Local Intelligence
What Lebanon Homeowners Need to Know Before Submitting
Size & Zoning Rules
Converting your garage to a legal rental unit means the finished space must comply with Lebanon's ADU size limits. Lebanon's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Lebanon 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 Lebanon can command approximately $1,299/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
Development Services Department permit fees for this project type typically range from $2,500 to $9,000 depending on project valuation and scope. Plan check runs approximately 7 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
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
Lebanon's garage conversion construction costs run $200–$375 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 Lebanon
Lebanon's Development Services Department will require your engineer to design the ADU foundation and shear walls to Seismic Design Category D1 standards, which often means added hold-downs and thicker footings that a standard prefab ADU plan won't already include — expect your structural engineer to redline the stock plans. Because many Lebanon lots still run on older sewer laterals installed before city standards tightened, Public Works frequently requires a sewer video inspection before they'll approve your connection, and if the line fails, you're looking at a trenching repair that can add several weeks and thousands of dollars before framing even starts. Since STRs are allowed, it's worth confirming with the city whether your specific lot has any deed restrictions from a prior subdivision approval, as a handful of Lebanon parcels carry HOA-style covenants limiting rentals that predate current city rules.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 7-week plan check and $250/sqft figure are Lebanon-wide estimates, not gospel — I'd get a couple of local contractor quotes and call the Development Services Department directly before penciling in a budget or start date. Even without a coastal overlay to slow things down, incomplete drawing sets are the real culprit I've seen push that 7-week window out considerably, so submit a tight, fully-dimensioned set the first time. — Charlotte Pemberton, Senior ADU Design Consultant"

Common Questions
Lebanon Garage Conversion FAQs
Is a garage conversion allowed in Lebanon? +
Yes — garage conversions are permitted in Lebanon. Oregon 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 Lebanon? +
Garage conversions in Lebanon typically range from $85,000 to $187,000 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 Lebanon? +
Lebanon'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 Lebanon? +
Plan check in Lebanon typically takes approximately 7 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 Lebanon? +
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 Lebanon'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 Title 24 compliance documentation.
How much does it cost to get garage conversion drawings in Lebanon? +
Our permit-ready garage conversion drawing packages for Lebanon start at $997. Local architects typically charge $2,500–$6,000 for the same set. Every package is engineered for OR code compliance and formatted for Lebanon'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 Lebanon? +
A permitted garage conversion in Lebanon adds rentable square footage to a home currently valued around $310,000. 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.
