What Schertz Homeowners Need to Know Before Submitting

Size & Zoning Rules

0

Schertz does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.

A fully permitted, code-compliant garage conversion in Schertz can command approximately $1,078/month as a 1-bedroom rental — far more than leaving the space as storage.

Permit Process & Fees

Planning and Community Development Department permit fees for this project type typically range from $850 to $1,225 depending on project valuation and scope.

Garage conversion drawings submitted to Planning and Community Development Department must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus stamped structural plans are typically required for converted garages that are detached or require seismic upgrades.

⚠ Common Pitfall in Schertz

A lot of Schertz lots sit on Guadalupe County's older septic systems rather than city sewer, and the county health department has to sign off separately before the city will even issue your ADU permit — that approval alone can take several weeks and may force a costly septic redesign if your existing system wasn't sized for a second dwelling. On top of that, Schertz's plan review only guarantees a 14-business-day turnaround for the first cycle, but if the reviewer kicks back comments (common for detached units with separate electrical service), each additional round adds another 7 business days, so homeowners often underestimate total time to permit issuance. Since STRs are allowed here, it's also worth checking your specific subdivision's deed restrictions, since several Schertz HOAs have added their own short-term rental bans that override the city's more permissive stance.

Expert Verdict — Marcus Reid, Licensed Designer

"In my experience, the missing timeline and cost-per-sqft figures here are a red flag rather than good news — this looks like a state-level placeholder, so I'd call Schertz's Planning and Community Development Department directly and get two or three local contractor quotes before budgeting anything. With HOA coverage near 48% and STRs technically allowed, I've seen plenty of Schertz deals stall not on city permitting but on an HOA restriction nobody checked until the plans were already drawn."

Schertz Garage Conversion FAQs

Is a garage conversion allowed in Schertz? +

Yes — garage conversions are permitted in Schertz. Texas's local zoning ordinances allow homeowners to convert an attached or detached garage into habitable living space or an ADU. A building permit and permit-ready drawings are required before work begins.

How much does a garage conversion cost in Schertz? +

Garage conversions in Schertz typically range from $75,000 to $165,000 depending on the existing structure, finish level, and scope of work. This is significantly less than building a new detached ADU. Contact us to discuss drawing package options for your project.

What drawings are required to permit a garage conversion in Schertz? +

Schertz's building department requires: a site plan showing the converted garage's location on the lot, floor plans with dimensions and room labels, all four exterior elevations, an electrical plan, and energy compliance documentation (the locally adopted energy code). Our Starter package covers all of these. If the garage is detached or the structure requires seismic upgrades, stamped structural drawings are also required — included in our Premium package.

How long does the permit process take for a garage conversion in Schertz? +

Plan check in Schertz typically takes approximately 6 weeks. Having complete, code-compliant drawings dramatically reduces correction cycles — which each add 3–6 weeks. Our drawings are designed to pass on the first submittal.

Can I convert my garage into a rental unit in Schertz? +

Yes — a permitted garage conversion can function as a standalone rental unit (an ADU, or a similar accessory-unit category depending on Texas's and Schertz's local rules). It can be rented long-term. Short-term rental rules vary by city — confirm with Schertz's planning department.

Do I need to replace the garage door opening when converting? +

Yes. The garage door must be replaced with an insulated wall with a standard entry door and at least one egress window (minimum 5.7 sq ft clear opening). This is captured in our elevation drawings and flagged in the electrical plan. The new wall must also meet TX energy code requirements, which we handle in the local energy code compliance documentation.

How much does it cost to get garage conversion drawings in Schertz? +

Our permit-ready garage conversion drawing packages for Schertz include floor plans, elevations, electrical, and energy compliance — everything your building department needs. Every package is engineered for TX code compliance and formatted for Schertz's building department. 14-day money-back guarantee.

Will converting my garage increase my home's value in Schertz? +

A permitted garage conversion in Schertz adds rentable square footage to a home currently valued around $330,000. Converted spaces typically appraise as habitable square footage, increasing the home's value. As an ADU or JADU, the rental income stream is also capitalized into the appraised value — typically at a 5–6% cap rate.
