USA Site Plans
Planning to install a residential swimming pool in Philadelphia? A pool can make a backyard more enjoyable, but it also adds important site planning issues. The City may need to understand where the pool will be located, how deep it is, how it will be enclosed, where the equipment will go, how water will drain, and how the pool fits with property lines, fences, patios, garages, alleys, and existing structures.
A Philadelphia pool site plan helps show the full backyard layout for the proposed swimming pool. It can include the existing house, proposed pool footprint, pool deck, equipment pad, property lines, setbacks, fence or barrier, gate locations, drainage direction, walkways, garage, shed, driveway, and nearby site features.
This guide explains what a Philadelphia pool site plan should include, when permit and safety requirements may apply, what homeowners should prepare, and how to avoid common pool layout mistakes.
What Is a Philadelphia Pool Site Plan?
A Philadelphia pool site plan is a scaled drawing that shows the proposed swimming pool on a residential property. It is usually drawn from above and shows how the pool fits into the backyard or side yard with the existing home, property lines, fencing, equipment, patio, deck, garage, alley, and other features.
A pool site plan may show:
- property lines and lot dimensions;
- existing house footprint;
- proposed swimming pool location;
- pool length, width, and shape;
- pool depth note if known;
- pool deck or patio area;
- pool equipment pad;
- fence or barrier enclosure;
- self-closing and self-latching gate locations;
- front, side, and rear setbacks;
- distance from pool to property lines and structures;
- walkways, stairs, gates, and access paths;
- garage, shed, driveway, alley, or fence locations;
- drainage direction and slope;
- north arrow and scale.
The purpose is to make the pool layout easy to understand. A reviewer, contractor, or homeowner should be able to see where the pool will be installed, how large it is, how the yard will be enclosed, where the equipment will sit, and how the pool affects the rest of the property.
Does a Pool in Philadelphia Need a Permit?
It depends on the type of pool. Philadelphia’s Administrative Code lists an exception for prefabricated swimming pools accessory to one- and two-family occupancies when the pool is less than 24 inches deep, does not exceed 5,000 gallons, and is installed entirely above ground.
Official source: Philadelphia Administrative Code – Application for Permit
That means a small, shallow, above-ground prefabricated pool may be treated differently from a deeper above-ground pool, in-ground pool, spa, hot tub, or permanent pool installation. If the pool is deeper, permanent, connected to utilities, includes a deck, requires excavation, or changes the site layout, permit review may be needed.
Philadelphia’s zoning permit guidance also lists swimming pools installed on the property of a one- or two-family dwelling among work that does not require a zoning permit. However, building code, safety, barrier, electrical, plumbing, historic, floodplain, and stormwater requirements may still apply depending on the project.

Before installing a pool, homeowners should confirm the exact permit path for their project. A small seasonal pool is not the same as an in-ground pool with equipment, decking, wiring, plumbing, fencing, and drainage work.
Pool Safety Barriers in Philadelphia
Pool safety is a major review issue. Philadelphia’s property maintenance code states that pools, hot tubs, and spas containing water more than 24 inches deep must be completely surrounded by a fence or barrier at least 48 inches high above the finished ground level, measured on the side away from the pool. Gates and doors in those barriers must be self-closing and self-latching.
Official source: Philadelphia Property Maintenance Code – Swimming Pools, Spas and Hot Tubs
Because of this, a pool site plan should not only show the pool. It should also show the enclosure, fence line, gate locations, and access route. A pool without a clear barrier layout can create review questions and safety issues.
Why a Pool Site Plan Matters
A pool affects more than the area filled with water. It can change the yard layout, drainage, safety enclosure, utility routing, patio area, access path, and relationship to neighboring properties.
A clear Philadelphia pool site plan helps show:
- where the pool will be installed;
- how large the pool will be;
- whether the pool is in-ground or above-ground;
- how far the pool is from property lines;
- where the pool deck or patio will be located;
- where the pool equipment will sit;
- how the pool area will be enclosed;
- where gates and access paths will be located;
- how stormwater and drainage will be handled;
- whether the pool affects a garage, shed, fence, alley, driveway, or nearby structure.
A good site plan helps organize the entire pool project before construction starts. It also helps prevent expensive mistakes, such as placing equipment too close to a boundary, forgetting gate access, or directing water toward the house.
Common Philadelphia Pool Projects
Pool site plans can help with several types of residential pool projects.
In-Ground Pool
An in-ground pool usually requires excavation and a more detailed plan package. The site plan should show the pool footprint, property lines, pool deck, fence or barrier, equipment pad, drainage direction, and nearby structures.
Above-Ground Pool
An above-ground pool may still need review if it exceeds the small-pool exception, is deeper than 24 inches, includes equipment, has a deck, or becomes a more permanent backyard feature. The site plan should show the pool location, access, barrier, equipment, and drainage.
Pool Deck or Patio
Many pools include a deck, patio, paver area, concrete apron, or sitting area. That hardscape should be shown on the site plan because it affects access, drainage, and usable yard area.
Pool Equipment Pad
The pump, filter, heater, and related equipment should be shown. Equipment location matters for access, noise, electrical work, plumbing, and safety.
Pool Fence and Gates
If a new fence, gate, or barrier is needed, show it clearly. Pool barrier requirements are a key safety issue.
Hot Tub or Spa
Hot tubs and spas can also trigger barrier, electrical, structural, and safety requirements. If the project includes a hot tub or spa, show it on the site plan.
What Should a Philadelphia Pool Site Plan Include?
A permit-ready pool site plan should be clear, scaled, and specific to the property. It should show the actual backyard and the actual proposed pool, not a generic pool diagram.
1. Property Lines
The site plan should show the front, side, and rear property lines. These boundaries help explain where the pool sits on the lot and how close it is to neighboring properties.
If the pool is near a fence, remember that the fence may not be the exact legal property line. If the pool location is tight, use a survey before final placement.
2. Existing House
The existing house should be shown and labeled. Most residential pools are located behind or beside the home, so the plan should show the rear wall, doors, steps, basement access, and nearby walkways when relevant.
3. Proposed Pool Footprint
The proposed pool should be clearly labeled. The site plan should show the pool length, width, and shape.
For example, the plan may show a 16-foot by 32-foot in-ground pool, a circular above-ground pool, or a custom pool shape. The site plan dimensions should match the pool contractor’s drawings and permit documents.
4. Pool Depth
Pool depth is important because Philadelphia’s permit exception for prefabricated above-ground pools is tied to a depth of less than 24 inches. The site plan or notes should identify the depth when relevant.
5. Pool Setbacks
The plan should show how far the pool is from property lines and nearby structures. Important dimensions may include:
- distance from pool to rear property line;
- distance from pool to side property lines;
- distance from pool to the house;
- distance from pool to garage, shed, or deck;
- distance from pool equipment to property lines;
- distance from pool deck or patio to fences and structures.
Philadelphia’s Building Code section on swimming pool enclosures and safety includes location rules for in-ground swimming pools, so pool-to-property-line dimensions are important for in-ground projects.

6. Pool Deck or Patio Area
If the pool includes a surrounding patio, concrete apron, paver area, or deck, show it on the site plan. The deck or patio affects walking space, drainage, hard surface area, access, and the overall backyard layout.
7. Pool Equipment Area
The equipment pad should be shown clearly. This may include:
- pool pump;
- filter;
- heater;
- salt system or chlorinator;
- electrical panel or shutoff if known;
- equipment base or pad;
- access path for maintenance.
Equipment should not be an afterthought. It is part of the pool system and should be coordinated with the site layout.
8. Fence or Barrier Line
The site plan should show the fence or barrier that encloses the pool area. If an existing fence will serve as part of the barrier, label it clearly. If a new fence is proposed, show the new fence line.
For pools over 24 inches deep, Philadelphia requires a fence or barrier at least 48 inches high with self-closing and self-latching gates or doors.
9. Gates and Access Paths
Gate locations should be shown clearly. The plan should identify how people enter and exit the pool area.
Show:
- main pool gate;
- side-yard gate;
- rear alley gate if present;
- walkway from house to pool;
- access path to equipment pad;
- gate swing direction if useful.
10. Drainage Direction
Pool projects can change how water moves across the yard. The site plan should show drainage direction, slope, and any nearby drainage features.
Water should not be directed toward the house foundation, neighboring property, garage, basement entry, or low areas where water can collect.
11. Existing Garage, Shed, Driveway, or Alley
Many Philadelphia properties have tight backyards, rear garages, alleys, sheds, and paved access areas. The site plan should show these features when they are near the pool.
This helps confirm that the pool does not block access, interfere with a gate, or create unsafe circulation.
12. North Arrow and Scale
A north arrow and scale make the site plan easier to read. They also make the drawing look more professional and permit-ready.
Pool Barrier and Gate Layout
The barrier layout is one of the most important parts of a pool site plan. A pool drawing that only shows the water area is incomplete for practical planning.
The barrier section of the plan should show:
- fence or wall line around the pool area;
- height note for the barrier;
- gate locations;
- self-closing and self-latching gate note;
- existing fence sections to remain;
- new fence sections to be installed;
- house wall used as part of the enclosure if applicable;
- access from the house to the pool area;
- access to pool equipment.
If the pool enclosure depends on an existing fence, verify that the fence actually meets pool barrier requirements before relying on it.
Pool Equipment Location
Pool equipment is often forgotten until late in the project. The equipment pad should be part of the site plan from the beginning.
The plan should show:
- equipment pad size;
- pump and filter location;
- heater location if included;
- distance to property lines;
- distance to the house and pool;
- access path for service;
- electrical or plumbing route if known;
- screening or fence relationship if relevant.
Equipment placement can affect noise, maintenance, safety, utility work, and neighbor concerns.
Pool Decks, Patios, and Hardscape
Many pool projects include a patio, pool deck, concrete apron, pavers, seating area, or walkway. These surfaces should be shown because they affect drainage and hardscape coverage.
Important hardscape details include:
- pool deck width;
- patio dimensions;
- walkway locations;
- steps or landings;
- surface material;
- drainage direction;
- relationship to the house and garage;
- distance to property lines.
If the pool deck is being built with the pool, include it as part of the same site layout.
Pool Drainage and Stormwater
Pool projects can affect stormwater and drainage. Excavation, pool decking, patios, and equipment pads can change how water moves through the yard.
The Philadelphia Water Department’s Stormwater Management Guidance Manual explains stormwater review requirements and helps applicants determine whether a project is regulated.
Official source: Philadelphia Water Department – Stormwater Management Guidance Manual
For a pool site plan, helpful drainage details include:
- general slope direction;
- where pool deck runoff will go;
- existing and proposed hard surfaces;
- downspouts near the pool area;
- nearby drains or drainage features;
- low spots where water may collect;
- relationship to neighboring property;
- how water will be kept away from the house foundation.
If the project creates a large amount of hard surface or changes the grade significantly, more detailed stormwater or drainage documentation may be required.
Pool Near a Garage, Shed, or Alley
Many Philadelphia lots include a detached garage, shed, driveway, alley, or shared access area. If the pool is near these features, the site plan should show them clearly.
The plan should identify:
- garage footprint;
- shed location;
- rear alley or shared access route;
- driveway or parking area;
- pool fence and gate relationship;
- equipment access path;
- distance between pool and nearby structures;
- drainage direction near the garage or alley.
The pool area should not block practical access to the garage, gate, equipment, or rear yard.
In-Ground Pool vs. Above-Ground Pool
The site plan should identify the pool type because different pools can raise different permit and layout issues.
In-Ground Pool
An in-ground pool usually requires excavation, permanent construction, equipment, decking, barrier layout, and more detailed planning. The site plan should show the pool footprint, property line distances, pool deck, equipment pad, fence, gates, and drainage direction.
Above-Ground Pool
An above-ground pool may still need careful planning. If it is deeper than the small-pool exception, includes equipment, has a deck, or remains as a seasonal or permanent backyard feature, confirm whether permit or safety requirements apply.
Hot Tub or Spa
Hot tubs and spas should be shown on the site plan when included. They can affect electrical work, barrier requirements, structural support, access, and drainage.
Electrical, Plumbing, and Utility Work
Many pool projects include electrical, plumbing, and equipment work. This can include pumps, filters, heaters, lights, bonding, grounding, gas lines, or water supply connections.
If utility work is part of the project, the site plan or supporting drawings should show:
- equipment pad location;
- electrical equipment location;
- pool light or wiring route if known;
- gas heater location if included;
- plumbing route if known;
- distance to house and property lines;
- utility meter or service location if relevant.
Electrical and plumbing work may require separate trade permits or contractor documentation.
Other Drawings That May Be Needed
A pool site plan may be only one part of the permit package. Depending on the project, additional drawings or documents may be needed.
Possible supporting documents include:
- pool construction plan;
- pool depth profile;
- pool equipment plan;
- pool barrier or fence detail;
- gate detail;
- electrical plan;
- plumbing plan;
- grading and drainage plan;
- pool deck or patio plan;
- manufacturer specifications;
- photos of existing conditions;
- historic or floodplain documents if required.

Historic Properties and Floodplain Review
If the property is on the Philadelphia Historic Registry or located in a floodplain, special review may apply. Philadelphia’s building permit page notes that some projects that might otherwise be exempt from a building permit may still require one if the property is on the Philadelphia Historic Registry.
Official source: City of Philadelphia – Get a Building Permit
Pool projects in special review areas should be checked before excavation, equipment installation, or construction begins.
Pool Site Plan vs. Survey
A pool site plan is not the same as a survey.
A survey is prepared by a licensed surveyor and identifies legal property boundaries, existing improvements, and other boundary-related information. A site plan is a project drawing that shows the proposed pool layout on the property.
For a pool project, boundary accuracy is important. If the pool, pool deck, equipment, or fence is close to a property line, a survey can help prevent mistakes.
Common Philadelphia Pool Site Plan Mistakes
Many pool project delays come from unclear or incomplete site information. Avoid these common mistakes:
- property lines not shown;
- pool footprint not dimensioned;
- pool depth not identified when relevant;
- pool equipment area missing;
- fence or barrier layout missing;
- gate locations missing;
- pool deck or patio area not shown;
- setbacks from property lines not labeled;
- garage, shed, alley, driveway, or fence missing;
- drainage direction ignored;
- utility work not disclosed;
- using a fence line as the property line without verification;
- historic or floodplain status not checked;
- no north arrow or scale;
- using a rough sketch that is hard to read.
A good pool site plan should show the entire pool area, not just the water outline.
What to Gather Before Preparing a Philadelphia Pool Site Plan
Before preparing the drawing, gather the basic property and project information.
Helpful items include:
- property address;
- existing survey if available;
- lot width and lot depth;
- pool type: in-ground, above-ground, hot tub, or spa;
- pool length and width;
- pool depth;
- pool deck or patio dimensions;
- pool equipment pad location;
- fence and gate layout;
- existing house footprint;
- garage, shed, driveway, alley, fence, and gate locations;
- walkways, stairs, and access paths;
- drainage direction or slope information;
- photos of the backyard;
- whether the pool includes electrical, plumbing, heating, or lighting;
- whether the property is historic or in a floodplain;
- zoning district if known.
The more accurate the starting information, the cleaner the site plan will be.
How to Apply for Philadelphia Permits Online
Philadelphia uses eCLIPSE for online permit and license applications. Applicants can use the City’s online system to apply for permits, upload documents, and manage permit activity.
Official source: City of Philadelphia – eCLIPSE
Before submitting, make sure the pool site plan, project description, pool dimensions, barrier layout, equipment information, and supporting drawings all match. Inconsistent information can lead to corrections.
When a Pool Site Plan Is Especially Helpful
A detailed pool site plan is especially useful when:
- the pool is in-ground;
- the pool is deeper than 24 inches;
- the pool includes a deck or patio;
- the pool requires new fencing or gates;
- the pool equipment is close to a property line;
- the yard is narrow or irregular;
- the project includes electrical, plumbing, or heating equipment;
- the pool is near a garage, shed, alley, or driveway;
- drainage or runoff is a concern;
- the property is historic or in a floodplain;
- the homeowner wants a cleaner permit package.
In these situations, a simple sketch may not be enough. A scaled, labeled site plan can make the pool layout easier to review and easier to build correctly.
Final Thoughts
A Philadelphia pool site plan is an important drawing for residential swimming pool projects. It shows the proposed pool footprint, property lines, setbacks, pool deck, equipment area, fence or barrier, gate locations, drainage direction, existing house, garage, driveway, shed, and nearby site features.
Small prefabricated above-ground pools may qualify for permit exceptions only when they meet Philadelphia’s stated conditions. Deeper pools, in-ground pools, hot tubs, spas, pools with decks, and projects with equipment, utilities, fencing, grading, or drainage work may require more detailed review.
Before installing a pool, confirm the permit requirements, verify the property layout, plan the safety barrier, locate the equipment carefully, and prepare a clear site plan that shows exactly how the pool fits in the backyard.
