A Canyon home with land needs a budget for the residence and the infrastructure that makes the site usable. Taxes, water arrangements, wastewater, access, vegetation work and insurance require different evidence. Gross acreage alone cannot determine those costs. The Canyon guide introduces the approach and site investigation; this worksheet uses exact local public bills and current government fee inputs while leaving private operating costs open for actual quotes.
The two parcel examples are 13 and 50 Pinehurst Road, identified by current County annual bills checked October 26, 2026. Their acreage, current systems and physical condition were not independently verified. They are public-bill comparison anchors, not a claimed conventional-home-versus-acreage field study. No water tariff, pumping invoice, road agreement, contractor bid or insurance proposal was obtained for either home. Those limits remain visible in the worksheet rather than being replaced with invented local averages.
Build the tax component from the actual parcel
The 13 Pinehurst Road bill, number 2026-270381 for APN 257-160-028-3, shows $12,116.28 in ad valorem taxes and $457.66 in special taxes and assessments. The published annual total is $12,573.94. Its direct-charge section includes a $51 stormwater line and a $73.48 line labeled Moraga fire service district. Those are bill entries, not private road, well or insurance invoices.
The 50 Pinehurst Road bill, number 2026-270220 for APN 257-031-014-0, shows $27,586.20 in ad valorem taxes and $487.50 in direct charges, totaling $28,073.70. It includes a $87.54 Moraga fire service district line and a separate $12 EBRPD CFD No A/C-3 line. Keep the actual labels and amounts; do not assume the same charge list applies to every Canyon parcel.
Both bills identify tax rate area 61000 and a combined ad valorem rate of 1.0606 percent, but their assessed bases differ. Their totals therefore cannot be compared as though one generic tax percentage answers the ownership question. The published values are not market prices or proof of usable land. Their direct charges also do not establish which private infrastructure or maintenance obligations the owner must fund separately.
Keep future assessment and cash timing separate
Dividing the current annual totals by twelve produces $1,047.83 and $2,339.48 for monthly planning. That arithmetic describes the published bills, not the payment schedule or a future buyer’s tax liability. The County explains that supplemental bills can arise in connection with ownership changes or new construction. Obtain appropriate transaction-specific information before using the current owner’s tax figure as a purchase forecast.
Retain a separate first-year cash column. A closing, supplemental bill, immediate repair and annual service may fall at different times. Reconcile taxes and insurance with any lender impound estimate so the same amount is not included twice. One-time agency fees and construction deposits also belong outside recurring-service totals until the worksheet explicitly describes how the owner plans to fund them.

| Published annual total | $12,573.94 | $28,073.70 |
| Annual ÷ 12 | $1,047.83 monthly planning equivalent | $2,339.48 monthly planning equivalent |
| Private water, wastewater, road, grounds and insurance | Unknown for these parcels. Obtain actual rights, records, inspection scope, invoices and dated quotes; do not substitute tax lines for these costs. | |
| Published Land Use fee inputs | Arithmetic if both named items apply | Exclusions |
|---|---|---|
| Conventional OWTS plan review $2,336; construction permit $521 | $2,857 for these two government entries | Actual required scope, design, testing, contractor work and other fees. |
| Alternative OWTS review $3,134; construction permit $7,346 | $10,480 for these two entries | Different system category; not an optional price upgrade or complete replacement estimate. |
| Site evaluation $438; percolation $604; soil profile $514 | $1,556 if all three apply | Not automatically required together or added to every project. |
Source: actual current Land Use fee table. Complete separately for a real property: routine service / immediate repairs / project completion / capital replacement / shared allocation / agency fee / source date / next refresh. No private price, inspection or acreage classification is invented.
Price the actual water arrangement
State records identify Moraga Heights Mutual Water, CA0707585, with a physical-location contact in Canyon. That does not establish a household connection or current tariff for either tax example. Obtain the actual supplier or shared-source documents and current charges. Do not apply another East Bay utility’s retail rate simply because its service territory is familiar.
If the home uses a private well, identify pumping energy, equipment, treatment where actually required, testing and maintenance through the property’s records and appropriate review. If it uses a shared system, identify regular charges and the owner’s separate equipment obligations. Keep replacement funding distinct from routine service. A low recurring invoice does not establish that the owner has no responsibility for future capital work.
The local school system reinforces the need for exact identity. Canyon School has its own State water-system number, CA0707620, at 187 Pinehurst Road. Its institutional source is not a tariff or service entitlement for nearby residences. Use the actual home account or well file to choose the budget inputs, then obtain any needed proposal from a provider familiar with the actual arrangement.
Distinguish wastewater operating costs from project costs
Establish whether the home has sewer service or an onsite system before assigning a cost category. No such private determination was made for the two examples. For an onsite system, request the approved design and service records and obtain an appropriate current inspection. Routine service, corrective repairs and a replacement project are different budget items. The absence of a sewer line on an annual tax bill does not establish the actual system.
Contra Costa Health’s Land Use Program provides the local well and onsite wastewater review route. Its current fee table distinguishes conventional and alternative systems and separate site work. The worksheet shows arithmetic for selected published entries only. A government permit subtotal does not include contractor construction, professional design or every review that an actual project might require.
For a proposed addition, ask how the intended use relates to the existing approved infrastructure before pricing the building alone. The fee table includes a separate review category for additions, remodels and new structures with plumbing fixtures. A scoped project budget should identify the relevant approval assumptions and site work, rather than treating an open area or existing tank as proof that the infrastructure supports the proposal.
Budget the approach and grounds from documented responsibilities
Trace the actual maintenance route and obtain the road agreement where one applies. Identify the covered segment, responsible parties, allocation method and planned work. Do not divide a guessed road cost by the number of nearby homes. Ask the appropriate reviewer to explain the actual obligation, and obtain bids tied to that scope. A public Pinehurst project does not establish what the owner owes on a private approach.
Scheduling can also affect project planning. The County’s October 2026 Pinehurst notice announces a conditional daytime work window and closures on a public segment. Confirm current route conditions with contractors and service providers before relying on a work date. The notice is not evidence of a private road defect or a recurring household charge.
For grounds, identify the area actually maintained and the work needed, rather than multiplying every acre by a generic rate. Trees, access clearances, drainage features and ordinary garden work may require different scopes and approvals. MOFD’s community chipping program invites Canyon residents and describes a free service, but availability and preparation requirements need confirmation. It is not a quotation for complete vegetation removal, tree work or ongoing property care.
Obtain an actual insurance proposal
Give the licensed insurance professional an accurate description of the residence, other structures, infrastructure, access and intended use. Retain the proposal date, covered property, limits, deductibles and important conditions. The California Department of Insurance guide explains why replacement cost differs from purchase or land value. Neither gross acreage nor the tax assessment supplies the needed coverage amount or premium.
Keep insurance questions distinct from fire-agency review and vegetation work. MOFD’s service overview includes Canyon, but that does not guarantee a policy or resolve every private access condition. Likewise, participation in a program is not proof of current compliance or policy eligibility. Use the actual written proposal and appropriate agency information as separate evidence in the ownership file.
Bring a traceable ledger to the financing discussion
Mark each amount as a dated bill, a published government fee, an actual scoped quote or an unresolved input. Separate immediate work from recurring costs and longer-term replacement funding. Do not combine the real tax examples with hypothetical infrastructure prices and label the result a measured household total. The open fields identify the next documents needed to make the budget useful.
The financing guide helps place the completed ledger within the wider purchase payment discussion, and the Contra Costa County guide supplies jurisdiction context. A reliable Canyon budget follows the actual property’s obligations and infrastructure. Its precision comes from verified inputs and clear limits, not from filling every unknown with a convenient average.
