Hempstead Building Permits Start at the Town Portal
For a Town of Hempstead project, use the Building Department and online permit center before assuming a county office handles it.

A Hempstead home project should start with the town, not with a vague Nassau County search.
The Town of Hempstead Building Department uses the Online Permit Center. It has building permits, forms, and related details. The department handles rules for building, plumbing, wiring, housing, unsafe buildings, public spaces, use, and occupancy. The portal accepts permit filings. It also shows status, takes inspection requests, displays old permits, connects users with staff, and prints permits.
Before a fence, addition, basement change, or rental setup, check the address and village status. Gather the work details, contractor information, old permit question, and inspection need. Then open the Online Permit Center.
