Most construction activities will require a permit to confirm that the proposed work meets the legal requirements of the State and Local Jurisdictions. This is achieved through reviewing plan documents, providing approval, and then inspection to verify that the construction meets the approved plan. Please review our Permit Overview tip sheet which provides a general outline of the typical permit process.
Each section below provides examples of work that may be exempt from a permit and/or examples of when a permit is required. To confirm if a permit is required for your project, please contact our staff to discuss: https://www.tacomapermits.org/contact-us

SITE DEVELOPMENT (ON-SITE WORK, PRIVATE PROPERTY)
Onsite Activities Requiring a Site Development (SDEV) Permit
The table below outlines site activities and scopes that would require an SDEV permit. Continue reading this tip sheet for information on the further classification of Major and Minor SDEV permits.
This information is also available as part of the Stormwater Management Manual, Chapter 3.
Site Activities Requiring an SDEV Permit | |
Site Disturbing Activity |
|
Onsite Utility Work* |
*Utility permit(s) are required in addition to an SDEV; read below for information on other permits that may be needed |
Building-related work |
**An SDEV is usually needed in relation to a BLDCN or BLDCA even when site work falls below the area thresholds listed above ** Building Permits for new residential dwellings (BLDRNs) are generally issued with a Site Development Permit (SDEV) that is created internally after the review is complete. |
A Site Development Permit is not required for the following unless such work is in a Critical Area governed by TMC Chapter
13.11; however, all such work is subject to application of the Recognized Engineering Practices to mitigate the anticipated conditions:
- Grading, to include grubbing, less than 50 cubic yards or an area not to exceed 7,000 square feet, whichever is less, performed in a two-year period that is not part of a building project or new impervious surface that requires a permit.
- Clearing less than 7,000 square feet in area meeting at least one of the following:
- Activities in preparation for site surveying, or other associated work. This does not permit grubbing or activities that cause soil disturbance.
- Clearing within ten feet of the perimeter of buildings.
- General property and utility maintenance, landscaping, or gardening in pre-existing developed land.
- An excavation below finished grade for basements and footings of a building, retaining wall, or other structure authorized by a valid building permit. This shall not exempt any fill made with the material from such excavation or exempt any excavation having an unsupported height greater than five feet after the completion of such structure, or exempt any grading over 50 cubic yards.
- Refuse disposal sites controlled by other regulations.
- Hazardous waste remediation under the jurisdiction of other agencies.
- Excavation on private property for wells or tunnels. Backfill is also exempt, provided it is not transported off site, or the backfill is not imported from off-site. Other filling with the material from such excavation requires a permit. This does not exempt the Contractor from being required to follow Recognized Engineering Practices.
- Mining, quarrying, excavating, processing or stockpiling rock, sand, gravel, aggregate or clay where local regulation is preempted by state or federal law. Such operations shall follow Recognized Engineering Practices and be in compliance with the COTSWMM.
- Exploratory excavations under the direction of a civil engineer or geologist. This shall not exempt any fill made with the material from such excavation. Clearing or grading to construct an access road to an exploratory site shall require a permit if construction requires more than 50 cubic yards of grading or disturbs an area more than 7,000 square feet, whichever is less.
- Clearing associated with routine maintenance by utility agencies or companies. This does not exempt the utility agencies or companies from being required to follow Recognized Engineering Practices.
- Clearing or grading in the right-of-way associated with street, alley, or sewer work approved by the Public Works Department or road maintenance conducted in accordance with the Regional Road Maintenance Program.
- Removal of trees or other vegetation, which cause sight distance obstructions at intersections so determined by the City of Tacoma Traffic Engineer.

- Forest practices under the jurisdiction of other agencies.
