Working in Henderson
Henderson zoning allows accessory dwelling units on most single-family parcels subject to lot coverage, setback and utility-separation rules. We run a zoning check on your parcel first so you know exactly what's allowed — square footage, height, separate address — before any design work begins.
City of Henderson Building & Safety permitting handled in-house, including structural, mechanical, electrical and plumbing. HOA architectural review for detached casitas coordinated with Anthem CC, Seven Hills, MacDonald Highlands and Lake Las Vegas.

Process
How a Henderson casita & adu construction runs, week by week

Local detail
What's different about building a casita in Henderson
City of Henderson accessory-dwelling rules govern maximum size, height, setbacks and lot coverage, and they're parcel-specific. Before any design work, we pull your parcel data and confirm exactly how much casita your lot legally supports — that number, not your wish list, sets the floor plan.
Henderson HOA review is the real gate on a detached casita. Anthem CC, Seven Hills, MacDonald Highlands and Lake Las Vegas all review accessory structures for height, roof pitch, stucco color, window placement and sightlines from neighboring lots. Expect 3–6 weeks, and expect at least one round of comments; we handle both.
Hillside and terraced Henderson lots often need retaining or grading work before a casita foundation can go in. That's a real line item — sometimes $15,000–$40,000 — and we survey for it during feasibility rather than letting it appear as a change order after demo.
Utility distance drives cost. Trenching water, sewer, gas and electrical across a finished Henderson yard with mature landscape, pool decking or terraced hardscape adds up quickly. We route the shortest viable path in design and price the trenching as its own visible line.
Casita permits are submitted to the City of Henderson Building & Safety Division as a new accessory structure — site plan, floor plan, elevations, structural calculations and energy compliance. Plan review typically runs 6–12 weeks, the longest of any scope we handle. HOA architectural review runs in parallel. Build4U prepares and submits both packages and answers every reviewer comment directly.
