Based on El Paso County's local building codes, you'll need a permit when:
A concrete slab over 200 sq ft (or any slab intended as a foundation for a future structure) requires a building permit from PPRBD. Footings must extend below the 30 inch frost depth, reinforcement details per 2023 PPRBC R403 must be shown, and on expansive-soil sites a soils report may be required.
These concrete slab projects are typically exempt in El Paso County:

Required Documents for a Concrete Slab Permit in El Paso County

- Building permit application, For private property flatwork over exemption threshold. Filed by contractor or owner. Includes site plan, dimensions, purpose, estimated cost.
- Site plan, Drawing showing property boundaries, existing structures, slab location, distances to property lines and structures, slab dimensions, grade/drainage pattern. Can be hand-drawn for small projects.
- Encroachment / right-of-way permit application, For any work in public ROW (sidewalks, curb cuts, approaches). Filed with Public Works. Includes traffic control plan for street-adjacent work.
- Geotechnical soils report (expansive soil areas), Required for larger flatwork in areas with expansive clay soils (CA LA basin, Bay Area, TX DFW). Prepared by a registered geotechnical engineer. Specifies slab design requirements.
- Impervious surface calculation (where applicable), Shows existing impervious surface on the lot plus the proposed addition, and compares to the city's maximum allowance for your zoning district. Required in Austin, Portland, and other strict jurisdictions before approval.
- Elevation certificate (flood zones), For slabs in FEMA Special Flood Hazard Areas (SFHA). Shows proposed elevation relative to Base Flood Elevation (BFE). Required for any construction in flood zones.

Common Mistakes to Avoid in El Paso County
Skipping the permit for ROW work
The most common mistake for sidewalk replacements is thinking 'it's the sidewalk in front of my house, so I don't need a permit.' Wrong, the sidewalk is in the public right-of-way. Any work on it requires a permit from Public Works (not the building department). Unpermitted ROW work can result in fines, required removal, and liability for any injuries on the non-compliant surface.
Ignoring impervious surface limits
Austin, Portland, Seattle, and many coastal cities cap impervious cover on residential lots. Adding a large patio without checking your remaining impervious capacity can trigger a permit denial or an expensive stormwater management plan requirement. Check BEFORE designing.
Not checking for expansive soils
In LA basin, Bay Area, and DFW, expansive clay soils can cause slab heave if not properly designed. Standard 4-inch slabs on expansive clays can crack and lift within a few years. Engineered design (thickened edges, post-tension, or soils engineering letter) may be required. Skip this and you'll be repouring the slab in 3-5 years.
Slab too close to structure foundation
A slab placed tight against the house foundation can trap water against the foundation, causing basement moisture problems. IRC R401.3 requires drainage away from the foundation with minimum 6-inch fall in the first 10 feet. Slabs should slope away from the house at minimum 2% (1/4 inch per foot).
Wrong concrete mix for the climate
In freeze-thaw climates, air-entrained concrete is required for exterior flatwork. Non-air-entrained concrete spalls and cracks within a few winters. IRC R402.2 specifies 3,000-3,500 psi minimum for exterior flatwork in moderate/severe weathering zones. Always specify the correct mix when ordering.
No control joints
Concrete shrinks as it cures and cracks are inevitable. Control joints (scored lines) direct the cracking to predetermined locations where it's hidden. Without control joints every 10 feet maximum, the slab will crack randomly and unattractively. Cut control joints within 24 hours of pour or score during finishing.
Inadequate curing
Concrete must be kept damp for 7 days minimum to reach design strength. Drying too fast (especially in hot, windy weather) causes surface dusting, reduced strength, and premature cracking. Use curing compounds, plastic sheeting, or regular spraying.
Altering neighbor drainage
IRC R401.3 requires that drainage not be altered to direct water onto adjacent property. This is both a code violation and a tort liability issue. Plan the slab grade to maintain existing drainage patterns or include drainage mitigation (swales, French drains, catch basins).
Required Inspections in El Paso County
Most concrete slab projects in El Paso County require inspections at each construction stage:
Pre-pour inspection (for permitted work), Form dimensions and placement per approved plans, reinforcement type and spacing (if specified), vapor retarder installation (if required), base course thickness and compaction, proper grading for drainage, setbacks from property lines and structures.
Final inspection, Slab thickness, finish quality, control joints at proper spacing, drainage away from structures, no cracking beyond expected control joint lines, proper curing, compliance with approved plans.
ROW inspection (for sidewalks, curb cuts, approaches), Compliance with city standard details, proper slope and grade, ADA compliance (where applicable), integration with existing curb and sidewalk, no damage to adjacent public infrastructure.
Schedule inspections with Pikes Peak Regional Building Department (PPRBD) at (719) 327-2880 at least 24–48 hours in advance.
Pro Tips for Concrete Slab Permits in El Paso County
- For small at-grade patios (under 120 sq ft): the permit is often not required, but always call your building department to confirm. Five minutes on the phone saves weeks of back-and-forth later.
- For any ROW work: budget for Public Works approval BEFORE scheduling concrete work. Approvals can take 1-4 weeks and require engineering review.
- Save original receipts and plan documents. Future home buyers' inspectors may ask about slab installations, permit records help establish compliance.
- Before pouring a slab against a foundation, confirm the grading plan with your contractor. Slabs sloping TOWARD the house are a classic problem that leads to basement water intrusion.
- For stamped concrete: the finish quality depends heavily on the installer's experience. Budget extra for contractors with demonstrated stamped concrete portfolios. A bad stamp job is nearly impossible to correct without tearing out the slab.
- Control joints should be at least 1/4 of the slab thickness deep. For a 4-inch slab, joints should be 1 inch deep minimum. Deeper is better, the crack wants to propagate to the deepest weak point.
- Cold weather pouring: concrete needs protection from freezing for 3-7 days minimum. Use insulated blankets or heated enclosures. Pouring below 40°F requires special care.
- Hot weather pouring: concrete cures too fast, causing surface problems. Start early in the morning, use retarders, and cure immediately. Consider fog spraying to slow surface evaporation.
- For pool decks: coordinate with the pool contractor. The deck concrete is typically part of the pool building permit, and design needs to account for bonding, drainage, and chemical exposure.
- For DIY flatwork: start small. A 100 sq ft patio is a manageable weekend project with help. A 500 sq ft driveway is a major undertaking that benefits from professional help.
