⚠️
Heads Up — Local Complexity in Nacogdoches

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.

Charlotte Pemberton
Expert's Note — Charlotte Pemberton, Senior ADU Consultant
"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."

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.

🏛️

Historic Districts

Yes - in historic districts only

Always verify eligibility with Office of Development before designing.

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

Owner Occupancy Not required

*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.

Construction costs in Nacogdoches typically range from $200–$400 per square foot depending on project complexity, finishes, and site conditions.
What is the maximum ADU size allowed in Nacogdoches? +
Texas has no statewide ADU size law. Nacogdoches's local zoning ordinance sets the applicable cap — contact the building department to confirm current rules before designing.
How long does the ADU permit process take in Nacogdoches? +
ADU permit timelines in Texas vary by city since there's no statewide ADU law — plan check commonly runs 4–10 weeks depending on the jurisdiction. Our permit-ready drawings are designed to pass on the first submittal, saving weeks of back-and-forth.
Do I need owner-occupancy to build an ADU in Nacogdoches? +
No — Nacogdoches does not require owner-occupancy for ADUs. You can rent both the main house and the ADU as investment properties.
What's the rental income potential for an ADU in Nacogdoches? +
In Nacogdoches, a 1-bedroom ADU rents for approximately $823/month. Studios average $375 and 2-bedroom units bring $1,147. With an occupancy rate of 95%, annual gross rent on a 1BR ADU would be approximately $9,382.
How much does it cost to get ADU drawings in Nacogdoches? +
Our permit-ready ADU drawing packages for Nacogdoches cover everything TX's building department requires — engineered to pass plan check on the first submittal. Contact us for current package details and pricing. 14-day money-back guarantee.
What drawings are required for an ADU permit in Nacogdoches? +
Nacogdoches's building department requires: a site plan, floor plans, elevations (all four sides), an electrical plan, and energy compliance documentation (local energy code). Our Standard package includes all of these. The Premium package adds structural plans with engineer stamp — required for detached ADUs in most Texas cities. All drawings are TX-code compliant and formatted for local submission.
Can I convert my garage to an ADU in Nacogdoches? +
Yes. Garage conversions are one of the most cost-effective ADU options in Nacogdoches. Conversion costs start around $115,000 — significantly less than new construction. The existing footprint counts toward ADU square footage limits. Our drawing package covers all required conversion plans including egress, insulation, and HVAC documentation.
What neighborhoods in Nacogdoches are best for ADU investment? +
Near Stephen F. Austin State University (SFA), Downtown Nacogdoches (Historic District / Pecan Park area), Northeast Nacogdoches. 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.
Is Nacogdoches ADU-friendly? +
Nacogdoches is governed by Texas's local zoning ordinances — Texas has no statewide ADU-approval law. Review process and timelines are set entirely by local ordinance — confirm the current process with the Office of Development before designing.
How much will an ADU increase my property value in Nacogdoches? +
ADUs in Nacogdoches typically increase property values by 22%. On a $200,000 home, that's an estimated $44,000 in added value. Cap rates average 6.5% in Nacogdoches.
Can I use my Nacogdoches ADU as a short-term rental (Airbnb / VRBO)? +
Nacogdoches restricts short-term rentals (under 30 days) in ADUs. The unit can be rented long-term — a 12-month lease is the most straightforward path. Texas has no statewide STR law, so Nacogdoches's local ordinance (and any HOA covenant) governs whether short-term rental is allowed.
Does Nacogdoches's seismic zone affect ADU construction requirements? +
Nacogdoches falls within Seismic Design Category A. This means ADU foundations, anchor bolts, shear walls, and hold-downs must meet the wind-load and structural provisions of Nacogdoches's locally adopted building code — Texas has no statewide seismic code, but coastal counties carry separate windstorm certification requirements — required for detached ADUs and strongly recommended for garage conversions where the existing structure may not meet current seismic standards.
Where do I submit ADU plans in Nacogdoches? +
Office of Development handles ADU permit applications — online submission is available through the permit portal. Permit fees in Nacogdoches range from N/A to N/A depending on project scope and valuation. Our drawing sets are formatted specifically for Nacogdoches's submittal requirements to minimize plan check cycles.
