-finish detached unit of around 400 square feet, and $220,000 on the high end for a 900-square-foot two-bedroom with full kitchen, Caesarstone countertops, Kohler fixtures throughout, impact-rated windows, a separate electrical meter, and spray-foam insulation. The majority of our ADU Construction in Pompano Beach projects land between $130,000 and $165,000 – that’s a 500-to-650-square-foot one-bedroom unit finished to a standard that commands market rent.
Garage conversions are a separate calculation. Converting an existing attached garage in Pompano Beach typically runs $30,000 to $80,000 because the structure already exists – you’re adding insulation, HVAC, plumbing, and finishes rather than building a shell from scratch. That’s a meaningful cost difference, though the permit process is still the same.
Under Clause 1 of the Haven Standard, every Rowan project receives a written price and written scope before anyone starts work. No change proceeds without a signed change order. That discipline is why our projects close within a few percent of the number the customer agreed to – across more than 4,000 jobs since 2007.

What Affects ADU Construction Pricing in Pompano Beach
Six factors move the number in Pompano Beach more than anything else. Some are about the unit itself; some are about the lot and the code environment here specifically.
-
ADU type: detached new construction vs. garage conversion vs. attached addition.
A detached unit costs more than a garage conversion because you’re building a complete structure from foundation to roof. An attached ADU – essentially a home addition with a separate entrance – sits between the two. In Pompano Beach neighborhoods like Collier City and Cresthaven, where lots are wider, detached ADUs are common. In denser east Pompano blocks closer to the beach, garage conversions or interior conversions are often the only practical option. -
Broward County wind-load and Florida Building Code requirements.
Pompano Beach falls in the High-Velocity Hurricane Zone (HVHZ), which means every new structure must meet FBC Section 1609 wind-load requirements. This applies to the roof decking fastening schedule, wall framing, and most importantly, windows and doors – impact-rated glazing is not optional here. Budget $8,000 to $25,000 for impact windows and exterior doors alone. Contractors who quote below this range for a full ADU build are typically not pricing code-compliant work. -
Lot conditions and utility routing distance.
Pompano Beach’s east side has a notably high water table. On lots near the Intracoastal or in lower-lying areas of the Cypress Pointe neighborhood, slab preparation may require additional fill, compaction, or drainage work before the concrete is poured. Plumbing and electrical routing distance from the main house to the ADU is the other variable: a unit 20 feet from the main house costs less to connect than one at the back of a 150-foot-deep lot. -
Size and square footage.
This is the most straightforward driver. Florida allows ADUs up to 1,200 square feet or 50% of the primary dwelling’s footprint, whichever is less. A 400-square-foot studio costs fundamentally less than an 800-square-foot two-bedroom, not just in materials but in permit valuation, architectural drawings, and time on site. Per-square-foot costs in Pompano Beach generally run $160 to $250 per square foot for a code-compliant turnkey ADU build, depending on finish level. -
Kitchen and bathroom finish level.
The ADU kitchen is a small kitchen by any measure – typically 80 to 140 square feet. But finish choices still move the needle. KraftMaid semi-custom cabinets with Caesarstone countertops in a 100-square-foot galley kitchen costs around $14,000 to $18,000 installed; stock cabinets with laminate counters cost $6,000 to $9,000. The bathroom is similar: a Kohler walk-in shower with porcelain tile runs $7,000 to $12,000 for the bathroom portion of the build; a basic tub-shower combo runs $4,000 to $6,500. These choices compound across a small footprint, so they matter more per square foot than they would in a full house remodel. -
Separate meter vs. shared utilities.
Pompano Beach rental ADUs almost always benefit from a separate electrical meter – it simplifies rent collection, makes the unit more attractive to tenants, and avoids billing disputes. FPL (Florida Power and Light) handles the meter installation, but the electrical scope on our end adds $2,000 to $4,000. If you’re building for a family member rather than a market-rate tenant, shared utilities are a reasonable way to trim the budget.

AfterPompano Beach ADU Permitting: What You Need to Know Before You Build
The City of Pompano Beach Development Services department handles ADU permits, and the process has a few steps that are specific to this municipality – not just generic Florida Building Code requirements. Getting the permitting sequence right upfront saves weeks; getting it wrong can cost months.
Zoning Approval First
Not every residential parcel in Pompano Beach allows a detached ADU by right. Single-family lots in RS-1 through RS-4 zoning districts generally permit ADUs, but setback requirements, lot coverage maximums, and minimum lot size rules vary by district. A survey – typically $800 to $1,500 – is required before permit submittal to confirm the ADU footprint fits within setbacks. In Pompano Beach’s historic districts, there are additional design review requirements that add both time and architectural drawing cost.
Signed-and-Sealed Drawings Are Mandatory
Broward County requires architectural drawings signed and sealed by a Florida-licensed architect or engineer for any new residential structure. Generic stock plans are not accepted. Budget $4,000 to $12,000 for this, depending on the complexity of the unit. We coordinate with licensed design professionals as part of our ADU scopes – this is not a step our clients have to navigate alone.
Permit Fees Scale With Valuation
Pompano Beach calculates building permit fees based on the declared construction valuation of the project. For a $140,000 ADU, permit fees generally land in the $4,000 to $6,500 range. Impact fees – which fund Broward County schools, parks, and transportation infrastructure – add another layer. Impact fees for a new residential unit in Pompano Beach can add $3,000 to $7,000 depending on unit size. These are not optional and are not negotiable; they’re government-set figures. Any contractor who omits them from a written quote is giving you a number that will grow before the permit is issued.
Inspection Schedule
A typical Pompano Beach ADU build requires foundation, framing, rough plumbing, rough electrical, insulation, and final inspections at minimum – and more if there’s a separate electrical service. Each inspection has to be scheduled and passed before the next phase begins. Our written scope includes the full inspection schedule so you know what to expect at each phase, not just at the end.

Detached ADU vs. Garage Conversion vs. Home Addition in Pompano Beach
These three paths to an ADU have very different cost profiles and very different permit timelines. The right choice depends on your lot, your budget, and what you’re building the unit for.
Detached ADU: $90,000 - $220,000
A new detached structure built on the rear portion of the lot. This is the most expensive option but also the most flexible – you’re not constrained by an existing structure’s footprint, ceiling height, or utility routing. In Pompano Beach’s Collier Manor and Cypress Isle neighborhoods, where lots are wide and rear setbacks are workable, detached units are the standard approach. The rental income potential is also highest here because the unit is fully private with no shared walls.
Garage Conversion: $30,000 - $80,000
Converting an attached or detached garage into a livable space. The structure already exists, so you’re not paying for foundation, framing, or roofing. You are paying to bring the space to residential code: insulation, drywall, HVAC, plumbing if a bathroom is included, electrical upgrade, and egress. A single-car garage in Pompano Beach converts to roughly a 250-to-300-square-foot studio; a two-car garage to roughly 400 to 500 square feet. The permit path is similar to a full ADU build – it still requires signed-and-sealed drawings and all the same inspections.
Home Addition (Attached ADU): $45,000 - $130,000
Adding square footage to the existing footprint of the house, with a separate entrance that creates a functionally independent unit. This is common on corner lots in Pompano Beach where a side entry is practical. Cost is lower than a fully detached unit because you’re sharing at least one wall and potentially the main roof. The tradeoff is sound transmission between the units and the structural complexity of tying into an existing foundation and framing system.

How to Save on ADU Construction in Pompano Beach
There are legitimate ways to reduce the cost of an ADU build in Pompano Beach. None of them involve cutting corners on structural or code requirements – those cuts tend to surface at the final inspection or, worse, at the sale of the property.
-
Start with a garage conversion if you have the structure.
A two-car garage gives you 400 to 500 square feet of ADU without the cost of a new foundation, framing, or roof. You’re spending $30,000 to $80,000 instead of $90,000 to $220,000. If the structure is sound and the location on the lot works, this is usually the highest-ROI path. -
Choose a simpler roofline.
A flat or shed-slope roof costs less than a gable or hip roof in materials and framing time. Flat rooflines are also common in Pompano Beach’s coastal architectural style, so they don’t look like a compromise. A GAF or Owens Corning modified bitumen system on a flat ADU roof is a practical, code-compliant choice at a lower cost than tile or metal. -
Use a mini-split HVAC system.
A single-zone mini-split from a reliable brand is almost always the right call for an ADU in Pompano Beach. It’s efficient, it doesn’t require ductwork, and it runs $3,500 to $9,000 installed. A ducted system in a small footprint costs more and doesn’t cool better. -
Budget honestly for permits from day one.
The contractors who quote ADUs in Pompano Beach without permit fees, impact fees, and engineering costs are not saving you money – they’re moving those costs to a future conversation. Get a written scope that itemizes permits, impact fees, and design professional fees before you compare quotes. A lower number that excludes these items is not a lower number. -
Phase finish selections deliberately.
If you’re building for a rental tenant rather than a family member, mid-grade finishes perform as well as high-end ones in the Pompano Beach rental market. KraftMaid cabinets and Cambria countertops are a good mid-grade combination that photographs well for rental listings and holds up to tenant use. Saving $8,000 to $12,000 on kitchen and bath finishes doesn’t reduce the rent you can charge in most Pompano Beach neighborhoods. -

ADU Return on Investment in Pompano Beach
Pompano Beach’s rental market makes ADU math worth running. Single-bedroom rentals in Pompano Beach were averaging $1,700 to $2,400 per month in early 2026, depending on location and finish level. A 600-square-foot one-bedroom ADU that rents for $1,900 per month generates roughly $22,800 in annual gross rent.
On a $145,000 ADU build (a realistic mid-range number for a detached one-bedroom in Pompano Beach), that’s a gross yield of around 15.7% before expenses. Net yield after maintenance, insurance, and vacancy typically runs 10% to 12% in this market. That’s a meaningful return on a construction investment – and it’s why ADU permits in Pompano Beach have increased steadily since Florida’s 2021 ADU preemption law made local zoning restrictions on ADUs much harder to enforce.
The Intracoastal neighborhoods east of Federal Highway – Cypress Isle, Harbor Village, and the blocks around Pompano Beach’s marina district – tend to support the highest rents for well-finished ADUs. Neighborhoods west of I-95, including Collier City and parts of Cresthaven, offer lower land costs and still support rents in the $1,500 to $1,900 range for a finished unit.
If you’re evaluating whether to build, a written quote with a real scope is the only way to run honest numbers. You can find general pricing information here – but a quote specific to your lot, your existing utilities, and your unit design is what actually tells you whether the ROI works. That quote is free, and it comes with a written price before any work starts.

FAQs – ADU Construction Cost in Pompano Beach
How much does it cost to build an ADU in Pompano Beach, FL?
ADU construction in Pompano Beach costs $90,000 to $220,000 for a new detached unit. A 500-to-650-square-foot one-bedroom unit with a small kitchen, full bath, mini-split HVAC, and impact windows typically runs $130,000 to $165,000. Garage conversions cost less – $30,000 to $80,000 – because the existing structure is already in place. Call (754) 714-6540 for a written quote specific to your lot and unit design – estimates are free.
How long does it take to build an ADU in Pompano Beach?
From permit submittal to final inspection, most ADU builds in Pompano Beach take 8 to 14 months. The permit review process at the City of Pompano Beach Development Services office typically takes 6 to 12 weeks for a new residential structure; construction itself runs 4 to 7 months depending on unit size and finish complexity. The variables that extend timelines most are incomplete permit submittals and inspection scheduling delays – both of which are manageable with a complete set of signed-and-sealed drawings submitted correctly the first time.
Do I need a permit to build an ADU in Pompano Beach?
Yes. Every ADU in Pompano Beach requires a full building permit, signed-and-sealed architectural or engineering drawings, and a series of inspections covering foundation, framing, rough plumbing, rough electrical, insulation, and final. Permit fees typically run $3,000 to $8,000, and Broward County impact fees add another $3,000 to $7,000 depending on unit size. Any contractor who tells you they can build an ADU in Pompano Beach without permits is describing unpermitted work – which will create serious problems at sale and potentially result in demolition orders.
Is it cheaper to convert a garage or build a detached ADU in Pompano Beach?
A garage conversion is significantly cheaper – $30,000 to $80,000 versus $90,000 to $220,000 for new detached construction. The savings come from not needing a new foundation, structural framing, or roof. The tradeoff is that you’re limited to the existing footprint and ceiling height of the garage, and you may lose parking that Pompano Beach zoning requires. If your lot and parking situation allow a garage conversion, it’s almost always the lower-cost starting point. Call (754) 714-6540 and we’ll tell you what your specific structure and lot support.
What is the maximum ADU size allowed in Pompano Beach, FL?
Florida state law caps ADU size at 1,200 square feet or 50% of the primary dwelling’s gross floor area, whichever is smaller. For a 1,600-square-foot house, the ADU cap is 800 square feet. The City of Pompano Beach applies its own zoning setbacks and lot coverage limits on top of the state cap, so the effective maximum for your specific parcel may be smaller. A survey and a pre-application meeting with Pompano Beach Development Services is the right first step – both of which we can walk you through as part of the planning process for your project.
