Building In San Antonio, Regulations & Guidelines

The International Residential Code (IRC) is a comprehensive code that establishes a minimum standard for many of the components involved in the construction or repair of a one-or two family-residence, one-to-three stories high. Covered elements include building materials, plumbing, electrical systems and energy efficiency. Most cities with residential building codes adopt the IRC as their basic standard. San Antonio, like many other cities, amend the IRC to better suit local requirements. Rest assured that when you choose us to build on your lot San Antonio codes are strictly enforced. We also go one step further for our clients by providing third-party inspections following the completion of each one of the ten critical construction phases.
