The city requires any building or general contractor working in Lubbock to register, and that takes proof of at least $100,000 in general liability insurance or a $20,000 compliance bond, so it's fair to ask anyone bidding your job about it. The city and the state each list an energy code for commercial buildings, and they aren't the same edition, so before we start I check with the city which one your project falls under.
If the insulation is part of a bigger project, a new build, addition or alteration permit valued at $50,000 or more means the city requires the project to meet the Texas accessibility standards and register for state review and inspections, which is worth knowing when you plan the schedule. We're based in Lubbock and work in the cities around it too, including Wolfforth, Slaton, Levelland, Plainview, Littlefield and Brownfield, where we see the same mix of metal shops, offices and older storefronts.
