Summary

Henderson charges a residential construction tax, capped at $1,000 per unit, on new dwelling units under HMC Section 19.17, and an accessory dwelling unit counts as a unit before you get a building permit.

There is hereby imposed and shall accrue and be collected a residential construction tax, as provided in this Section, upon the privilege of constructing residential dwelling units, including, without limitation, conventionally constructed houses, apartments, mobile homes, nonresidential structures remodeled for use as dwelling space, room additions, mobile home parks, and mobile home estates within the City. The residential construction tax shall be calculated at the current legal rate for each residential dwelling unit, per NRS. The residential construction tax shall not exceed $1000 per unit or as otherwise as provided in NRS.

Full Breakdown

Henderson's Development Code doesn't carve out a separate ADU impact fee: it applies its citywide residential construction tax instead. HMC Section 19.17.1 imposes the tax 'upon the privilege of constructing residential dwelling units,' a category broad enough to cover an accessory dwelling unit added to a lot, and caps it at $1,000 per unit or the rate Nevada Revised Statutes otherwise sets. Section 19.17.2 requires payment before the city issues the building permit. Money collected funds park-district improvements under Section 19.17.3, not ADU-specific infrastructure.

Violations & Fines

Henderson won't issue the building permit until the residential construction tax is paid; there's no separate penalty schedule, but skipping payment blocks the ADU from ever being permitted.

Frequently Asked Questions

Does Henderson have a special impact fee just for ADUs?
No. Henderson's code has no ADU-specific fee: it applies the citywide residential construction tax under HMC Section 19.17.1, capped at $1,000 per unit, to any new dwelling unit including an ADU.
When is Henderson's residential construction tax due?
Before the city issues the building permit. HMC Section 19.17.2 requires payment at that point, unless the tax is waived under a negotiated development or park agreement.
