Almost everyone gets this backwards. People assume USDA eligibility works like city limits: inside Augusta, no; outside Augusta, yes. It does not work like that at all, and in our area the difference is expensive.

USDA maintains a mapped ineligible areas layer, and the boundary is drawn around urbanized areas, not municipal borders. Around Augusta that boundary reaches well past anything you would call the city, and it leaves out places you would swear are the country.

What the map actually says around Augusta

On September 18, 2026 we queried USDA Rural Development's own published ineligible-areas layer, the same dataset that sits behind the public eligibility map, at points across the CSRA. Here is exactly what came back that day.

Inside the ineligible zone: Augusta, as expected. Also Hephzibah and Blythe. And heading west, the polygon covers Martinez, Evans and Grovetown in Columbia County.

Outside it, in eligible rural territory: Harlem in western Columbia County, Thomson and Dearing in McDuffie, Waynesboro in Burke, Lincolnton in Lincoln.

The single polygon covering the whole Augusta side of that list carries a USDA effective date of July 25, 2023, so this particular line has held for a while. That is not the same as saying it will hold.

The line runs down the middle of a road, not around a town

Here is the part that should make you check your own parcel rather than a rule of thumb. We ran that same layer along entire roads in the 30815 ZIP, the Hephzibah mailing area, a few miles apart. They do not agree with each other.

Hephzibah McBean Road came back ineligible from one end to the other, every point we sampled, out through the Richmond County countryside toward McBean. Springhill Church Road, which runs south out of the Keysville Road area and into Burke County, came back eligible from one end to the other.

Farmers Bridge Road is the one that splits. The northern couple of miles, the stretch that is inside Richmond County and inside Hephzibah city, sat within the ineligible polygon. The boundary then crossed the road, and every point we sampled south of that crossing, all the way down the Burke County stretch past Keys Lane, came back eligible. One road, one name, two answers, and the crossing is under a mile long.

Same town name on the mail. Same ZIP code. Same view out the windshield. Opposite answers.

That matters to us directly, because the Burke County end of Farmers Bridge Road and the roads around it are where our own home site pipeline runs. On September 18, 2026 that ground sat on the eligible side of the line while Hephzibah city, four or five miles up the same road, did not. A Hephzibah mailing address by itself tells a buyer nothing in either direction. The parcel decides.

USDA's own metadata on that layer says the data "is updated based on the Ineligible Area changes sent in from the USDA state offices" and that it "changes often." Everything above is what the layer returned on one day, September 18, 2026. It is a snapshot, not a promise about any parcel, and it can move without notice. Run your own address through the USDA eligibility tool before you plan around it, and confirm it with your lender. If the tool returns "Unable to Determine," the handbook requires the lender to check with USDA staff before ordering an appraisal.

Why the line lands where it does

The definition comes from section 520 of the Housing Act of 1949. In general, a rural area is open country not part of or associated with an urban area, or a town under 10,000 that is rural in character, or a place outside a Metropolitan Statistical Area with a population between 10,000 and 20,000 that has a serious lack of mortgage credit, with grandfathering that can carry certain areas up to 35,000 through the 2030 census.

Two phrases explain our map. Augusta sits in an MSA, and "associated with an urban area" does a lot of work. A parcel can be surrounded by pine timber and still count as part of the Augusta urbanized area's footprint. USDA reviews these designations every five years, and every three years in fast-growing areas and in eligible communities inside MSAs, which is exactly what Columbia County is.

The manufactured home rules, and the one that changed in 2025

An eligible address is only half the question. USDA has its own requirements for the home, set out in 7 CFR 3555.208 and Chapter 13 of handbook HB-1-3555.

For a new unit:

  • It must be a new unit in stock that "has never been installed or occupied at any other site or location," and may be moved only from the manufacturer's or dealer's lot to the site being financed.
  • The manufacture date must be within 12 months of the date of loan closing. This is the one that changed. Until a final rule took effect on March 4, 2025, the 12-month test ran from the purchase contract. A great deal of advice online still says "purchase agreement dated within 12 months of manufacture." That language is out of date.
  • Floor area of not less than 400 square feet. There is no minimum width rule we could find, and the handbook expressly contemplates "single- or multi-width units."
  • It must be placed on a permanent foundation built to FHA guidelines, which USDA identifies as the Permanent Foundations Guide for Manufactured Housing, HUD-4930.3G. Certification of a proper foundation is required.
  • All wheels, axles, towing hitches and running gear must be removed. A unit with a tow hitch or running gear still attached is an ineligible loan purpose.
  • The HUD certification label and data plate have to be there and legible.

For an existing unit there is good news that has not filtered down. USDA used to run existing manufactured home financing as a limited pilot; the same January 2025 final rule made it permanent and nationwide. An existing unit can qualify if it has never been previously installed on a different homesite, has no alterations since the factory other than engineered or code-inspected additions, sits on a certified permanent foundation, is at least 400 square feet, and has a manufacture date within 20 years of the date of loan closing. That last one is a hard stop.

The title has to disappear

Under 7 CFR 3555.208(f), the loan must be secured by "a perfected lien on real property consisting of the manufactured home and the land," the home "must be taxed as real estate as applicable under State law," and where state law permits, "any certificate of title to the manufactured home must be surrendered." The handbook is blunt about the alternative: "A combination of a chattel and real estate mortgage is not acceptable."

On a new Georgia land-home package this is cleaner than people expect. A brand new home that was never titled goes into the real estate records on a certificate of permanent location with the manufacturer's certificate of origin attached. There is no title to surrender because one was never issued.

The site

USDA does not cap your acreage. Handbook Chapter 12 says plainly that "there is no specific limitation to the size/acreage of the site," though the appraiser has to explain how the subject compares to other single family sites in the area.

What it does restrict is income production. Under 7 CFR 3555.201(b), the site "must not include income-producing land or buildings to be used principally for income-producing purposes," and "vacant land without eligible residential improvements, or property used primarily for agriculture, farming or commercial enterprise is ineligible." A retired barn used for storage is fine. An operating commercial poultry setup is not. And you cannot use USDA to buy the dirt by itself: a loan will not be guaranteed if used "to purchase a site without also financing a new unit."

Income limits and fees, without made-up numbers

Household income limits exist, based on adjusted annual income for everyone living in the home, and they vary by county and household size. USDA publishes a lookup on the same eligibility site. We are not printing a dollar figure here, because a stale number in an article is worse than no number.

Same for fees. USDA charges an upfront guarantee fee and an annual fee and sets both by fiscal year. Regulation caps them at 3.5 percent upfront and 0.5 percent annually under 7 CFR 3555.107, but the actual rates are announced annually and the federal fiscal year turns over October 1. Ask your lender for the current year's numbers in writing.

What we do with all this

Before we put a home site on the list we know which side of that line it is on, because it changes who can buy it and on what terms. If USDA is off the table for a parcel, the same package on the same permanent foundation is generally set up for VA, FHA or conventional financing instead, which is why we build them that way. Our financing page walks through the four programs side by side.

If you are looking at a specific address, ours or somebody else's, run it through the USDA tool and then talk to a lender. And if you want to know which of our current home sites fall on the eligible side today, ask and we will check it with you rather than guess.

This article is general information, not a loan approval, a commitment to lend, or a determination about any specific property. USDA eligibility boundaries, income limits, fees and handbook provisions change, and USDA states its ineligible-areas dataset changes often. Verify any address at the official USDA eligibility site and confirm program terms with a qualified lender.
