Building a custom home in Oro Valley
Oro Valley lots sit under Pusch Ridge and the Santa Catalinas, often with slope, washes and big views. Most are in planned communities with an HOA, and the town has its own permit office and zoning code. Getting a custom home built here is as much about sequencing approvals as it is about construction, and that is where we start.
What the town asks for on a new home
The town's residential construction handbook sets out what goes in with a new home permit. The items that shape the design and schedule are:
- A site plan with property lines, easements, setbacks, utilities and the square footage of every roofed area.
- A grading permit where needed. On lots that weren't mass graded, plans show existing and proposed topography from a certified source.
- A lot-specific soils report with slope and foundation recommendations for lots that weren't mass graded. Where the average cross slope is over 6%, natural grade must be shown on the elevations.
- A check with the Planning Division, since some new homes need extra review.
- Proof of the Pima County sewer or septic fee before the permit is issued.
- Energy, structural, electrical and mechanical documents, including load and cooling calculations. Fire sprinklers may be required, so we confirm that early.
Mass-graded lot or custom lot?
The town's handbook draws a line between lots that were mass graded when the subdivision was built and lots that weren't. A mass-graded lot in a newer subdivision usually has a ready pad, and fewer site documents are needed. A custom lot on a slope, or an older parcel that was never graded, needs topography, a soils report, grading plans and often more foundation work. If you are still choosing a lot, that difference can move the budget a long way, so it is worth a site walk before you buy. Our guide to hiring a licensed Arizona contractor covers what to ask any builder at that stage.
Sensitive lands, slopes and views
Oro Valley's Environmentally Sensitive Lands rules cover hillside areas, riparian washes, distinctive native plants and the scenic corridors along Oracle and Tangerine Roads. Under the hillside standards, slopes under 15% aren't restricted, slopes of 15% to 25% can be developed in a limited way, and steeper areas are mostly conserved. Many of these rules were written for rezonings, so which ones touch your lot depends on its zoning and history. We read your lot's conditions before design, because they decide where the house can sit and how tall it can be.
HOAs and planned communities
Much of Oro Valley was built as planned area developments. Rancho Vistoso, for example, has its own PAD document, design guidelines and an architectural review committee. Expect your HOA to review elevations, colors, roof materials and landscaping before construction. We prepare the package and build that review into the schedule ahead of the town permit. More on that community is on our Rancho Vistoso page.
Adding a casita to the plan
Planning a guest casita alongside the house? The town allows one ADU on a single-family lot, but it won't issue the ADU permit until the main house has a permit and has passed intermediate inspections. We plan the two together so the casita follows without delays. See our Oro Valley casita page.
How we build your Oro Valley home
- Consultation and site walk. Your lot or the one you're considering: slope, washes, access, utilities and HOA.
- Plans review. If you have an architect's drawings, we review and price them. If not, we talk through next steps for design.
- Written estimate. A clear scope of what's included and excluded.
- Approvals. HOA review, grading and the town building permit.
- Build. Our own crew does the framing, structural work, stucco and roofing, with one licensed contractor (AZ ROC #344537) responsible throughout.
- Inspections and handover. We schedule town inspections and walk the finished home with you.
