Quick Answers About Nacogdoches, TX ADUs
Market Context
Nacogdoches has a median home value of $200,000. Adding an ADU typically increases that by 22% — approximately $44,000 in added equity. A 1-bedroom ADU in Nacogdoches rents for approximately $823/month in the Nacogdoches County rental market , yielding a 6.5% cap rate on the investment. Occupancy averages 95% in this market.
Top Nacogdoches neighborhoods for ADU investment include Near Stephen F. Austin State University (SFA), Downtown Nacogdoches (Historic District / Pecan Park area), Northeast Nacogdoches, East Side (Chevy Chase / Mize St area near SFA), North & South of Downtown (University Drive corridor). Highest rental demand in the city from 11,000+ SFA students plus faculty and staff, with chronically tight housing supply making detached ADUs highly marketable. Walkable to downtown jobs, restaurants, and SFA; character-filled homes on modest lots where owners can convert outbuildings or build small detached units for premium short-term and faculty rentals.
Permit Process
Permit applications are reviewed by the Office of Development . Design review: Yes - in historic districts only
Because Nacogdoches still runs on the old Standard Building Code rather than the current International Residential Code many other Texas cities use, the Office of Development calculates your permit fee off a fee table (Appendix B) that isn't posted online — meaning you often can't get a real fee quote until you physically bring plans into their office. Many older lots in town, especially near downtown and around Stephen F. Austin State University, are still on shared or undersized sewer taps from decades ago, so adding an ADU can trigger a requirement to upsize your sewer line at your own cost before the city will sign off. Since short-term rentals aren't allowed here, be ready to prove intended use — the city has asked owners for a signed affidavit or lease stating the unit is for long-term family or tenant housing, not an Airbnb.
"In my experience, both that permit timeline and the per-square-foot cost you're seeing here are really state-level averages, not Nacogdoches-specific numbers — I'd call our Office of Development and get two or three local contractor quotes before penciling in a budget or a move-in date. What the data also doesn't show is how much a rough drawing set can slow things down here, so don't be surprised if it takes noticeably longer than whatever baseline figure is listed."
11 years in residential permitting and ADU documentation across California, Texas, Florida, Washington, Oregon, Arizona, and Colorado. This guide was researched and verified against Nacogdoches's building department records and current 2026 Texas's local zoning ordinances.
Property Eligibility
Is My Nacogdoches, TX Property Eligible for an ADU?
Nacogdoches 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 Nacogdoches under Texas's local zoning ordinances — Texas has no statewide ADU-approval law. No owner-occupancy requirement in Nacogdoches — you can rent both units as investment properties. Review process and timelines are set entirely by local ordinance — confirm the current process with the Office of Development 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 Nacogdoches's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 20% of Nacogdoches 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.

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 × 22% 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 Nacogdoches ADU Rules
Nacogdoches's 2026 ADU ordinance caps new units at 1,200 sq ft and 35 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. Nacogdoches 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 vary by project valuation — in line with what most homeowners budget for permitting through Office of Development. Submit directly to the department online — link below.
| Regulation | Nacogdoches Allowance |
|---|---|
| Max ADU Size | Set by local ordinance (no TX state cap) |
| Max Height | 35 ft |
| Side Setback | 5 ft |
| Rear Setback | 10 ft |
| Architect / Engineer Stamp | Not required under the size cap* |
| Owner Occupancy | Not required |

| Coastal Overlay | No |
| Design Review | Yes - in historic districts only |
| HOA Prevalence | 20% of properties |

*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 Office of Development before designing.
