Local Intelligence
What Irving Homeowners Need to Know Before Submitting
Size & Zoning Rules
0Irving currently requires owner-occupancy on the primary parcel — meaning one of the units (the main home or the ADU/conversion) must be your primary residence.
A fully permitted, code-compliant garage conversion in Irving can command approximately $1,258/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
Irving Inspections Department permit fees for this project type typically range from $2,000 to $8,000 depending on project valuation and scope. Plan check runs approximately 6 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Garage conversion drawings submitted to Irving Inspections 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.
Visit Irving Inspections Department ↗Construction Cost Context
Irving's garage conversion construction costs run $210–$294 per square foot — a moderate range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.
⚠ Common Pitfall in Irving
Irving's zoning ordinance requires a separate accessory structure setback survey before the Inspections Department will even log your ADU application, and many older lots in neighborhoods like Plymouth Park or Cottonwood Valley have platted easements that eat into your buildable area more than county records show. Because Irving ties ADU electrical permits to Oncor's service capacity check, homeowners on older 100-amp panels often get stuck waiting 3-4 extra weeks for a panel upgrade approval before framing inspections can even be scheduled. And since short-term rentals aren't allowed here, expect the plan reviewer to specifically flag any second kitchen setup that looks rental-ready, which can trigger a use clarification request that adds another review cycle.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Irving permitting, that 6-week timeline is best-case for a clean, correction-free submittal—I routinely see it stretch to 10-12 weeks once plan check comments come back on a first-time drawing set. The $300/sqft figure also reads like a statewide estimate rather than a true local number, so I'd get at least two local contractor bids and call the Irving Inspections Department directly before you lock in a budget."
Market Context
Irving has a median home value of $265,000. Comparable renovation projects in this market typically add 22.0% to resale value.
Neighborhoods in Irving with the strongest garage conversion and rental-unit potential include Las Colinas, Valley Ranch, Urban Center (Las Colinas), Broadmoor Hills, Cardinal Family Village. High job density and strong rental demand near Las Colinas offices and DFW make ADUs lucrative.
Permit Process

Permit fees in Irving range from $2,000 to $8,000 depending on project scope. Design review: Yes - in certain cases: ADUs/guest quarters require S-P-1 site-plan (zoning) approval and are subject to overlay/historic-district review where applicable.

Common Questions
Irving Garage Conversion FAQs
Is a garage conversion allowed in Irving? +
Yes — garage conversions are permitted in Irving. Texas state law allows 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 Irving? +
Garage conversions in Irving typically range from $35,000 to $77,000 depending on the existing structure, finish level, and scope of work. This is significantly less than building a new detached ADU. Our drawing package starts at $997 — a fraction of what a local architect would charge for the same permit-ready set.
What drawings are required to permit a garage conversion in Irving? +
Irving'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 (Title 24 in California). 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 Irving? +
Plan check in Irving 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 Irving? +
Yes — a permitted garage conversion can function as a standalone rental unit (ADU or JADU depending on size). In California, converted garages under 500 sq ft qualify as Junior ADUs (JADUs), while larger conversions qualify as full ADUs. Both can be rented long-term. Short-term rental rules vary by city — confirm with Irving'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 Title 24 compliance documentation.
How much does it cost to get garage conversion drawings in Irving? +
Our permit-ready garage conversion drawing packages for Irving start at $997. Local architects typically charge $2,500–$6,000 for the same set. Every package is engineered for TX code compliance and formatted for Irving's building department. Turnaround is 10 business days with a 14-day money-back guarantee.
Will converting my garage increase my home's value in Irving? +
A permitted garage conversion in Irving adds rentable square footage to a home currently valued around $265,000. 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.
