Local Intelligence
What Brighton Homeowners Need to Know Before Submitting
Size & Zoning Rules
Converting your garage to a legal rental unit means the finished space must comply with Brighton's ADU size limits. Brighton's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Brighton 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 Brighton can command approximately $1,539/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
Community Development department permit fees for this project type typically range from $1,000 to $8,000 depending on project valuation and scope. Plan check runs approximately 6 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Garage conversion drawings submitted to Community 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 Community Development department ↗Construction Cost Context
Brighton's garage conversion construction costs run $210–$315 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 Brighton
Brighton's Community Development department requires proof of separate water tap fees for detached ADUs, and since many older lots in the city were platted before current Adams County water rights rules, homeowners often discover mid-permit that their lot only has one tap allocated — forcing a costly renegotiation with the South Adams County Water and Sanitation District before plans move forward. This tap issue rarely shows up until the plan review stage, so it blindsides people who already paid for architectural drawings. On top of that, if you're planning to use the ADU as a short-term rental, the city's business license process runs separately from the building permit, so you can get your certificate of occupancy and still not be legally allowed to rent it out yet.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 6-week permit timeline and $300/sqft figure are Brighton state-level estimates rather than verified local numbers, so I'd get quotes from two or three local contractors and call the Community Development department directly before penciling in a budget or start date. Even setting the cost question aside, six weeks assumes a clean, complete drawing set on first submittal — I've seen plenty of first-time applicants get bounced back for corrections, which can push the real timeline out by a month or more. — Charlotte Pemberton, Senior ADU Design Consultant"

Common Questions
Brighton Garage Conversion FAQs
Is a garage conversion allowed in Brighton? +
Yes — garage conversions are permitted in Brighton. 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 Brighton? +
Garage conversions in Brighton 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. 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 Brighton? +
Brighton'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 Brighton? +
Plan check in Brighton 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 Brighton? +
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 Brighton'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 Brighton? +
Our permit-ready garage conversion drawing packages for Brighton 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 Brighton'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 Brighton? +
A permitted garage conversion in Brighton 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.
