The short answer: the number a builder gives you for a Scottsdale custom home may not represent the entire amount required to create the finished property. Depending on how the project is structured, land, architecture, engineering, interior design, surveys, soils work, HOA review, permit fees, utility work, landscape, pool, furnishings, financing costs, and certain owner-direct purchases may sit outside the construction contract.
That does not mean those costs are being hidden. It means every custom home budget needs a clear definition of what the number includes and what it does not.
Two builders can present numbers that appear hundreds of thousands of dollars apart while ultimately describing almost the same project. One may include site work, pool allowances, appliances, permit fees, and landscape. Another may place some or all of those outside the contract. The lower number is not necessarily the lower-cost project.
At Bella Legacy, we believe the useful comparison is not the headline construction number. It is the expected total project investment for the home and property you actually intend to complete.
Start by Separating the Construction Contract From the Total Project
A custom home project usually contains several financial layers. The builder’s construction contract is one of them, but not always all of them.
- Land acquisition – the homesite itself and any acquisition-related costs.
- Soft costs – architecture, engineering, surveying, soils work, consultants, interior design, and similar professional services.
- Hard construction costs – labor, materials, subcontractors, supervision, site construction, and the physical building work.
- Exterior property improvements – pool, spa, landscape, irrigation, hardscape, walls, gates, outdoor kitchens, lighting, and related work.
- Owner-direct costs – furnishings, art, certain appliances or specialty systems if purchased directly by the owner.
- Financing and carrying costs – construction-loan fees, interest, appraisal costs, and other lender-related expenses where applicable.
The categories can overlap. Some builders include many of them. Others intentionally exclude them. Neither structure is automatically wrong. The problem begins when the owner assumes the scope is included because the budget does not make the distinction clear.
1. The Homesite Is Usually Separate
When someone says a custom home costs a certain amount per square foot, that figure almost never includes the land. In Scottsdale, the homesite can represent a significant portion of the total investment, particularly in Silverleaf, Desert Mountain, Estancia, Mirabel, Troon, and other premium locations.
The purchase price is only the beginning. A difficult lot may also create additional construction costs for grading, rock excavation, retaining, drainage, access, utility extensions, or environmentally sensitive land requirements.
This is why we prefer to evaluate a homesite before an owner treats the house budget as though every construction dollar will go into finished square footage.
2. Architecture and Engineering May Sit Outside the Builder Contract
Architecture is typically a separate professional agreement. Structural engineering, civil engineering, surveying, geotechnical work, energy calculations, landscape architecture, specialty consultants, and other design services may also be contracted separately.
Those costs matter because the complexity of the site and architecture affects not only the construction price but also the amount of professional work required before construction starts.
A straightforward flat-lot residence and a highly engineered hillside home are different projects long before the first concrete truck arrives.
3. Interior Design and Selections Need Their Own Budget Conversation
Some custom-home projects include interior design services within a broader design-build structure. Others have a separate interior designer working directly for the owner.
It is also important to distinguish the design fee from the materials being selected. Cabinetry, stone, plumbing, lighting, flooring, appliances, hardware, wall finishes, and millwork may be part of the builder’s construction budget even when the designer’s professional fee is not.
The budget should make both relationships obvious.
4. Permits, Plan Review, and Municipal Fees May Be Separate
Scottsdale charges plan-review and permit fees based on the type and scope of residential work. The City also offers a process to request a project-specific permit fee estimate.
Whether those fees are included in the builder’s price depends on the contract. The Arizona Registrar of Contractors specifically recommends that construction agreements make responsibility for building permits and related terms clear in writing.
That is a useful principle far beyond permits: if a meaningful project cost exists, the budget should identify who owns it.
5. HOA and Community Design Review Costs Can Be Easy to Miss
Many Scottsdale luxury communities have their own architectural review process in addition to municipal review. Depending on the community, owners may encounter design-review fees, deposits, construction deposits, consultant fees, or requirements tied to landscape, site walls, mockups, or construction access.
The amounts and procedures vary substantially by community. They should be researched before finalizing a project budget, particularly when the property is subject to detailed design guidelines.
6. Utility and Infrastructure Work May Not Be Obvious in an Early House Budget
A lot can appear ready to build and still require meaningful utility work. Electrical service, water, sewer or septic, gas, communications, meter work, trenching, transformer coordination, and utility extensions can affect the project before the finished home is visible.
These costs are especially important on larger, older, hillside, or more remote Scottsdale homesites. They should be investigated during site due diligence rather than treated as a late construction surprise.
7. Pool, Landscape, and Outdoor Living Can Become a Second Construction Project
In Scottsdale, the backyard is often part of the architecture. Pools, spas, ramadas, patios, outdoor kitchens, fire features, landscape, irrigation, lighting, walls, gates, and hardscape can represent a significant investment.
Some builder budgets include this work. Some include portions of it. Some treat it as owner-direct scope.
When comparing builder proposals, ask whether the exterior environment shown on the architectural or landscape plans is actually represented in the number you are reviewing.
8. Furnishings, Window Treatments, Art, and Decor Are Usually Separate
The construction contract generally creates the house, not everything required to furnish it. Furniture, rugs, art, decorative accessories, bedding, and certain window-treatment packages may sit entirely outside the builder’s budget.
For a large luxury residence, that can become a meaningful part of the total investment. It deserves its own budget rather than being treated as an afterthought at move-in.
9. Financing and Carrying Costs Are Not Construction Costs
If the project uses a construction loan, lender fees, interest, inspections, appraisals, draw administration, and other financing costs can sit outside the building contract. Owners carrying an existing residence or temporary housing during construction may also have costs that are real to the project but unrelated to the builder’s construction price.
Those numbers do not need to be mixed into the construction estimate, but they should be understood when the owner is establishing an overall project investment.
10. Contingency Is Different From Missing Scope
A contingency is a reserve for uncertainty. It should not be used to disguise work that everyone already knows the project will require.
If the pool is shown on the plans, calling it a contingency item does not make the budget more accurate. If the cabinetry has not been fully selected, a realistic allowance may be appropriate. If a hidden subsurface condition cannot reasonably be known yet, a contingency may be appropriate.
Those distinctions matter because a transparent budget separates known scope, allowances, and true unknowns.
How to Compare Custom Home Budgets More Accurately
Before comparing two builder numbers, put them into the same scope framework.
- What is included in site development?
- Are permits and review fees included?
- Are appliances included, and at what allowance?
- Are cabinetry, stone, lighting, and plumbing allowances realistic for the design?
- Is pool and landscape included?
- Are builder fee, supervision, insurance, and general conditions clearly shown?
- Which professional fees are owner-direct?
- Which utility or infrastructure costs remain unresolved?
- What is specifically excluded?
- What contingency is being carried, and what is it intended to cover?
The Arizona Registrar of Contractors advises homeowners to make sure the project description, price, permit responsibility, payment schedule, and change-order process are clearly addressed in the written agreement. You can review the ROC’s consumer guidance before hiring a contractor and its contract requirements.
Frequently Asked Questions
Does a Scottsdale custom home price usually include the land?
No. Land is generally separate from the construction price unless a specific builder-developer arrangement states otherwise.
Are architect fees included in the builder’s cost per square foot?
Not automatically. Architecture and engineering are often separate owner agreements. Ask whether any quoted cost-per-square-foot figure is construction-only or intended to represent a broader project total.
Are pool and landscape included in a custom home budget?
Sometimes. There is no universal practice. The proposal should state clearly whether pool, hardscape, landscape, exterior lighting, walls, and related improvements are included, allowed for, or excluded.
What is the best number to compare between builders?
Compare the expected total cost for an equivalent scope. A smaller headline contract number is not meaningful if substantial required work is sitting outside it.
The Goal Is a Complete Budget, Not the Smallest Number
A credible custom home budget should make the project easier to understand, not more impressive on the first page. The earlier the owner knows what is included, what remains outside the contract, and what is still uncertain, the easier it becomes to make good design decisions.
At Bella Legacy, we would rather have that conversation before the architecture becomes difficult to change. A realistic total-project view gives the owner more control over where the investment goes – and fewer surprises later.
