Home Additions in Black Forest, CO

Home additions in Black Forest sit at the intersection of two agencies: the Pikes Peak Regional Building Department reviews the building plans, and El Paso County Planning & Community Development sets the zoning that controls where an addition can sit on a rural-residential lot. Black Forest’s large, forested acreage parcels and its wildland-urban-interface location add setback and wildfire-mitigation questions that a typical suburban addition never faces. Our crew plans Black Forest additions around both.

Setbacks on Rural-Residential Acreage

Most Black Forest parcels fall under El Paso County’s Rural Residential zoning, and the county’s Land Development Code sets clear dimensional standards for the two most common designations here. In the RR-5 district (5-acre minimum lot size), the front, rear, and side setbacks are each 25 feet, maximum lot coverage is 25%, and maximum height is 30 feet. In the RR-2.5 district (2.5-acre minimum lot size), front and rear setbacks are also 25 feet, but the side setback drops to 15 feet, with no stated maximum lot coverage and the same 30-foot height limit.

These figures come directly from the county’s zoning table, but they are general standards, not a substitute for confirming the exact zoning on a specific parcel. Some Black Forest properties carry forestry or agricultural designations with their own setback figures, and we verify the parcel’s actual zoning district with El Paso County before an addition’s footprint gets finalized.

The Plan Package PPRBD Requires

An addition cannot be reviewed as a walk-through submittal — PPRBD requires a full plan package. That includes a scaled plot plan showing property lines and front, rear, and side yard dimensions, the property’s tax schedule number, a foundation plan, complete architectural floor plans for each level including the addition and adjacent existing spaces, floor and roof framing plans, and exterior elevations showing finished grade, floor and plate heights, and roof slope.

PPRBD also requires a “Solar Ready” roof plan: where a roof slope falls between 110 and 270 degrees from true north and exceeds 600 square feet, the plan must show at least 300 square feet of solar-ready zone, in areas at least 5 feet in dimension and totaling 80 square feet or more. That requirement applies to the addition’s new roof even on a home with no current plans to install solar.

Soils Report and Engineered Foundation

PPRBD states plainly that “structures will be required to have a soils report and engineered foundation design at the time of first inspection.” On Black Forest’s varied terrain — sloped lots, exposed granite outcrops, and soil types that differ significantly across the area — that requirement is not a formality. We build the soils report into the schedule at the start of design, not as a scramble before the first foundation inspection.

Any structure using unconventional construction — earth-sheltered or bermed design, log construction, structural insulated panels, or similar methods sometimes chosen on large rural lots — requires plans sealed by a Colorado-licensed design professional, on top of the soils and foundation engineering.

Solar-Ready, Energy Code, and Electrical Requirements

Additions fall under the 2021 IECC and the currently adopted electrical code. PPRBD’s plan requirements call for an Energy Conservation Code certificate or REScheck printout, lighting controls meeting 2021 IECC R404.2 and R404.3, and — if EV-ready wiring is included — a minimum 2-pole 40-amp GFCI breaker with conduit, conductor, and receptacle stubbed to a garage parking space. Hot water pipe insulation, air barriers behind electrical boxes in the thermal envelope, and water-closet clearances per the 2021 IRC are all called out on the plumbing and electrical plan checklists.

A second kitchen or kitchenette within the addition — common when an addition is designed as a guest suite or in-law space on a large Black Forest lot — needs Zoning Authority approval separate from the building permit, and may be restricted depending on the property’s zoning.

Wildfire Resiliency Code and the WUI

El Paso County’s Planning and Community Development office has stated in an official policy letter that the 2025 Colorado Wildfire Resiliency Code goes into effect July 1, 2026, and applies to buildings and structures within the wildland-urban interface — a designation that covers Black Forest’s heavily forested terrain. Until the county formally adopts the code’s official map, county staff use a Vegetation Map to determine whether a project needs a Wildland Fire and Hazard Mitigation Plan, prepared by a qualified professional and covering fuel management, defensible space, and structure hardening.

Whether this requirement extends to an addition on an existing home, as opposed to new subdivision development, is not spelled out in the county’s letter, so we confirm applicability with the county for any specific Black Forest addition before assuming it does or doesn’t apply. Black Forest’s own wildfire history — the area burned significantly in 2013 — is part of why this question is worth asking early rather than at final inspection.

Fees and Plan Change Procedures

PPRBD’s plan review fee for an addition is calculated as a percentage of the building permit fee, based on the square footage of proposed construction, under the department’s current fee schedule. Changes to an approved, permitted plan cost $50 per hour, payable before the next inspection, and a plan needing a fourth review or later is billed at $100 per hour for each additional review. A post-permit plan change, called a “splice,” carries a minimum $50 fee.

We build in a realistic plan-review buffer rather than assuming the first submittal will sail through, since PPRBD requires a complete initial review cycle before any corrections can be picked up and resubmitted.

How We Sequence a Black Forest Home Addition

We start by confirming the parcel’s zoning district and setbacks with El Paso County, checking whether a Wildland Fire and Hazard Mitigation Plan applies, and ordering the soils report early enough that engineering doesn’t hold up the plan set. We assemble PPRBD’s full addition package — plot plan, foundation plan, floor and framing plans, solar-ready roof plan, and energy documentation — and submit it as a complete set the first time.

After permits are issued, foundation work follows the engineered design and passes its first inspection against the soils report, then framing, rough electrical, rough plumbing, and rough mechanical proceed in PPRBD’s required order. Insulation and drywall follow approval, and the project closes with a final inspection once the addition matches the permitted plan.

Common Questions

What are the setbacks for a home addition in Black Forest?
It depends on the parcel’s zoning. Under El Paso County’s Land Development Code, RR-5 lots (5-acre minimum) carry 25-foot front, rear, and side setbacks, while RR-2.5 lots (2.5-acre minimum) carry 25-foot front and rear setbacks with a 15-foot side setback. We confirm the exact zoning district for the parcel before finalizing a footprint.

Does a Black Forest addition need a soils report?
Yes. PPRBD requires a soils report and engineered foundation design to be in place by the time of the first foundation inspection, which matters on Black Forest’s varied terrain and soil conditions.

Does the Colorado Wildfire Resiliency Code apply to my addition?
El Paso County has stated the 2025 Colorado Wildfire Resiliency Code takes effect July 1, 2026, and applies to buildings in the wildland-urban interface, which covers Black Forest. Whether it applies to an addition on an existing home specifically should be confirmed with the county before design is finalized.

Can a home addition include a second kitchen or guest suite?
A second kitchen or kitchenette with a permanent 220-volt or gas cooktop, stove, or range requires separate approval through the Zoning Authority, and depending on the property’s zoning it may be restricted or require modification.
