Garage Conversion Cost in Hialeah
Whether you're searching "garage conversion cost," "convert garage to living space," "turn garage into living space," or "garage conversion contractors near me," you're looking for the same thing: a licensed team that gives you a real number, not a range that grows once demo starts. D&Co Homes is a full-service garage conversion contractor — not a referral service — so the price we quote is the price a licensed crew actually charges to do the work.
Here's what garage conversion cost in Hialeah typically looks like, broken out by scope:
If you've been comparing "garage remodel cost" or "garage renovation cost" quotes and getting wildly different numbers, the most common reason is scope hidden in the fine print — one contractor's "conversion" includes a permit and inspection, another's doesn't. We put the exact scope in writing before you sign.
Permits & Regulation in Hialeah
Converting a garage into habitable space is classified as a change of use under the Florida Building Code, which means Miami-Dade requires a full building permit — not a cosmetic-renovation permit. That means signed, sealed plans, an egress window for any room used as a bedroom, minimum 7-foot ceiling height, insulation and HVAC upgrades that meet the same energy code as new construction, and a final inspection before the space counts as legal square footage. Typical residential review runs 10-15 business days.
High-Velocity Hurricane Zone (HVHZ): All of Miami-Dade County sits inside the High-Velocity Hurricane Zone (HVHZ) — the strictest wind and product-approval standard in the country. When a garage door opening is closed in and replaced with a code-compliant exterior wall, any new window or door in that wall needs a Miami-Dade Notice of Acceptance (NOA) confirming it meets 175+ mph wind standards. A standard window or door from outside the zone will fail inspection, no matter how well it's installed.
Many South Florida garages also sit at or below Base Flood Elevation (BFE). If yours does, the conversion can trigger FEMA flood-venting or elevation requirements — a step that's easy to miss and expensive to fix after the fact. We check flood zone status before writing your quote, not after.

Know Who's Working In Your Home
Miami-Dade has seen a steady stream of unlicensed-contractor cases move through local courts in 2025 and 2026 — homeowners paying tens of thousands of dollars for renovation work that was never finished, or never started at all. Local news outlets have reported several such cases this year alone, including one where a homeowner paid over $39,000 for a kitchen renovation and was left with a non-functioning space, and another where a contractor took a $9,000 deposit and never began the job.
Unpermitted garage conversions carry a specific financial risk beyond fines: most homeowner's insurance policies exclude unpermitted work entirely. If your converted garage suffers hurricane or water damage and an adjuster discovers there was never a permit on file, that portion of the claim can be denied outright — and some carriers have canceled policies after finding an unpermitted conversion during an inspection. Before hiring anyone for a garage conversion in Hialeah, verify their license number directly at myfloridalicense.com, and confirm they intend to pull a permit, not skip it.

Common Questions
A garage conversion in Hialeah typically runs $18,000–$65,000, depending on garage size and scope. A single-car garage converted to a basic bonus room runs $18,000–$28,000; a single-car garage converted to a studio ADU with kitchenette and bathroom runs $32,000–$48,000. A double garage converted to bonus/flex space runs $28,000–$40,000, and a double garage converted into a full accessory dwelling unit runs $40,000–$65,000. We give a written, fixed-price quote after seeing the space, not a phone estimate.
Yes. Converting a garage into habitable space is a change of use under the Florida Building Code, which means a full building permit is required in Hialeah — not a simple cosmetic-renovation permit. Skipping this step means the added square footage never counts toward your home's legal, appraised value.
Not automatically. A garage conversion turns your existing garage into additional habitable space — a bedroom, office, or family room — that's still part of your primary home. It only becomes a legal Accessory Dwelling Unit (ADU) if it includes its own kitchen, bathroom, and separate entrance, and meets your city's ADU zoning and parking rules. We can scope either version depending on what you actually need.
Many South Florida garages sit below Base Flood Elevation (BFE). If yours does, converting it to habitable space can trigger elevation or flood-venting requirements under FEMA and local floodplain rules, and skipping that step can jeopardize your flood insurance eligibility later. We check this before writing your quote.

It depends on scope: a basic conversion (insulation, drywall, flooring, closing in the garage door opening) runs lowest; adding a bedroom with an egress window and closet is the most common project we quote; and a conversion with a bathroom or kitchenette added runs highest.
