Common mistakes that delay your Construction Permit in Katy

These are the issues that send applications back for correction in Katy most often. Avoid them up front and you'll typically clear the queue in the 1-6 weeks window.

Submitting an incomplete application. Roughly half of Katy Construction Permit delays trace back to missing signatures, the wrong form revision, or fees paid to the wrong department. Run through the Katy clerk's checklist twice before you submit.
Filing without confirming zoning first. Even in mid-sized cities like Katy, applications get rejected because the proposed location isn't zoned for the use described in the application. Pull a zoning confirmation letter from Katy's planning desk before the licensing application goes in.
Missing a required inspection or certification. Health-and-safety licenses in Katy are usually contingent on a third-party inspection (fire marshal, environmental health, or building). Coordinate those inspections in parallel — sequencing them adds weeks.
Not budgeting for renewal. The first Building Permit fee is only part of the cost — renewals (one-time per project) cost roughly 60–70% of the initial fee, and missing the renewal window in Katy typically means re-applying from scratch.
