Are ADUs allowed in Henderson?

Yes — the City of Henderson permits accessory dwelling units on most single-family lots subject to zoning rules covering setbacks, lot coverage, parking and utility separation. We run a zoning check on your specific parcel up front.

What does a casita cost in Henderson?

Most detached casitas in Henderson run $200,000–$450,000 depending on size, kitchen scope, separate utilities and finish level. Tier-by-tier breakdown in our casita & ADU cost guide.

How long does the build take?

Roughly 5–7 months total — 8–12 weeks of design and Henderson plan check, then 12–18 weeks on-site from foundation to certificate of occupancy.

Will the casita match my main house?
