USDA Rural Development Single-Close ConstructionBuild in a rural or small-town area with no down payment
A USDA construction-to-permanent loan lets moderate-income buyers finance 100% of a ground-up build in a USDA-eligible rural or small-town area — the land, the construction, and the permanent mortgage in one closing. North Bay Capital checks the eligibility map, the income limits, and the math before you fall in love with a lot.
A USDA construction loan is a single-close, construction-to-permanent mortgage backed by USDA Rural Development's Section 502 Guaranteed program. It offers 100% financing — $0 down — to build a primary residence in a USDA-eligible rural or small-town area, with no separate construction loan and refinance. Household income has to stay within the moderate-income limit (roughly 115% of area median, county-specific), and the property has to be in an eligible area. Many communities outside the urban cores of Sonoma, Lake, Mendocino, and Napa counties qualify.

USDA Single-Close Construction-to-Permanent Loan (Section 502 Guaranteed)
100% financing for a ground-up rural build, in a single closing.
This combines two things people usually think of separately: the $0-down USDA Section 502 Guaranteed loan and a construction loan. You close once, build the home with staged draws, and the loan converts to a permanent 30-year fixed USDA mortgage when it's finished — no down payment, no second application, and no separate refinance. The guarantee that USDA provides to the lender is what lets you finance 100% of the appraised value on a brand-new home.
The honest caveat: single-close USDA construction is a specialty product, and only a limited number of lenders offer it even though USDA's program allows it. That's where working with a broker matters — North Bay Capital isn't limited to one bank's menu, so we can place your file with a lender that genuinely does USDA construction. Two eligibility boxes have to tick: the property has to sit in a USDA-eligible area (most communities outside the urban cores near Sonoma County qualify), and your household income has to stay within the county's moderate-income limit.
- Moderate-income buyer building in a rural Sonoma, Lake, or Mendocino County town
- First-time builder with no down payment saved who meets the income limit
- Buyer who'd qualify for FHA construction but wants to skip the down payment
- Household building outside the metro cores where USDA-eligible land is affordable
USDA Construction Eligibility & New-Build Requirements
The map, the income limits, and the new-construction standards — checked up front.
Two gates decide whether a USDA construction loan is even on the table, and we check both before you spend a dime on plans. First, location: the parcel has to fall inside a USDA-eligible rural area, which you can look up on USDA's eligibility map. A lot of people are surprised how much of Northern California qualifies — plenty of small towns and outlying areas near Sonoma County are eligible even though they don't feel 'rural.' Second, income: your total household income has to stay within the moderate-income limit for the county, which is roughly 115% of the area median but set specifically by location and household size.
New construction carries a few extra USDA requirements beyond a standard purchase. The build generally needs to meet thermal and energy standards, use a qualified licensed builder who provides a warranty, and pass USDA's inspection milestones during construction. We line up the plans, the builder documentation, and the appraisal so the file sails through underwriting — and if the lot or your income doesn't fit USDA, we'll tell you straight and pivot to FHA or conventional construction instead.
- Buyer verifying a specific lot's USDA eligibility before making an offer
- Household near the income limit who needs the exact county figure checked
- Builder and buyer coordinating USDA's new-construction inspection schedule
- Buyer comparing a USDA build against FHA when the lot is borderline eligible
Calculators for this loan
What people ask before they apply
Can I build a home with no money down using a USDA loan?
Yes, in an eligible area and within the income limits. A USDA single-close construction loan finances 100% of the appraised value, so there's no down payment. You'll still have closing costs and the USDA guarantee fee, but the upfront fee can be financed into the loan. The two gates are location (the lot has to be in a USDA-eligible rural area) and household income (within roughly 115% of the county's area median).
Which areas near Sonoma County qualify for a USDA construction loan?
More than most people expect. USDA eligibility is about the census-designated area, not how 'rural' a place feels, so many small towns and outlying communities in and around Sonoma, Lake, Mendocino, and Napa counties qualify — generally the areas outside the urban cores of Santa Rosa and Petaluma. We check the exact parcel against USDA's eligibility map before you make an offer.
What are the income limits for a USDA construction loan?
USDA caps household income at the moderate-income limit for the county, which is roughly 115% of the area median income but set specifically by location and household size. The limit rises with the number of people in your household. Because the figures are county-specific and updated periodically, we pull your exact limit before you count on the program.
Is a USDA construction loan one closing or two?
The product we focus on is a single-close, construction-to-permanent loan. You close once, build with staged draws, and the loan converts automatically to a permanent 30-year USDA mortgage when the home is finished — no second application and no separate refinance. Not every lender offers single-close USDA construction, so as a broker we specifically shop for the ones that do.
Why is it hard to find a USDA construction loan?
USDA's program allows single-close construction, but it's operationally involved — managing draws, inspections, and the new-build standards on top of USDA's own guarantee process — so only a limited number of lenders offer it. That's the main reason to use a broker. North Bay Capital isn't tied to one bank's product list, so we can place your file with a lender that genuinely funds USDA construction loans.
What credit score do I need for a USDA construction loan?
Most lenders want a 640 mid-score to use USDA's streamlined automated underwriting path. Lower scores can sometimes work through a manual underwrite in the right scenario, but a construction loan adds complexity, so a 640+ makes the file much smoother. We'll review your credit early and tell you where you stand.
Does the home have to be my primary residence?
Yes. USDA financing — construction included — is strictly for owner-occupied primary residences. It can't be used for a second home, a vacation property, or a rental. You're expected to occupy the home once construction is complete.
What extra requirements does USDA have for new construction?
Beyond a standard purchase, a USDA new build generally has to meet thermal and energy-efficiency standards, use a qualified licensed builder who provides a warranty, and pass USDA's inspection milestones during construction. We coordinate the plans, builder documentation, and appraisal so these requirements are handled up front rather than discovered mid-build.
