General Permit Information

A building permit is required anytime there is an addition, alteration, repair or demolition to the main structure or accessory structure on a lot or parcel.

The issuance of permits and subsequent inspections of the work performed ensures that all construction in the city is safe and in compliance with the City of Longmont Land Development and Building Codes. The primary purpose of these codes is to ensure a safe and healthy environment for the citizens of Longmont.

Permits are reviewed and issued at the Building Inspection Division office located at the Development Services Center, 385 Kimbark St. The office is open from 8:00 AM to 5:00 PM Monday through Friday. Call (303) 651-8332 for information.

As a homeowner you can act as your own contractor and do the work without a contractor's license on your own property where you live. However, if you subcontract a project, electrical wiring for example, then the subcontractor must be licensed to work in Longmont. You may as a homeowner be issued a permit for subcontracted work; however, you are also responsible for inspections and sign-offs on the permit card.

CAUTION: If you do work, or have any work done without obtaining a permit, you could be incurring liability in the event of a fire or accident related to the work. In some circumstances, your insurance could be invalidated.

Please Note:

    • NOISE. Section 10.20.100 of the Longmont Municipal Code prohibits making unreasonable noise which would cause a person of ordinary sensitivities significant annoyance and irritation.
    • CONSTRUCTION DEBRIS & TRASH. Section 9.04.100 of the Longmont Municipal Code requires debris and trash be contained on the job site.
    • BEFORE DIGGING. ALWAYS call the Utility Information Center at 1-800-922-1987 to locate underground utility lines. Allow 3 working days for the lines to be located and marked.
    • SMOKE ALARMS.Smoke alarms are required to be hardwired and interconnected in new and existing bedrooms, halls and one each level unless removal of interior wall or ceiling finishes would be required. In this case, battery operated devices are acceptable.

CALLING FOR INSPECTIONS

Requests for inspection are recorded on the Building Inspection Selectron system by calling (303) 774-4595. You will need your permit number and inspection card. Follow the voice mail prompts. Inspections are usually made on the following day, it is wise to anticipate when they need to be made to prevent delays.
No inspection will be made on subcontracted work done by an unlicensed subcontractor.

You should not proceed to cover-up any work that has not been inspected. You SHOULD NOT schedule any concrete or other major work for the same day as the inspection to avoid costly problems. Inspections must be called in the day before needed in order to efficiently schedule and route the Field Inspectors.

Please have all animals including dogs under control and not in the areas to be inspected. Inspections may not be made if there are animals running loose and a re-inspection fee may be required if this occurs.

Most patio covers and carports require three inspections. Please use the following information to plan for these:

General Information

DRAINAGE

Do not alter existing drainage patterns. Prevent run-off water from crossing onto adjoining properties.

SETBACKS
Structures which are more than 24" above grade must be placed within the minimum setback distances away from property lines, dependent upon the zone district in which they are located as specified in the Longmont Municipal Code Section 15.05.010.

ZONE DISTRICT SETBACK REQUIREMENTS

  EstateE1, E2 Residential
R1, R2, R3, RLE
Front Yard 30' 20'
Rear Yard 20' 20'
Side Yard One foot for every 2 1/2 feet of building height, height being measured from 1/2 the peak of the house to the ground.
Other Structures 6 feet away from sheds, detached garages, etc.
PLEASE NOTE: If the property is in a Planned Unit Development District (PUD), the setbacks are as specified on the Plat Map for the development. You may call Building Inspection for setback information.

WOOD SPECIES
Redwood is unsuitable for Structural Members (i.e. Beams, Joists and Ledger Boards, etc.) Redwood may be used for posts, roof sheathing more than 50% open, handrails and trim. Pressure treated or approved wood of natural resistance to decay must be used when the wood is in contact with concrete.

FOOTINGS/CAISSONS
The minimum depth is 30" to get below frost line; minimum width is 8". Footings/Caissons which support large loads, or constructed on poor soils may require different foundation designs.

POSTS
Posts are attached to the caissons below and the beams above with suitable anchors and brackets. Posts are 4"X4" minimum. Redwood may be used if it is relatively free of knots and splits. Otherwise, pressure treated lumber may be required.

LEDGER BOARD
The minimum ledger size shall be the same size as the rafters. Ledger boards are attached to the house with lag bolts that are at least 3/8" in diameter and long enough to go through the ledger board, siding, and they shall also penetrate fully into the rim joist or other backing inside the wall.
The new structure shall not bear on any part of a house cantilever.

SWAY/CROSS BRACING
These are placed diagonally between the posts and beams and may be required for covers and structures built high enough to cause sway.

BEAMS AND RAFTERS
Beam and rafter sizes are determined by a 30 psf. live load and a 10 psf. dead load, in combination with span lengths and roof area supported. Because there are many combinations of span and roof area, this pamphlet will not attempt to address all of these. The minimum sizes will be verified with the aid of a computer program by the Building Inspection office upon review of your project.

BEAMS
Beams are attached to posts below with suitable metal ties. Beams may cantilever out from support posts a maximum of 1'-0". Beams may be either one solid piece of lumber or more commonly, two boards of equal size may be attached together forming one solid member.

RAFTERS
Rafters may be attached on top of the Ledger Board or to the side with joist hangers. They may be attached on top of the beams with solid blocking between them. Another method of attachment is with joist hangers in order to be "flush" on top with the top of beam. In this case it is required that the beam be either one solid piece or two or more boards securely fastened together to form one solid member.

50% MINIMUM OPEN ROOF COVERING
Two inch nominal wood including Redwood may be used for "slat type" roofing provided the space between allows for at least 50% openness for snow to fall out and not build up a snow load.

ROOF SHEATHING AND ROOFING
Please refer to the Uniform Building Code for information on plywood, particleboard sheathing, or roofing information. Asphalt shingles must be fastened with a minimum of 6 fasteners and shall be hand or self sealing.

UTILITIES
Electric meter height must remain at 5'6" above grade. In the case of a deck, the finished floor of deck is considered grade.
Proper height of overhead service drop must be maintained:

TEMPERED GLASS
Windows within a 2'-0" arc of either vertical edge of doors and less than 5'-0" above the floor, require safety glazing.
