Detached Garages built by JMJ Construction in Northern Colorado

Overview

Custom detached garages built with the clearance and door configurations you actually need — RV height doors, pull-through bays, oversized widths, all available.

A detached garage gives you the workspace, storage, and clearance that a typical attached garage just can't match. Whether you need room for a daily driver and a project car, an RV and a boat, or a full multi-bay shop with a workshop attached, post-frame construction is the most economical way to get the size and clearance you actually want.

We build detached garages with the right ceiling height for vehicle lifts, the right door dimensions for RVs and trailers, and the right layout for how you'll actually use the space. Amarr overhead doors come standard — high-grade steel, robust designs, and the best insulation options on the market.

Single-bay, two-car, three-car, four-car, with workshop, with mezzanine, with attached lean-to, with full RV clearance — there's no template. Every detached garage is custom-designed to fit your site, your vehicles, and your budget.

Things to Consider

Plan ahead, build once

A few details to think through before you start. We'll walk through all of these on your consultation.

  • 01

    RV door height is the #1 thing people undersize. Measure the tallest point of your RV plus 1–2 feet.

  • 02

    Wider doors (10' or 12') make life easier for boats, trailers, and dual-rear-wheel trucks.

  • 03

    Pull-through layouts (doors on both ends) are great for RVs but cost more — decide early.

  • 04

    Setbacks and lot coverage rules vary by jurisdiction — we verify zoning compatibility before design.

Frequently Asked

Common questions about detached garages

How much does a detached garage cost?

+

A simple 2-car post-frame detached garage starts around $35,000–$55,000. A 3-car with workshop is typically $55,000–$85,000. RV-height multi-bay garages with full finishes run $90,000–$160,000+. We quote your specific build in detail.

How tall does an RV garage need to be?

+

Door height of 14' fits most travel trailers and Class C motorhomes. Class A motorhomes typically need 16' doors. Add 1–2 feet of clearance above the tallest item. Bring us your exact RV dimensions and we'll size correctly.

Can I add living quarters above my garage?

+

Yes — that's a common request. We can design with a full second story or partial mezzanine for living/storage. Apartment-over-garage builds need code review for egress, ceiling height, and utilities, but it's very doable in post-frame.

Detached garage vs. attached — which is better?

+

Detached gives you more flexibility on size, height, and use, and keeps shop noise/fumes away from the house. Attached is more convenient day-to-day but limited by your house's structure and setbacks. For RVs, big shops, and serious workspace, detached is usually the better answer.
