Quick Answers About Georgetown, TX ADUs
Market Context
Georgetown has a median home value of $380,000. Adding an ADU typically increases that by 30% — approximately $114,000 in added equity. A 1-bedroom ADU in Georgetown rents for approximately $1,286/month in the Williamson County rental market , yielding a 5.2% cap rate on the investment. Occupancy averages 92% in this market.
Top Georgetown neighborhoods for ADU investment include Old Town District, Wolf Ranch, University Park East, Georgetown Village, Berry Creek. High rental demand from downtown and nearby Southwestern University makes ADUs attractive. Large single-family subdivisions with steady renter interest and convenient access to retail and I‑35.
Permit Process
Permit applications are reviewed by the Development Services , with a plan check timeline of approximately 3.5 weeks. Permit fees in Georgetown range from $13,400 to $13,650 depending on project scope. Design review: Yes - Special Use Permit required in several residential districts; additional historic/Old Town overlay review applies
Many older neighborhoods inside Georgetown's historic districts (like sections near Old Town) require a Certificate of Appropriateness from the Historic and Architectural Review Commission before Development Services will even log your ADU application, adding weeks of extra review focused on roofline and exterior materials matching the main house. Since short-term rentals aren't allowed, the city will also ask you to sign an affidavit confirming intended long-term use, and Williamson County's separate septic or well permitting can trip up lots outside city water/sewer lines, especially in older annexed subdivisions. Plan for the plumbing inspector to require a dedicated cleanout tie-in inspection separate from the main house, which locals often forget to schedule until the final walkthrough gets delayed.
"In my experience, that 3.5-week timeline and $250/sqft figure are Georgetown state-level estimates, not local verified numbers—I've seen actual plan check queues run considerably longer, especially when the drawing set comes back with even minor correction comments, so I'd call Development Services directly and get a couple of local contractor quotes before penciling in a budget or start date. With HOA presence at 66% in this area, don't overlook that separate architectural review layer either—it often adds its own timeline on top of whatever the county quotes you."

Property Eligibility
Is My Georgetown, TX Property Eligible for an ADU?
Georgetown 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 Georgetown under Texas's local zoning ordinances — Texas has no statewide ADU-approval law. Georgetown 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 Development Services 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 Georgetown's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 66% of Georgetown 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.
Historic Districts
Yes - Special Use Permit required in several residential districts; additional historic/Old Town overlay review applies
Always verify eligibility with Development Services before designing.

Georgetown ADU Return Calculator — Built With 2026 Local Data
Pre-loaded with verified Georgetown 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 × 30% 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.

Georgetown ADU Market at a Glance
Local Zoning Rules
2026 Georgetown ADU Rules
Georgetown's 2026 ADU ordinance caps new units at 1,200 sq ft and 15 ft of height — in the typical range most ADU floor plans are designed around. Setbacks run 5 ft side and 3 ft rear, close to the regional baseline. Georgetown 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 $13,400–$13,650 — in line with what most homeowners budget for permitting, and plan check takes about 3.5 weeks at Development Services. Submit directly to the department online — link below.
| Regulation | Georgetown Allowance |
|---|---|
| Max ADU Size | Set by local ordinance (no TX state cap) |
| Max Height | 15 ft |
| Side Setback | 5 ft |
| Rear Setback | 3 ft |
| Architect / Engineer Stamp | Not required under the size cap* |
| Owner Occupancy | Required |
| Short-Term Rental | Restricted |
| Coastal Overlay | No |
| Design Review | Yes - Special Use Permit required in several residential districts; additional historic/Old Town overlay review applies |
| HOA Prevalence | 66% of properties |
| Permit Fees | $13,400–$13,650 |
*Load-bearing modifications to the existing house always need an engineer stamp regardless of ADU size. Data verified 2026-07-12T23:00:00.000Z. Always confirm with the Development Services before designing.
