PERMITS & LICENSING
Permits and licenses in Deerfield.
Permits and who issues them
Deerfield takes building permit applications online through its Permitting and Licensing portal. There's no application just for water heaters. An 'Uncategorized Project (Permit Required)' type is used only when the Building Division says so. Ask the Building Division whether your replacement needs a permit.
Yes. Plumbing, electrical, general, roofing, irrigation, excavation, concrete and sewer contractors must register, and so must homeowners doing their own work. General, excavation and concrete contractors post a $20,000 surety bond.
