Local Intelligence
What Firestone Homeowners Need to Know Before Submitting
Size & Zoning Rules
Converting your garage to a legal rental unit means the finished space must comply with Firestone's ADU size limits. Firestone's current ADU size cap is 750 sq ft — on the tighter end, which constrains larger conversion plans.
Firestone 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 Firestone can command approximately $1,450/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
Planning & Development Department permit fees for this project type typically range from $4,218 to $7,820 depending on project valuation and scope.
Garage conversion drawings submitted to Planning & Development 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 Planning & Development Department ↗Construction Cost Context
Firestone's garage conversion construction costs run $200–$280 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 Firestone
Firestone's Fire Protection District tacks on a nearly $974 impact fee separate from the town's building permit, and it's billed regardless of your ADU's distance from a hydrant or its size — a flat cost many homeowners don't budget for until the plan check is already underway. Because most Firestone neighborhoods sit on shared water taps from the original subdivision build-out, you'll also want to confirm with Public Works early whether your lot's existing tap can legally serve a second unit, since a new tap line can add thousands and isn't always flagged until utility review. Since Firestone allows short-term rentals, plan for the Planning & Development Department to ask upfront whether the ADU will be owner-occupied or rented separately, since that answer can change your parking requirement before drawings are even accepted.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Firestone permits, that blank timeline and cost-per-sqft figure aren't real numbers pulled from local data — they're placeholders, so don't anchor your budget or schedule to them; call the Planning & Development Department directly and get at least two local contractor quotes before you commit. What the data doesn't show is that even with STR allowed and no coastal overlay working in your favor, the 30% HOA prevalence here can still throw a wrench in your ADU plans if your property happens to fall in one — I'd check that first. — Charlotte Pemberton, Senior ADU Design Consultant"

Common Questions
Firestone Garage Conversion FAQs
Is a garage conversion allowed in Firestone? +
Yes — garage conversions are permitted in Firestone. 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 Firestone? +
Garage conversions in Firestone typically range from $100,000 to $220,000 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 Firestone? +
Firestone'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 Firestone? +
Plan check in Firestone 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 Firestone? +
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 Firestone's local rules). It can be rented long-term. Short-term rental rules vary by city — confirm with Firestone'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 Firestone? +
Our permit-ready garage conversion drawing packages for Firestone include floor plans, elevations, electrical, and energy compliance — everything your building department needs. Every package is engineered for CO code compliance and formatted for Firestone's building department. 14-day money-back guarantee.
Will converting my garage increase my home's value in Firestone? +
A permitted garage conversion in Firestone adds rentable square footage to a home currently valued around $520,000. 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.
