Danville and Alamo sit side by side in the San Ramon Valley, close enough that a single home search can cover both. They share a fire district and a school district. The real difference is government: Danville is an incorporated town that runs its own permits and zoning, while Alamo is an unincorporated community where Contra Costa County does that work.
That difference rarely shows up in a listing. It matters most when you plan to remodel, add a unit or question a neighbor’s project, because it decides which office you call and which rules apply.
Key Takeaways
– Danville voted to incorporate in 1982 and runs its own Permit Center (Town of Danville).
– Alamo is unincorporated, so county staff handle permits, planning and code enforcement (Contra Costa County).
– Both share San Ramon Valley Fire Protection District and San Ramon Valley Unified School District.
– The Census Bureau puts Danville’s median home value at $1,681,700 and Alamo’s at $2,000,000 or more.
What is the difference between Danville and Alamo?
Danville is a town with its own local government, and Alamo is not. The Town of Danville’s history page says residents voted to incorporate in 1982, “allowing themselves to shape future changes more directly.” Alamo remains unincorporated: Contra Costa LAFCO describes the area served by its park district as the “unincorporated Alamo community.”
Before 1982, the two were in the same position. A Contra Costa LAFCO staff report notes that County Service Area R-7 was formed in 1971 to provide parks to “Alamo and Danville (unincorporated at the time).” Danville later incorporated. Alamo did not.
In practice, Danville’s zoning, permits and town services are decided by the Town. Alamo’s sit with Contra Costa County and its Board of Supervisors.
| Danville | Alamo | |
|---|---|---|
| Local government | Incorporated town (1982) | Unincorporated; Contra Costa County, advised by the Alamo MAC |
| Building permits and planning | Town of Danville Permit Center | County Department of Conservation and Development |
| Police | Town contract with the Contra Costa County Sheriff’s Office | Sheriff’s Valley Station, 150 Alamo Plaza |
| Fire | San Ramon Valley Fire Protection District | San Ramon Valley Fire Protection District |
| Public schools | San Ramon Valley Unified School District | San Ramon Valley Unified School District |
Neither arrangement is better in the abstract. What matters is whether the office in charge will approve the plans you have for the property.
Who issues building permits and handles zoning in each?
In Danville, the Town’s Permit Center issues building permits for addresses inside the town boundary. In Alamo, Contra Costa County’s Department of Conservation and Development handles both planning applications and building permits. If you’re buying a home you plan to change, this is the first thing to pin down.
Danville: check the town boundary first
The Town of Danville’s Permit Center FAQ asks applicants to confirm that the job site is “within the Town of Danville’s town boundary.” If it is not, “your address is under the County of Contra Costa jurisdiction.” Run that check before you rely on any remodel plans for a home.
The Town publishes its own zoning map, a separate downtown zoning map and its General Plan and Housing Element. Its permit desk is (925) 314-3330. Danville also sets its own construction hours: 7:30 a.m. to 7:00 p.m. on weekdays, and 9:00 a.m. to 7:00 p.m. on weekends and holidays. Projects that went through discretionary review can have tighter hours.
Alamo: the county does planning, permits and enforcement
Contra Costa County’s permit information page says its Department of Conservation and Development is responsible for planning applications and building permits. Applications for building, planning and public works go through the county’s online ePermits Center.
The county explains the planning side plainly: planning “determines what uses you can place on your property and how the development conforms to community plans, including design of the development.”
Code enforcement follows the same line. The county’s Alamo page states that code enforcement in Alamo is “managed exclusively by the County Department of Conservation and Development.” The county adds that no outside group has the authority to enforce local ordinances or issue citations.
For a buyer, the practical step is asking for the permit history. The Town of Danville offers a permit history search for Danville addresses, and Contra Costa County issues permits for Alamo. Danville was unincorporated until 1982, so for an older home ask both offices where earlier permits are kept.
How do police and fire services compare?
Fire service is the same in both, and police service comes from the same agency through different arrangements. According to the Town of Danville’s fire services page, the San Ramon Valley Fire Protection District covers about 155 square miles, including Alamo, the Town of Danville and the City of San Ramon. The Town describes it as an autonomous special district.
For policing, the Town of Danville says its primary public safety services are contracted with the Contra Costa County Sheriff’s Office and the San Ramon Valley Fire Protection District. Alamo, as an unincorporated area, is served by the Sheriff directly.
The Sheriff’s Valley Station is at 150 Alamo Plaza #C in Alamo. It patrols more than 250 square miles, including all unincorporated area south to the Alameda County line. The station page also lists five deputies assigned to four specially funded districts, one of which is Alamo.
For a buyer, the difference is administrative. Danville’s police service runs through a town contract. Alamo’s comes from the Sheriff’s Valley Station, with deputies assigned to its specially funded district.
Who has a voice on local decisions in Alamo?
Alamo residents have a Municipal Advisory Council (MAC) rather than a council of their own. According to the county’s Alamo page, the MAC “was formed in 2009 and advises the Board of Supervisors on services that are or may be provided to the Alamo community.”
Its advisory scope is broad. The county lists parks and recreation, lighting and landscaping, public works, code enforcement, land use and planning, and transportation. The MAC meets on the first Tuesday of each month at 6:00 p.m. at the Alamo Women’s Club, 1401 Danville Blvd.
Those agendas are worth a look before you buy. The county’s MAC page posts upcoming items, including land-use applications on Alamo addresses, so a quick scan can show you what is proposed near a home you’re considering. In Danville, the equivalent is the Town’s own planning process.
Do Danville and Alamo share schools and parks?
They share a school district but not a park system. San Ramon Valley Unified School District says it serves “the communities of Alamo, Blackhawk, Danville, Diablo, and San Ramon,” along with small parts of Walnut Creek and Pleasanton.
Being in the same district doesn’t mean every home goes to the same school. Assignment depends on the address, so confirm it with the district for the specific property before you write an offer.
Parks split along the town line. In Alamo, County Service Area R-7A, also known as Alamo Parks & Recreation, handles park maintenance, improvements and events. Its list includes:
- Andrew H. Young Park
- Hap Magee Ranch Park
- Livorna Park
- the Alamo School and Rancho Romero school sports fields, open to the public only after school hours
Contra Costa LAFCO describes the area served by County Service Area R-7 as the unincorporated Alamo community, so Danville addresses fall outside it.
How do home values and the housing stock compare?
Alamo’s median home value is higher, and its homes are spread over less land at lower density. The U.S. Census Bureau’s QuickFacts puts the median value of owner-occupied homes at $1,681,700 in Danville for 2020-2024. For Alamo, the Census reports only “$2,000,000+,” the top of its published range.
Here is how the two compare on the Census Bureau’s own figures:
| Measure (U.S. Census Bureau) | Danville | Alamo |
|---|---|---|
| Median value of owner-occupied homes, 2020-2024 | $1,681,700 | $2,000,000+ |
| Owner-occupied housing unit rate, 2020-2024 | 85.5% | 91.8% |
| Population, 2020 Census | 43,582 | 15,314 |
| Land area, 2020 (square miles) | 18.08 | 9.82 |
| Population per square mile, 2020 | 2,410.8 | 1,560.1 |
Three readings follow from those numbers:
- Alamo is less dense, with about 1,560 residents per square mile against Danville’s 2,411.
- Alamo has proportionally fewer rentals: almost 92% of its occupied homes are owner-occupied, against 85.5% in Danville.
- Danville is the larger community. The Census counts 15,545 households in Danville against 5,070 in Alamo (2020-2024).
Medians are blunt tools, though. A top-coded figure like Alamo’s tells you the middle home is worth more than $2 million, not how much more. For a real price read on a specific street, look at recent comparable sales.
What does the commute look like from each?
Commute times from the two are close. The Census Bureau reports a mean travel time to work of 32.5 minutes for Danville workers and 29.2 minutes for Alamo workers, based on 2020-2024 survey data.
That gap is small, and it reflects where residents actually work rather than a fixed drive. Your own commute depends on your destination and the time you leave. Before you commit, run your actual route at your actual hour.
What should you check before making an offer?
The most useful step is confirming which government a property falls under, because everything else follows from it.
- Confirm the jurisdiction. Use Danville’s town boundary check or call the Town’s permit desk at (925) 314-3330. If the address is outside the town, it falls under the county.
- Ask for the permit history. Start with the Town for a Danville address and the county for Alamo. Danville was unincorporated until 1982, so for an older home confirm with both offices where earlier permits are kept. Unpermitted work is easier to raise before closing than after.
- Read the relevant zoning. Danville publishes its zoning maps. For Alamo, the county’s planning staff can tell you what the zoning allows.
- Scan recent Alamo MAC agendas. If the home is in Alamo, upcoming land-use applications can flag nearby projects.
- Confirm the school assignment for the exact address with San Ramon Valley Unified.
- Review the tax bill. Property tax and special assessments vary by parcel. Our Contra Costa County property tax guide covers the county-wide basics.

Frequently Asked Questions
Is Alamo part of Danville?
No. Danville is an incorporated town with its own government, incorporated by a 1982 vote. Alamo is an unincorporated community, so Contra Costa County provides its local government services and a Municipal Advisory Council advises the county’s Board of Supervisors. The two share the San Ramon Valley Fire Protection District and San Ramon Valley Unified School District.
Who issues building permits in Alamo?
Contra Costa County’s Department of Conservation and Development issues planning approvals and building permits for Alamo, and applications go through the county’s online ePermits Center. The same department handles code enforcement in Alamo. In Danville, the Town’s own Permit Center issues permits for addresses inside the town boundary.
Do Danville and Alamo have the same schools?
Both are served by San Ramon Valley Unified School District, which also covers Blackhawk, Diablo and San Ramon. Which school a home is assigned to depends on the specific address, so confirm it with the district before you write an offer rather than relying on a listing description or a town name.
How do home values in Danville and Alamo compare?
The Census Bureau’s 2020-2024 estimate puts the median value of owner-occupied homes at $1,681,700 in Danville. For Alamo it reports only $2,000,000+, the top of its published range. Medians describe a whole community, so a specific street can sit well above or below either figure.
