Lafayette ownership costs should be built around the particular property, including the grounds and improvements that make it usable. A mortgage estimate does not explain parcel levies, utility billing, private drainage duties or the cost of a defined retaining project. Start with actual documents and separate recurring payments from inspection-driven work. A household can then see what is established, what depends on its usage and which private amounts still need a current quote.
This worksheet is checked October 26, 2026. It uses two actual current-year County tax statements and separate hypothetical EBMUD water profiles. No actual household service accounts, insurance quotes, contractor estimates or private inspection findings were supplied. The utility examples are not assigned to the named tax properties. No combined annual household total is presented, because doing so would conceal the unresolved address and private-cost inputs.
Trace two actual annual tax statements
The County statement for 1280 Panorama Drive, parcel 246-070-012-9, bill 2026-266015, shows $26,519.18 in ad valorem taxes and $2,476.68 in special taxes and assessments, totaling $28,995.86. The 3484 South Silver Springs Road statement, parcel 240-131-006-1, bill 2026-264009, shows $37,756.68 plus $2,476.68, totaling $40,233.36. These are public document examples, not new-owner tax forecasts or properties represented as currently for sale.
Both show a combined ad valorem rate of 1.0833% and the same special-charge total, while the taxable assessments differ. Their annual total difference is $11,237.50. That comparison does not establish the properties’ present market values or private maintenance demands. It shows why the current owner’s assessment cannot be treated as a universal Lafayette tax allowance. Obtain a transaction-specific prospective estimate before using a bill as part of a purchase affordability decision.
The special-charge rows already contain the listed levies. Each example includes $784 for CCCSD sewer and $59.50 for the displayed stormwater line. If the full tax-statement total is entered in the annual budget, those amounts belong inside that total rather than as additional separate expenses. Preserve the statement’s collection method for school and other parcel levies as well, so a lender’s impound schedule and the underlying bill are not counted as two different costs.
Separate public sanitary service from private site drainage
Central San’s current financial information identifies fiscal-year 2026–27 annual service charges, including $784 for a single-family residence. That published category agrees with the sewer line in the two actual tax examples. It does not authorize applying the same category to every property or proposed additional unit. Use the actual bill and provider classification, especially where a property includes another dwelling or a different service arrangement.
Private drainage is a different funding question. The City’s Public Works page says many drains and ditches on private land remain the owner’s responsibility unless a public drainage easement was formally accepted. Identify the actual route, accepted scope and recorded rights where relevant. A sanitary service charge or tax-billed stormwater levy is not evidence that a private yard drain, retaining-wall system or crossing will be replaced by a public agency.
Use the applicable water account, not a general bill label
The July 2026 EBMUD water schedule separates the meter-based service fee, usage tiers and elevation surcharge. For an illustration, assume a small standard meter, single-family classification, six identical bimonthly cycles and 14 CCF per cycle. The selected Band 1 water components are $57.20 plus 14 times $8.40, or $174.80 per cycle. Six cycles produce $1,048.80. This is a labeled usage model, not a measured bill for either tax address.
A second profile uses 20 CCF per cycle under the same assumptions. Its first 14 CCF use the first tier and the next six use $9.74, producing $233.24 per cycle and $1,399.44 annually. The difference reflects usage crossing a tier boundary; it is not an observed cost difference between Panorama Drive and Silver Springs Road. Replace the assumptions with the actual account’s consumption and billing period before applying the model to a purchase.
Elevation creates a separate sensitivity. Under Band 2’s $1.33-per-CCF surcharge, the selected annual water profiles become $1,160.52 and $1,559.04. Do not assign a band from the word hillside or a visible view. Obtain the actual account designator and meter information, and recalculate other fees or adjustments only where they apply. This article does not add an assumed EBMUD wastewater-treatment charge to the Lafayette examples; the sanitary evidence used here is the identified Central San tax-billed service.

| Already included in each special-charge total | Central San sewer $784.00 and displayed stormwater line $59.50. Do not add twice. | ||
| Profile | Band 1 per cycle | Band 1 annual | Band 2 annual |
|---|---|---|---|
| 14 CCF/cycle | $57.20 + 14 × $8.40 = $174.80 | $1,048.80 | ($174.80 + 14 × $1.33) × 6 = $1,160.52 |
| 20 CCF/cycle | $57.20 + 14 × $8.40 + 6 × $9.74 = $233.24 | $1,399.44 | ($233.24 + 20 × $1.33) × 6 = $1,559.04 |
| Input | Scope to establish | Funding treatment |
|---|---|---|
| Drainage/retaining | Actual responsible party, qualified findings, design, access, approvals and restoration. | Separate routine care, investigation and capital work. |
| Insurance | Current address-specific quote and relevant terms. | Annual premium separate from deductible cash exposure and optional coverage. |
| Energy/refuse/shared costs | Actual account and governing documents where relevant. | Reconcile included charges before annualizing. |
| Prospective taxes | Transaction-specific current estimate and assessment information. | Separate recurring estimate from transaction-period or supplemental amounts. |

Annualization here holds the checked water schedule constant to make the two profiles comparable. It is not a guarantee that every charge will remain unchanged for a future twelve-month ownership period. Preserve the tariff date and refresh the account inputs before the purchase. If a billing period crosses a later rate change, apply the actual effective dates instead of treating this snapshot as a forecast.
Give site work a defined scope before comparing costs
Make a component register for the actual grounds. Identify relevant retaining features, accessible drains, roof-water arrangements, driveway surfaces and any shared facilities. Record the responsible party from the appropriate documents. A feature can require care without needing replacement, and a visible symptom does not determine the cause. Obtain the qualified investigation needed for the actual concern before requesting a repair price based on a presumed solution.
Separate maintenance, study and construction. Routine clearing of an accessible component, a technical investigation and replacement of a substantial supporting feature are different purchases. Ask whether a quote includes necessary design, access, approvals, site protection and restoration. On a constrained lot, those details can affect the scope substantially, but no universal Lafayette hillside multiplier is assumed here. The estimate should explain the actual work and the conditions under which its price applies.
Lafayette’s building-process page identifies City fees and separate agency schedules, including the County’s building role. Do not assume that one quoted permit or design allowance covers every reviewing body. Ask for current project-specific inputs, keeping an optional expansion separate from work necessary to maintain the present residence. A public application valuation is not a private construction quote or an approved household budget.
Complete the insurance and household rows from current evidence
Obtain a dated quote for the actual residence and relevant coverage. The Department of Insurance guide provides background for those questions, not a premium for a Lafayette home. Record the annual premium separately from deductibles, exclusions and optional coverage choices. Neither a local fire-service description nor another owner’s older policy establishes present insurability on the desired terms.
Use actual energy and refuse account information, together with current association or shared-maintenance documents if they apply. Identify what a regular payment includes before adding separate allowances. If a service is already paid through a collective arrangement or the tax roll, explain where it appears. Keep household consumption choices separate from the obligations conveyed with the property so that two candidates can be compared without disguising differing assumptions.
Build a payment calendar alongside the annual worksheet
Show recurring annual obligations, transaction-period amounts and separately scheduled work in distinct rows. An impound transfer is a funding method for an underlying bill, not another expense. A capital project needs its actual payment schedule rather than an arbitrary monthly average that hides when cash is needed. If a quote or responsibility remains unresolved, leave the line open and identify the evidence required before calculating the complete household total.
Use the worksheet with the financing guide, the Lafayette hub and Contra Costa County guide. A useful budget explains the source, collection route, period and scope of each amount. It gives the household a practical way to fund the specific residence while leaving unsupported tax forecasts, private repair prices and coverage conclusions out of the arithmetic.
