One metro, several permitting authorities
A “Houston” mailing address does not always mean a property sits inside Houston city limits. Katy, Sugar Land and Missouri City each have their own municipal processes, while unincorporated Harris and Fort Bend county locations follow different requirements. The scope matters too: paint and cabinet replacement are not treated the same way as moving plumbing, electrical systems or structural walls.
We confirm the project address and requested changes before answering permit questions. That short check is more useful than a generic promise that every remodel needs a permit or none do.
