Lafayette, Colorado Building Permit Guide

The City of Lafayette Building Division, at City Hall on South Public Road, issues every building and trade permit inside city limits and takes applications only through its Online Service Portal. Fees follow a valuation table with a plan check fee of 65% on top, simple “quick permits” are processed in about 2 business days, and a new house takes 8 to 12 weeks to get first review comments.

What requires a permit in Lafayette?

Lafayette requires a building permit to construct, enlarge, alter, repair, move, demolish or change the occupancy of any building or structure in the city. The same permit requirement covers new electrical, gas, mechanical and plumbing systems and additions, alterations or replacements to existing ones.

Demolition has an extra step. Any demolition permit for a structure 50 years old or older is reviewed for historic significance first, and the Historic Preservation Commission can put a stay of up to 90 days on the permit.

Who issues building permits in Lafayette?

The Building Division, part of the Planning and Building Department, issues building permits, carries out inspections with the City’s own inspectors, licenses contractors and keeps building records for property inside Lafayette city limits. Land in unincorporated Boulder County next to the city is permitted by Boulder County’s Building Safety and Inspections division instead.

Lafayette permit types and the Online Service Portal

Permits, development projects, inspections and contractor licences are all handled in the Online Service Portal, which runs on GovBuilt. Create an account before you apply. Active permits and licences were moved over from the old MyGov system, and MyGov access ends at the end of December 2026, so download any records you still need from it before then.

Quick permits are for contractors and skip plan review: staff confirm the selected contractor licences are in good standing, then process the permit. Filing a commercial addition, new commercial or new multi-family permit before the site plan and civil approvals are in hand pushes those estimates back.

Homeowner permits. You can pull a permit for your own primary residence without a contractor licence. Rental properties do not qualify and must list a general contractor. Any subcontractor a homeowner hires has to hold a City of Lafayette licence.

Contractor licences. Everyone paid to do construction work in the city needs a Lafayette licence, applied for in the portal under Licenses & Registrations and valid for one year. The City must be named as certificate holder on the general liability certificate.

Lafayette permit fees and project charges

The City’s Building Permit Fees schedule dated January 1, 2026 bases the permit fee on the total value of the work: materials, labor, overhead and profit for the building, electrical, mechanical and plumbing scopes together. Fees are due when the permit is issued, except quick permits, which are paid at application.

For example, a $50,000 remodel that goes through plan review has a permit fee of $712.20 and a plan check fee of $462.93, plus $1,161 in city use tax and $400.50 in county use tax.

New homes carry further charges on the same schedule, collected with the permit: an affordable housing fee of $1 per sq ft (unfinished basement included), a $250 engineering inspection fee, a $1,750 stormwater utility fee, a $7,500 service expansion fee, a $1,350 parks and recreation fee and a $150 public arts fee for a single-family house, along with a $1,000 building permit commitment deposit per unit. A 3/4-inch water tap is $20,300 with a $346 meter, and the matching water reclamation tap is $6,350. Properties outside the city boundary pay twice the in-city tap fees.

Card payments are limited to Visa and Mastercard, and a permit bill of $10,000 or more has to be paid by check or wire transfer.

Electrical, plumbing, mechanical and gas permits in Lafayette

Trade permits come from the same Building Division, and Lafayette’s own inspectors inspect them. Stand-alone electrical, plumbing, mechanical, furnace, AC and water heater jobs are quick permits in the portal unless they involve solar or engineered plans, which go to plan review. Electrical work is inspected to the 2026 National Electrical Code and plumbing to the 2024 International Plumbing Code.

The fee schedule lists a temporary electrical permit at $33 and electrical re-inspections at $75 each. Other re-inspections, after-hours inspections (2-hour minimum) and extra plan review caused by plan changes are billed at $75 per hour.

The Lafayette Fire Department charges its own construction inspection fee on non-residential work: $350 for a new core and shell building of up to 15,000 sq ft, rising by floor area above that, and $50 for a tenant finish of up to 1,500 sq ft plus $0.033 for each additional sq ft.

Documents and plan-review submissions in Lafayette

Everything is submitted electronically, and incomplete submittals are not accepted. The Building Division publishes a 2026 checklist for each common project: accessory dwelling unit, accessory structure, basement, commercial tenant finish, deck, fence, new residential, solar PV, patio enclosure, patio cover or carport, sign, and window and door.

Residential remodel plans may be no larger than 11 by 17 inches; all other plan sets may be up to 24 by 36 inches. New residential and commercial buildings also need a Utility Service Application, plus a right-of-way permit for work in the right-of-way and grading, erosion control and stormwater quality permits once 1 acre or more is disturbed.

Lafayette’s published design criteria are a 36-inch frost depth, a 40 psf roof and ground snow load and a 145 mph wind speed.

How to apply: 6 steps in Lafayette

Lafayette construction inspections

Inspections are booked only in the Online Service Portal, in the Inspections module under the permit. Request by 3 p.m. for the next business day. Inspections happen between 9 a.m. and 4 p.m.; call 303-661-1451 between 8 and 9 a.m. on the day for your arrival window, and use the same number to cancel by 9 a.m.

Someone aged 18 or over has to be at the address to give access, and inspectors will not go into an occupied home without the owner or the owner’s representative present. If the inspection record card or the stamped approved plans are missing, the inspection is not done and a $75 re-inspection fee may be charged. Approved inspections are signed off on the front of the permit card, and corrections are left in writing on the card or on yellow Lafayette inspection tags.

A Certificate of Occupancy is issued for new single-family homes and additions to them, each unit of a new two-family home or townhome, each new multi-family building, new commercial buildings and their additions, and changes of occupancy.

Local Lafayette filing details that matter

Old Town Neighborhood Overlay: additions, duplexes, garages, ADUs and other accessory structures in Old Town must meet the overlay’s extra checklist on top of the building permit items. It starts with a meeting with planning staff about the architecture and asks for scaled elevations showing height, materials and window area, plus a site plan with lot coverage, setbacks and significant trees. An ADU there is capped at 750 sq ft.

Buildings 50 years or older: demolition needs the Historic Preservation Demolition Review Application, and a stay issued by the Historic Preservation Commission can be appealed to City Council.

Fences: under Municipal Code Section 26-14-7, fences and walls may not be taller than 6 feet, must sit at least 12 inches from a public sidewalk and are limited to 36 inches inside a sight vision clearance area. The owner is responsible for locating the property lines.

Energy code: Lafayette enforces the Metro Cohort Model Code, built on the 2024 International Energy Conservation Code, and its new-home checklist asks plans to show a PV-ready roof area, an EV-ready garage receptacle and electric-ready circuits for space and water heating.

Wildfire mapping: state mapping places 128 acres of Lafayette in low or medium wildfire risk, 44 acres of open space on the southeast edge and 84 acres on the west side near Nyland Way and Brittney Lane, where new construction must use non-combustible materials.

Water service: a property must be inside the Northern Water conservancy district boundary before the City will serve it.

Colorado building code

Colorado has no statewide building code for private buildings: each city and county decides whether a code applies and which edition, while the state sets electrical and plumbing rules, a minimum energy code on any update, and a wildfire code for the mapped wildland-urban interface.
