How the local-rule search works.
The search uses your location and project to find public documents from official authorities. AI helps research and summarize the rules found.
Match the location and use
A home, an ADU and a storage container need different checks. City limits and county areas are treated separately; a mailing address alone does not establish jurisdiction.
Summarize the sources
The result links a research summary to official sources found. A summary can miss amendments, exceptions or context. Read the original document and confirm the rule and its applicability with the responsible authority before relying on it for your project.
Show what remains unknown
Unconfirmed rules and property-specific questions stay visible. A search result is an information summary; it does not approve a parcel or issue a permit.
Each published example shows its document-check date. Search results show their research date; local requirements can change.
The order matters
From a plot to a permit-ready project.

Choose the right approval route
Factory-built or built on your lot?
Clarify the division of work before signing. Residential use, finished layout and site conditions matter in either route.
Built or converted on site
Agree the structural and foundation design, trade permits and inspections with the local team. Include openings, reinforcement, insulation and finished room sizes.
Before work: identify who signs and submits the plans.
Completed partly in a factory
Ask whether a state factory-built program covers this unit. Confirm factory inspections, site foundations, connections and local occupancy responsibilities separately.
Before manufacture: confirm the accepted review route.

Austin, Texas — confirmed city jurisdiction
New single-family dwelling, converted and assembled on site
Can I build a container house on my Austin lot using the ordinary residential application?
Permit answer
Residential building permit required
A new dwelling goes through Austin Residential Plan Review. Container construction does not establish that the proposed house is acceptable on this particular lot.
Conditions to check
- Review covers the 2024 IRC, Austin's local amendments and applicable land-use requirements.
- New-construction drawings include foundations, framing and wind bracing; floor plans identify rooms, openings, fixtures and alarms.
- Resolve expired permits and establish the legal lot before progressing the application.
Next steps
Prepare the application
Use the New Construction or Addition web form with the plot plan and coordinated construction drawings.

- The parcel's zoning eligibility and the container's structural design have not been assessed in this example.
Washington State — installation city or county not specified
Container dwelling completed off site under the modular-building program
If the manufacturer obtains Washington approval, can the finished home go straight onto my land?
Permit answer
Factory approval and local site approval are separate
A covered modular building needs L&I approval and its insignia before leaving the factory. That approval does not decide whether the dwelling can be installed on your lot.
Conditions to check
- First establish that the actual unit falls within L&I's modular-building program; a container label alone does not do this.
- Standard review and review by an L&I-approved professional both require L&I processing and inspections.
- The local building department approves the actual site and foundation, even when those appear in the factory design package.
Next steps
Coordinate factory plans
Have the manufacturer submit the residential design, structure, services and location-specific design criteria.
Washington L&I
Document factory approval
Arrange factory inspections and verify the approval and insignia for the unit before shipment.

Obtain site approval
Submit the actual site and foundation details locally, coordinated with the approved module.

- The installation jurisdiction, land-use eligibility and local permit package remain undetermined.
Texas — installation municipality not specified
Factory-built permanent dwelling within the Texas IHB program
The supplier offers an IHB-approved container home. What still needs approval at the installation site?
Permit answer
Approved modules still need a compliant installation
Where the home qualifies as Texas industrialized housing, the approved modules, permanent foundation and installation inspections form separate parts of the project. Applicable local site requirements remain.
Conditions to check
- Confirm IHB coverage and module certification; the program is distinct from HUD manufactured housing.
- The installer needs industrialized-builder registration or an eligible installation permit; an own-use purchaser may qualify for the latter.
- Coordinate manufacturer load points with a foundation design sealed by a Texas engineer or architect.
Next steps
Verify the supplied home
Obtain the approved module drawings and identification, and establish who holds the builder registration or installation permit.

Keep the project moving
Before ordering. Before delivery.
Checkpoint 01
Before ordering
- Confirm residential use and the review route.
- Name the designer, permit applicant and inspection responsibilities.
- Put shell condition, drawings, exclusions and change costs in the contract.
Checkpoint 02
Before delivery and move-in
- Confirm required permits and the installation sequence.
- Have foundations, lifting access and service connections ready.
- Complete required inspections and occupancy release before moving in.
An inquiry or a supplier’s quotation is not an issued permit. Keep the authority’s written decisions with your project records.
Quick answers
Before you commit.
Is a container home treated like a storage shed?
No. Describe the residential use from the start. A home or ADU needs its own land-use and building review; the rules for an unoccupied storage container do not determine that route.
Does a factory-approved unit cover my whole project?
Confirm exactly what the approval covers. Local land use, foundations, utilities, installation and occupancy can remain separate. Ask who inspects each part before signing the package contract.
Can I buy the containers before applying?
You can make that commercial decision, but do not assume the selected shells or design will be accepted. Establish the approval route first and put redesign, storage, cancellation and refund terms in writing.
Do I need an architect or engineer?
Ask the permit authority which licensed professionals and sealed documents it requires for this project. Container alterations, connections, foundations and local design loads need coordinated assessment.
When can I move in?
Ask which final inspections, utility releases and occupancy approval apply. Delivery or completion of the factory work alone does not authorize occupation.
