Local Intelligence
What Montrose Homeowners Need to Know Before Submitting
Size & Zoning Rules
Converting your garage to a legal rental unit means the finished space must comply with Montrose's ADU size limits. Montrose's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Montrose 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 Montrose can command approximately $1,327/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
Garage conversion drawings submitted to Building Services 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 Building Services ↗Construction Cost Context
Montrose's garage conversion construction costs run $322–$450 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 Montrose
Even though Montrose rolled out its Pre-Approved ADU Program in August 2025 to speed things up, that shortcut only applies if your plans match one of the pre-vetted designs exactly — any tweak to the footprint or roofline kicks you back into standard review with Building Services, which can quietly erase the time savings you were counting on. Homeowners also get tripped up by the city's separate water tap fee schedule, since adding a second dwelling unit usually triggers a new tap fee calculation rather than letting you piggyback on the existing house's connection. And because short-term rentals aren't allowed on ADUs here, anyone pitching the unit as an Airbnb income source in their financing plan needs to rework those numbers before they even talk to the bank.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, when the timeline and cost fields come back blank like this, it usually means Montrose doesn't have reliable local data plugged in yet, so treat any state-level averages you find elsewhere with real caution — call Montrose Building Services directly for a current plan check queue estimate and get two or three local contractor quotes before you budget per square foot. I'd also note that with 25% HOA prevalence in the area, that's one more approval layer many homeowners forget to factor into their timeline."

Common Questions
Montrose Garage Conversion FAQs
Is a garage conversion allowed in Montrose? +
Yes — garage conversions are permitted in Montrose. Colorado 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 Montrose? +
Garage conversions in Montrose typically range from $80,000 to $176,000 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 Montrose? +
Montrose'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 2021 IECC (Colorado's statewide-mandated minimum)). 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 Montrose? +
Plan check in Montrose 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 Montrose? +
Yes — a permitted garage conversion can function as a standalone rental unit (an ADU, or a similar accessory-unit category depending on Colorado's and Montrose's local rules). It can be rented long-term. Short-term rental rules vary by city — confirm with Montrose'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 CO energy code requirements, which we handle in the CO energy code compliance documentation.
How much does it cost to get garage conversion drawings in Montrose? +
Our permit-ready garage conversion drawing packages for Montrose include floor plans, elevations, electrical, and energy compliance — everything your building department needs. Every package is engineered for CO code compliance and formatted for Montrose's building department. 14-day money-back guarantee.
Will converting my garage increase my home's value in Montrose? +
A permitted garage conversion in Montrose adds rentable square footage to a home currently valued around $400,000. 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.
