Home Addition Miami

Room additions, second story additions, garage conversions, in-law suites, and covered extensions built to Miami-Dade code by OD Construction Group Corp. Expand your home without leaving the neighborhood you chose.

Types of Additions We Build in Miami

Every home addition project in Miami-Dade starts with a feasibility review of your lot size, setback requirements, zoning classification, and existing foundation. We tell you what is buildable before you spend a dollar on plans.

Room Additions

Single-story lateral additions for new bedrooms, expanded living rooms, family rooms, home offices, or sunrooms. We tie the new structure into your existing foundation, roof line, and exterior finishes so the addition reads as original construction, not an afterthought.

Second Story Additions

Full second story additions or partial pop-up additions that double your living space without consuming additional lot coverage. Includes structural engineering for the existing foundation, load-bearing wall reinforcement, stair design, and complete MEP rough-in for the new floor.

Garage Conversions

Convert an attached or detached garage into conditioned living space. Structural framing for insulated walls and ceilings, HVAC extension, electrical panel assessment, and finish work to match the main house. A garage conversion is often the most cost-effective way to add a bedroom or home office in Miami.

In-Law Suites

Detached or attached accessory dwelling units and in-law suites with private entry, bedroom, bathroom, and kitchenette. We navigate Miami-Dade ADU ordinance requirements, coordinate utility connections, and build to the same finish standard as the main residence.

Covered Patios + Extensions

Engineered aluminum or CBS covered patio structures, screen enclosures, and pool deck extensions. Wind-rated to Miami-Dade NOA standards. We design outdoor living extensions that connect seamlessly to the home interior through new sliding glass or folding glass door openings.

Home Additions Under Way in Miami-Dade

From the framing stage through final inspection, every OD Construction Group Corp home addition is built with the same structural standards and attention to detail we apply to new custom homes.

Miami Licensed Home Addition Contractor

A home addition that is not permitted, engineered, and tied properly into the existing structure creates insurance risk, resale issues, and potential safety problems. We do it by the book, every time.

Home Addition Miami FAQ

Questions we answer every week from Miami homeowners considering an addition.

Yes, always. Any home addition in Miami-Dade County that adds conditioned square footage, modifies load-bearing walls, extends plumbing or electrical service, or changes the roofline requires a building permit. There are no exceptions. An unpermitted addition will surface during any title search when you sell, can trigger a code enforcement order requiring demolition, and is not covered by your homeowner insurance. OD Construction Group Corp pulls all required permits as a standard part of every home addition project.
A standard room addition in Miami typically takes 4 to 6 months from permit submission to final inspection, including 8 to 12 weeks for permit review. A second story addition, which requires more structural engineering and a longer plan review cycle, generally runs 8 to 12 months. Garage conversions and covered patio enclosures with simpler structural requirements can be permitted and completed in 3 to 5 months. We provide a complete project schedule at contract signing so you have accurate expectations from day one.
Home addition costs in Miami depend on type, size, and scope. A single-story room addition typically runs 250 to 400 dollars per square foot in Miami-Dade. A second story addition, which requires structural reinforcement of the existing home, runs 300 to 500 dollars per square foot. Garage conversions range from 80 to 150 dollars per square foot depending on finish level. In-law suite additions with a full kitchen and bathroom range from 180 to 350 dollars per square foot. We provide detailed itemized proposals after a site visit and feasibility review so your number is accurate for your specific home and lot.
In most cases, yes. Adding a second story to a single-story Miami home is a project we handle regularly. The first step is a structural assessment of your existing foundation and first-floor framing to determine load capacity. Miami-Dade building code requires that the entire structure, including existing walls, headers, and connections, meet current wind load and lateral force requirements when a second story is added. We engage a licensed structural engineer to evaluate your home and design the reinforcement required before any permit application is filed. If your home and lot support it, a second story addition is one of the best investments in Miami current market.
