Want to Build a Backyard Rental?
Charlotte homeowners have just gained a powerful new tool to create extra income while also providing affordable housing. Through the Queen City ADU Program, the City of Charlotte is now offering up to $80,000 in forgivable, interest-free financing to help residents build accessory dwelling units (ADUs).
An ADU is a secondary unit, like a backyard cottage or basement suite, with its own amenities. It’s a smart way to turn unused space into rental housing. The city’s new program lowers costs, permitting, and tenant processes.
A Forgivable Loan With a Purpose
The Queen City ADU Program is designed to encourage more affordable housing options across Charlotte. It gives homeowners access to 0% interest financing up to $80,000, covering as much as half of the total project costs. The other 50% comes from the homeowner through savings, loans, or equity.
The loan is forgivable, meaning it doesn’t have to be repaid if you follow the program rules. Each year you rent the ADU to an income-qualified tenant (earning 80% or less of the Area Median Income, or AMI), a portion, typically $10,000 per year, is forgiven. After eight years of compliance, the loan is completely erased.
Homeowners willing to lease through certain referral partners or voucher programs can accelerate forgiveness to $15,000 per year, completing the term in just over five years.
This setup aligns incentives, such as the city adding long-term affordable units, and property owners offsetting construction costs through a mix of free financing and steady rental income.
Who Can Apply and What’s Required
Both owner-occupants and non-occupant owners may apply, as long as the property sits within Charlotte city limits. If you’ve never managed a rental before and plan to lease to a non-relative, the city requires that you hire a professional property manager for the first 18 months. (That’s where an experienced management company like Henderson Properties comes in. We’ll handle compliance, leasing, and maintenance while you learn the ropes.)
Tenants must meet income thresholds, and rent must be within city limits, usually at 70% AMI for a studio. The lease must last at least a year, with annual recertification to prove compliance.
The program even streamlines the design phase. Participants get free access to city-approved, permit-ready ADU plans each compliant with Charlotte’s Unified Development Ordinance (UDO) and milestone-based construction payouts that go directly to your builder.
Size, Design, and Zoning
Charlotte’s UDO zoning overhaul allows one ADU per lot. Detached units can’t be over 1,000 sq ft or 50% of the main home’s size, whichever is smaller. The unit must stay under the same ownership, and utilities usually connect to existing lines.
If you live in a neighborhood with a homeowners’ association, review your covenants before applying, as some HOAs enforce their own restrictions. Otherwise, as long as your design complies with the city’s setback, height, and lot coverage limits, you’re probably fine.
Step-by-Step Gameplan
Even with city guidance, building an ADU can feel like a maze. Here’s how to handle the process smoothly:
1. Test your lot’s eligibility. Start with the City’s online ADU mapping tool. It instantly confirms whether your property qualifies and highlights any zoning quirks.
2. Set a clear budget and purpose. Decide whether your ADU will serve as rental income, family housing, or both. The city’s $80,000 match means your total budget should be at least $160,000, but smaller projects can still qualify proportionally.
3. Choose a design. Pick from the City’s free ADU plan library or hire a design-build team for a custom approach. Prefabricated and modular options can also fit within the program if they meet the relevant building codes.
4. Confirm utilities early. Consult with your plumber and electrician to determine whether separate meters or shared lines are more cost-effective; these details significantly impact costs and permitting time.
5. Secure an official address. The County assigns a unique address to every ADU. You’ll need it before pulling permits.
6. Apply for zoning approval. Charlotte’s Land Development (LDIRL) permit ensures your design complies with tree, stormwater, and setback rules.
7. Obtain your building permit. Once zoning is approved, Mecklenburg County Code Enforcement reviews structural and trade plans.
8. Build and inspect. Construction typically takes three to six months. City inspectors sign off at key stages, from framing to final walk-through.
9. Get your Certificate of Occupancy. This official approval allows you to move in a tenant.
10. Lease and report annually. Keep your unit rented to income-eligible tenants, file compliance paperwork, and watch the loan balance shrink every year.
Why It Matters for Homeowners and Investors
For homeowners, the math is compelling. With $80,000 of interest-free, forgivable funds, your out-of-pocket investment may drop by half, yet you’ll own a new income-producing asset that could generate $1,000–$1,200 per month in rent under current affordable limits. That’s a serious offset to your mortgage or a long-term boost to property value.
For investors, the program offers an intriguing middle ground between altruism and ROI. While rent caps prevent maximizing cash flow, free capital dramatically improves project returns. Add in Charlotte’s statewide legalization of ADUs through Senate Bill 495, and the opportunity broadens beyond this single program. ADUs are now permitted on nearly every single-family lot in North Carolina.
Annual recertification requires paperwork, income verification, lease copies, and rent receipts. Failure to comply could trigger repayment of unforgiven funds. But with professional property management, it’s easy to stay on track. Henderson Properties already manages long-term rentals citywide and can ensure your ADU remains compliant, occupied, and profitable.
