REVIEW YOUR RENTON PROPERTY

Turn an ADU idea
into a site-specific Renton plan

Use Renton’s ADU resources to start a focused property conversation. Compare a City model plan with a custom layout, then examine the proposed location, existing buildings, and the utilities needed for another independent household.

01

Test the PRADU route early

Renton offers pre-approved ADU model base plans. Compare the layouts with your household’s needs, then prepare a proposed location and yard photographs for a City pre-screening. A base plan still needs to fit the property.

02

Identify each utility provider

Renton’s utility guidance begins by identifying who provides water, sewer, and stormwater services. Confirm those providers and the proposed connection routes before budgeting trenching or service work; a Renton address does not tell the whole utility story.

03

Include the work between the street and cottage

A new residence may need site preparation, utility connections, or work in the public right-of-way. Renton separates these permit categories from the building itself. Review access, disturbed ground, and proposed service work together so they are visible in the construction scope.

BUDGET FOR YOUR RENTON PROJECT

Separate the plan from
Renton’s complete construction scope

A PRADU base plan is one part of the project. Budget separately for property-specific design, site preparation, service connections, permits, and construction before deciding which layout fits your goals.

Area planner only. Construction pricing for Renton follows review of the property, design, site work, fees, allowances and taxes in your written proposal.

Review the Renton scope ↗

Include the route
from street to residence

Review where services originate, how construction reaches the proposed unit, and what work occurs outside the building. Renton’s site, utility, and right-of-way considerations belong in the initial scope.

Questions for your Renton construction proposal
Scope itemWhat your proposal should clarify
Design & engineeringArchitect and engineering responsibilities, site documents, and any designer’s plan-license fees.
Permits & City feesApplications, review fees, required permits and who is responsible for each cost.
Site preparationExisting structures, demolition, excavation, access, drainage and any site-specific work.
Utility connectionsWater, sewer, electrical service, connection routes and any required upgrades.

THE SEATTLE DESIGN COLLECTION

Compare Seattle inspiration with
Renton’s own PRADU route

The Seattle ADUniverse reference includes 183 entries and 31 with plans, offering layout inspiration. Renton also has its own PRADU model plans and pre-screening process. Neither a Seattle catalog entry nor a selected base plan establishes that your Renton property has received local project approval.

These 10 designs are listed as pre-approved in Seattle’s gallery. Site-specific permitting and a plan license from the designer are still required.

START WITH YOUR PROPERTY

Compare Renton’s three
routes to an ADU

A City model cottage may offer a starting point, while an attached unit or conversion may better suit the property. Test each approach against independent living and site work.

Tell us about your property
01A backyard cottage using a suitable layout

Compare Renton’s PRADU options with a custom cottage, using yard photographs and a proposed location to identify the site questions that a plan alone cannot answer.

02An attached unit close to the household

Consider a connected residence where a new addition can accommodate independent rooms. Resolve the entrance and the relationship to existing living spaces before selecting finishes.

03A basement, attic, or garage conversion

Renton identifies existing-space conversions as possible ADU approaches. Inspect the structure and service needs to understand the work required for a complete independent unit.

FROM YOUR RENTON ADDRESS TO HANDOVER

Take the Renton proposal
from screening to handover

A useful sequence brings the site and service questions forward. The selected plan, required reviews, utility providers, and existing conditions determine the work and its timing.

  1. 01

    Prepare the Renton property brief

    Identify the intended household, assemble yard photographs and available records, and mark a possible location for the new residence.

  2. 02

    Compare and adapt the layout

    Review a suitable PRADU base plan or a custom approach, coordinating the footprint with entrances, outdoor space, and utility routes.

  3. 03

    Coordinate City and utility requirements

    Establish the building review path and any site, utility, or right-of-way permits needed for the specific work and service providers.

  4. 04

    Build the residence and its connections

    Carry out the agreed site preparation, utility coordination, structure, and interior construction using the approved documents and recorded selections.

  5. 05

    Complete the closeout together

    Address required inspections and agreed finishing work, review the installed systems, and provide the records needed to understand the completed residence.

What determines the Renton schedule?

The design team, reviewing authority, site conditions and material lead times shape your Renton sequence. We refine milestones as the documents and permit path become clear, then confirm the construction schedule in the agreement.

BEFORE YOU BEGIN

Renton PRADU, conversion,
and utility questions

Renton’s base plans can help start the discussion, but the property still matters. These answers explain what to prepare and which service questions need a closer look.

Ask us your question
What should I prepare for Renton’s PRADU pre-screening?

Prepare yard photographs in four directions, the proposed ADU location, and your preferred model and style. Available surveys, easements, agreements, or professional studies can help City staff understand the property.

Are Renton’s free ADU plans a complete construction budget?

No. PRADU provides model base plans. Property-specific design, utilities, and construction still need a defined scope. We recommend pricing those items alongside the selected model before setting the project budget.

Does Renton allow ADUs inside an existing home or garage?

Renton includes basement, attic, and garage conversions among possible ADU approaches. Suitability depends on the existing space and the permits and construction needed to establish an independent residence.

Can all Renton ADU utility work use one City connection process?

First verify the providers. Renton directs applicants to its utility permit procedures when the City is the relevant water, sewer, or stormwater provider. Other providers and work in the right-of-way may require separate coordination before construction can proceed.

How is the construction price established for my Renton ADU?

Your Renton price is developed around the selected layout and property review. The written proposal should identify design responsibilities, site preparation, utility connections, finishes, allowances, exclusions, fees and taxes. The area planner on this page does not calculate a construction price.

What support comes with the finished Renton construction work?

Oleg & Sons Bellevue Home Remodeling provides a 2-Year Workmanship Warranty. For your Renton project, we review the agreed construction responsibilities, final walkthrough and applicable warranty terms in the project documentation.

Housing shaped by rivers, industry, and wartime growth

Renton stands on the homelands of the Duwamish people, near the historic meeting of the Black and Cedar rivers and Lake Washington. Coal mining and logging helped drive its incorporation in 1901. Industrial growth continued with the arrival of PACCAR and, later, Boeing in 1941. Wartime production brought rapid population growth and new housing, including development in the Highlands and Cedar River Park. That history gives Renton a varied residential setting rather than one uniform lot type. An ADU proposal should respond to the particular house and neighborhood, comparing an existing-space conversion with a separate cottage and reviewing utility service before settling on a design.

Renton’s housing history meets another living option

Renton offers a starting point through its Permit Ready ADU program. Compare a City base plan with a custom layout, then review the site and utilities needed to serve another residence. A City model cottage may offer a starting point, while an attached unit or conversion may better suit the property. Test each approach against independent living and site work.

Industrial growth, established neighborhoods, and a local model-plan program with site-specific decisions still ahead.

Confirm the actual jurisdiction and current development requirements for the Renton property. A mailing address alone does not establish the permit authority.
