A useful Daly City ownership budget begins with the actual account and property documents, then uses current public rates to explain the parts that can be calculated. The City’s water schedule provides a concrete example. It cannot supply the buyer’s tax assessment, insurance offer or repair needs. Keep those inputs separate rather than producing an apparently precise annual total from unrelated assumptions about a house that has not been documented.
This guide uses rates checked October 26, 2026 and develops the ownership questions introduced in the Daly City overview. The numerical comparison below represents two assumed water-use levels on the same ordinary meter size. It is not a pair of inspected or billed properties. All other ownership categories remain tied to the records, quotes and service arrangements of the actual address.
Identify the water provider before choosing the rate
Do not choose a water tariff from the postal city alone. Daly City publishes its own approved water schedule, while California Water Service’s Bayshore/Bay Area Region tariff page also identifies Daly City among its service localities. Use the account, service-area information and provider confirmation for the property under review. An adjacent property or a familiar community name is insufficient evidence that the same tariff and meter configuration apply.
For a City water account with a five-eighths-inch or three-quarter-inch meter, the approved schedule effective July 1, 2026 lists a $63.65 base charge every two months. Its first 13 hundred cubic feet of usage are priced at $7.99 per HCF, followed by $10.58 per HCF through the next tier. The calculation here stays below the third tier. Meter size, billing period and tier boundaries must remain attached to the numbers when copied into a worksheet.
Assume first that consumption is 12 HCF in a two-month period. The selected water components are $63.65 plus 12 multiplied by $7.99, or $159.53. At 24 HCF, the first 13 units still use the first-tier rate; only the remaining 11 use the second-tier rate. That gives $283.90. Charging all 24 units at the higher rate would overstate this example, while dividing the base charge as though it were annual would understate it.
Six identical periods at the same rate produce $957.18 and $1,703.40 respectively, a difference of $746.22. These are constant-rate planning scenarios, not actual calendar-2026 expenses: rates earlier in the year differ, and real consumption changes. The annualization also excludes any other applicable bill items. Its purpose is to show how meter charges and tiered consumption interact, so a buyer can substitute actual readings and the correct effective dates.
Original dated water model and ownership-cost ledger
Checked October 26, 2026. Model assumes City water, a 5/8- or 3/4-inch meter, six identical two-month periods and the approved July 1, 2026 rates. These are selected water charges only.
| Selected water component | 12 HCF per two months | 24 HCF per two months |
|---|---|---|
| Two-month meter base | $63.65 | $63.65 |
| Tier 1 at $7.99/HCF | 12 × $7.99 = $95.88 | 13 × $7.99 = $103.87 |
| Tier 2 at $10.58/HCF | $0.00 | 11 × $10.58 = $116.38 |
| Selected total per two months | $159.53 | $283.90 |
| Six identical periods, unchanged rate | $957.18 | $1,703.40 |
| Annual scenario difference | $746.22; not a forecast or a complete utility bill | |
| Additional budget line | Source to obtain for actual property | Double-counting or timing check |
|---|---|---|
| Property tax and direct levies | Current APN tax bill, charge details and buyer assessment estimate | Separate seller basis, recurring levies and supplemental adjustment |
| Wastewater | Actual district, winter-use basis and tax-roll levy | NSMCSD published FY26–27 90-CCF example is $1,050.30; do not add it again if included in tax total |
| Garbage and other utilities | Current account, carts/service level and actual bills | City water/garbage bill and association-paid services may overlap the worksheet |
| Insurance | Address-specific current offer and coverage terms | Separate annual premium, deductible exposure and any association policy |
| Maintenance and capital work | Actual inspection, component history and dated contractor scope/quote | Recurring service, replacement reserve and immediate project belong in different timing columns |
Primary inputs: approved City water schedule, adopted sewer table and County Tax Collector. Blank property-specific lines are unresolved, not zero.
Keep wastewater separate from the water-use example
Wastewater requires another calculation and collection check. The adopted North San Mateo County Sanitation District table lists a FY2026–27 rate of $11.67 per CCF and shows a 90-CCF example of $1,050.30. That published example is not the charge for every home. The table also lists a minimum; it should not automatically be added on top of a volume charge as though it were a separate meter base.
The district’s billing explanation uses winter two-month water consumption, annualized across six periods, to estimate wastewater flow. Its published example starts with 15 CCF for the winter period, producing 90 CCF annually. This explains why simply applying the water model’s annual consumption to sewer can be wrong: the actual winter basis is a separate input. Confirm that basis and the current levy for the address rather than assuming the example matches the seller’s household.
The same source explains collection through the property-tax roll. If the budget starts with the total tax bill including direct charges, adding the sewer levy a second time overstates ownership cost. Create either a tax-total line that already includes the levy or a clean split between value-based taxes and separately itemized charges. The worksheet must use one method consistently. Keep the supporting bill visible so a later reviewer can trace where each charge went.
Village Serramonte has a separately identified sewer schedule, reflecting a different service arrangement. Do not substitute the general district example automatically. Its published rounded inputs and example also should not be forced into a corrected number without agency clarification. For a specific property, the actual account and levy resolve which schedule and amount apply. This is a reason to verify the service identity, not a basis for declaring that one area has a particular overall ownership cost.
Rebuild the tax line for the buyer’s situation
Obtain the current San Mateo County bill by parcel identifier and preserve the separate charge details. The seller’s total is evidence of the present bill, not a promise of the buyer’s future assessment. County guidance describes reassessment following qualifying ownership changes and new construction. Ask the appropriate assessment and tax professionals to identify the value-based estimate, actual direct levies and any applicable circumstances before inserting an annual buyer amount.
Supplemental taxes belong in a separate transition calculation. The County explains that they address the difference between prior and new assessed values and can produce more than one bill depending on timing. Do not treat that temporary adjustment as a second permanent annual property tax, and do not assume a mortgage payment estimate has resolved it. Retain the relevant assessment notice, actual bill and closing information so the timing can be reconciled with available cash.
Add utilities and insurance without hiding their assumptions
The City’s utility guidance says most residential water and garbage charges arrive every other month, with garbage service affected by the cart arrangement. Use actual service details before estimating that line. In a condominium, ask which utilities are paid through assessments and which remain on the owner’s account. A lower separately billed amount can reflect shared payment. It should not be interpreted automatically as a more efficient building or a service that costs the owner nothing.
Insurance requires a current address-specific offer describing the proposed coverage. Record the premium period, effective date, limits and deductibles, and distinguish the owner’s coverage from any association policy. Public consumer guidance from the California Department of Insurance can help frame questions, but it cannot supply a premium or establish availability for this home. Keep an unresolved quote visibly unresolved rather than entering an unsupported local average that makes the completed budget look more certain.
Separate maintenance cash flow from immediate projects
Build the maintenance section around the actual building. A permit record for an old equipment replacement is useful history but does not establish remaining service life. Use current inspections and defined contractor scopes to distinguish ordinary servicing, near-term corrective work and longer-term replacement planning. For shared ownership, reconcile those components with association responsibilities. An owner should not budget the entire common roof replacement privately if the actual documents allocate it differently, or ignore an interior obligation because assessments are paid.
Keep administrative and transaction expenses in their proper period. The City’s approved FY2026–27 schedule lists the residential resale report at $127. That is a dated report fee, not a yearly tax or a construction-cost estimate. Inspection fees, moving expenses and a proposed renovation likewise need separate timing. The first year may require cash that does not recur, while a replacement reserve represents future work rather than an invoice already due.
Use the financing guide to connect these costs to the proposed loan and the San Mateo County guide for context. Before deciding, replace every material assumption with a current bill, written quote or clearly labeled scenario. The result should explain both expected recurring expenses and the additional cash the household may need at specific times, with no charge counted twice.
