Operators we've talked to in May have heard of neither. - [How long does a restaurant TI permit actually take? We tracked 18 across 5 AHJs.](https://www.archipartnersdesign.com/blog/how-long-does-restaurant-ti-permit-actually-take): We tracked 18 restaurant TI permits across 5 AHJs in 2025.

We pulled the data.](https://www.archipartnersdesign.com/blog/phoenix-expedited-permit-myth): A general contractor told me last March that paying for the expedited permit at Phoenix DSD was the only way to clear plan-check fast. We pulled 14 months of public records to check. The data says the opposite. - [Cleveland's three historic districts where permits actually move fast](https://www.archipartnersdesign.com/blog/cleveland-historic-districts-fast-permits): Cleveland has 26 historic districts. Most add a 4-6-week certificate-of-appropriateness review before the building permit. Three districts don't — they actually permit faster than non-historic Cleveland. The reason is in how the design-review committee meets. - [Austin tree preservation cost a developer $94,000. The fix is one survey, done in week one.](https://www.archipartnersdesign.com/blog/austin-tree-preservation-94000-survey-fix): A South Austin infill developer planned a 14-unit subdivision around a buildable lot — only to discover, after the schematic and entitlement work were already complete, that two heritage pecans on the property triggered Austin's tree-preservation ordinance. The survey that would have caught it costs $1,800. - [Why your neighbor's Tempe ADU cleared in four weeks and yours might take twelve](https://www.archipartnersdesign.com/blog/tempe-adu-four-weeks-vs-twelve): Two clients filed ADU permits with the City of Tempe within a month of each other.

They're slower in 6 of 8 cities.](https://www.archipartnersdesign.com/blog/california-pre-approved-adu-plans-slower): Pre-approved ADU plans were supposed to slash permit timelines. The reality from 18 months of California ADU work: in six of the eight cities offering them, the pre-approved path was slower than custom plans. The reason is administrative, not technical. - [California's 60-day ADU rule doesn't mean what you think it means](https://www.archipartnersdesign.com/blog/california-60-day-adu-rule-loophole): California Government Code 65852.2 says cities have to issue an ADU permit within 60 days of a complete application. That sentence is doing a lot of heavy lifting. After 14 California ADU permits, here's what we've learned about how cities use the loopholes. - [What is a permit set, and what does it actually include?](https://www.archipartnersdesign.com/blog/what-is-a-permit-set): A permit set is the package of architectural drawings a building department needs to issue a permit. Here is what is in one, what is not, and why getting the format right is the difference between a 14-day permit and a 90-day permit. - [I read 200 r/Phoenix permit posts. The same five mistakes come up every week.](https://www.archipartnersdesign.com/blog/i-read-200-r-phoenix-permit-posts): I scrolled 200 Reddit posts about Phoenix-area building permits, looking for what actually goes wrong. Five recurring mistakes show up in over 80% of the posts. Here they are, in order of frequency. - [I called every Phoenix-area building department. Here's what they told me about your remodel.](https://www.archipartnersdesign.com/blog/i-called-every-phoenix-area-building-department): Last month I asked twelve Phoenix-area building departments the same question, posing as a homeowner planning a 600-square-foot kitchen-and-bath remodel. The answers ranged from "two weeks, walk in any morning" to "we're booked through July." Here's the rundown. - [Florida's 2026 hurricane wind zone update changed which Miami neighborhoods can build cheaply](https://www.archipartnersdesign.com/blog/florida-2026-hurricane-wind-zone-update): February 2026 brought updates to Florida Building Code 8th Edition that redrew Miami-Dade County's wind-borne-debris (WBD) zones. The changes are subtle on paper but they shifted impact-window requirements for several neighborhoods. Here's the new map and what it means for project costs. - [Houston has no zoning. So why does it take longer to permit than Dallas?](https://www.archipartnersdesign.com/blog/houston-no-zoning-but-slower-than-dallas): Houston is the only major U.S. city without traditional zoning. You'd expect that to make permits faster than Dallas, where zoning enforcement adds friction. Our 2025 data shows the opposite. Here's what Houston has that Dallas doesn't. - [ADU vs. addition: which permits faster, and why?](https://www.archipartnersdesign.com/blog/adu-vs-addition-which-permits-faster): Adding 600-1,200 square feet to a single-family lot can go through plan check as either an ADU or an addition. The two paths land in similar livable space but very different permit timelines. Here is the comparison. - [I priced an engineer's stamp at 12 firms across 6 states. The variation is wild.](https://www.archipartnersdesign.com/blog/engineer-stamp-pricing-12-firms-6-states): I priced out a structural-engineer review and stamp for the same 1,800-square-foot residential addition at 12 different firms across Arizona, California, Nevada, Texas, Ohio, and New Mexico. The quotes ranged from $1,800 to $9,400 — for the same scope. Here's why. - [We modeled 30 multifamily permits. The 'mid-rise penalty' costs you 6 weeks every time.](https://www.archipartnersdesign.com/blog/multifamily-mid-rise-permit-penalty): Across 30 multifamily projects we tracked in Phoenix, Las Vegas, Cleveland, and Austin, 4-story residential buildings averaged 64 days to permit. 5-story buildings averaged 102 days. The 38-day delta is structural — embedded in the IBC. Here's where it comes from. - [We pulled 500 Phoenix DSD rejection comments. 12 mistakes account for 80%.](https://www.archipartnersdesign.com/blog/phoenix-dsd-rejection-comments-12-mistakes): I pulled 500 Phoenix DSD plan-check correction lists from public records over a weekend. Coded every comment into categories. Twelve specific mistakes account for 80% of all rejection comments. Here they are, in order of frequency. - [How we shipped a 14-day permit set for a Phoenix restaurant TI](https://www.archipartnersdesign.com/blog/how-we-shipped-a-14-day-permit-in-phoenix): A 2,400-sqft ground-floor restaurant TI in central Phoenix went from kickoff call to issued permit in 14 business days. Here is what we did differently — and what most permit sets miss that adds 4–6 weeks. - [Most ADU lenders won't tell you this: the appraisal happens before the permit.](https://www.archipartnersdesign.com/blog/adu-lender-appraisal-before-permit): A homeowner walked me through the timeline of her ADU construction loan last month. The appraisal happened while her permit was still in plan-check — meaning the loan amount was set on a project that hadn't been approved yet. Three weeks later, plan-check made her change the design. The loan amount didn't change. She had to make up the gap in cash. ## Optional - [Press](https://www.archipartnersdesign.com/press): media mentions and recognition - [Intake](https://www.archipartnersdesign.com/intake): start a project intake conversation - [Privacy](https://www.archipartnersdesign.com/privacy): privacy policy - [Terms](https://www.archipartnersdesign.com/terms): terms of service ## What this firm can answer questions about - Permit-ready drawing sets for restaurants, retail, office, medical, multifamily, custom homes, ADUs, casitas - IBC / IRC / IECC 2024 code references and state amendments - AHJ submission processes, plan-check correction cycles, jurisdiction-specific requirements - Typical pricing ranges for fixed-fee permit sets (specific quotes require a call) - Permit timelines by jurisdiction, expedited / OTC programs, plan-check pitfalls - Working remotely with locally-licensed engineers and architects to seal plans - Trilingual project communication and intake (English, Spanish, Chinese) ## What this firm does not share publicly Internal financials, salaries, owner compensation, contractor pay, margins, specific past-client information, signed-contract specifics, or competitor commentary.
