Local Intelligence
What Miami Homeowners Need to Know Before Submitting
Size & Zoning Rules
0Miami does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
A fully permitted, code-compliant garage conversion in Miami can command approximately $2,550/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
City of Miami Building Department permit fees for this project type typically range from $2,500 to $10,000 depending on project valuation and scope. Plan check runs approximately 7 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Garage conversion drawings submitted to City of Miami Building Department must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus stamped structural plans are typically required for converted garages that are detached or require seismic upgrades.
Visit City of Miami Building Department ↗Construction Cost Context
Miami's garage conversion construction costs run $200–$320 per square foot — a wide range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.
⚠ Common Pitfall in Miami
Because most Miami lots sit inside the state-mandated Coastal Construction Control Line, your ADU plans need a separate Coastal Development Permit on top of the standard building permit — this pulls in Miami-Dade's environmental review and typically tacks on 4-8 extra weeks before you even get to plan review. On top of that, the City of Miami requires proof your electrical panel and water lateral can handle a second unit, which often means an engineer's letter confirming the existing service size, since older Miami homes (built pre-1990s) rarely have capacity documented anywhere the reviewer can just look it up. And since short-term rentals aren't allowed for ADUs here, your certificate of occupancy will explicitly restrict the unit to long-term tenancy, which some homeowners don't discover until final inspection sign-off.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 7-week timeline and $250/sqft figure are Miami state-level estimates, not gospel — I'd call the City of Miami Building Department directly and get a couple of local contractor quotes before you budget or schedule around them. What the data doesn't show is that your coastal overlay likely triggers a CDP review, which in my 11 years has added anywhere from 4 to 12 extra weeks depending on the reviewer's queue and how clean your drawing set is the first time through."

Miami has a median home value of $503,000. Comparable renovation projects in this market typically add 25.0% to resale value.
Neighborhoods in Miami with the strongest garage conversion and rental-unit potential include Pinecrest, Coral Gables, Coconut Grove, Miami Shores, Little Havana. Very large single-family lots and estate zoning make detached ADUs feasible.

Design review: Other - administrative site-plan review required; additional reviews (historic preservation review or coastal overlay reviews) may apply depending on location.

Common Questions
Miami Garage Conversion FAQs
Is a garage conversion allowed in Miami? +
Yes — garage conversions are permitted in Miami. Florida state law allows homeowners to convert an attached or detached garage into habitable living space or an ADU. A building permit and permit-ready drawings are required before work begins.
How much does a garage conversion cost in Miami? +
Garage conversions in Miami typically range from $100,000 to $220,000 depending on the existing structure, finish level, and scope of work. This is significantly less than building a new detached ADU. Our drawing package starts at $997 — a fraction of what a local architect would charge for the same permit-ready set.
What drawings are required to permit a garage conversion in Miami? +
Miami's building department requires: a site plan showing the converted garage's location on the lot, floor plans with dimensions and room labels, all four exterior elevations, an electrical plan, and energy compliance documentation (Title 24 in California). Our Starter package covers all of these. If the garage is detached or the structure requires seismic upgrades, stamped structural drawings are also required — included in our Premium package.
How long does the permit process take for a garage conversion in Miami? +
Plan check in Miami typically takes approximately 7 weeks. Having complete, code-compliant drawings dramatically reduces correction cycles — which each add 3–6 weeks. Our drawings are designed to pass on the first submittal.
Can I convert my garage into a rental unit in Miami? +
Yes — a permitted garage conversion can function as a standalone rental unit (ADU or JADU depending on size). In California, converted garages under 500 sq ft qualify as Junior ADUs (JADUs), while larger conversions qualify as full ADUs. Both can be rented long-term. Short-term rental rules vary by city — confirm with Miami's planning department.
Do I need to replace the garage door opening when converting? +
Yes. The garage door must be replaced with an insulated wall with a standard entry door and at least one egress window (minimum 5.7 sq ft clear opening). This is captured in our elevation drawings and flagged in the electrical plan. The new wall must also meet FL energy code requirements, which we handle in the Title 24 compliance documentation.
How much does it cost to get garage conversion drawings in Miami? +
Our permit-ready garage conversion drawing packages for Miami start at $997. Local architects typically charge $2,500–$6,000 for the same set. Every package is engineered for FL code compliance and formatted for Miami's building department. Turnaround is 10 business days with a 14-day money-back guarantee.
Will converting my garage increase my home's value in Miami? +
A permitted garage conversion in Miami adds rentable square footage to a home currently valued around $503,000. Converted spaces typically appraise as habitable square footage, increasing the home's value. As an ADU or JADU, the rental income stream is also capitalized into the appraised value — typically at a 5–6% cap rate.
