Opening a Los Angeles Business in 2027? Check This Permit Route Before You Sign
Los Angeles has published tenant-improvement self-certification rules—but a change of use is excluded. Learn which questions to ask before your lease and opening schedule are fixed.
An available storefront or office can look ready for a quick refresh. The more important question is whether your intended business fits the space’s approved use, existing systems and accessible route. For a 2027 opening in the City of Los Angeles, a newer tenant-improvement permitting route may be worth discussing with your architect. It is not a promise of immediate approval, and it does not apply to every commercial conversion.

A verified 2026 program to evaluate for a 2027 project
On September 23, 2026, the City of Los Angeles Department of Building and Safety issued its Tenant Improvement Self-Certification Program Rules and Regulations, document MI-GI-003. The rules allow California-licensed architects separately registered with LADBS as Self-Certified Architects to certify eligible commercial tenant-improvement building plans in place of the standard building plan-check process, subject to screening, required clearances and audits.
This is a City of Los Angeles program, not a statewide fast-track rule. The eligibility matrix excludes projects proposing a change of use or occupancy, additions, foundation work and alterations to a building’s lateral or gravity system, among other exclusions. The department also states that standard inter-departmental clearances and field inspections remain mandatory.

Key takeaways
- Verify the existing approved use and your proposed use before assuming program eligibility.
- A California architect’s license alone is not the same as LADBS self-certification registration.
- Separate trade permits, accessibility, audits and final inspections still affect the project.
1. Start with the building records, not the new floor plan
The program requires the latest Certificate of Occupancy and relevant building-permit records. Those documents help establish whether the proposed project actually keeps the same use and occupancy. A leasing description such as “retail ready” is not a substitute for that review.
Ask the architect to screen the full eligibility matrix, including exclusions for unreinforced masonry and specified non-ductile concrete buildings that have not met the cited ordinance. The rules allow only limited associated structural work, such as qualifying non-bearing partitions and attachments. Do not treat the program as permission for a broad structural remodel.

2. Ask who will certify the plans—and who will build them
The rules distinguish the architect’s state license from the LADBS-issued self-certification registration. Ask your architect to confirm current program registration and whether the project is appropriate for this route. A general contractor does not become a Self-Certified Architect by offering tenant-improvement services.
The builder’s role includes reviewing access, sequencing, coordination and construction pricing with the design team. Confirm responsibility for existing-condition investigations, documentation and revisions. The professional certifications and owner affidavits described in the program deserve review by the relevant parties before submission.

3. Self-certification does not remove the rest of the permit process
MI-GI-003 requires complete plans and supporting documentation, eligibility screening and required departmental clearances. It states that a minimum of 10% of submittals will be selected at random for audit. The rules also address audits associated with inspection-found omissions or violations; owners should not assume an unaudited initial submission can never be reviewed.
Separate electrical, plumbing, HVAC, fire-sprinkler or elevator permits are still required where applicable, and separate plan check may be required for those scopes. The construction schedule must account for those reviews, inspections and closeout rather than treating the building-permit route as a guaranteed opening date.

4. Review accessibility before assigning the build-out budget
The California Division of the State Architect explains that a Certified Access Specialist, or CASp, can evaluate applicable construction-related accessibility standards based on a property’s age and improvement history. Ask whether an independent inspection would help define existing barriers and the proposed scope.
DSA also explains that both landlord and tenant can retain legal responsibilities under the ADA even where a lease allocates work between them. Have qualified counsel address the lease and a qualified professional assess the facility. Do not assume a lease allowance, a previous permit or the self-certification route resolves every access obligation.

5. Build the 2027 opening plan around dependencies
Make a list of the decisions and approvals needed before construction and occupancy: permitted use, landlord consent, complete design, required trade reviews, utility coordination, inspections and business-specific approvals. Assign each item to a responsible party and update the schedule when assumptions change.
LADBS’s tenant-improvement FAQ says a Certificate of Occupancy is not required for a TI project unless the permit is for a Change of Use. That does not mean a same-use fit-out can skip permit final or required inspections. A change-of-use project may need a different permitting path and is excluded from the self-certification program described here.
Before you commit to the space or announce the opening
- Obtain current occupancy and relevant building-permit records.
- Ask the architect to compare proposed use and scope with the full eligibility matrix.
- Confirm current LADBS self-certification registration if using that route.
- Identify accessibility issues and clarify lease responsibilities with qualified advisers.
- List separate permits, clearances, inspections and possible audit effects.
- Document assumptions behind the construction and opening schedule.
Frequently asked questions
Can every Los Angeles tenant improvement use self-certification in 2027?
No. MI-GI-003 is a City of Los Angeles program with a defined eligibility matrix and registration requirements. Changes of use or occupancy, additions and several structural scopes are excluded. Verify current rules and project eligibility with LADBS and your architect.
Does self-certification mean the contractor can skip permits or inspections?
No. It is a defined route for eligible building plans certified by a registered architect. Required clearances, separate trade permits, field inspections, permit final and audit provisions still apply.
Can DWD Builders guarantee approval or an opening date through this program?
No. DWD Builders can discuss construction planning and coordination with your design team, but eligibility, certification and approvals involve the appropriate professionals and authorities. Review the actual scope and dependencies before committing to a schedule.
