City of Houston Development Services — What You Need to Know

Submissions to Houston Permitting Center (iPermits) / Harris County ePermits are reviewed against Texas building code as adopted locally, plus Harris County’s own zoning and site rules. We prepare each plan to the applicable local naming and submission requirements.

Local note: Houston is one of the only major U.S. cities with no formal zoning code u2014 development is instead governed by Chapter 42 building line and subdivision rules, plus any private deed restrictions on your lot. We check both before drafting your plan.

Pool, fence, ADU and home-addition permits are common across Houston. Site plans typically need lot coverage, setback lines, and equipment or structure placement clearly shown.

Setback and lot-coverage rules in Houston vary by zoning district and, in some cases, by subdivision deed restrictions. Rather than publish generic numbers that may not apply to your property, we look up your parcel’s actual zoning designation and confirm exact setbacks before we draft your plan.
