When moving up means agent commissions, closing costs, and a bigger mortgage, adding on is often the smarter play — especially in established Tampa Bay neighborhoods where the right addition returns more than a relocation. The key is an addition that looks like it was always there, not bolted on.
LRG Contractors Group designs and builds room additions, primary-suite additions, second stories, and bump-outs that match the home's architecture, roofline, and proportions. We handle the structural and wind-load engineering Florida requires, foundation work, and the plan review the county or city demands.
Whether you're adding bedrooms for a growing family in Brandon, a primary suite in Wesley Chapel, or a second story in St. Petersburg, we confirm what your zoning and Florida Building Code wind requirements allow before drawing a line.

Our process
- 1
Feasibility & zoning check
We confirm what your lot's zoning, setbacks, and flood zone allow before design — so the plan is buildable.
- 2
Design & engineering
We design the addition to match the home, engineer the structure, foundation, and wind loads, and deliver a fixed proposal.
- 3
Permits & plan review
We pull permits and represent the project through the jurisdiction's plan-review process under the Florida Building Code.
- 4
Build
Foundation, framing, weatherproofing, and finish — tied cleanly into the existing structure and built to code wind ratings.
- 5
Walkthrough & inspection
We pass inspection, blend the new and old seamlessly, and finish the punch list.

Typical Tampa Bay ranges, not a quote. Additions price by square footage, structural complexity, wind-load requirements, and foundation work. Second stories cost more because the floor below must be reinforced. You get a fixed proposal after design.

Room additions typically run 3–5 months; second stories 5–9 months, including design, engineering, and permitting.
Permits & code
Additions require structural permits and engineering, including Florida Building Code wind-load and wind-borne-debris compliance, and jurisdictions apply setback and lot-coverage standards. We handle zoning analysis, permits, and plan review.
Key things to consider
- Confirm zoning, setbacks, and flood zone first — they shape what's buildable.
- Florida wind-load and wind-borne-debris requirements affect framing, windows, and cost.
- Matching the roofline and exterior is what makes an addition look original.
- Second stories cost more because the lower floor needs reinforcement.
