Comparing a Sausalito house with a condominium requires an annual ledger that follows the money through several payment routes. A house owner may pay a contractor directly for work that a condominium association funds through dues. Sewer service can appear on the secured property tax bill. Water may be billed to an individual meter or paid through an association. Adding every document total together can therefore overstate costs, while comparing only mortgage payments can leave substantial obligations out.
Use the Sausalito guide to establish the housing context, then compare actual candidates using the same categories. This article concerns land-based houses and condominiums. Floating homes need a separate account of berth and ownership arrangements, explained in the floating homes and houseboats guide. The illustration below uses a published water tariff and hypothetical consumption. It is a partial cost model, not a quotation or a complete budget for any property.
Separate the amount owed from the way it is collected
Begin with the candidate’s actual secured tax bill, utility accounts, insurance quotation and association documents, where applicable. Record the billing period and named account holder for each. The County’s October 2026 tax-bill guide identifies direct charges and assessments separately from assessed value and basic tax. An owner’s existing assessed value is not a promise of the buyer’s future tax result. Have the appropriate adviser establish the buyer-specific projection.
The collection route determines how to avoid duplication. If the annual budget starts with the full secured bill, a sewer charge already included there should be tagged for analysis without being added again. If the ledger starts with tax alone, separately entered service charges must reconcile to the bill. Similarly, an impound payment moves money toward an obligation; it is not a second property expense to add on top of the obligation already recorded. Use the financing guide for broader loan planning, then ask the lender to reconcile the actual payment presentation.
Refresh the sewer file after the collection-system transfer
The Sausalito-Marin City Sanitary District assumed the City collection system in August 2025. An old worksheet showing a continuing City collection charge and a separate District charge needs reconciliation with current billing. The District’s documents index now includes Ordinance No. 104 concerning City collection rates. Ask the District to confirm the actual parcel classification, annual components and collection route before adopting a total.
This is a practical source check, not a reason to guess a replacement amount. The index itself displays differing effective-date labels for the ordinance, and an older rates explanation retains pre-transfer City responsibilities. Neither label should substitute for the governing instrument and actual account confirmation. Record the unresolved item explicitly, with the bill and fiscal year needed to close it. A blank pending verified evidence is more useful than a precise number assembled from incompatible periods.
For a condominium, identify whether sewer costs are charged to the unit, paid by the association or allocated through another documented arrangement. Confirm how a shared lateral is maintained and funded. A current recurring service charge does not include every possible private repair. The budget should distinguish utility service from the association’s or owner’s future construction obligations rather than treating the sewer line as a single all-inclusive expense.
Use water as a controlled comparison
The Marin Water table effective July 1, 2026 supplies the inputs for the original illustration below. For the assumed single-family account and three-quarter-inch meter, the two-month service and capital charges total $122.83. Within the first consumption tier, water and watershed charges total $11.52 per unit. Both hypothetical consumption levels stay within that tier. Confirm meter size, account class and all applicable charges before adapting the model.
The important comparison is billing responsibility, not an assumption that condominium residents use the single-family tariff. If an association pays a master-meter bill, obtain its actual account information and allocation method. Do not divide this illustration by the number of units or apply it to an unidentified master meter. In the household ledger, a water cost funded through dues belongs in an explanatory breakdown of dues; it is not another direct bill unless the documents show a separate payment.
Original annual cost comparison and inclusion check
| Calculation | 9 units each period | 14 units each period |
|---|---|---|
| Fixed service plus capital | $71.76 + $51.07 = $122.83 | $122.83 |
| Water plus watershed charge | 9 × ($10.86 + $0.66) = $103.68 | 14 × $11.52 = $161.28 |
| Two-month subtotal | $226.51 | $284.11 |
| Annualized water subtotal | $1,359.06 | $1,704.66 |
| Annual difference | $345.60; not a house-versus-condominium cost estimate | |

Put dues beside the duties they fund
Annualize the actual regular dues and separately list adopted special assessments and their payment dates. Then describe the included services and reserve contribution without adding those components again to total dues. The Department of Real Estate’s August 2026 guidance provides a useful disclosure framework. Request the current documents and relevant updates rather than relying on a listing’s rounded dues figure.
A house owner’s equivalent planning column should be based on its own components and condition. If the house has private retaining structures, exterior stairs or difficult repair access, obtain appropriate investigation and scoped cost information. A percentage of purchase price can obscure those differences. For the condominium, check whether comparable structures belong to the association, whether reserve planning includes them and whether additional owner responsibilities remain. Sharing a project changes its funding and decision process; it does not make the underlying work disappear.
Keep cash due in the coming year separate from longer-term saving. An adopted assessment payable this year is a cash obligation. An owner’s planned contribution to a personal repair fund is a saving decision. A reserve contribution already included in regular dues is part of those dues. Present all three clearly so the household can compare liquidity demands without adding the same reserve funding twice.
Carry uncertain projects outside the recurring total
Use a separate project register for work that has been discussed but not priced or adopted. For each item, show the affected component, responsible party, evidence date and present stage. An association minute requesting bids does not establish the owner’s final assessment. A house inspection recommending further evaluation does not establish the repair scope. Keeping these items visible outside the recurring total lets the reader see what remains uncertain without converting a tentative concern into a fictitious annual expense.
When reliable scope and price information arrives, move it into the appropriate time period. Explain whether the amount is a one-time payment, recurring maintenance or a proposed saving contribution. If a project also changes ongoing costs, document that change separately; a new roof contract does not itself prove a particular insurance saving. Compare alternatives at the same evidence stage. A fully priced condominium assessment and an uninvestigated house repair should not be presented as equally certain figures merely because both appear in adjacent columns.
The water illustration shows why separating assumptions matters. Its annual difference comes entirely from consumption while fixed charges remain the same. It does not measure gardening behavior, occupancy or the effect of a particular fixture. Replace the hypothetical periods with actual account history when available, identify unusual readings or vacant periods, and ask the provider to explain the applicable account setup. A buyer’s intended use may differ from the seller’s, so retain the usage assumption beside the number rather than burying it in a footnote.
Price the coverage and timing gaps
Compare actual insurance terms with the property’s repair responsibilities. For a condominium, ask the insurance adviser to explain the owner/master boundary, relevant deductibles and loss-assessment conditions. The Department of Insurance guide supplies context, while the policies determine the actual coverage. A budget should identify uninsured or uncertain exposures instead of treating the premium as proof that every major expense is covered.
Finally, plot payment timing. Two properties with similar annual estimates may demand different cash reserves if one has a near-term assessment or contractor deposit. Keep a separate list of unresolved amounts and the evidence required to resolve them. Compare other Marin County homes through the same ledger. The result should explain both the expected annual spending and the decisions that could change it, without presenting a hypothetical subtotal as the cost of owning a particular Sausalito home.
