Home Additions in Greenwood Village, CO

Home additions in Greenwood Village are shaped by the City’s large residential lots and generous setbacks. The Land Development Code sets principal building setbacks and height limits for each residential zone, and the Building Division adds survey checkpoints that verify an addition’s foundation and roof height during construction. We plan Greenwood Village additions around those numbers first, because they decide where an addition can go and how tall it can be before design gets far.

Setbacks in Greenwood Village’s Residential Zones

Greenwood Village’s residential zones are named for their minimum lot size, and the setbacks grow with the lot. In R-2.5 and R-2.0, principal buildings need 100 feet front and rear and 50 feet on each side. In R-1.5 and R-1.0, the numbers are 50 feet front and rear and 40 feet on the sides.

Smaller-lot zones are tighter. R-0.75 requires 40 feet in front and 20 feet at the rear and sides. R-0.5 requires 25 feet in front and 20 feet at the rear and sides. Some neighborhoods were approved as planned unit developments, which have their own setbacks; in R-2.0 and R-1.5, for example, the PUD standard is 50 feet front, 40 feet rear, and 40 feet side.

A deep setback can surprise owners of big lots, because a large yard does not always mean a large buildable area. We confirm the zone and any PUD standards for the property before sketching, then place the addition inside the allowed envelope.

Height Limits and How the City Measures Them

Height limits depend on the zone and sometimes on lot size. In R-2.5, R-2.0, and R-1.5, principal buildings may reach 30 feet on lots over 2.25 acres and 28 feet on lots of 2.25 acres or less. In R-1.0, the limit is 28 feet on lots over 0.8 acre and 26 feet on smaller lots. R-0.75 and R-0.5 cap principal buildings at 26 feet.

The City measures height from average grade. Its handout explains that the grade elevations at the four extreme corners of the foundation are averaged, leaving out decks, columns, and porches. Since January 1, 2013, existing grade has been based on a City-approved grading plan, or on the 1998 contours where no approved plan exists. Drawings show the roof peak and top of foundation as USGS elevations.

For a second-story addition, that math decides whether the design works. We calculate height the City’s way during design, not after framing.

Survey Checkpoints During Construction

Greenwood Village has added two checkpoints to its residential code. When the Planning Manager requires it, a foundation location and foundation height survey must be approved by Planning before any construction above grade, and before above-grade building inspections. When required, a roof ridge height survey must be approved before above-grade rough inspections.

The City’s residential submittal guidance also lists improvement location certificates and foundation and roof ridge height surveys. Together, these checks confirm that the addition was built where the plans placed it and no taller than allowed.

We build the surveyor’s visits into the schedule. Framing does not start until the foundation survey clears, and roofing and rough inspections wait for the ridge survey when the City requires one.

What Goes Into the Submittal

The City’s residential submittal guidance describes a full package. It lists a site plan showing the structure’s layout, dimensions, setbacks, and utility locations; architectural plans by a Colorado licensed architect; structural drawings stamped by a Colorado registered engineer; a soils report; and a foundation plan that includes a peripheral drain system. Mechanical, electrical, and plumbing plans, Manuals J, D, and S, and REScheck complete the technical set, along with a waste management plan and a South Metro Fire Rescue permit application.

That list is written for new residential projects, so we confirm which items apply to a specific addition with the City. Structural design follows the City’s design criteria, including a 30 psf ground snow load and 36-inch frost depth. The Municipal Code’s table and the submittal page list different wind speeds, 100 mph and 120 mph, so we confirm the value with the Building Division.

The City lists the 2018 residential and energy codes and the 2023 electrical code. Colorado’s HB22-1362 requires stronger energy codes when cities update, and we did not find a date for Greenwood Village’s next update, so we confirm editions at submittal.

HOA Approval and Variances

Many Greenwood Village neighborhoods have HOA covenants, and HOA approval is on the City’s submittal list where it applies. The HOA runs its own separate review. The City’s variance guide is direct: City approval of a variance does not mean the HOA has approved the plans.

If an addition cannot meet the Land Development Code, the owner can revise the design or apply for a variance. The Board of Adjustments and Appeals hears variances in a public hearing. The process starts with a pre-application meeting and a look at design alternatives with Planning staff. The application fee is $50, the submittal must be complete at least 30 days before the hearing, and neighbors and the HOA must be notified at least 15 days ahead. The Board meets on the fourth Thursday of each month, except November and December. These details come from the City’s 2023 variance guide, so confirm current fees and deadlines with Planning.

We look for a design that fits the rules first, since that is usually faster than a hearing.

Floodplain, Grading, and Site Work

Several Greenwood Village zoning standards say no structures are permitted in a floodway or area of special flood hazard, including the R-0.5 district and the PUD standards in R-2.0, R-1.5, and R-1.0. Floodplain permits are processed under the City’s Drainage Criteria Manual. We check flood maps early for any lot near a drainage.

Grading can need its own approval. For developed single-family homes, the City requires a sitework permit when landscaping involves structures, patios, walls, or berms, changes drainage paths, moves more than 10 cubic yards of soil, or covers an acre or more. An addition’s excavation and regrading can reach those thresholds.

Fire sprinklers are a separate question. The City’s code does not require a new sprinkler system for additions to existing homes that do not already have one.

How We Sequence a Greenwood Village Home Addition

We start with the zone, setbacks, height limit, and any PUD or HOA standards, then check for flood hazard and grading thresholds. Design follows inside that envelope, with height calculated from average grade. We assemble the soils report, stamped drawings, energy documents, and the rest of the submittal, confirm code editions, and file through the Online Access Portal.

After the permit is issued, our crew excavates and pours the foundation, and the foundation survey is approved before framing. Framing, roofing, and rough-ins follow, with the ridge survey approved when required before rough inspections. Insulation, drywall, and finishes come next, and the addition closes with final inspection and the City’s certificate.

Common Questions

What are the setbacks for an addition in Greenwood Village?
They depend on the zone. R-2.5 and R-2.0 require 100 feet front and rear and 50 feet on the sides. R-1.5 and R-1.0 require 50 feet front and rear and 40 feet on the sides. PUD neighborhoods have their own standards.

How tall can a home addition be in Greenwood Village?
Limits range from 26 to 30 feet depending on the zone and lot size, measured from the average grade at the four corners of the foundation.

Why does Greenwood Village require surveys during construction?
When the Planning Manager requires them, a foundation location and height survey and a roof ridge height survey must be approved before certain construction and inspections, confirming the addition matches the approved plans.

Does City approval cover my HOA in Greenwood Village?
No. The City’s variance guide states that City approval does not imply HOA approval. Homes under HOA covenants need the HOA’s separate approval.
