Local Intelligence
What Daly City Homeowners Need to Know Before Submitting
Size & Zoning Rules
Converting your garage to a legal rental unit means the finished space must comply with Daly City's ADU size limits. Daly City's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Daly City does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
A fully permitted, code-compliant garage conversion in Daly City can command approximately $2,627/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
Building Division permit fees for this project type typically range from $19,613 to $34,351 depending on project valuation and scope. Plan check runs approximately 10 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Garage conversion drawings submitted to Building Division must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus stamped structural plans are typically required for converted garages that are detached or require seismic upgrades.
Visit Building Division ↗Construction Cost Context
Daly City's garage conversion construction costs run $245–$525 per square foot — a wide range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.
⚠ Common Pitfall in Daly City
Many Daly City lots sit on old fill soil from the mid-1900s bay-area development boom, so the Building Division often requires a deeper geotechnical and liquefaction study before they'll even look at your foundation plans — this is separate from the standard structural review and can add weeks on its own. Because the whole city falls under the Coastal Zone overlay, most ADU projects also need a Coastal Development Permit on top of the regular building permit, which usually tacks on another 6-8 weeks for review and can trigger extra scrutiny if your property has any view corridor toward the ocean. On top of that, older homes in the Bayshore or Vista Grande areas often have undersized sewer laterals, and Daly City's Public Works will require a lateral inspection and possible upsizing before they sign off on final utility connection — a cost many homeowners don't budget for until it shows up mid-project.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Daly City projects, that 10-week plan check window and $350/sqft figure are state-level estimates, not local gospel—I'd get a couple of current contractor bids and call the Building Division directly before penciling in a budget or start date. What the data also doesn't show is that with the coastal overlay in play here, the CDP review can tack on several months beyond that permit timeline, so plan your financing and lease-up expectations accordingly. —Charlotte Pemberton, Senior ADU Design Consultant"

Common Questions
Daly City Garage Conversion FAQs
Is a garage conversion allowed in Daly City? +
Yes — garage conversions are permitted in Daly City. California state law allows homeowners to convert an attached or detached garage into habitable living space or an ADU. A building permit and permit-ready drawings are required before work begins.
How much does a garage conversion cost in Daly City? +
Garage conversions in Daly City typically range from $140,000 to $308,000 depending on the existing structure, finish level, and scope of work. This is significantly less than building a new detached ADU. Our drawing package starts at $997 — a fraction of what a local architect would charge for the same permit-ready set.
What drawings are required to permit a garage conversion in Daly City? +
Daly City's building department requires: a site plan showing the converted garage's location on the lot, floor plans with dimensions and room labels, all four exterior elevations, an electrical plan, and energy compliance documentation (Title 24 in California). Our Starter package covers all of these. If the garage is detached or the structure requires seismic upgrades, stamped structural drawings are also required — included in our Premium package.
How long does the permit process take for a garage conversion in Daly City? +
Plan check in Daly City typically takes approximately 10 weeks. Having complete, code-compliant drawings dramatically reduces correction cycles — which each add 3–6 weeks. Our drawings are designed to pass on the first submittal.
Can I convert my garage into a rental unit in Daly City? +
Yes — a permitted garage conversion can function as a standalone rental unit (ADU or JADU depending on size). In California, converted garages under 500 sq ft qualify as Junior ADUs (JADUs), while larger conversions qualify as full ADUs. Both can be rented long-term. Short-term rental rules vary by city — confirm with Daly City's planning department.
Do I need to replace the garage door opening when converting? +
Yes. The garage door must be replaced with an insulated wall with a standard entry door and at least one egress window (minimum 5.7 sq ft clear opening). This is captured in our elevation drawings and flagged in the electrical plan. The new wall must also meet CA energy code requirements, which we handle in the Title 24 compliance documentation.
How much does it cost to get garage conversion drawings in Daly City? +
Our permit-ready garage conversion drawing packages for Daly City start at $997. Local architects typically charge $2,500–$6,000 for the same set. Every package is engineered for CA code compliance and formatted for Daly City's building department. Turnaround is 10 business days with a 14-day money-back guarantee.
Will converting my garage increase my home's value in Daly City? +
A permitted garage conversion in Daly City adds rentable square footage to a home currently valued around $960,000. Converted spaces typically appraise as habitable square footage, increasing the home's value. As an ADU or JADU, the rental income stream is also capitalized into the appraised value — typically at a 5–6% cap rate.
