Local Intelligence
What Sandy Homeowners Need to Know Before Submitting
Size & Zoning Rules
Converting your garage to a legal rental unit means the finished space must comply with Sandy's ADU size limits. Sandy's current ADU size cap is 720 sq ft — on the tighter end, which constrains larger conversion plans.
Sandy 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 Sandy can command approximately $1,623/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
City of Sandy Building Division permit fees for this project type typically range from $51,000 to $53,000 depending on project valuation and scope. Plan check runs approximately 5.5 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Garage conversion drawings submitted to City of Sandy Building Division 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 City of Sandy Building Division ↗Construction Cost Context
Sandy's garage conversion construction costs run $245–$412 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 Sandy
Sandy's Master Fee Schedule technically charges full System Development Charges (water, sewer, parks, streets) that can add up to roughly $47,000 on top of your base permit costs — but Oregon's HB 2007 and SB 8 require the city to waive or cap these for most ADUs, so you need to specifically request that reduction rather than pay whatever the counter clerk first quotes you. Because Sandy sits in Seismic Zone D, plan reviewers also scrutinize foundation and shear wall details more closely than you'd see in a Portland suburb with a lower seismic rating, which is a common reason first-round plans get kicked back during the 5-6 week review. If your lot is on one of Sandy's older streets with a shared or undersized water line, Public Works may also require a separate street approach and service upgrade inspection before they'll sign off on final utility connection.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience working with Sandy homeowners, that 5.5-week timeline and the per-square-foot cost figure are both state-level estimates rather than verified local numbers, so I'd treat them as a starting point and call the City of Sandy Building Division and a couple of local contractors before penciling in a budget or schedule. I've also seen even straightforward submittals stretch past 5.5 weeks once you factor in a first round of plan check corrections, so build in a cushion."

Common Questions
Sandy Garage Conversion FAQs
Is a garage conversion allowed in Sandy? +
Yes — garage conversions are permitted in Sandy. Oregon 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 Sandy? +
Garage conversions in Sandy typically range from $115,000 to $253,000 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 Sandy? +
Sandy'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 Oregon Residential Energy Efficiency Specialty 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 Sandy? +
Plan check in Sandy typically takes approximately 5.5 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 Sandy? +
Yes — a permitted garage conversion can function as a standalone rental unit (an ADU, or a similar accessory-unit category depending on Oregon's and Sandy's local rules). It can be rented long-term. Short-term rental rules vary by city — confirm with Sandy'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 OR energy code requirements, which we handle in the OR energy code compliance documentation.
How much does it cost to get garage conversion drawings in Sandy? +
Our permit-ready garage conversion drawing packages for Sandy include floor plans, elevations, electrical, and energy compliance — everything your building department needs. Every package is engineered for OR code compliance and formatted for Sandy's building department. 14-day money-back guarantee.
Will converting my garage increase my home's value in Sandy? +
A permitted garage conversion in Sandy adds rentable square footage to a home currently valued around $500,000. 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.
