Quick Answers About Anna, TX ADUs
Market Context
Anna has a median home value of $380,000. Adding an ADU typically increases that by 25% — approximately $95,000 in added equity. A 1-bedroom ADU in Anna rents for approximately $1,281/month in the Collin County rental market , yielding a 3.5% cap rate on the investment. Occupancy averages 94% in this market.
Top Anna neighborhoods for ADU investment include Hurricane Creek, Waterstone Estates, Trinity Falls, Pecan Hollow, Anna Crossing. Custom-home subdivision featuring large lots near downtown Anna and a golf course; spacious yards readily accommodate detached ADUs for premium tenants and commuting professionals. Luxury estate neighborhood on 1+ acre tracts, providing the largest yards in Anna — ideal footprint for high-end detached ADUs catering to McKinney/Frisco executives along the US 75 corridor.
Permit Process
Permit applications are reviewed by the Building Department . Permit fees in Anna range from $3,285 to $3,285 depending on project scope. Design review: Yes - citywide
Anna treats a detached ADU as a full second single-family unit, not a simple accessory structure, which means you're paying the same flat $2,400 building permit fee as a brand-new house plus separate mechanical, electrical, and plumbing permits — that adds up fast on a small backyard unit. Because many Anna neighborhoods were built out by production homebuilders like Meritage and Lennar, your lot may still carry a builder-recorded deed restriction or HOA covenant limiting detached structures, even though the city itself doesn't require HOA sign-off for the permit. Also check your water meter size with the city's Public Works office early — several older sections of Anna were platted with meters too small to support a second unit, and upsizing means a separate tap fee and a wait on scheduling with the city crew, not just your contractor.
"In my experience with Anna permits, that missing timeline and blank cost-per-sqft figure aren't just data gaps—they signal you're looking at a Texas state-level placeholder rather than a true local number, so I'd call Anna's Building Department directly and get two or three local contractor quotes before penciling in a budget or start date. With HOA coverage sitting at 63% here, I'd also flag that STR approval at the city level means very little if your specific subdivision's HOA restricts short-term rentals, so check that governing document before counting on rental income."

Property Eligibility
Is My Anna, TX Property Eligible for an ADU?
Anna homeowners are governed by Texas's local zoning ordinances — Texas has no statewide ADU-approval law. Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in Anna under Texas's local zoning ordinances — Texas has no statewide ADU-approval law. Anna requires owner occupancy — the property owner must reside in the primary home or the ADU. Review process and timelines are set entirely by local ordinance — confirm the current process with the Building Department before designing.
Multi-Family Property
Additional ADUs on multi-family and duplex lots may qualify under Texas's local zoning ordinances — Texas has no statewide ADU-approval law — the exact number and type allowed depends on Anna's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 63% of Anna homes are in an HOA. Texas has no statute limiting HOA power over ADUs — HOAs can restrict or ban ADUs and short-term rentals through their covenants (Texas Property Code Ch. 202/204/209). Our drawings include HOA submission formatting.
Always verify eligibility with Building Department before designing.

Anna ADU Return Calculator — Built With 2026 Local Data
Pre-loaded with verified Anna construction costs, median rental rates, and property value uplift data. Adjust the inputs to model your specific project.
Your Project
Projected Returns
* Estimates only. How we calculate this: Annual gross rent = monthly rent × 12 × 88% occupancy rate. Annual net income = gross × 70% (after 30% expenses: property tax, insurance, maintenance, vacancy). Value added = median home value × 25% uplift (regional ADU comparables). Total return = net income × years + value added. Break-even = total build cost ÷ annual net income. Consult a licensed financial advisor before investing.

Local Zoning Rules
2026 Anna ADU Rules
Anna's 2026 ADU ordinance caps new units at 1,000 sq ft and 18 ft of height — in the typical range most ADU floor plans are designed around. Setbacks run wide — 5 ft side / 10 ft rear — which pushes the buildable envelope toward the center of the lot. Anna doesn't trigger the extra engineer-stamp requirement we see in higher seismic-risk or hurricane-code cities — a standard code-compliant ADU under the size cap can typically be designed and submitted without an architect or engineer stamp, though any load-bearing change to the existing house still needs one.
Permit fees run $3,285–$3,285 — in line with what most homeowners budget for permitting through Building Department. Submit directly to the department online — link below.
| Regulation | Anna Allowance |
|---|---|
| Max ADU Size | 1,000 sq ft |
| Max Height | 18 ft |
| Side Setback | 5 ft |
| Rear Setback | 10 ft |
| Architect / Engineer Stamp | Not required under the size cap* |
| Owner Occupancy | Required |
| Short-Term Rental | Permitted |
| Coastal Overlay | No |
| Design Review | Yes - citywide |
| HOA Prevalence | 63% of properties |
| Permit Fees | $3,285–$3,285 |
*Load-bearing modifications to the existing house always need an engineer stamp regardless of ADU size. Data verified 2026-08-15T06:10:50.038Z. Always confirm with the Building Department before designing.
