How Lakewood Handles Accessory Structures: A Practical Guide

Lakewood maintains 36 local ordinances across all categories, and 3 of those deal specifically with accessory structures. Here is a breakdown of what the city actually requires, what is prohibited, and where Lakewood falls on the strict-to-permissive spectrum compared to other cities.

ADU Rules

Lakewood allows 2 ADUs per lot consistent with HB 1337 (2023). Detached ADUs require a minimum 4-foot setback from rear and side yard boundaries. Parking is not required for ADUs within ¼ mile of a Pierce Transit bus route or ½ mile of Sound Transit Lakewood Station.

Key details: ADUs Per Lot: 2 (HB 1337). Setback (Rear/Side): 4 feet minimum. Parking: Waived near transit (¼ mi bus / ½ mi Sound Transit). HOA Restrictions: Void if created after July 23, 2023. Code: LMC 18A.40.110; HB 1337.

Unpermitted ADUs face stop-work orders and removal or legalization requirements. Fines of $500–$2,000 apply for unpermitted construction. Properties with illegal ADUs may face title issues at sale.

Shed Rules

Sheds and accessory structures in Lakewood require a building permit if over 200 sq ft or if including electrical or plumbing. Structures must meet zone setback requirements from property lines.

Key details: Permit Required: Over 200 sq ft or electrical/plumbing. Setbacks: Per zoning district (LMC Title 18A). Topic: Shed Rules. Category: Accessory Structures.

Unpermitted structures receive a notice to either obtain a retroactive permit (with double fees) or remove the structure within 60 days. Fines of $100–$500 apply for non-compliance.

Garage Conversions

Garage conversions to habitable space in Lakewood require a building permit and must meet residential code standards. Conversion to an ADU is permitted under LMC 18A.40.110 and HB 1337 provisions.

Key details: Permit Required: Yes (building permit). ADU Conversion: Permitted under LMC 18A.40.110. Parking: May be waived near transit. Topic: Garage Conversions.

Unpermitted garage conversions face fines of $500–$2,000, mandatory permit acquisition (double fees), and may need to be restored to garage use if code requirements cannot be met.

The Bottom Line

Lakewood's accessory structures rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Lakewood is broadly strict or permissive.

Keep in mind that Lakewood can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
