Metro Atlanta city guide · North Fulton County
Alpharetta, Georgia: the city, and the three ZIP codes that are not quite it
Alpharetta is an incorporated city of about 67,000 people in north Fulton County, roughly 26 miles from downtown Atlanta. It is also a mailing address worn by large parts of Milton, Johns Creek, Roswell and south Forsyth County, which are separate jurisdictions with their own taxes, their own services and in one case a different county entirely. Those distinctions change what you pay and which school your child attends, and almost nobody sorts them out before they start touring. This guide is about the city, and about how to tell when you are standing outside it.
Come as you are. Come on home.

Which Alpharetta are you looking at?
An Alpharetta address does not mean a house is in Alpharetta. Four ZIP codes carry the name and only part of what they cover sits inside the city limits. The answer changes your tax bill, your school assignment and which closed sales are actually comparable.
The City of Alpharetta is a municipality. It has its own mayor and council, its own police and fire departments and its own millage rate, and it occupies about 27 square miles of north Fulton County with a legal boundary drawn on a map. Its schools are run by Fulton County Schools, not by a city district.
An Alpharetta mailing address is a postal convention. It follows delivery routes, not city lines, and those routes were drawn before several of the neighboring cities existed. Milton and Johns Creek were both incorporated in 2006, long after the mail started arriving.
30004. The northern ZIP, and the one most likely to surprise you. It reaches across Fulton, Forsyth and Cherokee counties and covers a large share of the City of Milton. A Milton house with a 30004 address pays Milton taxes and is zoned to Milton schools.
30005. East and north east, and mostly not Alpharetta at all. Much of it is Johns Creek, and a good deal of the rest is south Forsyth County, which is a different county with a different school system and a different tax digest.
30009. The central and north western ZIP, closest to the historic core. This is the most reliably in-city of the four, though it also brushes Roswell and Milton at the edges.
30022. South eastern, and shared with Johns Creek. Two houses on facing sides of a street here can sit in different cities.
The parcel record settles it. Fulton County’s property search will tell you the taxing jurisdiction for a specific address, and Fulton County Schools’ address lookup will tell you the assigned elementary, middle and high school. Both take about a minute and both are free. If you are looking at Forsyth County, the lookup moves to Forsyth’s own system.
I check this on every house in these ZIP codes before I write an offer, and I would rather check it twice than explain it after closing. Halcyon is the clearest example of why: it is a well known destination with an Alpharetta mailing address and it sits in Forsyth County.

Orientation
Where Alpharetta sits, and who it borders.
Three of its four neighbors are incorporated cities in their own right, and the fourth is a different county. That is why the address question matters here more than it does almost anywhere else in the metro.
North: Milton
Incorporated in 2006, larger in land area than Alpharetta and much more rural in character, with horse properties, larger lots and a slower pace of development. Shares the 30004 ZIP code, which is where most of the confusion starts. Milton has its own millage rate and its own high school.
South and west: Roswell
Older than Alpharetta as a town and larger in population, with a historic district on the Chattahoochee and a housing stock that reaches further back in time. The two cities share a long border and a good deal of the same buyer pool, and Roswell generally gets you more house for the money.
South east: Johns Creek
Also incorporated in 2006, also sharing ZIP codes with Alpharetta, in this case 30005 and 30022. Largely residential, built out mostly in the 1990s and 2000s, with a reputation for schools that drives a lot of its demand.
North east: unincorporated Forsyth County
A county line, not a city line, which makes it the most consequential of the four. Different county government, different school system, different tax digest, and a large amount of newer construction. Halcyon sits on this side of the line with an Alpharetta mailing address.
What is actually here
Mostly 1990s subdivision, with newer density at the centers.
Alpharetta is not an old housing market pretending to be new. Most of it was built in one long run between the late 1980s and the mid 2000s, and the newest product is concentrated in a few deliberate places.
Large swim and tennis subdivisions. The dominant form. Four and five bedroom houses on a third of an acre or more, built between roughly 1988 and 2005, in communities with a pool, courts and a mandatory HOA. Windward is the best known of these, with a median build year around 1994 and an average single family house near 3,550 square feet, which is close to double the national average.
Estate and lakefront sections. Inside and alongside the big communities sit gated enclaves on larger lots, with lake or golf frontage, that trade well above the surrounding streets. In Windward these run into the millions while the ranch and traditional homes nearby sit far lower, which is why a single community median tells you very little.
Townhomes and condominiums at the centers. Newer, denser and attached, clustered around Avalon, the downtown core and the corridors near them. This is the product that did not exist here twenty years ago and it is what brings buyers who want to walk somewhere.
The original town. A small amount of genuinely old housing near the historic center, some of it renovated, much of it on smaller lots than anything built since. It is a thin slice of the market and it rarely comes up.
Square footage here is generous and the lots are real, which is the trade most buyers are making when they move out from the city. A house that would be a renovation project intown is frequently move in ready here at a similar price, with twice the space and a garage. What you give up is walkability outside a handful of districts, and a commute that is at the mercy of one highway.
Market snapshot
What Alpharetta homes are selling for.
Closed sales in Alpharetta for August 2026, from Redfin data. Prices here vary enormously by community and by which side of a city line a house sits on, so treat these as a starting point rather than a verdict on any one property.
Volume up, price flat, days on market steady and fewer than one in five selling above list. That is a market with real activity in it and very little panic, which tends to favor a prepared buyer who can move quickly without having to overpay to be heard.
The caution is the median itself. A $790,000 median covers a range that runs from townhomes well under it to estate properties several times above, and the city line problem means some of the comparable sales a portal shows you are not in Alpharetta at all. I pull comps by jurisdiction and by community, not by ZIP code.
Schools
How to research schools for an Alpharetta address.
Schools drive a large share of the demand here, and they are also where the address problem does the most damage. I do not rank schools or tell anyone which one is good. What I can do is make sure you are researching the right one.
There is no Alpharetta city school district. Fulton County Schools serves the city. That is different from Decatur, where an independent city district is one of the main reasons people buy there, and it is worth knowing if you are comparing the two.
The city sits in Fulton’s Learning Zone 7. The high schools in that zone are Alpharetta, Cambridge, Milton and the FCS Innovation Academy, which is an application based STEM school rather than a zoned one.
An Alpharetta address can be zoned to Milton High School. Or to a Johns Creek school, or to a Forsyth County school. The mailing address tells you nothing about the assignment, and a listing that names a school is reporting what someone typed into a field, not what the district says.
Boundaries move. Fulton has redrawn North Fulton attendance zones before and the district’s own Learning Zone map was under revision for the 2026 to 2027 year. Verify at the time you are buying, not from something written earlier.
Run the specific street address through Fulton County Schools’ address lookup, or Forsyth County Schools’ if the parcel turns out to be across the county line. That returns the assigned elementary, middle and high school for that parcel. Then, if a particular school is the reason you are buying, call the school and confirm. I would not rely on a portal, a listing remark or a neighborhood name for this, and I would not rely on me either without the lookup in front of us.
The walkable parts
Three centers, and only two of them are in the city.
Alpharetta spent twenty years building places to walk to, which is unusual for a metro Atlanta suburb and is a large part of why it commands the prices it does.
Avalon. An 86 acre mixed use development that opened in 2014 on Old Milton Parkway, with retail, restaurants, offices, a hotel and apartments in a tightly designed pedestrian setting. It draws from across North Fulton and beyond, which means weekend crowds and real energy, and also means parking is a consideration.
Downtown and City Center. The historic core around Main Street, reworked with a mixed use project holding about 74,000 square feet of retail and restaurants, 36,000 square feet of office, 168 apartments, green space, City Hall and a county library branch. Smaller and less polished than Avalon, and more of a neighborhood than a destination. The Alpha Loop, a paved multi use trail now past six miles, ties it to Avalon.
Halcyon. Opened in phases from 2019 along McFarland Parkway, with restaurants, boutiques, apartments and offices around a central lawn. It carries an Alpharetta mailing address and it is in Forsyth County. If a listing sells you on Halcyon, check the parcel before you check anything else.
In August 2026 the city council voted four to three to approve Jamestown’s plan to redevelop North Point Mall into a mixed use district built around an arena intended to attract an NHL team, with apartments, a hotel, restaurants, retail and a theater. The planning commission attached dozens of conditions, including one that no NHL franchise means no occupancy of the apartments.
No team has been awarded. A competing site in Forsyth County is pursuing the same franchise, and the city administrator has said Alpharetta is ready for redevelopment there with or without hockey. If an agent tells you to buy near North Point because of an arena, they are telling you about a condition precedent as though it were a fact. It may well happen. It has not happened.
Getting around
One highway, and five years of construction on it.
This is the section I would read first if I were moving here from somewhere with a train. Alpharetta’s access to the rest of the region runs almost entirely through GA 400, and GA 400 is in the middle of the largest project in its history.
GA 400 is the commute. Five of the project’s interchanges are in Alpharetta. There is no rail alternative today, and the surface roads that parallel 400 are not built to absorb it when it backs up.
The express lanes project is under way. Sixteen miles of tolled express lanes from the MARTA North Springs station north to past McFarland Parkway, delivered as a public private partnership, with construction beginning in the second quarter of 2026 and an expected opening in 2031. Expect lane shifts and disruption through that window.
Bus rapid transit is designed but not built. MARTA’s GA 400 BRT plan would run buses in the new express lanes from North Springs north, with four proposed stations beyond it: North Point Mall, Holcomb Bridge Road, Old Milton Parkway and Windward Parkway. Three of those four are in Alpharetta. The project status is design, and no opening date has been published.
MARTA buses, not trains. Alpharetta is served by MARTA bus routes and the Windward Parkway park and ride. Heavy rail has been studied for decades and has not been built.
The trails are genuinely useful. The Big Creek Greenway is a paved multi use trail along Big Creek, roughly eight miles between Windward Parkway and Mansell Road, with mountain bike trails and a wetland section. The Alpha Loop, begun in 2020, now runs past six miles and connects the downtown core to Avalon. People here commute to lunch on them, not just exercise on them.
If you work in Alpharetta, none of this is a problem, and a lot of people do: Fiserv, ADP, Verizon, Equifax, Jackson Healthcare, Morgan Stanley, Ernst and Young and Toyota Motor Credit all have large offices in the city, and it has been building fiber infrastructure since the 1980s.
If you work downtown or midtown, drive the commute at the hour you would actually drive it, on a weekday, before you commit. The map distance of 26 miles is not the number that will govern your life. And if you are buying with the express lanes or the BRT in mind, price the house on what exists now, not on 2031.
What you pay
Property taxes, and what the city rate buys.
An Alpharetta address outside the city limits pays a different bill from one inside it. This is the practical consequence of the boundary question and the one most people feel first.
A house in Milton, Johns Creek or Roswell with an Alpharetta mailing address pays that city’s millage, not Alpharetta’s, and a house in Forsyth County is on a different county’s digest entirely. Two listings at the same price can carry meaningfully different annual costs, and neither listing will tell you so.
Run the parcel. Then compare the full monthly number, including taxes and any HOA, rather than the price.
Straight talk
What agents get wrong about Alpharetta.
Most of these come from treating the ZIP code as the place, which is the single most common error in this market and the most expensive one.
Pulling comps by ZIP code. A 30004 comp set can include Milton and Forsyth County sales. A 30005 set is largely Johns Creek. If the comps that priced your offer, or your listing, were pulled by ZIP, they are describing a market your house is not in.
Quoting a school from the listing. School fields in a listing are typed by a person, and the person is frequently working from the mailing address. The district’s address lookup is the only version that binds.
Selling the arena. The North Point redevelopment was approved with a condition that an NHL franchise has to be awarded before the apartments can be occupied, and no franchise has been awarded. Treating it as settled is not optimism, it is a misstatement.
Treating HOA dues as the whole amenity bill. In Windward the lake club is a separate membership from the HOA, and buyers regularly assume one covers the other. Ask what the dues include, what they do not, and what the initiation and transfer fees are, in writing, before the due diligence period runs out.
Quoting the drive from a map. Twenty six miles to downtown is a measurement, not a commute. With construction on GA 400 running into 2031, the honest answer to how long it takes is that you should drive it yourself at your own hour.
Describing the whole city as new. The bulk of the housing stock went up between the late 1980s and the mid 2000s. A 1994 house is not a new house, and at thirty years old it is at the age where roofs, systems and original windows start coming due. Inspect accordingly.
An honest accounting
The trade offs, stated plainly.
I would rather you decide against Alpharetta for the right reason than move here and find out what you traded.
What you gain
Space, and a lot of it. Houses near 3,500 square feet on a third of an acre are ordinary here rather than exceptional. Two genuinely walkable districts, which is rare in a metro Atlanta suburb. A large employment base inside the city, so the commute is optional for many people. Trails that connect real destinations. A city government with a stable millage rate and a strong services reputation.
What you trade
Dependence on one highway, currently under a five year rebuild. Price: the median is well above the metro and above most of what you would pay for comparable space elsewhere. A boundary problem that affects taxes, schools and comps and that you have to manage actively. Outside Avalon, downtown and the trails, a car for everything. And a housing stock that is mostly thirty years old wearing the look of something newer.
In context
How Alpharetta compares to the alternatives people actually weigh.
Nobody shops Alpharetta on its own. These are the comparisons that come up in my consultations, with the honest version of each.
Against Roswell. Older, larger, with a historic core on the river and generally more house for the money. If the budget is the binding constraint and the schools work, Roswell deserves a serious look before you settle on Alpharetta. Read the Roswell guide →
Against Milton. More land, more rural character, higher prices at the top end and far less to walk to. People who want acreage choose Milton. People who want to walk to dinner choose Alpharetta. Read the Milton guide →
Against Johns Creek. Very similar housing stock and vintage, built by many of the same hands in the same years, with a school driven buyer pool. The main difference is that Alpharetta has commercial centers and Johns Creek largely does not.
Against East Cobb. The other large north side school market, generally lower in price, on the other side of the river and a different county, with its own highway problem on I 75. Worth running both if the school is the goal and the employer is flexible.
Against staying intown. This is the one I get asked most. Intown you pay for walkability, age and proximity. Here you pay for space, schools and newness. At the same number you get a very different house and a very different week. I have lived on both sides of that line and I will not pretend one answer fits everyone.

For sellers
Own a home in Alpharetta?
The same boundary that confuses buyers is what makes an automated estimate unreliable on your house. A tool that cannot tell which side of the line an address sits on cannot select the right comparable sales for it.
What I can tell you
Which sales are genuinely comparable to your house once they are matched on jurisdiction, product type, age, condition and where in the city you are, and what is actually competing with you right now. Not a postal-city average, not a ZIP-level figure, and not a headline number drawn from a sample too small to describe your street.

Common questions
Alpharetta FAQ
Seven questions buyers and sellers actually ask about this city.
Often, but far from always. Four ZIP codes carry the Alpharetta name and they extend into Milton, Johns Creek, Roswell and Forsyth County. The 30004 ZIP covers a large share of Milton and reaches into Forsyth and Cherokee counties. The 30005 ZIP is mostly Johns Creek and south Forsyth. The only way to settle it is to look up the parcel in the county property records, which takes about a minute.
No. Fulton County Schools serves the city, and Alpharetta sits in the district’s Learning Zone 7 along with Milton and Cambridge high schools and the application based Innovation Academy. An Alpharetta address can be zoned to Milton High School, to a Johns Creek school or to a Forsyth County school, so the only reliable method is the district address lookup for the specific property.
The median sale price in August 2026 was about $790,000, down 1.6 percent from a year earlier, with a median of 37 days on market and 261 homes sold. Homes sold at about 98.7 percent of list on average and fewer than one in five sold above asking. The range behind that median is wide, so a figure for a specific community is more useful than a figure for the city.
Alpharetta is about 26 miles from downtown, almost all of it on GA 400, and the time varies enormously by hour. GA 400 is also in the middle of a 16 mile express lanes project that began construction in the second quarter of 2026 and is expected to open in 2031, so there will be disruption for several years. If the commute matters to your decision, drive it yourself at the hour you would actually be driving it before you commit.
Not as heavy rail, which has been studied for decades without being built. MARTA has designed a bus rapid transit line that would use the new GA 400 express lanes, running north from the North Springs station with four proposed stations: North Point Mall, Holcomb Bridge Road, Old Milton Parkway and Windward Parkway. Three of those would be in Alpharetta. The project is in design and there is no published opening date, so I would not price a house on it.
In August 2026 the city council voted four to three to approve a Jamestown redevelopment plan centered on an arena intended to attract an NHL team, alongside apartments, a hotel, retail, restaurants and a theater. The approval came with dozens of conditions, one of which is that an NHL franchise must be awarded to the site before the apartments can be occupied. No team has been awarded, and a competing site in Forsyth County is pursuing the same franchise. It may happen. It has not happened yet.
The City of Alpharetta millage rate for 2026 is 5.750 mills, unchanged from the prior year, made up of 5.000 for general government and 0.750 for debt service. Fulton County and Fulton County Schools levy separately on top of that. The basic homestead exemption takes $45,000 off the assessed value for the city levy, and a floating homestead exemption caps taxable value growth at the lower of three percent or the consumer price index. A house with an Alpharetta address that sits in Milton, Johns Creek, Roswell or Forsyth County pays that jurisdiction’s rate instead.
Find out which jurisdiction you are standing in before you fall for the house.
Whether you are buying in Alpharetta, selling here, or weighing it against Roswell, Milton, Johns Creek or somewhere back inside the perimeter, the useful conversation starts with the parcel, the school assignment and the right comparable set, not with a number attached to a mailing city.
