When Does a Denver Fence Permit Apply?
FenceOwl Team · October 13, 2026 · 9 min read

A Denver fence permit is the city's check before the posts go in, and you do not need one for every fence. The City and County of Denver says fences over four feet need a zoning permit. Fences shorter than four feet generally do not, unless the house is a landmark, sits in a historic district, or the run follows a designated parkway. This guide covers that split, the height line at the front of the house, and what you upload. It is not a permit. Confirm your lot on the city's page before anyone orders boards.
When a Denver fence permit is required
Start with height, then with the status of the house. On an ordinary lot, a fence at four feet or under can go up without a zoning permit. Cross four feet and the zoning permit applies. The same page says walls, including retaining walls, need a zoning permit once they are over twelve inches.
Three places skip the height shortcut. Any fence or wall in a historic district, on an individually designated landmark, or along a designated parkway needs a permit no matter how low it is. A three-foot front fence on a landmark block is still a review. A neighbor off the district is not your precedent.
Industrial lots use a different table: seven feet inside the setback and ten feet outside it. A house is not that table. Stay with four feet in front and six feet in back unless the city has given you something else in writing.
Fence estimates in Denver start when you trace your own line. Draw it, then ask which parts sit in front of the house.
The front of the house sets the height
Denver does not measure every edge of a lot the same way. Outside industrial areas, the maximum is four feet in the front yard and six feet in the backyard. The city defines the split from the primary street-facing facade: the wall that faces the primary street, often the wall with the front door. Fences in front of that point stay at four feet or shorter. Fences behind that point can be up to six feet.
That is why a wrap around a Denver house changes at the front corner. A wood picket or another open fence often fits the street face. A solid craftsman cedar privacy fence is the usual side-yard and rear-yard choice, where six feet and a closed board are allowed. Cedar dog-ear privacy is the same family with a different top.
Taller than those maximums is not a guess. The city's fences page points to section 10.5.5 of the Denver Zoning Code for over-height fences and walls. Read that section, or ask the permit desk, before you plan a privacy wall past the posted maximum.
A corner house makes the front harder. More than one street may read as a front, and the facade rule still starts from the primary street. Do not assume the alley and the side street are both back yards. Ask which edges are primary, side, and rear before you order a tall run along the sidewalk.
A zoning permit and a building permit are different
All fences over four feet need a zoning permit. A post-hole fence, the usual wood or chain-link job, needs a building permit only when it is taller than eight feet. Other fence and wall types need a building permit when they are over four feet. Masonry walls and retaining walls over six feet also need commercial engineering plan review and a building permit.
A six-foot cedar privacy fence of posts and boards on a normal lot is a zoning permit, not a building permit, because it is under eight feet. A masonry wall over four feet needs the building permit as well. A retaining wall over twelve inches is already in zoning review, and over six feet it is an engineered building project. Say "posts and boards" if that is the job. Say block, stone, or a wall holding soil if it is not.
Denver's e-permits guide tells you which log to open. Use a zoning permit when only zoning is required. Some fences may be eligible for a permit without plan review. Use the building log when a building permit is required, or when you need both. First-time users create an account, then go to Development Services and Apply for a Permit. When the prompt asks, select zoning permit for the zoning-only path.
Aurora and Lakewood sit next door and run their own desks. A Denver approval does not travel with you across the city line.
What the site plan has to show
The permit is mostly a drawing. Denver's fences page says the site plan should label and dimension every zone lot line, show how far the fence sits from those lines, include a north arrow, name the streets and alleys, show the structures already on the lot, and mark the proposed location, height, and materials. If the fence mixes materials, sits on a retaining wall, or is over height, they also want an elevation: a side view that shows the height. A fence that needs a building permit needs section and footing details too.
The city's homeowner fence instructions walk through the clicks and ask for that packet as a PDF. The sample site plan shows a scale and the distance from the zone lot line. A front run at four feet and a rear run at six feet should read as two pieces, not one note that says "fence." Count the gates. A walk gate and a drive gate change the opening. If you are unsure which edge is the primary street, use the zone-lot tip sheet linked from the fences page before you label the plan "front."
Historic districts, landmarks, and parkways
Landmark status changes the permit even when the fence is short. Landmark Preservation reviews fences, retaining walls, and hardscape on individual landmarks and inside a historic district. Plantings are outside that review. A new patio or pergola next to the fence can pull the project into a larger review.
The height rules are written down. Front-yard fences may not be higher than four feet and must be more than half open. Rear-yard fences may not be higher than six feet and may be solid. Vinyl, PVC, and chain link are not allowed in most historic districts and on most individual landmarks. A vinyl privacy fence or galvanized chain link that would be fine on another block can be the wrong material here. Black vinyl-coated chain link is still chain link. Check the district before you fall in love with a photo.
A fence that meets the design guidelines may use landmark quick review. The city says those applications are typically processed within a few business days after a complete packet arrives. A fence tied to a retaining wall is not on that quick path.
The e-permits choice is Landmark Certificate of Appropriateness. The packet wants a dimensioned site plan, elevations that note height and materials, and current photos of the work area and the street facade. Label photos with north, south, east, or west. For a proposed rear fence over six feet and under eight, the city asks for photos from at least three neighboring properties, with a measuring tape on the fence. That is how a taller rear fence gets considered. It is not an approval.
A designated parkway adds Denver Parks and Recreation, with its own setbacks. The fences page already requires a permit at any height on a parkway. Look the street up before you treat a tree lawn as yours to fence.
Sidewalks, floodplains, and the sewer
The fence has to stay off land that is not yours. Denver says not to build on a neighbor's property or in the public right-of-way, which includes streets, alleys, sidewalks, and tree lawns. Every fence and wall must sit at least six inches back from the public sidewalk, no matter where the property line is. Measure from the concrete. An old post may already be too close. Show the sidewalk on the site plan and dimension the gap.
If the lot is in a floodplain, or you will dig within two feet of the sewer line, the city says a sewer use and drainage permit may be required. The fences page points you at property research for that check. Do it before the holes are on the calendar.
Talk to the neighbor when the line is shared. Agree on the face, the gate swing, and what happens to the old fence. An HOA can be stricter than the city on color, material, and height. Get that answer in writing. City approval does not cancel an HOA denial, and an HOA letter does not replace the Denver fence permit when the city wants one.
Mark the utilities before anyone digs
A permit does not find the gas line. Colorado 811 says every owner contacts them before digging, including fence posts, and that no dig is too small or too shallow. The locate is free. It covers public gas, electric, water, sewer, and communications. Sprinklers and other private lines are not on the ticket.
811 tells homeowners to make contact at least three business days ahead and to wait three full business days, not counting the day of the request. State law requires notice at least two business days before excavation, not including the day of notice. Use the longer wait 811 publishes, and track the ticket until the utilities respond. Denver Water says that same three-business-day contact applies to fence posts, and that you read the positive response before you excavate. Old paint is not a current ticket. If a mark is missing, stop and ask for a new locate.
How the permit sits next to the estimate
Length, height changes, and gates are the facts on both the permit drawing and the quote. How an estimate works is the short version: trace the yard, pick a style, tell us where to send it, and the number shows then. What drives the fence cost in Denver is that line.
The visit still checks the property line, the sidewalk gap, the slope, and whether a truck can reach the run. If the house might be a landmark, say so before the style is locked. Vinyl that is fine on one block can be off the table two streets away.

Questions homeowners ask
Does every new fence in Denver need a permit?
No. The city's fences and walls page says fences shorter than four feet do not require a permit, unless the site has landmark or historic status. A fence along a designated parkway needs a permit at any height. Confirm the lot before you order materials.
How tall can a fence be in a Denver front yard?
Outside industrial areas, the city says the maximum is four feet in front of the primary street-facing facade and six feet behind that point. A taller fence needs the over-height path in the zoning code. This page is not that approval.
Is a zoning permit the same as a building permit?
No. Fences over four feet need a zoning permit. A post-hole fence needs a building permit only when it is taller than eight feet. Other fence and wall types need a building permit when they are over four feet. The city's fences page is the checklist.
Can I use vinyl or chain link in a Denver historic district?
Landmark Preservation says vinyl, PVC, and chain link are not allowed in most historic districts and on most individual landmarks. Front-yard fences there may not be higher than four feet and must be more than half open. Check the district before you pick a picture.
Who marks the utilities before the posts go in?
Colorado 811 marks public lines, and the locate is free. The association tells homeowners to contact them at least three business days before digging, for a project of any size. Private lines, such as sprinklers, are not part of that locate.
