Structural Engineering Services for Home Additions & Remodels Across Florida

Home additions and remodels in Florida must tie safely into your existing structure while meeting the Florida Building Code for hurricane wind loads and flood zone requirements. ProStruct Engineering provides licensed structural engineering services statewide, delivering permit-ready plans for additions, second stories, and structural remodels that integrate seamlessly with your home.

Why Choose Our Home Addition & Remodel Services?

Jurisdiction-Specific Structural Expertise

We know the permit requirements of Florida's city and county building departments, including the flood zone substantial improvement (50%) rule, which can trigger elevation or upgrade requirements for additions and remodels.

Seamless Tie-In to Your Existing Home

We evaluate your existing framing, CMU walls, and foundations, then design new beams, connections, and a continuous wind load path so your addition or load-bearing wall removal performs as one structure.

Fast 2–3 Week Turnaround

Permit-ready structural calculations and drawings delivered quickly, without compromising safety or compliance with Florida building standards.

Types of Home Additions & Remodels in Florida

Every home addition and remodel comes with unique structural considerations. Our engineers design home additions in Florida that tie safely into your existing structure and meet the Florida Building Code for wind loads and flood zone requirements, from interior remodels to second-story additions.

Home Remodel

Kitchen, bathroom, or whole-house remodels that open up floor plans often involve load-bearing wall removal. We design the beams, posts, and connections needed to keep your home's load path and hurricane resistance intact.

Room Addition & Home Extension

Extending your home to the rear, front, or side adds living space at ground level. We design the new foundation, walls, and roof framing, and the tie-in to your existing structure, so the addition performs as one building in high winds.

Second-Story Addition

Adding a second story increases living space without expanding your home's footprint. We evaluate whether your existing CMU walls and foundation can carry the new loads, then design the framing, reinforcement, and wind uplift connections needed.

ADU Addition

An attached or detached Accessory Dwelling Unit adds rental income or space for family. We engineer ADUs to local ADU rules and Florida wind and flood requirements, including garage-to-ADU conversions.

Sunroom & Florida Room Addition

Sunrooms and Florida rooms bring the outdoors in year-round. Their large glass openings and lightweight roofs need careful engineering for hurricane wind pressure and secure attachment to the main house.

Lanai & Outdoor Living Space

Covered lanais, patios, porches, pool decks, and outdoor kitchens extend your living space. We design roof covers, beams, and footings, and the connections to your home, to resist Florida's wind uplift.

Structural Site Inspections

Our engineers visit your site to assess conditions that affect the structural design of your home, addition, ADU, deck, or retaining wall, including soil, drainage, existing framing, and flood zone exposure.

Structural Calculations

We perform load calculations to determine how your structure will resist hurricane-force winds, wind uplift, and gravity loads under the Florida Building Code. These calculations set the size and connections of beams, columns, load-bearing walls, and foundations, including projects in the High-Velocity Hurricane Zone (HVHZ) in Miami-Dade and Broward.

Structural Plans

Based on the calculation results, our engineers prepare structural plans for your framing, foundation, and roof systems, with the tie-down and connection details Florida building officials expect.

Structural Permit Sets

Each permit-ready package includes detailed drawings, specifications, calculations, and supporting documentation, signed and sealed, and formatted for submission to your city or county building department to obtain a building permit.

Construction Administration

We provide construction administration support throughout your build by responding to Requests for Information (RFIs), performing submittal reviews, addressing substitution requests, and conducting structural observations. This keeps construction aligned with the approved plans and the Florida Building Code, and helps resolve unforeseen structural issues quickly.
