Portland Site Plan – $89, 24‑Hour Delivery, Pass City Review
You need a site plan. Portland’s Bureau of Development Services (BDS) needs it to be complete. You don’t have to learn the zoning code. We already know it.
You booked the contractor. You cleared the weekend. Then Portland sends back a correction letter. “Tree preservation not shown.” “ADU exceeds 800 square feet.” “Stormwater management missing.”
Another month in the resubmission queue. The crew moves to another job. Your project stalls.
That’s what happens when a site plan is incomplete. Portland reviewers don’t reject your project – they reject missing paperwork. We fix that before you submit.
Upload your address. We pull parcel records, verify setbacks, calculate lot coverage, add tree preservation notes, include stormwater language, and deliver a PDF that meets Portland’s checklist.
- 24‑hour turnaround for most residential plans
- Fixed pricing – $89 to $249
- Free revisions if BDS asks for changes
What Actually Gets Flagged in Portland (From Real Correction Letters)
Portland BDS reviews hundreds of residential plans every month. These are the most common reasons they send plans back – and what we include so you don’t get the same letter.
“Tree preservation plan missing. Protected trees not located. Removal requires mitigation.”
Portland has strict tree codes. We identify protected species, show driplines, and add preservation or replacement notes before you submit.
“ADU exceeds maximum floor area. Detached ADU limited to 800 sq ft (1,000 sq ft if affordability provision used).”
We verify your ADU size, height (max 20 ft), and lot coverage (50‑55% depending on zone) before you order.
“Setback measured from foundation, not eave.”
Portland measures to the furthest projection – roof overhang, gutter, chimney. Foundation measurement is always wrong. We measure from the eave.
“Stormwater management not shown. Grading and drainage plan required.”
We add flow arrows, retention notes, and reference Portland’s stormwater management manual – even for small additions.
“Flood zone reference missing. FEMA panel number required.”
Even in low‑risk zones, Portland wants the panel number. We add it every time.
“Easement shown without recorded instrument number.”
“Utility easement” alone gets rejected. We add book/page references from county records.
What Your Portland Site Plan Includes (And Why Each Item Matters)
You don’t need to learn Portland’s zoning code. You just need a plan that passes. Here’s what we deliver – and why reviewers check for it.
| What We Include | Why Portland Reviewers Flag It |
|---|---|
| Property lines from recorded plats | GIS data is rounded. Reviewers compare against legal documents. We use exact dimensions. |
| Setbacks from the eave | Foundation measurements fail every time. We measure from the furthest projection. |
| Easements with book/page numbers | “Utility easement” alone gets rejected. We add recorded instrument numbers. |
| Tree preservation notes | Portland enforces tree codes. We identify protected trees and add required language. |
| ADU size, height, lot coverage | Detached ADU: 800 sq ft max (1,000 with affordability). 20 ft height. We verify before you pay. |
| Stormwater management notes | Grading, flow arrows, retention – required for any project that changes drainage. |
| Flood zone + FEMA panel number | Required even for low‑risk properties. We add the correct panel. |
| Impervious surface calculation | Portland enforces hardscape limits. We calculate and show the number. |
| Seismic notes (where applicable) | Required for additions and new construction. We include standard language. |
| North arrow + engineering scale | Missing these? Rejected before review starts. We include them on every sheet. |
You don’t need to learn any of this. We handle it.
Real Portland Story – Homeowner Lost 6 Weeks to a Missing ADU Size Limit
Project: Detached ADU in Southeast Portland (R‑5 zone)
What happened: The homeowner ordered a site plan from a national online service. No tree inventory. ADU size was 950 sq ft – well over Portland’s 800 sq ft cap. No stormwater notes.
Reviewer sent back: “Tree preservation plan missing. ADU exceeds maximum floor area of 800 sq ft. Stormwater management not shown. Grading and drainage plan required.”
What we changed: We added tree preservation notes, reduced the ADU footprint to 800 sq ft, added stormwater flow arrows and retention language, included the FEMA flood panel, and verified setbacks from the eave.
Outcome: The homeowner resubmitted our plan. Portland approved it on the next review cycle. Total delay saved – 6 weeks. Avoided additional plan check fees.

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.
-
Stop Waiting. Stop Guessing. Get a Plan That Passes.
Based on Portland Zoning Code, Title 11 (Trees), Stormwater Management Manual, and BDS submittal requirements as of June 2026. We keep up with the rules so you don’t have to.
