Building Code
Locally adopted International Building Code (editions vary; many major cities on 2021 IBC, others on 2018 or 2015)
Texas · Licensed Professional Engineering
Site engineering that clears local review — grading, drainage, and utilities designed to each jurisdiction's published standards from day one.
Permit stuck waiting on a seal? Apex Grid's licensed engineers provide fast Civil review-and-seal for drawings in Texas and across the state — reviewed under responsible charge and sealed for submittal to the applicable Texas permitting authority. Typical turnaround is 3–5 business days once we have a complete package.
Civil and site engineering in Texas is a drainage discipline. Houston's flat topography and repeated flood events (Harvey chief among them) mean Harris County and the City enforce demanding detention, fill-mitigation, and finished-floor elevation rules that can reshape a site plan entirely. Elsewhere, expansive clays complicate pavement and utility design, and each major city publishes its own drainage criteria manual — we design to the specific manual rather than a generic standard. Stormwater quality, TCEQ construction general permit coverage, and SWPPP documentation apply to sites over an acre statewide. Our grading, detention, and utility layouts are built around each jurisdiction's published criteria and the reality that in much of Texas, moving water off-site responsibly is the hardest part of the entitlement.
Code adoptions change on multi-year cycles and many states allow local amendments. The researched source verification date is 2026-07-28; we verify the governing edition with your permitting jurisdiction at project kickoff.
Permitting varies dramatically by jurisdiction: Houston famously has no zoning but enforces strict floodplain and drainage criteria, while Dallas and Austin run structured plan-review with published amendment packages. Coastal counties add windstorm (TDI/TWIA) inspection and certification requirements that must be planned into the schedule.
Texas offers licensure by reciprocity for qualified out-of-state PEs and requires firms to hold a Certificate of Registration. Digital/electronic seals are accepted on submittals per board rules.
Texas leads the nation in construction volume, driven by relentless population growth, corporate relocations to DFW and Austin, Gulf Coast petrochemical and LNG expansion, and a booming data-center and semiconductor pipeline. Warehouse/industrial and multifamily starts remain strong across the major metros.
