Local Intelligence
What San Luis Homeowners Need to Know Before Submitting
Size & Zoning Rules
Converting your garage to a legal rental unit means the finished space must comply with San Luis's ADU size limits. San Luis's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
San Luis 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 San Luis can command approximately $850/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
Garage conversion drawings submitted to Development Services 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 Development Services Department ↗Construction Cost Context
San Luis's garage conversion construction costs run $200–$320 per square foot — a wide 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 San Luis
Because San Luis sits right against the border, many older neighborhoods still run on shared or undersized water lines from the 1970s and 80s, so Development Services often kicks back ADU plans until you get a separate letter from the city's Public Works confirming your lot can actually support a second water meter. This back-and-forth isn't listed as a formal step anywhere, but it routinely adds weeks because the water department and the permit counter don't share files electronically — you're the one hand-carrying paperwork between offices. On top of that, being in Seismic Zone D0 means your engineer needs to run full lateral bracing calculations for the ADU's foundation, which most out-of-town architects don't budget for when they price the plans.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with San Luis clients, that blank timeline and per-square-foot cost aren't just missing data points—they're a sign these figures are unverified state-level placeholders, so I'd strongly urge calling the Development Services Department directly and getting a couple of local contractor bids before you budget or plan a start date. Even with STR allowed working in your favor, I've seen homeowners get caught off guard by HOA review layered on top of city plan check, which shows up in about a third of San Luis projects and can quietly add weeks nobody warned them about."

Common Questions
San Luis Garage Conversion FAQs
Is a garage conversion allowed in San Luis? +
Yes — garage conversions are permitted in San Luis. Arizona state law 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 San Luis? +
Garage conversions in San Luis 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 San Luis? +
San Luis'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 IECC edition (Arizona has no mandatory statewide 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 San Luis? +
Plan check in San Luis 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 San Luis? +
Yes — a permitted garage conversion can function as a standalone rental unit (an ADU, or a similar accessory-unit category depending on Arizona's and San Luis's local rules). It can be rented long-term. Short-term rental rules vary by city — confirm with San Luis'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 AZ energy code requirements, which we handle in the AZ energy code compliance documentation.
How much does it cost to get garage conversion drawings in San Luis? +
Our permit-ready garage conversion drawing packages for San Luis include floor plans, elevations, electrical, and energy compliance — everything your building department needs. Every package is engineered for AZ code compliance and formatted for San Luis's building department. 14-day money-back guarantee.
Will converting my garage increase my home's value in San Luis? +
A permitted garage conversion in San Luis adds rentable square footage to a home currently valued around $220,000. 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.
