Permit Thresholds
Wheat Ridge permit thresholds
- Code reference
- Retaining walls over 4' high (or supporting a surcharge) and other structural elements like decks or room additions explicitly require permits; any structural work in a remodel would qualify as an alteration requiring a permit.
- Code reference
- These requirements are enforced under the City of Wheat Ridge Municipal Code, Chapter 5, Article II, Division 2 (Building Permits).
- Use tax
- Per City Code Section 22-68, use tax is charged at 3.5% of 60% of the project valuation (60% of valuation is assumed to be materials subject to tax).Section 22-68
- Code reference
- Permit fees are based on the higher of the applicant’s valuation or the building official’s minimum (using ICC Building Valuation Data); a separate plan review fee (65% of the permit fee) applies where required.
Codes are amended regularly — verify current requirements with **City of Wheat Ridge Building Division (City of Wheat Ridge, Colorado) issues residential building permits.
Energy Code
Wheat Ridge energy code quick facts
- Code reference
- 2024 IECC (with Colorado Model Low Energy and Carbon Code, 2025 edition, and Colorado Model Electric Ready and Solar Ready Code), adopted by reference with primarily administrative/local amendments (no technical energy amendments noted).
- Code reference
- This replaces the prior 2018 I-Codes.
- Code reference
- City Council approved on October 27, 2025 (Ordinance 1883); the 2024 codes (including 2024 IECC, excluding Chapter 1 but retaining Sections C102, R102, C107, and R107) apply to all new permit applications beginning January 1, 2026.Ordinance 1883
- Code reference
- Wheat Ridge is in Climate Zone 5B.
- Code reference
- Requirements for remodels/additions generally follow the 2024 IECC (and Colorado model code) provisions applicable to existing buildings (often via IEBC cross-references or specific existing-building sections), with no local technical amendments identified that alter prescriptive values.
- Code reference
- Specific numeric prescriptive requirements (e.g., R-values, U-factors, air-sealing thresholds) are those in the base 2024 IECC/Colorado model code for CZ 5B; local adoption does not modify them.
- Permit-related tax/fee (construction use tax)
- Use tax of 3.5% applied to 60% of the project valuation (separate from and in addition to the building permit fee, which is calculated via a tiered schedule based on valuation).
- Code reference
- Adopting references include Chapter 5 of the Wheat Ridge Municipal Code (incorporating the listed codes by reference) and Ordinance 1883.Ordinance 1883

When a second-story addition makes sense
A second-story addition adds bedrooms, a primary suite, office space, or other living area without expanding the home’s footprint. It is often considered when side-yard setbacks, lot coverage limits, a detached garage, or outdoor living priorities make a rear or side addition less practical. In the Denver metro, many homes on smaller lots or in established neighborhoods face those constraints. Vertical expansion can preserve yard space while increasing finished square footage, but it is a structural project—not a cosmetic remodel. The existing foundation, first-floor walls, floor framing, and roof system all have to support new loads.
text
What the work typically includes
Scope varies by home and design, but second-story additions commonly involve: - Structural evaluation of the foundation, bearing walls, and first-floor framing - Temporary protection and weatherproofing while the existing roof is opened or removed - New floor framing, exterior walls, windows, and a new or modified roof - Stairs or stair reconfiguration to reach the new level safely and code-compliantly - Exterior finishes that tie into existing siding, masonry, or stucco - Electrical, plumbing, and HVAC extension into the new space by licensed specialty trades - Insulation, drywall, flooring, and interior finishes - Updated smoke/CO detection and means-of-egress details required for the new sleeping or living areas Some projects build over an existing single-story wing; others raise a portion of the home and rework the roof lines around the addition. Matching floor elevations, stair placement, and exterior proportions early reduces costly redesign later.
text
Structural and design checks before you commit
Before drawings are finalized, the existing structure needs a clear assessment. Key questions include whether the foundation and first-floor bearing lines can carry the added dead and live loads, whether posts, beams, or sistered joists are required, and how lateral loads (wind and seismic design categories applicable locally) will be handled in the new wall and roof diaphragm. Denver-metro housing stock ranges from mid-century ranches to newer two-story production homes. Older homes may need more framing reinforcement, foundation work, or selective demolition to create clean bearing paths. Design also has to address head height at stairs and eaves, window placement for light and egress, and how the addition reads from the street so massing does not overwhelm the original house. Energy code requirements affect wall and roof assemblies, window performance, and how the new conditioned space connects to the existing thermal envelope. Those choices should be settled in design, not improvised in the field.
text
Living in the home during construction
Second-story work is disruptive. Opening the roof, removing ceiling finishes below bearing lines, and running new stairs often affect the main living level. Dust control, temporary weather barriers, and phased access plans matter as much as the finish schedule. Some households relocate for part of the build; others stay and wall off work zones. Expect periods without normal use of rooms under the addition, intermittent utility shutoffs when trades tie in new systems, and restricted yard or driveway access for material staging. A written phasing plan—what stays occupied, where temporary protection goes, and how the home is dried in—should be part of project planning.
text
Permits and coordination in the Denver metro
Second-story additions require building permits and plan review. Submittals typically include architectural and structural drawings, and may include energy compliance documentation and public-tree or zoning clearances depending on the property and scope. Roof structure, stair geometry, egress windows in sleeping rooms, guardrails, and smoke detection are common plan-review focus areas. A municipally licensed Denver general contractor coordinates the project, permit process, inspections, and licensed specialty trades such as electrical, plumbing, and HVAC. Individual trade permits are pulled and inspected under those specialty licenses as required by the city or county. HOA architectural review, if applicable, runs in parallel with municipal permitting and should be started early so exterior materials and height are not reworked after permit drawings are complete.
text
Cost factors without a one-size number
Second-story addition cost is project-specific. Major drivers include: - Structural reinforcement needed at the foundation and first floor - Size and complexity of the new level, including roof form and exterior finish matching - Stair location and whether existing halls or rooms must be reconfigured - Extent of work required on the level below for beams, posts, or ceiling repair - Mechanical strategy—extending existing HVAC versus adding capacity or zoning - Window and exterior material choices - Site access, temporary protection, and whether the household will occupy the home during construction - Local permit, design, and engineering requirements Because those variables differ by house, proposals should follow on-site evaluation and schematic design rather than a generic per-square-foot assumption.
text
How to prepare as a homeowner
Clear goals help the design team size the addition correctly: who will use the space, whether a full bath is required, storage needs, and whether future resale layout matters as much as immediate use. Gather any existing plans, survey work, prior remodel permits, and HOA guidelines before the first site visit. Also note known issues—settlement cracks, past roof leaks, undersized electrical service, or aging HVAC—that could surface when the structure is opened. Sharing those details early keeps structural and mechanical scope realistic.
FAQ
Common questions
Can my existing foundation support a second story?
Not always without reinforcement. A structural evaluation looks at foundation type and condition, soil bearing assumptions, and how new loads transfer through the first floor. Some homes need added footings, beams, posts, or wall reinforcement; others can accept the load with more limited framing upgrades. That determination belongs in design, before demolition.
Will we need to move out during a second-story addition?
It depends on the roof opening sequence, stair work, and how much of the main level is affected. Some owners stay with temporary barriers and phased work; others relocate during demo, framing, and dry-in. Ask for a phasing and protection plan so occupancy expectations are explicit.
Who handles the trade permits and licensing?
A municipally licensed Denver general contractor coordinates the project and inspections. Licensed specialty trades handle electrical, plumbing, HVAC, and other regulated scopes, including the trade permits those disciplines require.
How long does a second-story addition usually take?
Duration depends on size, structural complexity, weather during roof-open work, permit review time, and finish level. Design and permitting often take a substantial period before construction starts. Construction itself commonly spans several months once work begins; your schedule should be built from the actual drawings and municipal review timeline, not a generic estimate.
Do second-story additions require new stairs?
Most do, unless an existing stair already lands where the new floor can connect cleanly. Stair placement affects hallways, closets, and rooms on the first floor, and the stair must meet current code for rise, run, headroom, and guards. Resolve stair location in schematic design because it drives both structure and daily circulation.
What surprises homeowners most on these projects?
Conditions hidden above ceilings and in bearing walls—older framing, prior undocumented remodels, or limited capacity for new point loads—are common discovery items once the structure is opened. Exterior matching, temporary weather protection, and the amount of first-floor repair under new beams are also easy to underestimate without thorough design.
