Denver Site Plan – $89, 24‑Hour Delivery, Pass Denver P&D Review
Permit‑ready residential and ADU site plans for Denver homeowners, contractors, and builders. You submit the address. We deliver a PDF that passes. No learning curve.
Denver’s Community Planning & Development (P&D) enforces the Denver Zoning Code (DZC), the 2025 Building Code, and specific drainage and stormwater regulations. The most common permit delays do not come from major design flaws. They come from missing details on the site plan. A missing setback dimension, an ADU size that exceeds the zoning allowance, a stormwater note omitted – each one can add weeks to your timeline.
We draft reviewer‑ready site plans in 24 hours. Upload your address. We pull parcel data, verify setbacks, size limits, utility access, and required drainage notes – then deliver a PDF ready to attach to your permit application.
- 24‑hour turnaround for most residential plans
- Fixed pricing – $89 to $249
- Free revisions if the city asks for changes
Why Denver Permits Get Delayed (And How We Prevent It)
Denver reviews site plans against the Denver Zoning Code, the 2025 Building Code, and sewer use and drainage (SUDP) requirements. Reviewers reject plans for the same small omissions again and again.
Setback dimension missing or measured incorrectly. Denver requires setbacks to be measured from the furthest projection – eaves, gutters, chimneys, bay windows. Foundation measurement is automatically wrong.
ADU size, height, or placement exceeds zoning allowance. ADUs must be smaller than the primary dwelling and built within specific setbacks. A two-story ADU requires a 20-foot rear setback, and detached ADUs must fit within the rear 35% of the lot. Omit these details, and the plan is rejected.
Flood zone reference missing. Denver enforces floodplain regulations through Chapter 114 of the City Code. Even in Zone X, the FEMA panel number is required.
Grading and stormwater information incomplete. The city requires a sewer use and drainage permit (SUDP) for pools, ADUs, and any project that alters existing drainage. Missing flow arrows or a stormwater narrative triggers a correction.
Utility connection points not shown. Water, sewer, gas lines must be located. The reviewer cannot approve what they cannot verify.
Parking and driveway layout missing. The Denver Zoning Code requires specific driveway width, alley access where available, and off-street parking for ADUs and new construction.
Lot coverage calculation wrong or missing. Denver enforces lot coverage limits per zoning district. Exceed the cap, or omit the calculation, and the plan stops.
We include everything on the checklist before you submit – so you avoid the resubmission queue and the hidden costs of a correction cycle.
What We Include – And Why It Matters to Denver Reviewers
You do not need to learn the Denver Zoning Code. We do. Every Denver site plan we deliver includes:
| Element | Why Denver Reviewers Check It |
|---|---|
| Property lines from recorded plats | GIS data is often rounded. Reviewers cross-check against the recorded plat. We use legal dimensions. |
| Setbacks measured from the furthest projection | Denver measures to eaves, overhangs, and chimneys – not the foundation wall. Foundation measurement is rejected. |
| Easements with book/page numbers | “Utility easement” alone is insufficient. We add the recorded instrument number. |
| ADU size, height, and placement | ADUs must comply with zoning allowances: size limits, height limits, and rear setback requirements (10 ft for 1‑story, 20 ft for 2‑story). We verify before submission. |
| Flood zone with FEMA panel number | Required even for Zone X. We reference the correct panel. |
| Grading, drainage, and stormwater notes | References SUDP and stormwater standards, including flow direction and runoff management. |
| Utility connection points | Water, sewer, gas shown with connection locations. |
| Lot coverage calculation | Matches your zoning district limit. |
| Driveway and parking layout | Width, alley access, and off-street parking shown per code. |
| North arrow and engineering scale | Required on every sheet. |
| Denver Assessor parcel number | Mandatory for all site plans. |
You do not need to understand any of this. We handle it.
What Denver Reviewers Commonly Flag – Real Correction Examples
Here is what actual correction letters from Denver P&D look like – and how we prevent them:
“Missing setback dimension – side property line. Measured from foundation, not eave.”
We include all setback dimensions (front, side, rear) measured from the furthest projection. Foundation measurement never passes.
“ADU size exceeds zoning allowance. Primary dwelling allows X sq ft. ADU exceeds limit.”
We verify ADU size against the primary dwelling and Denver Zoning Code before submission. If the site does not support the proposed size, we notify you before you pay.
“Flood zone reference not provided. FEMA panel number required.”
We add the panel number and zone (e.g., “Zone X, Panel 08001C0385J”) even for low‑risk properties.
“Grading and drainage information incomplete – stormwater management note missing.”
We add flow arrows and reference SUDP standards, including how the pool deck, patio, or new structure will convey stormwater.
“Lot coverage calculation missing or does not match zoning district limit.”
We calculate lot coverage and verify against your zone’s cap.

Why Denver Is Different – What You Need to Know (And What We Handle)
Denver’s permit requirements go beyond what most homeowners expect. Here are the real pain points that cause delays:
ADU rules are strict and not intuitive. An ADU must be smaller than the primary dwelling, fit within the rear 35% of the lot, and meet specific rear and side setbacks (10 ft for 1‑story, 20 ft for 2‑story). A two‑story ADU is allowed only where a two‑story primary structure would be allowed.
Stormwater management is mandatory. Denver requires sewer use and drainage permits (SUDP) for pools, ADUs, and any project that alters existing drainage. Your site plan must show how water flows off the new construction.
Floodplain notes are required even outside flood zones. The city enforces Chapter 114 of the Denver Code. The FEMA panel number must be on the plan.
Lot coverage is strictly enforced. Many homeowners assume they can use their entire lot. The zoning district cap – often 40–50% – applies, and exceeding it means a variance process that takes months.
Alley access is preferred. Where an alley exists, the city generally requires driveway access from the alley rather than the street. The site plan must show this correctly.
You do not need to learn any of this. We do the research, and you get a plan that passes.
Local Permit Story – Denver ADU Rejected Twice, Fixed in 24 Hours
Project: Detached ADU in a single‑unit zone district in Denver
Problem: The homeowner attempted to use a national online service. The first site plan omitted ADU size limits and the required 20‑foot rear setback for a two‑story ADU. Rejected.
Second rejection (after homeowner tried to fix it): The revised plan added the rear setback but still showed the ADU exceeding the primary dwelling’s total floor area – a clear violation of the Denver Zoning Code. The reviewer also flagged “missing grading notes” and “no stormwater management plan.”
What we changed:
Verified the primary dwelling’s zoning allowance and reduced the ADU size to comply
Adjusted the ADU placement to meet the 20‑foot rear setback requirement
Added SUDP notes, flow arrows, and stormwater management language
Added the FEMA panel number (Zone X, Panel 08001C0385J)
Included the required driveway and alley access details
Outcome: The homeowner resubmitted our plan. Denver P&D approved it on the next review cycle. Total delay saved: 5 weeks. The homeowner avoided a second trip to the permit counter and additional application fees.
