Local Intelligence
What Arvada Homeowners Need to Know Before Submitting
Size & Zoning Rules
Converting your garage to a legal rental unit means the finished space must comply with Arvada's ADU size limits. Arvada's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Arvada 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 Arvada can command approximately $1,523/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
Building Services permit fees for this project type typically range from $4,359 to $5,078 depending on project valuation and scope. Plan check runs approximately 3 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
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
Arvada'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 Arvada
Arvada's Building Services often requires a separate tap fee study for water and sewer if your ADU adds a bedroom, since many older lots in the North Arvada and Olde Town areas are still on undersized service lines that can't legally support a second unit without upgrading the connection at the main. This tap upgrade alone can run several thousand dollars and isn't something the standard permit checklist flags upfront, so homeowners often get surprised mid-review. On top of that, Jefferson County's overlapping records for lot lines in some older subdivisions can cause setback disputes that stall plan review until a licensed surveyor confirms the actual boundary.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Arvada permitting, that 3-week timeline is best-case for a spotless drawing set — most first-time applicants see at least one correction cycle that pushes it closer to 6-8 weeks, so call Building Services directly to check current queue times before penciling in a start date. I'd also treat that $300/sqft figure as a state-level ballpark rather than gospel; with 34% of the area under HOAs adding their own design review layer, I always tell clients to get two or three local contractor quotes before budgeting."
Market Context

Common Questions
Arvada Garage Conversion FAQs
Is a garage conversion allowed in Arvada? +
Yes — garage conversions are permitted in Arvada. Colorado 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 Arvada? +
Garage conversions in Arvada typically range from $150,000 to $330,000 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 Arvada? +
Arvada'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 Arvada? +
Plan check in Arvada typically takes approximately 3 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 Arvada? +
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 Arvada'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 Title 24 compliance documentation.
How much does it cost to get garage conversion drawings in Arvada? +
Our permit-ready garage conversion drawing packages for Arvada start at $997. Local architects typically charge $2,500–$6,000 for the same set. Every package is engineered for CO code compliance and formatted for Arvada'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 Arvada? +
A permitted garage conversion in Arvada adds rentable square footage to a home currently valued around $521,000. 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.
