Yes, you can get a loan to build a garage, and several products are built for exactly this kind of project. The right one depends on how much the build will cost, how much equity you already have in your home, and whether you’re willing to put the house up as collateral. Personal loans, home equity loans, HELOCs, construction-to-permanent loans, and FHA 203(k) rehabilitation loans all fit different situations.
Start With the Price Tag
A single-car garage runs roughly $18,000 to $23,000 in 2026, and a two-car garage typically lands between $35,000 and $45,000. Attached builds come in lower because they share a wall, foundation, and roofing with the house. Detached garages cost more since they need their own foundation, framing, and electrical runs. Insulation, drywall, epoxy floors, or a workshop area push the number higher.
Project size drives loan choice. A $20,000 build can work well on an unsecured personal loan. A $50,000 build with custom features starts to justify the closing costs and paperwork of a home equity product. Get at least two detailed contractor bids before you apply so you have a defensible number when the lender asks how much you need.
Loan Options for a Garage Build
Personal Loans
An unsecured personal loan is the simplest path. You borrow a fixed amount, get it as a lump sum, and repay in equal monthly installments. No collateral, so the lender can’t take your house if you default. The trade-off is cost. Rates range from about 6% to over 30% depending on your credit, and terms usually run two to seven years, which means higher monthly payments than a home equity product stretched over 15 or 20 years. For smaller projects under $25,000 where you’d rather keep your house out of it, a personal loan makes sense.
Home Equity Loans
A home equity loan is a second mortgage. You borrow against the equity you’ve built, get one lump sum, and repay at a fixed rate over 5 to 20 years. Because the house secures the debt, rates are considerably lower than personal loans. Average home equity loan rates sit around 8% in early 2026, and strong credit can do better. The risk is real: miss enough payments and the lender can pursue foreclosure. When you know the total cost upfront and want predictable payments, this option is hard to beat.
Home Equity Lines of Credit
A HELOC works more like a credit card secured by your home. The lender approves a maximum limit, and you draw against it as needed during a set borrowing window. You pay interest only on what you actually use, which helps when construction costs arrive in stages. Most HELOCs start with a draw period, then move into a repayment period where the remaining balance is paid down on a fixed schedule, often 10 to 15 years.1Consumer Financial Protection Bureau. What You Should Know About Home Equity Lines of Credit Some HELOCs require the entire balance as a single balloon payment at the end, so read the terms. If your project might see cost overruns or phased contractor billing, that draw-as-needed flexibility beats a lump sum.
Construction-to-Permanent Loans
For larger or more complex builds, a construction-to-permanent loan starts as short-term financing that covers the building phase, then converts into a standard long-term mortgage once construction is finished.2Fannie Mae. Conversion of Construction-to-Permanent Financing Overview Conversion usually requires local building officials to sign off that the structure is safe and complete. The single closing saves money over taking out a construction loan and refinancing separately, since you avoid paying two sets of closing costs. Expect more paperwork, tighter underwriting, and a longer timeline. These make the most sense when the garage is part of a broader renovation or when the build itself will take several months.
FHA 203(k) Rehabilitation Loans
If you’re buying a home that needs a garage, or combining a garage with other renovations, an FHA 203(k) rolls improvement costs into your mortgage. The Limited 203(k) covers projects up to $75,000. The Standard 203(k) handles larger work with a minimum project cost of $5,000 and supports structural additions, which fits new garage construction.3HUD.gov. 203(k) Rehabilitation Mortgage Insurance Program Types FHA loans carry mortgage insurance premiums and require the property to meet FHA appraisal standards, but they allow lower down payments and more flexible credit than conventional options.
What Lenders Want to See
Debt-to-Income Ratio
Lenders compare your monthly debt payments to your gross monthly income. Most want the ratio below 43%. If you earn $5,000 a month, your total monthly debts including the new garage loan should stay under roughly $2,150. Some lenders cap it at 36%. FHA products allow up to 43% total debt and 31% specifically toward housing. Lower ratios improve both your approval odds and your rate.
Credit Score
Minimums depend on the product. Online personal lenders sometimes accept scores in the low 600s, but the rate at that level will be steep. Home equity products and construction loans generally want at least 620, with many lenders preferring 660 or higher. Above 740 unlocks the best rates across the board. If your score is borderline, paying down credit card balances for a few months before applying can meaningfully improve both the approval decision and the offered rate.
Equity Requirements
Home equity loans and HELOCs typically require you to keep at least 15% to 20% equity in the home after the new borrowing. Say your home appraises at $400,000 and you owe $300,000. You have $100,000 in equity. A lender requiring 20% equity retention would let you borrow up to $20,000 against the house. Thin equity means either denial or a requirement to carry private mortgage insurance, which adds to your monthly cost.
The Paperwork
Lenders verify income. Salaried borrowers should have the most recent 30 days of pay stubs and the last two years of W-2s ready. Self-employed borrowers should expect to provide two years of signed federal tax returns with all schedules and business filings.4Fannie Mae. Underwriting Factors and Documentation for a Self-Employed Borrower Fannie Mae allows one year of returns in limited cases, but only when the business has operated at least five years. Lenders also want a two-year employment history.
On the project side, prepare a detailed contractor bid breaking down materials, labor, permits, and a projected timeline. Architectural drawings or site plans help the lender assess how the garage affects the property’s value. Your current homeowners insurance policy will also go on file.
For home equity products, the primary application is the Uniform Residential Loan Application, Fannie Mae Form 1003, which captures income, assets, debts, and employment.5Fannie Mae. Uniform Residential Loan Application (Form 1003) Everything on it must be accurate. Submitting false information on a federal loan application is a federal crime under 18 U.S.C. § 1014, punishable by up to 30 years in prison and fines up to $1 million.6Office of the Law Revision Counsel. 18 USC 1014 – Loan and Credit Applications Generally Lenders verify the numbers you submit, and discrepancies trigger fraud investigations.
From Approval to Money in Hand
After you apply, an underwriter reviews everything against lending standards. Secured products require a professional appraisal to determine current market value and, sometimes, the projected value with the completed garage. Appraisal fees typically run $350 to $550, paid upfront.
At closing you sign the loan agreement and legal disclosures. Closing costs on home equity products generally run 2% to 5% of the loan amount, so a $50,000 loan carries roughly $1,000 to $2,500 in costs. Personal loans usually have no closing costs but may charge an origination fee of 1% to 8%, deducted from the disbursement.
How you get the money depends on the product. Personal loans and home equity loans deposit the full amount into your bank account, usually within a few business days of closing. HELOCs let you draw as needed. Construction loans release funds on a draw schedule tied to project milestones, with a percentage released after an inspection confirms each phase is complete. That structure protects the lender from funding a stalled project and protects you from paying a contractor in full before the work is done.
You Can Cancel a Home-Secured Loan Within Three Days
Sign a home equity loan or HELOC and change your mind? Federal law gives you an out. Under the Truth in Lending Act, you can cancel any credit transaction secured by your primary residence until midnight of the third business day after closing.7Office of the Law Revision Counsel. 15 USC 1635 – Right of Rescission as to Certain Transactions Send written notice to the lender. The lender must return any money or property you provided and release the lien within 20 days.
This is why lenders can’t hand you the money the same day you sign on a home-secured loan; they have to wait for the rescission window to close.8eCFR. 12 CFR 1026.15 – Right of Rescission If the lender fails to provide proper disclosures at closing, the window extends to three years. The right does not apply to personal loans, since they aren’t secured by your home, and it doesn’t apply to purchase-money mortgages.
What the Loan Doesn’t Cover: Taxes, Permits, Liens, Insurance
Interest Deduction
Interest on a home equity loan or HELOC used to build a garage is tax-deductible, since the IRS treats garage construction as a substantial improvement. The borrowed funds have to actually go into buying, building, or substantially improving the home that secures the loan. If you spend part of the loan on the garage and part on a vacation, only the garage portion qualifies. The deduction applies to mortgage debt up to $750,000, or $375,000 if married filing separately, for loans taken after December 15, 2017.9Internal Revenue Service. Publication 936, Home Mortgage Interest Deduction Interest on a personal loan used for the same project is not deductible, regardless of how the money is spent.
Property Tax Increase
A permanent structure will almost certainly raise your property tax bill. County assessors routinely review building permits to find new construction, and a garage adds square footage and functionality that increase assessed value. The size of the bump depends on your local rate, the assessed value of the improvement, and your jurisdiction’s reassessment schedule. Factor it into your budget alongside the loan payment.
Building Permits
Every jurisdiction requires a building permit for a garage. Starting work without one can bring fines, a stop-work order, or an order to tear the structure down. Fees vary by location and are often calculated as a percentage of project value. The permit also triggers inspections at foundation, framing, electrical, and final stages. Your contractor should handle the application, but you’re the one on the hook if the work isn’t permitted or inspected. Unpermitted structures also cause problems at sale, when the buyer’s lender and title company will flag them.
Mechanic’s Liens
Here’s a risk most homeowners overlook. If your general contractor doesn’t pay a subcontractor or supplier, that unpaid party can file a lien against your property in most states, even if you paid your contractor in full. The lien attaches to your title and has to be cleared before you can sell or refinance. Request lien waivers from your contractor and major subcontractors as each payment is made. A conditional lien waiver takes effect once the check clears and prevents future claims for work already paid for. Some construction lenders require lien waivers before releasing each draw, which works in your favor.
Insurance
A detached garage is covered under homeowners insurance as an “other structure” (Coverage B), typically set at 10% of your dwelling coverage. On a $400,000 dwelling limit, that’s $40,000 of other structures coverage by default. Enough for a basic build, maybe not if yours costs more or will hold valuable equipment. Call your insurer before construction and raise the limit if needed. An attached garage generally falls under main dwelling coverage (Coverage A), but tell the insurer about the addition so the policy reflects the higher value. Ask about builder’s risk coverage or an endorsement to protect the partially built structure from storms, theft, and vandalism during the project.
