This page covers custom home construction, what's involved in the build process, how permits work locally, and why site-specific knowledge matters in Longmont.

How We Work

The build journey moves through distinct phases—planning, permitting, foundation and framing, mechanical and systems, finish work, and final walkthrough. Each step has a purpose.

Our Process in Six Steps

Custom home building starts with clarity. Before the first nail, we align on design intent, budget realities, site prep, and Longmont permit requirements.

1

Plan & Design

We review site conditions, understand your needs, and draft or refine plans. Longmont soil conditions and setback rules are factored in early.

2

Permits & Approvals

We pull permits through Longmont's Development Services Center. Multiple plot plans and specifications ensure compliance with local codes before work begins.

3

Foundations & Framing

Excavation, utility location, foundation, and frame go up on schedule. Inspections happen at each phase per Longmont requirements.

4

Mechanical & Systems

Electrical, plumbing, HVAC, and insulation follow rough frame. Licensed subcontractors are pulled for any specialized work per code.

5

Finish & Trim

Drywall, painting, flooring, cabinetry, and fixtures are installed. Quality checks at each stage ensure a clean final home.

6

Final Walkthrough

Longmont final inspection confirms all systems, finishes, and safety items are code-compliant. Certificate of occupancy is issued; you move in.

You'll always know what's happening next—and when.

We review your site, discuss possibilities, and point you toward realistic next steps before you invest in full design.

Why Local Knowledge Matters in Longmont

Longmont spans from historic downtown blocks built in the early 1900s to modern subdivisions in Somerset Meadows and West Saint Vrain. Building codes are consistent, but site conditions vary widely. We understand flood plain designations near St. Vrain Creek, typical soil types, utility easements, HOA rules in popular neighborhoods, and municipal noise ordinances.

That experience accelerates your project and prevents costly re-work.

Why It Matters

Permits Are Non-Negotiable in Longmont

All construction in the City of Longmont must comply with the City's Zoning and Building Codes, enforced through permits and inspections. We manage the entire permit process so you don't face delays or rework. Debris containment, noise limits, utility location calls, and inspection scheduling are handled by our team.

New residential construction, additions, ADUs, and electrical upgrades all require permits. The Building Inspection Division office is located at 385 Kimbark St. and is open 8 AM to 5 PM Monday–Friday.

Housing Stock Shapes Our Approach

Single-family detached homes are the most common housing type in Longmont, accounting for over 60% of the city's housing units. 61% of housing units were built between 1960 and 1999, meaning many properties have aging roofs, mechanical systems, windows, or deferred upkeep. New construction and thoughtful remodels are highly valued here.

Site-Specific Considerations

Longmont neighborhoods have distinct characters. Old Town near downtown Longmont features smaller lots and ornate historic homes. Somerset Meadows, five miles southwest, offers larger suburban parcels with new construction. West Saint Vrain near the Boulder County Fairgrounds is transitioning with modern infill. We tailor designs and permitting strategy to each area's existing patterns and zoning.

20+ Years of Local Building

We've completed 500+ projects across Boulder County. That experience translates to faster approvals, fewer surprises, and homes that fit their communities.

Frequently Asked Questions

Do I need a permit for a home addition or accessory building in Longmont?

Yes. New dwellings, garages, additions (patios, sunrooms, decks, pools, and accessory buildings greater than 120 square feet), and many alterations all require permits in Longmont. We handle the full application process at 385 Kimbark St.

What is an ADU and can I build one on my Longmont property?

An ADU is an accessory dwelling unit—a secondary home on your lot. Longmont adopted new ADU regulations on June 3, 2025, to comply with Colorado's HB24-11. Depending on your zone and lot size, you may be able to build a detached, basement, or garage-conversion ADU. We evaluate your property and guide you through the options.

How do I know if my site will work for custom home construction?

Site feasibility depends on lot size, zoning, setback requirements, utilities, soil conditions, and neighborhood character. We perform a walkthrough, check title and zoning, and review Longmont's planning maps to confirm your property can support your vision.

What does the permit review process look like in Longmont?

We submit plans with detailed plot dimensions, easements, and setback calculations to the Development Services Center. Permits are reviewed and issued at the Development Services Center, 385 Kimbark St., open 8 AM to 5 PM Monday–Friday. You can call (303) 651-8332 for information. We coordinate any resubmissions and schedule inspections.

Can I use my architect's plans or do we need new drawings?

We can work with existing plans, but they must be clear and compliant with Longmont codes. If revisions are needed, we coordinate them before permit submission to avoid delays and rework.

Do you work in other Boulder County areas outside Longmont?

Yes. We serve Longmont as our primary market but also take projects in nearby areas. Each jurisdiction has its own codes, so we evaluate every site and help you understand local requirements early.
