Parking and Servicing

A secondary dwelling can be allowed by zoning and still need a workable parking arrangement, safe access, utility upgrades, drainage measures, or approval from another service authority. These questions depend on the property, the dwelling type, and the rules in force when you apply.

Start with the authority that controls the specific question. A city may set parking and site rules, while a fire service, water provider, electric utility, health authority, or conservation body handles a separate part of the project. A published service area or parking exemption does not establish that a particular lot has capacity or approval.

Find the right check

• Check local ADU parking requirements and waivers before assuming a space is required or exempt.
• Check lanes, alleys, driveways, and fire access when vehicle, pedestrian, or emergency routes matter.
• Review water, sewer, stormwater, and drainage checks for provider, connection, and site-specific requirements.
• Review septic, well, rural, and agricultural servicing when a property is not served by ordinary municipal systems.
• Check electrical service, addressing, and capacity before treating existing services as adequate.
• Check Vancouver’s 2026 rainwater and sewer rules for the city’s current permit transition and pathways.
• Review Toronto garden-suite fire-department access for the city’s published route criteria and alternatives.
• Compare Los Angeles parking exemptions and Pasadena parking and driveway access.
• Check Brampton ARU parking, Hamilton ADU parking, and London, Ontario site conditions.
• Review Albuquerque casita parking and access, St. Louis parking and utilities, and Arlington County’s parking study path.
• Check Hamilton water-service capacity and Madison detached-ADU utility capacity.
• Review Calgary secondary-suite electrical load and New York City utility controls.
• Prepare Edmonton’s secondary-suite access site plan for its local submission requirements.

Confirm the current rule with the responsible authority and apply it to the actual parcel and project design. These guides explain what to investigate; they do not establish a property’s eligibility, service capacity, permit outcome, or fire acceptance.
