Napa Condos and Townhomes: HOAs, Rentals, Flood Zones and Taxes

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

Napa’s condos and townhomes are a small part of a city built mostly of single-family homes, and the attached homes that do come up range from units near downtown and the Napa River to townhome-style planned developments in residential neighborhoods, plus resort-area condos at Silverado outside the city limit. What separates one from another is less the floor plan than the rules around it: the homeowners association’s budget and insurance, whether lenders will finance the project, how close it sits to the river, and the city’s tight cap on vacation rentals.

Inside the City of Napa, city zoning and vacation-rental rules apply, sewer service comes from Napa Sanitation District, and the county’s documentary transfer tax is shared with the city. Silverado is unincorporated Napa County, with county rules instead. This page covers what to check on any Napa condo or townhome.

Where Napa’s attached homes are, and who governs them

The city’s policy documents give a sense of scale. Its housing chapter, adopted in March 2015 using 2013 figures, put single-family homes, detached and attached together, at about 62% of the city’s housing and duplexes and apartments at about 27%. It doesn’t count condominiums separately, and those figures are now dated, so treat them as context.

Downtown and the river. Attached homes near downtown and the Oxbow trade on walking distance to restaurants and the riverfront. They’re also the homes where the flood check below matters most.
Residential neighborhoods. Townhome and condo complexes sit among single-family streets across the city, including in west Napa and on the east side; our guides to Browns Valley and Alta Heights cover two of those neighborhoods.
Silverado. Condos and cottages around the Silverado resort are outside the city limit, so Napa County, not the city, sets the rules. See our Silverado guide.

The city also regulates conversions of rental developments to condominium ownership, a policy its housing chapter says is meant to conserve rental housing. If a building was converted from apartments, ask for the conversion approval and the public report, and read how repairs were handled at conversion.

Confirm the jurisdiction for every address before you rely on any rule on this page. For the city as a whole, see our Napa homes and neighborhoods guide, and for the wider county, Napa County real estate.

The HOA documents a seller must provide

Under Civil Code section 4525, the seller of a unit in a California common interest development must give the buyer, as soon as practicable before transfer of title or signing the sales contract:

the governing documents (CC&Rs, bylaws and rules), and a statement if the association isn’t incorporated;
the most recent annual budget report and related documents;
a statement of current regular and special assessments and fees, and any unpaid assessments, fines or penalties that are or may become liens;
any approved change in assessments or fees not yet due;
any unresolved violation notice, and any construction defect notices the association has sent members;
a statement describing any rental or leasing prohibition;
on request, the board minutes from the past 12 months; and
the most recent balcony, deck and stairway inspection report under section 5551.

What to read first

The annual budget report under Civil Code section 5300 is the best single document. It must include the reserve summary and funding plan, a statement of whether the board has deferred repairs to major components, any special assessments the board expects with their amount and timing, outstanding association loans, and a summary of the association’s property, liability, earthquake, flood and fidelity insurance with limits and deductibles. For a condominium project, it must also say, on separate pages, whether the project is FHA-approved and VA-approved.

In a river-adjacent complex, read the flood line of that insurance summary closely. Then price your own unit policy and any flood coverage before you remove contingencies; our guide to homeowners insurance during escrow covers the timing, and our overview of how HOAs work covers the basics.

Financing: FHA, VA and conventional approval

A condo loan depends on the project as well as the buyer, so check financing early, and tell your lender the complex’s name and address before you write an offer.

FHA. HUD keeps a searchable list of FHA-approved condominium projects by state, county, city, ZIP code or project name. If a project isn’t approved, FHA allows single-unit approval in some cases: the project must be complete and ready for occupancy, with at least five units, and within FHA’s concentration limit of 10% FHA-insured units in projects of ten or more units, or two units in smaller ones. The lender submits HUD’s Form HUD-9991 questionnaire.
VA. The association’s budget report must state whether the project is VA-approved.
Conventional. Lenders review the association’s budget, reserves, insurance and litigation, so a pending special assessment or lawsuit can slow or stop a loan.

Vacation rentals and leasing in a Napa condo

Don’t buy a condo in the city counting on short-stay income. The City of Napa treats any stay of fewer than 31 days as a vacation rental and caps permits at 41 non-hosted (whole-home) and 60 hosted under Napa Municipal Code section 17.52.515. All 41 non-hosted permits are taken and the non-hosted wait list is full.

Hosted permits are for owner-occupied homes: the owner must live there, sleep on site during rentals and rent no more than two bedrooms. The city took hosted applications from October 1 to 15, 2026 and selects permit holders by lottery.
HOA rules come first. The city’s hosted application has the owner certify that the property isn’t subject to association bylaws or CC&Rs that prohibit hosted use. Under Civil Code section 4741, an association can’t ban rentals outright or cap them below 25% of units, but it can prohibit rentals of 30 days or less.
Existing permits. A non-hosted permit can transfer to a new owner under section 17.52.515(f)(2), and the city accepts transfer applications at any time. If a seller markets one, confirm it with the city in escrow and make your contract depend on the transfer.

Longer leases are a different matter: check the CC&Rs for minimum lease terms and leasing rules. Silverado and the rest of unincorporated Napa follow county rules, which our post on vacation rental rules in Napa County explains.

Flood zones near the Napa River

The Napa River runs through the middle of the city, and the Napa River/Napa Creek Flood Protection Project is still being built. The county describes it as improvements to six miles of the river, from Highway 29 at the Butler Bridge and Southern Crossing to near Trancas Street, plus about a mile of Napa Creek upstream from the river.

Project element	Status (Napa County schedule)
Kennedy Park to Third Street floodplain and marsh terracing	Completed 2005
Maxwell Bridge (Imola Avenue) replacement	Completed 2005
Railroad bridges over the river and the bypass	Completed 2012
Napa Creek culverts and terraces	Completed 2013
Napa River dry bypass around the Oxbow	Completed 2015
Floodwalls north of the bypass	Design complete; construction completion estimated early 2028
Imola Avenue to Hatt Building floodwalls	In design; completion to be determined
Oxbow floodwalls	In pre-design; completion to be determined

For any complex near the river or Napa Creek, look up the address on FEMA’s Flood Map Service Center and note the zone and the map’s effective date, read the flood section of the natural hazard disclosure, and ask your lender early whether flood insurance will be required. Then compare that with the association’s flood coverage in its budget report. Our guide to flood zones in Sonoma, Napa and Marin explains the zones.

The same disclosure report shows whether the property is in a mapped fire hazard severity zone or a seismic hazard zone. For a complex on the hillier east or west edges of the city, check the fire maps and ask the association what its master policy covers; our guide to fire hazard severity zones in the North Bay explains what a zone means for a buyer.

Transfer tax, utilities and getting around

Transfer tax. Napa County charges documentary transfer tax at $0.55 per $500 of value, and a city inside the county receives half of what’s collected within its limits; the county page describes no separate city rate. On a $650,000 condo sale with no loan assumed, that’s 1,300 increments of $500, or $715. The county notes that the seller customarily pays in Northern California, but it’s negotiable and local custom varies; see our California transfer tax guide.

Sewer and water. Inside the city limits, water comes from the City of Napa, which draws on Lake Hennessey, Milliken Reservoir and the State Water Project. Napa Sanitation District says it serves over 75,000 customers in the City of Napa and surrounding unincorporated areas. In a condo, water, sewer and trash are often paid partly or wholly through the association, so check the budget to see which utilities are common expenses and which are billed to you.

Transit. VINE Transit runs local and regional bus routes from Napa; check its route list for the stops nearest a complex.

Selling a condo or townhome in Napa

A condo sale moves at the pace of the association’s paperwork. Order the section 4525 documents as soon as you decide to sell, since associations charge for them and buyers will ask for them before or with their offers. Have ready:

the current budget report, reserve study and insurance summary;
the FHA and VA status statements, and any pending special assessment;
the balcony and deck inspection report, and any repair plan;
the flood zone and any flood insurance history for the unit and the building; and
if you hold a non-hosted vacation rental permit, the city’s transfer requirements.

Price from sales in the same complex and similar ones nearby, adjusting for HOA dues, special assessments and financing status, not from detached homes. Our Napa County selling guide covers preparation and timing.

Questions people ask

Are there condos in downtown Napa?

Yes, though attached homes are a small share of the city’s housing. Units near downtown and the river trade on walkability; check each building’s flood zone and the status of the flood project floodwalls nearby.

Can I rent my Napa condo as a vacation rental?

Only with a city permit, and all 41 whole-home permits are taken. A hosted permit requires you to live in the unit and sleep there during rentals, and your association can prohibit rentals of 30 days or less.

Can an HOA in Napa ban rentals?

Not outright. Civil Code section 4741 bars associations from prohibiting rentals or capping them below 25% of units, but they can prohibit rentals of 30 days or less.

How do I know if a Napa condo is FHA-approved?

Search HUD’s FHA-approved condominium list by city or project name, and read the FHA statement in the association’s annual budget report. If the project isn’t approved, ask your lender about single-unit approval.

Do I need flood insurance for a condo near the Napa River?

It depends on the FEMA zone and your lender. Look up the address on FEMA’s flood map, read the association’s flood coverage in its budget report, and get a quote for your unit before you remove contingencies.

Is the Napa River flood project finished?

Not yet. The county lists the dry bypass, terraces and several bridges as complete, estimates the floodwalls north of the bypass will be finished in early 2028, and gives no completion date for the Imola-to-Hatt or Oxbow floodwalls.

Who pays transfer tax on a Napa condo sale?

By custom in Northern California the seller usually pays the county’s $0.55 per $500, half of which goes to the city for a sale inside city limits, but the contract can say otherwise.

Are Silverado condos in the City of Napa?

No. Silverado is in unincorporated Napa County, so county planning and vacation-rental rules apply there.

Thinking about a Napa condo or townhome, or selling one? We’ll pull the association documents, flood and financing status before you commit. Start with a home valuation or compare with our guide to Santa Rosa condos if you’re weighing Sonoma County too.

This is general information, not legal or tax advice; talk to a California real estate attorney about a specific association’s documents or rental rules.

Sources & notes

The housing-mix figures are from a 2015 city document using 2013 data and don’t separate condominiums; no current count of Napa condo units was found. Statute text was read on California Public Law because the Legislature’s site was unreachable.
