Local Intelligence
What Golden Homeowners Need to Know Before Submitting
Size & Zoning Rules
Converting your garage to a legal rental unit means the finished space must comply with Golden's ADU size limits. Golden's current ADU size cap is 800 sq ft — within the typical range for most floor plan configurations.
Golden currently requires owner-occupancy on the primary parcel — meaning one of the units (the main home or the ADU/conversion) must be your primary residence.
A fully permitted, code-compliant garage conversion in Golden can command approximately $1,799/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
City of Golden Building Department permit fees for this project type typically range from $3,400 to $8,300 depending on project valuation and scope. Plan check runs approximately 18 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 Golden Building 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 City of Golden Building Department ↗Construction Cost Context
Golden's garage conversion construction costs run $320–$480 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 Golden
Many Golden lots near the foothills fall into the city's Hillside Overlay District, which triggers extra review for slope and drainage even if your ADU sits on a seemingly flat pad — inspectors care about the grade across the whole parcel, not just the building footprint. Because Golden requires a separate tap fee analysis through its own water utility (not Denver Water or a Jeffco special district), homeowners are often surprised to learn their existing 3/4-inch service line needs upsizing to handle a second unit, adding a few thousand dollars and a utility department sign-off before the building permit can even be routed for plan review. On top of that, Golden's 65% plan review surcharge on the base permit fee means your actual out-of-pocket cost at submittal is significantly higher than the fee schedule's headline number suggests.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Golden permitting, that 18-week timeline and the per-square-foot cost figure both read as state-level estimates rather than Golden-specific numbers, so I'd call the City of Golden Building Department directly and get a couple of local contractor quotes before penciling in a budget or start date; also worth noting, with 61% of the area under HOA governance, your actual timeline can hinge as much on HOA architectural review as it does on the city's plan check queue."

Common Questions
Golden Garage Conversion FAQs
Is a garage conversion allowed in Golden? +
Yes — garage conversions are permitted in Golden. 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 Golden? +
Garage conversions in Golden 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 Golden? +
Golden'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 Golden? +
Plan check in Golden typically takes approximately 18 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 Golden? +
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 Golden's local rules). It can be rented long-term. Short-term rental rules vary by city — confirm with Golden'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 Golden? +
Our permit-ready garage conversion drawing packages for Golden include floor plans, elevations, electrical, and energy compliance — everything your building department needs. Every package is engineered for CO code compliance and formatted for Golden's building department. 14-day money-back guarantee.
Will converting my garage increase my home's value in Golden? +
A permitted garage conversion in Golden adds rentable square footage to a home currently valued around $750,000. 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.
