Local Intelligence
What Schertz Homeowners Need to Know Before Submitting
Size & Zoning Rules
0Schertz does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
If the addition creates a second unit or is later converted to a rental, Schertz's ADU market supports approximately $1,353/month for a 2-bedroom unit.
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.
Addition permit packages 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 drawings are always required for any load-bearing elements, second-story work, or new foundation.
Visit Planning and Community Development Department ↗⚠ 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."

Common Questions
Schertz Home Addition FAQs
Do I need a permit for a home addition in Schertz? +
Yes — any structural addition to your home in Schertz requires a building permit. This applies to room additions, second-story additions, sunrooms, and attached garages. You'll need permit-ready drawings before the building department will accept your application. Our packages are formatted specifically for Schertz's submittal requirements.
How much does a home addition cost in Schertz? +
Home additions in Schertz typically cost between $150–$300 per square foot depending on the scope, finishes, and structural complexity. A 600 sq ft addition ranges from $90,000 to $180,000. Second-story additions cost more than ground-floor extensions due to structural requirements. Contact us to discuss drawing package options for your project.
What drawings are required to permit a home addition in Schertz? +
Schertz's building department requires: a site plan showing the addition's footprint and setbacks, floor plans for all affected levels, all four exterior elevations, an electrical plan, and energy compliance (Title 24 in California). Structural plans stamped by a licensed engineer are required for any load-bearing elements — included in our Premium package.
How long does the permit process take for a home addition in Schertz? +
Plan check in Schertz typically takes 8 weeks for home additions. Additions with structural components may require additional review. Complete, code-compliant drawings significantly reduce correction cycles — each cycle adds 3–6 weeks. Our drawings are engineered to pass on the first submittal.
What setbacks apply to home additions in Schertz? +
Schertz enforces minimum setbacks from property lines for all additions: typically 4–5 ft side setbacks and 5 ft rear setbacks, though these vary by zoning district and lot size. Your addition must stay within the buildable envelope. Our site plan documents existing and proposed setbacks and flags any zoning variances required.
Do I need structural drawings for a home addition in Schertz? +
Yes, for most additions. Any load-bearing walls, new foundations, second-story construction, or roof structure changes require stamped structural drawings from a licensed engineer. California's CBC (California Building Code) and seismic requirements make structural plans mandatory for most addition types. Our Standard and Premium packages include stamped structural drawings.
How much do home addition drawings cost in Schertz? +
Our permit-ready home addition drawing packages for Schertz include everything your building department requires — floor plans, elevations, structural, and energy compliance. Every package is engineered for TX code compliance and formatted for Schertz's building department. 14-day money-back guarantee.
Will a home addition increase my home's value in Schertz? +
In Schertz, where median home values are approximately $330,000, a permitted home addition adds square footage that appraisers value as part of the home's gross living area. Return on investment varies by addition type — master suite additions, family room expansions, and additional bedrooms typically recoup 50–75% of project cost in appraised value in TX markets.
Can I add a second story to my home in Schertz? +
Second-story additions are permitted in most Schertz residential zones, subject to height limits and design review requirements. California generally requires ministerial permit approval, but some cities impose design compatibility or neighborhood compatibility review for second stories. Our drawings cover all levels including foundation upgrades, shear walls, and roof framing required for vertical additions.
