Local Intelligence
What Northglenn Homeowners Need to Know Before Submitting
Size & Zoning Rules
Converting your garage to a legal rental unit means the finished space must comply with Northglenn's ADU size limits. Northglenn's current ADU size cap is 750 sq ft — on the tighter end, which constrains larger conversion plans.
Northglenn 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 Northglenn can command approximately $1,418/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
Building Division permit fees for this project type typically range from $2,114 to $7,201 depending on project valuation and scope. Plan check runs approximately 5 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Garage conversion drawings submitted to Building Division 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 Division ↗Construction Cost Context
Northglenn'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 Northglenn
Northglenn's Building Division requires a separate Adams County septic or tap-fee verification before they'll even log your ADU application, and if your lot was platted before the city's 1980s annexation records were digitized, tracking down that utility history can stall submission by several weeks on its own. Many of the older subdivisions near Grant Park also carry duplicate title restrictions from the original developer that predate current city zoning, so homeowners often need a title company search to confirm an ADU isn't blocked by a covenant the city itself doesn't enforce or track. Because the city allows short-term rentals, plan for a separate business license and rental inspection after your certificate of occupancy — a step people frequently forget to budget time for.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 5-week plan check and $300/sqft figure are Northglenn state-level estimates, not gospel — real submittals with incomplete drawing sets routinely push past 8-10 weeks, so I'd get local contractor quotes and call the Building Division directly before penciling in a start date. — Charlotte Pemberton, Senior ADU Design Consultant"

Common Questions
Northglenn Garage Conversion FAQs
Is a garage conversion allowed in Northglenn? +
Yes — garage conversions are permitted in Northglenn. 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 Northglenn? +
Garage conversions in Northglenn typically range from $85,000 to $187,000 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 Northglenn? +
Northglenn'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 Northglenn? +
Plan check in Northglenn typically takes approximately 5 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 Northglenn? +
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 Northglenn'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 Northglenn? +
Our permit-ready garage conversion drawing packages for Northglenn 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 Northglenn'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 Northglenn? +
A permitted garage conversion in Northglenn adds rentable square footage to a home currently valued around $380,000. 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.
