A Corte Madera ownership budget needs to distinguish ordinary bills, property maintenance and larger site or adaptation work. Those categories have different evidence and payment timing. A shoreline planning initiative is not a funded private repair, and an annual sewer assessment should not be added twice because it appears within the tax bill and in a separate budget line.
This guide builds a local evidence framework and documents a real discrepancy between published sewer-charge sources. It does not invent two private home budgets or contractor and insurance quotes. The Corte Madera overview supplies broader context; the purpose here is a cost model whose inputs can be checked before a purchase decision.
Begin with the actual payer and collection method
Identify each service, who bills it and where the charge appears. Water, sewer, refuse, property taxes and association payments should have separate evidence even if some are collected together. Confirm parcel jurisdiction with the County lookup, then establish the actual provider rather than assigning all charges from the mailing address.
Sanitary District No. 2 describes a collection area including the Town and limited neighboring areas, with treatment provided through Central Marin Sanitation Agency. That service arrangement does not define municipal zoning. For budgeting, obtain the actual account or parcel assessment and distinguish collection, treatment and private-lateral work.
Use a common period for both candidate homes. Identify which amounts are annual, monthly or billed every other month. A current quote, a historical bill and a tariff calculation should carry different labels. The comparison becomes misleading if one candidate includes a replacement allowance and the other simply omits the same responsibility.
Audit official sewer figures before using a total
The District’s linked connection-charge packet is internally headed for fiscal2026–2027, despite an older filename. Its service-charge paragraph prints $906.10 per user unit plus a $2 collection charge. The same packet contains differing treatment-connection figures between its main schedule and examples, so it should not be used uncritically as a universal current quote.
Separately, Resolution 01/2026 contains a multiyear annual wastewater schedule showing $1,087.32 for the July 1, 2026 step. These printed amounts require reconciliation with the actual current parcel assessment and District response. This article does not select the lower figure as an affordability assumption or assert a final bill for a buyer.
The difference is practical: two official-looking documents can refer to different periods, contain retained text or require an underlying resolution check. Keep the document date, internal heading and applicable year with every rate. Ask the District to confirm the amount, user-unit assignment and any collection component in writing before completing the ownership total.
Keep connection and development charges separate from regular service. A new dwelling, added fixtures or changed use may need a different analysis from continuing existing service. Obtain the project-specific requirements rather than treating an example connection charge as a recurring annual cost or assuming an existing bill approves all future demand.
Original asset: source audit and two-candidate budget register
The first table compares printed source figures; it is not a current quote. The second is an original annual comparison structure awaiting actual property inputs.
| Source | Printed annual service figure | Treatment in this budget |
|---|---|---|
| Packet internally headed FY 2026–2027 | $906.10 per user unit; separate $2 collection text | Flag period/source consistency; not accepted as a final bill |
| Resolution 01/2026 schedule, July 2026 step | $1,087.32 per equivalent unit | Reconcile with current assessment and District response |
| Arithmetic difference before collection components | $181.22 | Demonstrates why source reconciliation matters; no property savings claimed |
| Component | Candidate A | Candidate B | Evidence and double-count check |
|---|---|---|---|
| Taxes including collected assessments | Buyer-specific estimate | Buyer-specific estimate | Actual bill and tax review; mark included sewer amounts |
| Utilities outside tax/dues | Confirmed annual total | Confirmed annual total | Accounts, current tariffs and usage assumptions |
| Insurance | Actual terms/premium | Actual terms/premium | Coverage, deductibles, occupancy and binding conditions |
| Regular maintenance | Defined annual service scopes | Defined annual service scopes | Private drainage, site structures and building responsibilities |
| Immediate/capital work | Separate cash and replacement plan | Separate cash and replacement plan | Condition findings, scope, timing and rights |
Method: original reconciliation and cost framework. Sources: District packet and resolution schedule. No hypothetical full total masks missing financing, tax, insurance or repair inputs.
Separate public adaptation from private work
The Town’s January 2026 flooding archive points to recovery and preparedness work. Its May 19, 2026 staff report distinguishes public shoreline/infrastructure protection from private property adaptation. Those are related efforts with different decision makers, funding and responsibilities.
For a candidate home, obtain the actual property history and any proposed adaptation or repair scope. A public grant application or survey initiative should not be entered as a completed private improvement or guaranteed payment to the owner. Ask which work is funded, authorized, proposed or still under study, keeping the dates with the response.
Separate routine preparedness and maintenance from damage repair and long-term changes. They may involve different inspections, permissions and costs. No local home-elevation price, expected flood loss or insurance claim amount can be inferred from this article or from a community-wide planning discussion.
Build the drainage and retaining-structure cost file
Identify the features that support the home’s usable spaces and access. Obtain qualified condition findings and available plans for important retaining or drainage work. Establish ownership and maintenance responsibility through the appropriate records. A structure’s proximity to the property does not determine who must fund every repair.
The Town’s Public Works resources identify separate routes for grading, drainage, erosion control and watercourse work. Ask the project team which reviews and investigations affect an actual proposed repair. The contractor’s construction scope and the agency’s permit process need to be budgeted with their dependencies visible.
Put recurring service in one column, immediate work in another and later replacements in a third. State which amounts are actual scoped quotes and which remain allowances. An attractive private outdoor area may require supporting work, but no blanket percentage or hillside premium can replace the property’s own evidence.
Compare insurance terms and buyer taxes on a consistent basis
Obtain written insurance terms for the address and intended occupancy. Compare coverage, deductibles, exclusions and outstanding conditions, as well as premium. Ask whether coverage can be bound for the required date. A seller’s historical policy or an area map cannot substitute for the buyer’s actual insurance inquiry.
The Department of Insurance distinguishes official wildfire maps from insurer models. Flood-related coverage and lender requirements also need their own responses. Avoid combining all water or hazard questions into a single assumed homeowners premium.
Use Marin County’s tax-bill guide to identify assessed values and charges on the actual parcel bill. Have the buyer’s situation reviewed by the appropriate advisers. Mark assessments already included in the tax total so they are not duplicated as independent service expenses.
Test cash needs, not just annual averages
The sewer-source discrepancy is an input-control issue rather than a reason to assume the entire budget is unknowable. The next useful evidence is a current parcel assessment and an agency explanation of the applicable period and units. Once obtained, replace the provisional source note with that supported figure and record why it changed. Apply the same discipline to insurance renewals, service classifications and revised repair scopes.
For a two-candidate comparison, identify differences in responsibility before comparing totals. One home may have an expense included in an association payment while another requires a direct contract. A missing direct bill does not prove that the service is free, and a larger combined payment may include work absent from the other model. The worksheet should make those differences visible without forcing unrelated costs into identical lines.
Do not use a public capital plan as a private replacement reserve. A Town project can affect the surroundings while the owner still maintains private drains, structures or equipment. Determine what the public work actually includes and what remains excluded. The same caution applies to a proposed grant: eligibility, award and payment are separate stages, and no household benefit is assumed until its evidence exists.
An annual average can hide a difficult first-year payment sequence. Taxes, annual insurance and identified work may arrive before monthly allowances accumulate. Prepare a cash calendar showing due dates, expected funding and items outside lender escrow. Keep a seller credit or existing reserve distinct from the recurring cost of maintaining the property.
For each decision-sensitive unknown, identify the next evidence needed and who can provide it. Do not complete a total by inserting a convenient official number whose period is unresolved. A clearly incomplete input is more useful than a precise figure that cannot be supported.
Use the financing guide for the lender discussion and the Marin County overview for regional orientation. The final Corte Madera budget should show verified recurring obligations, condition-based work and the unresolved inputs that still affect affordability.
