MAV Design & Build builds second-story additions throughout League City TX and Galveston County, transforming single-story homes into spacious two-story residences. Adding a second story is the most efficient way to expand your living space without reducing your yard or lot coverage — particularly valuable in League City’s waterfront and master-planned communities where horizontal expansion is limited. We handle structural engineering, HOA approvals, City of League City permitting, and all construction under a single fixed-price contract.
Full vs. Partial Second-Story Additions in League City TX
MAV builds both full second-story additions that expand over the entire footprint of the existing home and partial additions that target a specific wing or zone. A full second story typically adds a master suite, secondary bedrooms, bathrooms, and a hallway above the main living level. A partial addition is often used to add a master suite above the garage or bedrooms above an existing family room while leaving a cathedral ceiling in the main living area.
Second Story Addition Costs in League City TX
Second-story additions in League City TX range from $142,000 for a partial expansion to $295,000 or more for a full second-floor addition with multiple bedrooms, two bathrooms, and premium finishes. League City’s proximity to the Bay Area Houston employment corridor and NASA makes second-story additions a strong equity investment. MAV provides fixed-price estimates after a structural assessment of the existing foundation.
How Long Does a Second Story Addition Take in League City TX?

HOA design review in South Shore Harbour, Tuscan Lakes, and other master-planned communities and City of League City permit processing add 5 to 7 weeks before construction begins.

The PE assesses the existing slab or foundation to confirm it can support the additional vertical load. HOA design review is required in most League City planned communities before permits are submitted. MAV manages engineering, HOA submittals, permit applications, and all city inspections.
