Denver Pool Site Plan for Permit: Setbacks, Barriers and Equipment Location

Installing a backyard pool involves more than selecting its shape and deciding where the patio should go. Denver’s permit review considers the pool’s position, distances from property lines and buildings, safety barriers, equipment location, utilities, sewer lines and drainage conditions.

A clear Denver pool site plan brings this information together on one scaled drawing. It helps the property owner, pool contractor and city reviewer understand exactly what is proposed before excavation begins.

Does a Swimming Pool Require a Permit in Denver?

Denver distinguishes between permanent and temporary pools. According to the City and County of Denver, pools installed as permanent structures require zoning and sewer use and drainage permits. Interior pools and exterior in-ground pools also require building permits.

A temporary pool that will be removed at the end of the season does not generally require these permits. However, a pool intended to remain permanently on the property should be reviewed under Denver’s permanent-pool requirements.^[1]

A residential pool project may involve several separate approvals:

• Zoning permit: Reviews the location of the pool, barriers, fences and mechanical equipment.
• Building permit: Required for an interior or exterior in-ground pool.
• Sewer use and drainage permit: Reviews sewer, water, drainage and floodplain considerations.
• Electrical permit: Required for pool-related electrical work.
• Plumbing permit: May be required for recirculation piping, gas piping and heaters.
• Mechanical or boiler permit: May apply to certain pool-heating equipment.

Denver allows zoning, building and sewer use and drainage reviews to occur simultaneously when a complete application package is uploaded at the beginning of the process.^[1]

What Must a Denver Pool Site Plan Include?

Denver requires a pool site plan to be drawn to scale and to include the drawing scale and a north arrow. The plan should provide labels and dimensions for:

• All primary, side and rear zone-lot lines;
• Adjacent streets and alleys;
• Existing buildings, accessory structures and driveways;
• The proposed pool’s overall dimensions;
• Distances between the pool and property lines;
• Distances between the pool and existing structures;
• Pool fences and other required barriers;
• Gates and controlled access points;
• Pumps, filters, heaters and related equipment; and
• Water, storm-sewer and sanitary-sewer lines.

Denver also requires drawings covering the pool’s electrical and mechanical equipment. These drawings may need to identify the equipment’s size, type, power requirements, filtration system, chemical system, location and maintenance-access area.^[1]

Show the Pool Setbacks Clearly

A setback is the required distance between the proposed pool and a regulated property feature, such as a zone-lot line. The applicable setback can depend on the property’s zone district, lot configuration, neighborhood context and other site-specific conditions.

For that reason, a pool site plan should not use a generic setback copied from another Denver project. The designer should identify the property’s zoning, review the applicable requirements and dimension the proposed pool accordingly.

Setback dimensions should be shown from the nearest relevant portion of the pool to the applicable zone-lot line. The plan should also show distances to the house, garage, retaining walls and other structures when those relationships affect construction or code compliance.

Denver requires a boundary survey when any part of the pool or its equipment will be located within three feet of a property line.^[1] This requirement is particularly important on narrow urban lots where fences, landscaping and existing paving may not accurately identify the legal boundary.

Do Not Assume a Fence Is the Property Line

An existing fence is not necessarily located on the legal lot boundary. It may sit several inches or feet inside one property, follow an old occupation line or have been installed without a survey.

If the proposed pool, decking, fence or equipment pad will be close to a boundary, reliable boundary information is essential. A licensed land surveyor may be required to establish or certify the legal property lines.

Denver Pool-Barrier Requirements

Pool barriers are a core life-safety requirement. Denver’s current building code applies the barrier provisions of the International Swimming Pool and Spa Code, with local amendments.

Under Denver’s local amendments, the top of a required pool barrier must generally be at least 60 inches above grade when measured from the side facing away from the pool. The required height must be maintained around the barrier’s perimeter and through the specified exterior clearance area.^[2]

The code also establishes separation between the water and the pool-side face of the barrier. Denver’s amendment states that the pool or spa side of the required barrier must be at least 48 inches from the water’s edge. The inside of a qualifying mesh fence must likewise be at least 48 inches from the nearest edge of the water.^[2]

A permit site plan should therefore show:

• The complete barrier around the pool area;
• The barrier’s relationship to the pool and water’s edge;
• All gates and pedestrian entrances;
• Doors or windows providing direct access from the house;
• Any section where the house wall forms part of the barrier;
• The location of an approved pool safety cover, when proposed; and
• Nearby walls, retaining walls or objects that could affect the barrier.

Gates, Doors and Access Points

Access gates should be clearly identified on the plan. Their design must comply with the applicable pool-barrier provisions, including required closing and latching protection.

If a wall of the house forms part of the pool barrier, doors, gates or low windows that provide direct pool access require additional protection. Depending on the approved design, Denver’s code provides options that can include listed water-hazard entrance alarms, an approved ASTM F1346 safety cover or another approved protection method such as self-closing doors with self-latching devices.^[2]

Because the acceptable arrangement depends on the complete barrier design, the site plan should accurately show the relationship between the pool, house and every access point.

Pool Equipment Location

The equipment pad is not a minor detail to be added after the pool location is approved. Denver requires pool-related mechanical equipment to be included in the zoning review, and the permit documents must identify the proposed equipment and its location.^[3]

A complete equipment layout may identify:

• Pool pump;
• Filtration system;
• Heater or boiler;
• Electrical disconnects and controls;
• Recirculation piping;
• Gas lines, when applicable;
• Chemical-treatment equipment;
• Equipment slab or pad;
• Required working and maintenance space; and
• Screening or enclosure around the equipment.

The equipment should be located where it remains accessible for maintenance while complying with zoning, electrical, plumbing and mechanical requirements. The design should also consider noise, drainage, ventilation and proximity to neighboring properties.

Equipment should not be shown inside an easement or over known utility and sewer lines unless the appropriate authority has confirmed that the placement is allowed.

Electrical and Mechanical Information

Pools require careful coordination between the site plan and the trade drawings. Denver’s permitting guide states that electrical work requires an electrical permit. Pool heaters, boilers, gas piping and recirculation piping may require plumbing, mechanical or boiler permits depending on the installation.^[3]

The equipment drawings should provide enough information for reviewers to understand:

• The equipment being installed;
• Electrical power requirements;
• Heating and filtration systems;
• Equipment-control locations;
• Maintenance access;
• Connections to building systems; and
• The relationship between equipment and the pool.

The basic site plan establishes where the equipment will be placed. Detailed electrical, plumbing or mechanical drawings may still be required separately.

Utilities, Sewers and Easements

Pool construction involves substantial excavation, making underground conditions particularly important. Denver instructs applicants to identify the size, type and location of water, storm-sewer and sanitary-sewer lines on the site plan for sewer use and drainage review.^[1]

Before finalizing the pool location, check for:

• Sanitary-sewer service lines;
• Storm drains and drainage facilities;
• Water-service lines;
• Gas and electrical utilities;
• Utility and access easements;
• Roof and surface-drainage paths;
• Existing retaining walls; and
• Floodplain restrictions.

Denver notes that additional sewer use and drainage requirements can apply when excavation occurs within two feet of a sewer line. Projects in a regulatory floodplain can also require additional review.^[1]

Excavation and Shoring

An in-ground swimming pool requires excavation that may affect nearby soil, structures and property lines. Denver directs applicants to submit a shoring plan when the project’s excavation conditions require one.

The need for shoring can depend on excavation depth, soil conditions, proximity to buildings and the distance between the excavation and property boundaries. The site plan helps establish these relationships, but engineering or additional construction documents may be required for the excavation itself.

Special Conditions That Can Affect Approval

Some Denver properties need additional review beyond the standard pool-permit process.

Historic Districts and Landmarks

An in-ground pool project at an individually designated landmark or within a local historic district can require Landmark Preservation review and a Certificate of Appropriateness. Denver recommends obtaining this approval before applying for zoning and building permits.^[1]

Designated Parkways

If the property adjoins a designated parkway and the proposed work encroaches into the parkway setback, an exception request may be necessary.

Floodplains

A property within a regulatory floodplain can be subject to additional development and drainage requirements. The pool’s excavation, equipment and surrounding improvements should all be evaluated.

Retaining Walls and Grade Changes

Pool construction may involve retaining walls, raised decks or substantial grading. These features should appear on the site plan because they can affect drainage, barrier height, access and structural review.

Applying Through Denver’s E-Permits System

Denver issues pool permits electronically. Applicants submitting zoning, building and sewer use and drainage materials should select “Building Log” in the e-permits system.^[1]

Submitting a complete package at the beginning can reduce avoidable review delays. The package may include:

• A scaled site plan with a north arrow;
• A boundary survey when required;
• Pool dimensions and construction information;
• Barrier, gate and access details;
• Electrical and mechanical equipment drawings;
• Utility and sewer information;
• An excavation or shoring plan when required;
• Energy-code compliance information;
• Landmark approval when applicable; and
• Applicable trade-permit documentation.

Eligible owners of single-family homes may be able to apply for residential permits without a general contractor. Denver requires an owner-occupier to be the legal owner and resident, provide matching identification and follow additional rules. Homeowners performing electrical, plumbing or mechanical work may need to pass the applicable examination or use properly licensed contractors.^[4]

Common Pool Site Plan Problems

Pool applications are more likely to need corrections when the drawing:

• Uses a fence as the assumed property boundary;
• Omits the drawing scale or north arrow;
• Does not show dimensions to property lines;
• Leaves out the pool barrier or gates;
• Does not show the equipment pad;
• Places equipment within an easement;
• Omits sewer and utility information;
• Fails to identify direct access from the house;
• Does not include a required boundary survey; or
• Uses outdated or generic setback information.

Order a Denver Pool Site Plan

A properly prepared site plan makes it easier to identify zoning, barrier, utility and equipment-placement issues before excavation begins. It also gives Denver reviewers a clear overview of the proposed project.

Site Plan Pros can prepare an easy-to-read plan using available property records and the project information you provide. If the city requires a certified boundary survey, structural engineering, shoring design or professionally sealed trade drawings, those services must be obtained from the appropriate licensed professional.

Frequently Asked Questions

Does an in-ground pool require a building permit in Denver?

Yes. Denver states that exterior in-ground pools require a building permit in addition to zoning and sewer use and drainage permits.

Does a temporary seasonal pool require a permit?

Denver states that temporary pools removed at the end of the season do not require the permanent-pool permits described on its residential pool page. Safety and other applicable property requirements should still be considered.

When is a boundary survey required?

Denver requires a boundary survey when any part of the pool or related equipment is within three feet of a property line.

How high must a Denver pool barrier be?

Denver’s current local code amendment generally requires the top of the barrier to be at least 60 inches above grade when measured from the side facing away from the pool or spa. The entire barrier design must comply with the applicable code provisions.

Can the house form part of the pool barrier?

It may, but doors, gates and qualifying windows that provide direct access to the pool require approved protective measures. These can include alarms, an approved safety cover or another approved protection method.

Does the pool equipment need to appear on the site plan?

Yes. Denver asks applicants to show fences, barriers and all related equipment. Separate electrical and mechanical equipment drawings may also be required.

Can a basic site plan replace a boundary survey?

No. A basic site plan can illustrate the proposed work, but it does not establish or certify legal property boundaries. Obtain a licensed boundary survey when Denver requires one or when the boundary location is uncertain.
