Looking for in-law suites & adus in St. Petersburg? LRG Contractors Group is a licensed Florida general contractor serving St. Petersburg and the surrounding Pinellas County — from Historic Old Northeast, Kenwood, Downtown / Central Avenue and beyond. In-law suites, garage apartments, and accessory units — family space and flexibility, where local zoning allows.
An in-law suite or accessory dwelling can add real value, multigenerational space, or flexibility to a Tampa Bay property — but in Florida the rules are local, not statewide. What's buildable depends entirely on your city or county zoning, your lot, and your setbacks, so the honest first step is a feasibility check, not a sales pitch.
For St. Petersburg specifically, it comes down to local realities: St. Pete's split between protected 1920s historic bungalows and low-lying waterfront blocks means the right remodel in Old Northeast is the wrong one in Shore Acres — we scope to the home's era and its flood exposure, not a template. St. Petersburg runs its own building department under the Florida Building Code; bungalow districts add historic-character considerations, and waterfront blocks like Shore Acres sit in FEMA flood zones where substantial-improvement and elevation rules can apply. We design to those rules from day one. We design and permit your in-law suites & adus around exactly those conditions.

In-Law Suites & ADUs cost
Typical Tampa Bay ranges, not a quote. Cost is driven most by type (conversion vs. attached vs. detached), size, site access, and utility connections — and by whether your zoning allows the unit at all. We give you a fixed proposal after a feasibility visit.
